If you guys are thinking of doing this be sure to get a power bank that Explicitly says Pass-Through Charging as the author of this video states. Most of the cheap USB powerbanks on eBay, Amazon, etc. do not have this feature because it requires more components to make and is more expensive. This is important because what the cheap ones do is always take power from the battery even when the powerbank is plugged in for charging. This means the battery is continuously being discharged and charged which will wear out the battery prematurely. Thanks for posting this video & Happy New Year !
Yes had a similar question for the uploader. I have a Lenovo pa10400 power bank and I am able to charge and discharge it simultaneously. However I want to be sure if it is actually pass through charger or is it just taking power from the battery and powering the router and then the power bank charging it self when the battery drops below 100. Pass through charging should simply connect the power input to the out of the power bank unit if the power bank itself is fully charged. If this doesn't happen then it will simply keep consuming battery cycles of the power bank as it will keep charging as soon as it drops below 100.
A new (2020+) version of this trick is to use a USB-C PD power bank with passthrough charging, combined with a "PD emulator" or "PD decoy" adaptor, to create custom voltages (e.g. 9V or 15V or 20V) at high power (e.g. up to 100 watts). This can power some more beefy electronics!
This is a lot of electronics stuff i don't understand. Can you please specify which devices exactly to buy and recommendations, also maybe how to set it up, thanks
@@olukolatimidavid8318 I know I am late but, what this user wanted to say is that: 1)Nowadays most phones to charge quickly, they require larger amounts of power. So, what companies did was, they made it so that devices can receive and transmit more power through usb. Usually, the standard for usb is 5v 1a, but most phones can accept 12v 1.5a or more through usb. Coincidentally, that's the voltage most routers/modems run on. 2)Thus, most smartphone chargers and powerbanks have to communicate with the phone to agree on what voltage is acceptable. If you look at the specs on your phone charger/powerbank, you will see that it might say that it outputs a wide range/variety of voltages. 3)So, what some smart people have done is, they took the little chip that makes the agreement between the phone and the charger, they put it on a small board that can accept usb input and output with various other ways (ie usb, dc jack etc) and this way they managed to create their own ups out of a powerbank. You can usually find these boards really cheap on sites like aliexpress with various names (pd decoy, pd trigger, qc trigger etc). You can buy a board like this, find some old power brick that fits in your router's/modem's power jack, cut and strip the cable, wire it to the board's output (be careful with the polarity, the device you want to power (or the power brick of said device) should have an image that shows the polarity. Usually, red is positive and black is ground/negative), set it up to its correct voltage (the board should come with a manual. If not, consult the seller),connect your powerbank on the board and the other cable to your router/modem and boom you just made a ups for your router/modem. If you don't understand how this all works, I would suggest you consult a more electronically savvy person to help you build it.
excellent i was searching for this type of solution from last few months and was ending up with big UPS, but this compact and smart idea is very great, thanks alot dear
This is a very good concept, but it doesn't always work. I tried this myself, and I didn't have much luck. 2 out of the 3 routers I tried failed to function. The first one I tried was my main modem/router combo, which didn't work. Then I tried my standard inexpensive Cisco router which also failed to function. The one that I got to work was an old Westwood modem/router combo from my old DSL connection. I checked and made sure the polarity was correct and I checked my multimeter to confirm my wiring was correct and it tested 5.1 volts positive on inside and negative outside of the barrel connector. I tried a couple different power banks too but the results were the same. If anyone wants to try this, I definitely recommend that you do NOT cut up your main wire, but instead buy that terminal he used in the video, or cut up an old one that you don't use anymore, because there is no guarantee that this will work for you.
What's the maximum output of your powerbank, 1A or 2A? Did you use a good quality USB cable with thick power wires inside? What were the power ratings on the 2 devices it didn't work with? And yes, cutting up an old unused cable would be better than cutting up your current one. Most people have an old power supply in a draw that has a matching DC barrel connector.
Gadget Addict The power banks I tried were up to 2.4 amps, I tried the 1 amp port and the 2.4 amp port. The first All were 12 volt requirement and the 1st one had a 1.5 amp input and the other 2 had roughly 1amp input, one of the 1 amp ones did work
Really great detailed video. But I still have a question. Is it safe to keep powerbank charging all the time ? Won't it create heating issue or degrade of battery ?
Something I forgot to mention is that ideally you want to use a USB cable with thick wires inside. If the wires aren't so thick, make the cable shorter.
Gadget Addict Great video 🖒🖒🖒🖒🖒. What Powerbank do you reccomend as I'm using a PLDT Fibr Modem DC 12V/2A? After watching I tried it but it's not working. I am using Royqueen Powerbank 20,000 Mah and it's working charging my phone the same time charging my powerbank.

thanks a lot you just saved me from paying 50$ , i was lucky i had this cable that you custom built it , first it did turn on with no internet connection , i tried your tip about using short cables and it worked !!! thanks a lot
Notice: for illustrate real ups functionality you should look for a powerbank that keeps discharging when in use. (some of them do "power reset" for 1 second when the main power stop charge the powerbank)
for fibre routers and ONT you can get 2 USB to DC cables with a step up power module to convert the USB 5v to a proper 12v 2.1A input. Li-on power banks are cheaper than ever, I can buy a 60 000mah power bank with multiple USB and USB-C ports with passthrough charging and fast charge capabilities for about $65. In countries like mine where we lose power from 2 to 4hrs at a time multiple times a day this works wonders and is cheaper than router UPS options with a lot less capacity.
What i observe about this method is it might work 50/50. Imagine you have 12v light bulb powering 5v only. Youll never get that bright power output of 12v so there is a performance lost here. In this case using 5v only in 12v gadget. Yes led will work cause it uses low voltage but some components in board might not work properly. It doesnt mean led light up at 5v will perform 100% of system. Like what i said in some gadget this might work. Good review.
Thankfully most budget routers provided by ISPs are dropping the voltage down to 3.3V for the internals. So the 5V works fine. But you're right, it wont work for every modem/router and some do require the higher voltage :)
Cool idea and you don't have to butcher a USB cable or fiddle with an adapter at all. They make USB to DC cables, I actually bought one recently so I could charge my hand vacuum in my car with USB.
Hi Gadget Addict. Great idea! Simple, cheap and works. I would like to contribute to your idea, with the suggestion of using a power bank with quick charge 2 or 3 capabilities, and connecting a quick charge trigger module in the USB port of the power bank. With this setup, you can configure the voltage the power bank deliver, from 3 volts to 12 volts.
Had a question about the power bank ups suggested by you. Is it a good idea to have this as a permanent solution? What are the chances of fire, due to continued charging of the power bank and the router? Have you used it for a long time and found any pointers that you can share. Thanks
Cool video to show off your power bank and router collection. Nice idea. I have my router on a UPS and the lead acid battery seems to be dead now so would need this alternative.
you always have the nicest gadget (referring to usb watt meter 'cause I've been looking for a decent one for a long time) anw. where did you get or what do you exactly call that round adaptor? I'm definitely going to make this project. thanks for sharing this.
You can find the little connector by searching 'DC Barrel Jack terminal'. I can't remember where that specific watt meter came from. I think it's from eBay. The portapow advanced meter is still my fave.
I think your video is awesome. I have a Lenovo pa10400 power bank and I am able to charge and discharge it simultaneously. However I want to be sure if it is actually pass through charger or is it just taking power from the battery and powering the router and then the power bank charging it self when the battery drops below 100.

Hello, Very interesting idea/solution. One question to check, which Powerbank do you suggest? 10000 mAh Li-Polymer is okay? And is there any risk using it as permanent option? I mean if we connect it between power source and router for longer times? Please clarify. Thanks again for you nice video...
When you undervolt a device it may try to use the same power, which is current times voltage. As a result, there might be 2 or 3 times the current going through the wires with 5V compared to 12V. Would be good to make sure the connectors and wires are good to go for higher amperage.
thanks for the vid man was planning to buy a 5 to 12v step up cable then i came across your vid and my lte wifi modem worked fine thenks a lot :) real helpfull keep up the good work :)
Thanks seems you are in the Philippines too im in Palawan and have been trying to get something and this looks perfect. I looked into the UPS but I didnt think it would last that long. They sell on Lazada for about 1700. Ill look for this thanks!
Brilliant! So these smaller power bricks have DC outputs, which is why you were cautioning us to check the voltage? And that's why you had to change the power cord to your modem/router to a USB to DC one, right? But I found ready made ones on Amazon, like this 3.28ft USB 5V to DC 12V Converter Step Up Voltage Converter Power Cable,for Camera, Desk lamp, Speakers, Blue Tooth Headset, and Other 5V Devices.(5.5 x 2.1mm). Wouldn't this do alright, provided 5V to 12V is what was needed? They had other similar cables and end pieces to fit any size DC. One last question: If I just used my Bluetti EB3A power station with UPS, and plugged into the AC outlet on it, I would accomplish the same thing, right? (Just not as inexpensively and cleverly as you.)
Neat. I actually have such a cable laying around that I was using to power a small LCD and driver board, correct polarity and short wires on top. I tested it with with a 802.11G Linksys router I had around, seemed to fire up fine. Though, sadly it doesn't seem to work with my Motorola NVG510 DSL modem/router, even plugged into a 2Amp output power bank output. Of course, that's what I actually need to power if I want internet for my laptop during a black-out. :/
I have a question. When the powerbank is fully charged and it is still connected to the charger that is charging it, and the router is connected to the powerbank and switched on - in this scenario, does the router then end up drawing power from the current flowing in from the charger directly, and the battery in the powerbank is, well, inactive or something?
Won't this damage the router in the long run? also If it requires a certain amount of power then with lower voltage the ampage will go up, won't that potentially burn the tiny USB wires?
Mmm I dunno if I can show more than what's in this video. Cut off the end of a USB cable and connect the red wire to the positive and the black wire to the negative of the DC jack. At least if you need a center positive cable like what I showed in this video :)
Yeah for higher power routers use a usb step-up cable to get 12V output. Or better, use a powerbank with Qualcomm quick charge and buy a 12V trigger cable.
how durable do you think is the cable? and also this trick could save my life. power outages are also very common here in tondo. anyways Awesome life saving video!
You have a lot of Wifi routers O_O ive been Thinking to do this before ..but im hesitant to do so because im not sure about the voltages/amps..now that you did it and it worked..I think ill try this too..as always Great Video.
Can you confirm if all power banks that support pass though provide uninterrupted supply when main goes off ? Can you recommend brands which are uninterrupted regardless of power status changes ? I have 2 power banks xiaomi and another brand both interrupt output when main power status changes
undervolting long term could potentially cause damage, not to mention on the router it may not be able to supply enough power to fully power the WiFi antena's. Would not recommend unless you have a small area for WiFi or using cat5 only.
Your router is very low power then. Most routers tend to take about 10W, so your powerbank would have to handle 2A up and down - not every powerbank can do that. Good idea in theory and in rare practical cases, but it's not as easy as you make it seem.
How do i know if a powerbank supports pass through charging? Planning to do this. I'll most likely purchase from cdr king or miniso. Love your vids. Ta!
Excellent video !! I need this badly, I work online at home and power interruption is the last thing I need, I have a question and I hope you could help me out. How long or how many hours will it last for a PLDT fiber modem?
+Maria Leilani Ferrer I've never measured the power usage of a Fiber modem/router so I'm not sure. It would also depend on the size of your powerbank and whether it's a genuine capacity powerbank.
I see thank, you G.A. I hope you could find time to demo a power bank for pldt fibr it has 2.5A you are going to save a lot of online home based workers save their money and keep their jobs.

Hi. Nice video. Is there any way (or any circuit) to make a 'by-pass thing' to avoid the powerbank to function 24/7 and only work when power is off?.
Really helpful video. I want to try this for my modem as well as cardless phone. What happens if i swap positive and negative by mistake? will it damage my modem or it simply does not boot until i connect it correctly? Please advise. I do not want to loose my modem.
I'm glad you like it :) You can find a pre-made cable on Amazon and eBay by searching '2.1mm USB cable'. Here's an example on Amazon UK - www.amazon.co.uk/GA/dp/B00SCBAE00
Great video, Thank You!! One question: Is there an easy way to spot this passthrough charge capable power banks? I've checked a few, I could not see this listed as a feature yet... I'll keep lookin..
The reason the 5v in 12v router works is a lot of routers actually run internally at 5 or 3.3 volts and use some kind of simple voltage regulator to bring the 12v down. However, you may see some stability issues if the provided power is not quite sufficient, wifi radios are power hungry and may make the power bank's output sag.
Indeed :) So far I've not seen any problem operating the basic ISP provided modem/router combos, even under reasonable wifi load. Even my $2 powerbank seems to manage it okay. Although personally I'm using a good quality powerbank with 2A output to replace the lead-acid battery UPS that I showed in this video.
hi, does all moyou brand supports pass through power? What model did you used on this video? Is it safe to plug it 24/7? I would like to use this to power my raspberry pi. Hope you can give me some insight.
Yep it's really nice to have a pocket wifi backup. But then most people have a data cap on their mobile internet, so they might still prefer to get their landline internet working instead.
How does it work in the long term? Does it affect the functionalities of the router in, say, a few months or a year? I mean there must be a reason the routers say 12 V, isn't it?
in the description box, he said, -"During a power outage, you can manually swap from the AC power supply to your USB powerbank supply- or _you can buy a powerbank which supports pass through charging and leave it permantly attached to an AC USB charger._ " I guess there are power banks that can be plugged on the power outlet and pass it on to the wifi modem. (?)
hey bro nice video but i have a small problem is when u connect both port in and out simultaneously there is any battery problem beacuse when batterys are charging it is not gud to use simultaneously please help me out from this problem thanks..
Wouldn't the constant charging destroy the power bank since it has 500 charge cycles or does the USB wall charge does a trickle charge? Also how would one look for a pass trough charging I have a idea or a solar panel that charges a power bank that charges a rechargeable light
It depends on your powerbank. Some support pass through charging where the power from your AC supply bypasses the battery cells and goes straight into whatever you have connected to the powerbank. Of course it will still need to trickle charge the cells now and then to keep them topped up. The specs listed on the sales page usually indicate if this is possible.
Gadget Addict so pretty much the 500 charge cycles won't be affected? Or the life span of a power bank doing this for a "fail safe" in case of power outage?
A charge cycle is a full discharge and recharge. Most of the time it will stay trickle charged from the AC. Provided you buy an appropriate powerbank, there should be no longevity issue.
I have a Mini DC UPS. But the manual is clearly translated from another language and not very helpful. 1) Do I leave the Mini DC UPS plugged in with its power cable? 2) Do I keep the Mini DC UPS powered on at all times? Struggling with constant loadshedding.4
Hi, I want to use your router/powerbank trick but I dont know how to check the polarity so that I can connect the right wires. I only have a clamp meter 266 and I have already severed the wire of the adapter. Can you help me identify which is the load wire and which one is earth/neutral?
Unfortunately doest work on BT Hub 5 router or their Openreach modem :( ordered a RAVPower 27000mAh power bank with built in 220V AC Outlet, hopefully that'll work but it's costing me £180 :/
Did you try with a very short USB cable? I've found some routers only work with a 1-inch cable because of the voltage drop. And even then I had to use a cable with thick wires inside. Of course the other alternative is to buy a 5V to 12V USB cable which can be had for a few pounds and is generally much more reliable. The Rav will do the job, albeit at a higher price.
Weird, those numbers don't quite add up. 12V at 1.4A is 17W and 5V 2.4A is 12W. And I'm amazed to hear your BT router is consuming that much power.. incredible.
You said the output was 12V 1.4A and the input was 5V 2.4A. So that's 12W input with a 17W output. Many routers state a certain power input but often use much less. For example the one supplied by my ISP claims 12V 1A which is 12W but it actually consumes 3-4W.
yup i actually used a laptop battery 10 volts to power our internet modem 12v..& it works.. but the problem is our internet provider server no electricity too... useless & i dont know why they dont have a back up power.. very dissapointing..

Cool video to show off your power bank and router collection. Nice idea. I have my router on a UPS and the lead acid battery seems to be dead now so would need this alternative.
been doing this for almost 2yrs. and it really works on my globe/prolink router
Thanks for sharing that :) I've had it going for just a couple of days but the principle is solid so I'm not surprised to hear it going for years :)
Gadget Addict i have 5 power bank, i use 1 dedicated to my router
john doe YOOBAO 10000MAH, napansin ko pag asus or mi powerbank gamit ko di stable ung internet
you always have the nicest gadget (referring to usb watt meter 'cause I've been looking for a decent one for a long time) anw. where did you get or what do you exactly call that round adaptor? I'm definitely going to make this project. thanks for sharing this.
You can find the little connector by searching 'DC Barrel Jack terminal'. I can't remember where that specific watt meter came from. I think it's from eBay. The portapow advanced meter is still my fave.
I think your video is awesome.
I have a Lenovo pa10400 power bank and I am able to charge and discharge it simultaneously. However I want to be sure if it is actually pass through charger or is it just taking power from the battery and powering the router and then the power bank charging it self when the battery drops below 100. Pass through charging should simply connect the power input to the out of the power bank unit if the power bank itself is fully charged. If this doesn't happen then it will simply keep consuming battery cycles of the power bank as it will keep charging as soon as it drops below 100. Would like your views on this.
Hello,
Very interesting idea/solution. One question to check, which Powerbank do you suggest? 10000 mAh Li-Polymer is okay? And is there any risk using it as permanent option? I mean if we connect it between power source and router for longer times? Please clarify.
Thanks again for you nice video...
hello, nice informative video. :) I would also like to know if its bad for powerbank to use passtrough to power a device 24/7 ?
100% works. Thanks a lot bro making this video. Really useful 10 out of 10. Hats off to u❤️❤️❤️❤️❤️❤️❤️❤️
Hi please i need a recommendation of a pass through power bank,
Which one are you using thanks.
How about a link to buy the Moyou.
When you undervolt a device it may try to use the same power, which is current times voltage. As a result, there might be 2 or 3 times the current going through the wires with 5V compared to 12V. Would be good to make sure the connectors and wires are good to go for higher amperage.
thanks for the vid man was planning to buy a 5 to 12v step up cable then i came across your vid and my lte wifi modem worked fine
thenks a lot :) real helpfull keep up the good work :)
Thanks seems you are in the Philippines too im in Palawan and have been trying to get something and this looks perfect. I looked into the UPS but I didnt think it would last that long. They sell on Lazada for about 1700. Ill look for this thanks!
Mat, you are just bloody easier then every one. Thank you
Brilliant! So these smaller power bricks have DC outputs, which is why you were cautioning us to check the voltage? And that's why you had to change the power cord to your modem/router to a USB to DC one, right? But I found ready made ones on Amazon, like this 3.28ft USB 5V to DC 12V Converter Step Up Voltage Converter Power Cable,for Camera, Desk lamp, Speakers, Blue Tooth Headset, and Other 5V Devices.(5.5 x 2.1mm). Wouldn't this do alright, provided 5V to 12V is what was needed? They had other similar cables and end pieces to fit any size DC.
One last question: If I just used my Bluetti EB3A power station with UPS, and plugged into the AC outlet on it, I would accomplish the same thing, right? (Just not as inexpensively and cleverly as you.)
Phone line usually dead too 😔
Really? I've never experienced that. The telcos are required to have UPS and generators to keep those going.
long term review, did the battery pack last long? I think most of them uses the battery if the charging is not strong enough.
Neat. I actually have such a cable laying around that I was using to power a small LCD and driver board, correct polarity and short wires on top. I tested it with with a 802.11G Linksys router I had around, seemed to fire up fine. Though, sadly it doesn't seem to work with my Motorola NVG510 DSL modem/router, even plugged into a 2Amp output power bank output. Of course, that's what I actually need to power if I want internet for my laptop during a black-out. :/
I have a question. When the powerbank is fully charged and it is still connected to the charger that is charging it, and the router is connected to the powerbank and switched on - in this scenario, does the router then end up drawing power from the current flowing in from the charger directly, and the battery in the powerbank is, well, inactive or something?
Won't this damage the router in the long run?
also
If it requires a certain amount of power then with lower voltage the ampage will go up, won't that potentially burn the tiny USB wires?
no it will not damage your router has electric circute which prevent over volt and ampere and supply what router want
Was this shot in the Philippines? PLDT is a local ISP there.
Hey GA! will you make a video on how you make the cord?
Mmm I dunno if I can show more than what's in this video. Cut off the end of a USB cable and connect the red wire to the positive and the black wire to the negative of the DC jack. At least if you need a center positive cable like what I showed in this video :)
I think it works with only below 12v 1a routers not new 5g/AC dual band 12v 2a routers
Yeah for higher power routers use a usb step-up cable to get 12V output.
Or better, use a powerbank with Qualcomm quick charge and buy a 12V trigger cable.
GA great video, I can use this in Catbalogan, the Brgy on Buri Island we have brown outs a lot for 6-8 hrs, Thank for sharing.
You're welcome :) You're really having a GA binge watching session haha :D
Yes I'm catching up as your videos are awesome and very informative. :P
Buri with dead airport.. damo magdate didto paggabi na..
how durable do you think is the cable? and also this trick could save my life. power outages are also very common here in tondo. anyways Awesome life saving video!
Unless you plan to swing your router above your head like a lasso, I think it's more than durable enough :) I'm glad it's helpful for you! :)
Gadget Addict Lol. thanks!
You have a lot of Wifi routers O_O ive been Thinking to do this before ..but im hesitant to do so because im not sure about the voltages/amps..now that you did it and it worked..I think ill try this too..as always Great Video.
I accept stuff that other people are going to throw away :P You never know when they'll come in useful. I hope it works out for you :)
Can you confirm if all power banks that support pass though provide uninterrupted supply when main goes off ? Can you recommend brands which are uninterrupted regardless of power status changes ? I have 2 power banks xiaomi and another brand both interrupt output when main power status changes
Hi, 4 years later I believe you've gotten a good product.
Please i need recommendation from you as i want purchase a powerbank too
undervolting long term could potentially cause damage, not to mention on the router it may not be able to supply enough power to fully power the WiFi antena's. Would not recommend unless you have a small area for WiFi or using cat5 only.
Your router is very low power then. Most routers tend to take about 10W, so your powerbank would have to handle 2A up and down - not every powerbank can do that. Good idea in theory and in rare practical cases, but it's not as easy as you make it seem.
How do i know if a powerbank supports pass through charging? Planning to do this. I'll most likely purchase from cdr king or miniso. Love your vids. Ta!
Excellent video !! I need this badly, I work online at home and power interruption is the last thing I need, I have a question and I hope you could help me out. How long or how many hours will it last for a PLDT fiber modem?
+Maria Leilani Ferrer I've never measured the power usage of a Fiber modem/router so I'm not sure. It would also depend on the size of your powerbank and whether it's a genuine capacity powerbank.
I see thank, you G.A. I hope you could find time to demo a power bank for pldt fibr it has 2.5A you are going to save a lot of online home based workers save their money and keep their jobs.
Hi. Nice video.
Is there any way (or any circuit) to make a 'by-pass thing' to avoid the powerbank to function 24/7 and only work when power is off?.
Yeah same question here!! good video though
Really helpful video. I want to try this for my modem as well as cardless phone. What happens if i swap positive and negative by mistake? will it damage my modem or it simply does not boot until i connect it correctly? Please advise. I do not want to loose my modem.
+Kishore if you get the polarity wrong, you could damage your modem.
This is very clever Gadget Addict.Can one buy a 12v/usb cable or is it a diy cable only?TIA
I'm glad you like it :) You can find a pre-made cable on Amazon and eBay by searching '2.1mm USB cable'. Here's an example on Amazon UK - www.amazon.co.uk/GA/dp/B00SCBAE00
Awesome,thanks for the info.
Does this affect the speed of the internet
This opens my mind to a whole new level :D thanks for this info man appreciated it
Bright idea. But what if the powerbank has low mah and drain so fast
awesome Tip mate , Thanks for sharing this Knowledge
You're showing a video of already DYI but do recommend a power in the market that does the same.
You can find them on shopee, lazada, ebay, amazon etc. Just search for 12v usb cable.
power outage only a couple of hours...where I am here in Australia, 18+ hours is pretty regular :(
Great video, Thank You!!
One question: Is there an easy way to spot this passthrough charge capable power banks?
I've checked a few, I could not see this listed as a feature yet...
I'll keep lookin..
The reason the 5v in 12v router works is a lot of routers actually run internally at 5 or 3.3 volts and use some kind of simple voltage regulator to bring the 12v down.
However, you may see some stability issues if the provided power is not quite sufficient, wifi radios are power hungry and may make the power bank's output sag.
Indeed :) So far I've not seen any problem operating the basic ISP provided modem/router combos, even under reasonable wifi load. Even my $2 powerbank seems to manage it okay. Although personally I'm using a good quality powerbank with 2A output to replace the lead-acid battery UPS that I showed in this video.
Damn that's lot of powerbanks
Brilliant.
Thank you so much for this.
Simple and effective.
hi, does all moyou brand supports pass through power? What model did you used on this video? Is it safe to plug it 24/7? I would like to use this to power my raspberry pi. Hope you can give me some insight.
Thats why I prefer sim based internet plan. I can just put it in my pocket wifi when there is no electricity or take along with me when i travel
Yep it's really nice to have a pocket wifi backup. But then most people have a data cap on their mobile internet, so they might still prefer to get their landline internet working instead.
yeah, my plan only have 150Gb data
joy santod haha i cant live with a data cap, i use that much in two days
How does it work in the long term? Does it affect the functionalities of the router in, say, a few months or a year? I mean there must be a reason the routers say 12 V, isn't it?
Where the heck did you get that Neon green USB charger? It's like it's screaming at my face "I'M HERE!!!"
Kuya, what powerbank brand is the best for wifi modem? Any suggestion?..thanks.
Great video, can you leave the power bank permanently plugged in to the router and also into the power supply (wall socket)?
Did you get an answer on this?
in the description box, he said, -"During a power outage, you can manually swap from the AC power supply to your USB powerbank supply- or _you can buy a powerbank which supports pass through charging and leave it permantly attached to an AC USB charger._ "
I guess there are power banks that can be plugged on the power outlet and pass it on to the wifi modem. (?)
I have a 12v Huawei Fibre router with a USB to DC cable running from my powerbank, but it does NOT work like in your video. Any suggestions???
hi, I have a question.
How many hours you think that powerbank can supply a router? 3 or 4 hours?
Wow. How much mAh is that powerbank you're using?
hey bro nice video but i have a small problem is when u connect both port in and out simultaneously there is any battery problem beacuse when batterys are charging it is not gud to use simultaneously please help me out from this problem thanks..
Wouldn't the constant charging destroy the power bank since it has 500 charge cycles or does the USB wall charge does a trickle charge? Also how would one look for a pass trough charging I have a idea or a solar panel that charges a power bank that charges a rechargeable light
It depends on your powerbank. Some support pass through charging where the power from your AC supply bypasses the battery cells and goes straight into whatever you have connected to the powerbank. Of course it will still need to trickle charge the cells now and then to keep them topped up. The specs listed on the sales page usually indicate if this is possible.
Gadget Addict so pretty much the 500 charge cycles won't be affected? Or the life span of a power bank doing this for a "fail safe" in case of power outage?
A charge cycle is a full discharge and recharge. Most of the time it will stay trickle charged from the AC. Provided you buy an appropriate powerbank, there should be no longevity issue.
Gadget Addict hmmm now to find a cheap pass trough charging power bank
Works but only the modem turned on but it won't connect to the ips provider i think 5v is not enough to connect to the internet
How much time would a 10amp powerbank will keep the router going?
I have power bank, Which is better for Fiber Optic router 12v or 24v power supply ❓
I have this for long years, but in my village if I haven't power in house, also I haven't internet connection.
What is that adapter called? I'm planning to buy one.. do you think Ace hardware have those?
*Is there a way to know if a power bank support pass through power?*
So, can this be used as a long term solution? If any, what component of the setup needs replacing?
I have a Mini DC UPS. But the manual is clearly translated from another language and not very helpful. 1) Do I leave the Mini DC UPS plugged in with its power cable? 2) Do I keep the Mini DC UPS powered on at all times? Struggling with constant loadshedding.4
Are there any safety issues here? Ie. Leaving it plugged in with pass through on charge?
You can go undervolt but the signal will be weaker
Hi, I want to use your router/powerbank trick but I dont know how to check the polarity so that I can connect the right wires. I only have a clamp meter 266 and I have already severed the wire of the adapter. Can you help me identify which is the load wire and which one is earth/neutral?
And at the process, save up for a dedicated UPS. Saves my as* a couple of times.
Unfortunately doest work on BT Hub 5 router or their Openreach modem :( ordered a RAVPower 27000mAh power bank with built in 220V AC Outlet, hopefully that'll work but it's costing me £180 :/
Did you try with a very short USB cable? I've found some routers only work with a 1-inch cable because of the voltage drop. And even then I had to use a cable with thick wires inside. Of course the other alternative is to buy a 5V to 12V USB cable which can be had for a few pounds and is generally much more reliable. The Rav will do the job, albeit at a higher price.
Gadget Addict I bought a USB 5v - 12v cable of Amazon, I tested the output with my multimeter and the outup was 12v but only 1.4 amps. Input 2.4 amps.
Weird, those numbers don't quite add up. 12V at 1.4A is 17W and 5V 2.4A is 12W. And I'm amazed to hear your BT router is consuming that much power.. incredible.
Why does it not add up? The plug says 12V=1500mA, the router is meant to be 9.2W.
You said the output was 12V 1.4A and the input was 5V 2.4A. So that's 12W input with a 17W output. Many routers state a certain power input but often use much less. For example the one supplied by my ISP claims 12V 1A which is 12W but it actually consumes 3-4W.
Hello , Great Video I Just wanted to know that what power bank do u recommend me for my ADsl+Wireless router ?
Any with a 5V 2A output :)
Thanks
there must be a reason why these routers are rated as 12V and not 5V
have you tried this method with a router using all the Lan ports?
Where did you buy that thing at the other end of the USB cable?
i dont think you need too proove soo much you haveallready done enought thanks again
can i use my One power bank 5v
use my two router 9v and 12v together?
There is 2 units, 1 router and 1 for wifi. Do I need 2 usb cord to connect it with my powerbank?
This is a life saver. Thank your for this.
thanks for sharing knowledge. Now I know about it.
yup i actually used a laptop battery 10 volts to power our internet modem 12v..& it works.. but the problem is our internet provider server no electricity too... useless & i dont know why they dont have a back up power.. very dissapointing..
Power rating of my Router is 12V - 2.5 A. Question is can i plug it to a USB with an output of 12V but only 1.5A? Thanks.
