What might be more useful for actual purposes is just the 1st part, as most low power stuff runs off DC internally anyway. If the LED lamp has a proper driver in it and not just a capacitive dropper, then you can run it from 100V DC easily.
This is very Useful. Thanks for sharing , Let me share a usecase of it. In the areas where there is a power cut and that too for a very short duration let us say one or two minutes ( by the time Generator is turned On) . It can be used to Avoid the restart of Broadband modem as UPS are little expensive. With a little modification where it acts as a UPS ( just to avoid the Restart of Model for 2 3 minutes ) will be of great benefit .
Finally! I've been looking every where for this and asked at Best Buy and they said that was a rare request and didn't have anything for this. Why isn't it more common since power banks are often usb and many other things are still AC.
awesome video. That's good when there is a brown out and use for emergencies. Can you please list the parts needed to do this. Thank you for sharing this with us subscribers.
If there was a way for you to activate QC 3.0, you could actually get 18W out of that port. Also, I know this violates USB standars, but you could wire both USB-A ports for 30W of power. Although you'll only get 30W/24W depending if you activate QuickCharge 3.0 or not.
yes it's possible but another limitation would be the current.. you just excuted dc to ac experiment we have that in college but not using power banks because its not available tha time. we used then 555 ic or zener diode rectified circuit which in turn outputs a 5 volts. like that power bank
I completed your experiment,it works but not perfect,Like you said from 2.1ahm USB output of old PowerBank not the PD option.i ordered the components on Lazada and Shoppe it cost me ₱600 more because I ordered in more than 1,if you order only 1 shipping cost will charge you,So by 2pcs. or 3pcs.i found 2 errors or flo on the project.For those who interest in building this project I will let you figure it out.because I spend a lot to know how it ticks. I will try the Latest PowerBank feature the PD power delivery to tiny inverter,But not today FEB 25, 2024,Maybe in a few months.Latest PowerBank are not cheap to buy.And I will compare witch is better.i wish I can learn to Vlog to show the experiment well
What about stability on volt and current?Did the Boost converter is overheating?Cause it absorbs pressure from Load? I'll copy your experiment once the electronic components arrive from Shoppe,This will be Fun if it's turns out alright.And I'll comment again if stability becames issue and how will I resolved it
Hi 👋 Awesome channel keep up the good work. I wanted to ask if it were possible to connect the three USB ports together in parallel to increase the current without burning the house down 😂 ??? I’m using the Anker 26800 mAh bank. Also is it possible to safely tie multiple battery banks outputs together ??? I’m trying to use a Duracell 175W inverter using the bank/banks.
Hey, great, I'm currently *exactly* on that very same "trip" of combining multiple cheap 57k mAh power banks (30$) to get to at least 100 to 200 W, so I found this video and your brilliant comment! 😻 Surprising that nobody caught up on this, because only then all this starts to really make sense and being useful. Thanks for the input of using multiple ports of each unit, I hadn't thought about that one so far, but might test, in case I should really go for this setup, but I think I'm insane enough, yeah! ✊🏻 😹💦 I found many USB 5V to 12V adapters/cables, so I would assume I just get a bunch of these, cut the 12V end open and hook them up in parallel to a car charger inverter via a car charger plug to raise amp/wattage. Does this sound sane?! I'm still such a noob when it comes to such stuff! hahaha
Great video (as usual), but I have a question... I have literally hundreds and hundreds of 18650's from gently used laptop batteries from my work. My problem is, I'm terrified to use them in an application like this. Throw a rock and you will hit someone with their masters in electrical engineering and 30 years experience, who will tell you that 18650's (or Li-ion in general) are very unsafe as far as batteries go. Unlike a Tesla, where you have 7,000 that are chemically matched and charge-balanced, how else would someone make use of hundreds of mismatched cells? (And please forgive my ignorance, I'm a cloud-engineer and a musician, hence the dumbness). Thanks as always!
There are many people who've made DIY Powerwalls using 18650s from various brands. They just capacity test them all to try find those which closely match in that regard. Provided you're using fuse wire in your pack, balance leads and a proper BMS, I don't think you'll have any problem. You might want to check out the TH-cam channel ' nocrf50here ' - he's one of the kings of 18650s on TH-cam and has done many experiments that cover your exact question :)
I need a backup battery pack for my electric recliner for electricity outages. Do you know if this would be strong enough? Could I hook this to the DC electricity and when there is an outage it will work to close the recliner? Thanks, if you know the answers :)
please provide 5vdc to 12v ac convertor and 12v to 240v inventor link, i search on google there are plenty of them and get confused 😕 which one to order.
Sorry if this is a dumb question but do you know if ac powered appliances ca be converted to be charged up via usb cable. I’m a carpenter by trade so this is very much a novice shooting in the dark. I’m guessing would be much easier with battery powered to usb
The thing with power tools is that they often use a lot of power, especially when the motor first starts to spin. You're unlikely to be able to power many tools by USB, especially if they're designed to run on AC. If it's battery powered, you'd have a better chance, but still probably not by USB. Just with a DIY high-output lithium pack. Or a jump start pack.
tried this after watching your video. didn't work out as planned. A red fault light turns up on the inverter although i use that same intveter in my car for Charing laptop and it works perfectly there
It's possible that your DC to AC inverter is drawing too much power. Some inverters consume as much as 10 watts when idle. A typical USB port can only output 10-13 Watts.
+John Aquino well there's not much to discover tbh. There's plenty of DC-DC converters and 12V DC to 220V AC inverters out there. I just took off the shelf parts and put them together.
interesting idea,so I just need to buy and connect a DC to DC converter bring up to 12v and I just connect to a car power inverter and I can have tiny generator for small led light bulb for a small room :)
wow. amazing little device. why does the volts read 400++ with no load. i get a funny hz reading on an old generator i used to have reads like 300++hz and keeps increasing. can u tell me why mate?
Cheap basic electronics, it doesn't have much on there to regulate it. Fun for experiments but not overly practical by itself. As for the rising hz, not sure about that. I've never seen anything like that before.
i didnt have anything to test/break so i ended up tossing it in the bin less the engine. shame really. but every repair shop i took it to wanted the cost of a new one to repair it.
It would likely struggle. The better option would be to buy a powerbank designed as a car starter. They typically have an unregulated 12V output which you could connect a DC-AC inverter to.
This specific setup can only output a low current, so even if you did try to charge a laptop, it would be extremely slow. Since most laptops charge at 14-19V, you'd probably have better luck using a 5V boost converter (DC-DC). Or buy a PD powerbank and a PD trigger which allows you to select a specific voltage to charge the laptop :)

Ravpower sell power banks with AC outlet on amazon :).Anker also sell one.
This is great! I've been trying to figure out how to make our UV lamp portable. Thank you and stay safe!
I'm trying to do the same. Have you tried this and does it work for you?
I wonder if there is a way to combine 3 5v battery banks in series. That would give us 15v and should easily run an inverter, albeit not a big one.
awesome video. That's good when there is a brown out and use for emergencies. Can you please list the parts needed to do this. Thank you for sharing this with us subscribers.
can you link the parts you have in ebay

+NeutronPCXT I was hoping to find a little pass through device that could activate QC on the port but no luck so far.
Measure the frequency of the 240v out if able...
yes it's possible but another limitation would be the current.. you just excuted dc to ac experiment we have that in college but not using power banks because its not available tha time. we used then 555 ic or zener diode rectified circuit which in turn outputs a 5 volts. like that power bank
good job gadget addict for the education and propagation of knowledge

Is this the PD option of the latest PowerBank?Power Delivery (PD)? Or the old version 2.1ahm output USB.
Please, can you link this piece, because I searched a lot on ebay and other sites, but I did not find it. I hope you will help me find it
What about stability on volt and current?Did the Boost converter is overheating?Cause it absorbs pressure from Load?

can you run tv from this piser bank by this way also, let me know the time also please ?
Link to buy materials from eBay? :)

Could you please maybe put up ebay links?
I bet that would be handy in charging a turned off laptop.
how many hours I can use this for a laptop if its 30000mh powerbank
This is exactly what I needed thanks
please try the 220V AC from CD-R King PowerBank
Is there one I can buy that is ready to use?

Why not try running an old game console with low wat consuption off of the power bank with this contraption?
I need a backup battery pack for my electric recliner for electricity outages. Do you know if this would be strong enough? Could I hook this to the DC electricity and when there is an outage it will work to close the recliner?
Thanks, if you know the answers :)
Can you tell me the brand and model of your recliner? Or check if there's a sticker that says something about voltage, current or wattage.

I wonder...
What if I buy 5V USB-A to 12V car charger
Then using car charger to 220V outlet
Can i switch the wire upside down like live and neutral switch to live wire touch neutral pin and neutral wire touch live pin in a uk plug
Its not the powerbank its the inverter board ints only 35w and your trying to powrr a 65 its very obvious that it wont turn on
sir,please give link to buy 5v to 12v converter
Search for 'usb booster converter' on ebay and you'll find many options :)
may I ask how many mAh is your powerbank
how good of a zapper is that? will it give me a nice shock mate or will it cutout
It likely has the potential to kill you.
wow. amazing little device. why does the volts read 400++ with no load. i get a funny hz reading on an old generator i used to have reads like 300++hz and keeps increasing. can u tell me why mate?

That's the problem with trying to repair things now days, it costs more than a new one with fresh warranty :(
I want to have just like that
saan nyo po nakita ang inverter
ok thank you
Can it work on a small fan and other things that are rated 220V
It would likely struggle. The better option would be to buy a powerbank designed as a car starter. They typically have an unregulated 12V output which you could connect a DC-AC inverter to.
We can charge laptop using this ?

saan nyo po nabili yan
sir,i cannot find any 5v to 12v converter
Just go on ebay and search for 'usb boost converter'. I just tried it and found many.
sell me. price?
can i plug my ultrabook laptop to charge it? thanks!
nice info. i want this product. need this to plug to any usb port so my wife could plug her breast pump... plis let me know
Let you know what? :)
450v AC USB KILLER PLUG IT IN A COMPUTER AND SEE WHAT HAPPENS
Lot of power wasted in this method. Why not use 5volts led with usb cable and directly connect to power bank. Not morethan half a amp will use.
+Roman Asidera it's not about lighting a bulb. It's about getting high voltage AC from a USB powerbank. The bulb was simply a sample load.
And you can build 18650 battery power pack that can power small ac appliance like light bulb 220v.
lol , u dont get the purpose of this experiment bro
