Julian, you are blessed with a good memory - all those different charging protocols, and more, and more, and more.
Please go for it! Julian.
Would love a video on the diy mosfet drivers. Need something like this. Thanks Julian.
The QC3.0 protocol can can supposedly max 20v @ 1.5A = 30w total power in 200mv increments as negotiated by the device being charged. However you need to have the input voltage higher than 20v on the input on that charger. It's a buck only charger.
Did you test with input voltage of more than 24v since this is a step down converter?
Are you ever going to change your Lead-Acids with LiFePo's?
That's quite an investment for little gain.
Not really, I used to use a bunch of lead acids and they died after a couple of years of heavy cyclic use (e.g. running a raspberry pi 24/7, charging my phone, headphones, bike-computer etc overnight and running my notebook) whereas my lifepo's have held up much better at a similar usable capacity. Also the charge/discharge efficiency is just so much higher than lead-acid. A 20Ah/265Wh Lifepo can easily replace a 50-60Ah Lead acid bank whilst having a smaller footprint and a much longer lifetime (up to 40+ Years if you don't go over 1C and 80% DoD). The benefits with lithium outweigh the cost by a lot.
If you buy a new one, yes, but replacing an existing one before it's dead is another matter.
I wish companies would have a charge limit function, so I can have it stop charging at 80% or whatever it set it to.
I would love to see this. Similar thing as the Tesla etc. electric cars have, don't charge or discharge the battery all the way to get more lifetime.
Surely there's an app for that :)
Perhaps, but try searching for it... 786 apps which will claim to charge your phone 5X faster is what you will find. And lose the will to live any longer on this planet.
Edit: f-droid seems to maybe do it but you need to be root of course.
I had a Sony Vaio Laptop that had this option! I used it but it didn't help cause they used Samsung cells...
Moto-mod batteries have that feature. My phone battery stays at 80% until the mod is empty. But the mod battery charges to 100
Hi Julian, any chance you could talk about the perennial problem of radio interference produced by usb chargers in the car. What causes it? Can it be suppressed?
I cannot get this thing to power up using my guitar pedalboard power (Truetone CS6). I've got 12Vdc with 1600mA max output on the board. Works fine with a 12V battery but it doesn't get any power from my pedal board power.
2 QUESTIONS: Do Buck Converters create "noise" if used with a 12 volt battery to output 5 volts to a portable radio receiver? Is there a way to eliminate the noise? Thanks
So stupidly awesome! There are so many things to learn from USB that it is a profession in itself! I'm confident it will be a part of my job one day!
The LEDs come across pretty bright on screen, are they just as dazzlingly bright in person?
SMD LEDs always look bright. I think it's because the light source is so tiny and there's no lens.
poor blue LEDs when in 12V mode :)
Hello there. For D3806. rx tx pin. for arduino. reference? guide? sample? explanation? to inform? could you send?
Hi there, I was impressed with this video that i had bought me a handful of these Modules. but apon testing these with my Samsung that has the quick charge features. this module still appeared to charge at a slower rate than my plug in charger. I see that you used tools to test the modules, but what about devices? have you actually tested any of them yet ? i have the TAB E Tablet by SAMSUNG, and my friends have Samsung phones as well. can you tell more on what devices this will FAST CHARGE ?
Thanks.
Should this not have USB C ports on it???
What is the ripple voltage in these?
What is the name of that module?
Hi Julian! Any plans to check out USB-C PD (Power Delivery) devices? PD can negotiate up to 20V*3A between devices. I think a PD Power bank and buck/boost would make a very neat portable power supply.
When such a device ends up on my desk - I will inevitably look at it. Maybe the next gen soldering iron will use USB-C PD at the maximum 20V * 5A = 100W. But I don't think the TS-80 will do that :)
If this can go up to 20 volts and it's a buck converter how can it go above the input at 13.6v?
By changing the solar system to a 24V system
you could always use a boost converter before the buck too.
It's not efficient, you have losses of two DC2DC converter units in one system. So you take a higher voltage system and step it down instead of doing up/down acrobatics.
Kyôdai Ken+ It's not efficient, but it's a lot more convenient to use this method for a 11 minute video than upgrading your entire solar system to 24v for that 11 minute video because he already has the boost converter and as he said before for use on a gimmick, he looks at it like free energy anyway so you tell me which one is practical being that quick charge will most likely wind up in a junk drawer or bin to never be seen again because they're in most every car or has them built in or in a lighter socket which boost the voltage from 12 to 24v anyway or all of the phone chargers plugged in all over the house wherever I go we all have access to. That's how I'd look at and most others when the system you're using works great for your videos and gets the job done.
What USB monitor is that in the video. Model number ?
He told you the model number in the video itself: UM24C.
Thanks, missed it. Model number is on the display, should have googled it.
Since I'm not homeless, where I sleep there is electricity. My phone can have its daily recharge while I sleep. It's got at least 7 hours.
I suppose there must be some people using their phone so much that they need to recharge on the run, several times per day. For them, I'd prescribe a portable battery pack. That way they could keep running.
When I eventually get an electric car, that's where fast recharging would be essential. Because I'd rather not sleep in a recharging station halfway to wherever. At home, we're back to overnight again.
Even without being homeless there's plenty of times you need a battery bank - if you travel especially by air you can end up going more than a normal day without someplace to plug in. Also, in case of storms and power outages you won't have someplace to plug in your phone to charge from mains.
That's another problem with electric cars - when a storm hits you may lose power, then you can't charge. Or if evacuating, you may not have the option to stop for 12-16 hours and camp at a charger because of storm arrival, power outages, or everyone else also needing power. That's where gas cars have the advantage - a gas station can run their pumps on a fairly small generator to pump gas and you can stockpile a few 10 gallon cans for emergencies (and you probably have them already for lawnmowers and other yard equipment) - in an evacuation you could strap them to your car and have an extra few hundred miles of fuel on hand. You can't do that with electric cars.
Hi Julian, I wonder if you would be so kind as to giving me a bit of guidance...RE CHARGING.
I intend to use x2 (11.1v-12.6v) cells to power my device, and the intention is to have some solar panels onboard to maintain charging of the batt cells. Can you tell me if you think this ebay item (282794969168) would be a suitable fit for this job, I would want to minimise the current and the voltage to protect against over charging. The item is describe as a 4A rating, my batteries would each be between 2000mah & 3000mah (parallel). much appreciated julian, keep up the great work :-)
If anyone else has any info on this subject. please feel free to reply. Thanks
I must be one of the few people who don't like charging their phone fast.
My phone supports fast charge, its a Samsung Galaxy, but I use a usb cable with no data connections to force my phone to charge slowly, it still charges in only a couple of hours so I charge it in the evening when I am at home watching TV so it does not matter if it is slow, and hopefully I will get the maximum life out of its battery.
It's indeed better to charge slowly for the battery life. But it's also really convenient to have to option to fast charge when you are in a hurry.
Yeah, this whole rapid charge thing worries me - on both phones and electric cars - there's always a downside - battery temperature (and therefore battery life) is the tradeoff.
i think that charging your phone with fast charging doesnt hurt it as much as leaving it into a normal charger for whole night
@EI - You do realize that when the battery reaches 100%, the phone stops recharging the battery. Right? It's not as if the charger and phone are beating away on the battery all night.
Acknowledge in advance that if you float the battery at about 50% charge, it'll last much longer (meaning years of lifetime). But that's not a practical option for most people.
Let's not forget that Quick Charge is really badly named. All that QC does is to increase the voltage to try to get round the losses due to the resistance of the cable and the connectors.
I'm not really a fan of those blue terminals, I like the elevator type more. Makes a more secure connection. What is the point of good circuit design if you have shit connectors feeding it.
I only use Phoenix Contact brand name terminals from reputable suppliers.
I hope I'm just confused. You're going to use a buck/boost coverter connected to your 13.8v solar panel supply - to provide a 12v output to power a USB soldering iron? That's crazy! Julian, please... just put a couple old diodes in series with the 13.8v and call it a day. Then again, if you use enough of those '5.1mm coaxial - to - 2 pin' adapters.. you won't even need diodes. You'll drop enough energy in those connections ;-}
Those diodes would be 5-6 watts of waste heat generated all the time... and still the iron voltage would vary with the battery voltage. not very nice (but perhaps awfully fitting for this particular channel) ;-)
haha, yeah. my only defense? in the mid-west, in the winter time - those hot diodes will only be adding free heat to the homestead dwelling - making Julian happy, relaxed, and in the mood to come up with new odd concoctions ~{:-]
Can of worms in deed, USB was supposed to be one standard. Infuriating.
Whats next, USB stick welders? just plop an electrode into it and you get 100V and 100A?
Puts 12 volts out on 5-volt jack. That sounds dangerous.
It isn't. Cause it needs to be negotiated, and only devices capable of 12V will get 12V.
Read the Quick Charge 3.0 spec. You have Google. And it's not a 5V jack.... it's a USB jack.
that usb jack won't put out 12v, unless the connected device requests it. nothing dangerous, unless someone messes up data lines..
put a couple of fuses to protect from the board would draw me to it. Thanks for sharing, I enjoy your vids
That RuiDeng meter can actually show the charging mode. You were at that screen when you plugged it in (notice the "unknown" indicator) but you switched to the wrong screen afterwards. It is always good to read the instructions and know the device you are using.
These modules are not compatible with Samsungs Fast Adaptive charging mode. Why not ? Can I modify somehow so that it would work ?
Julian, Test QC4.0 chargers next-
great potential 100W fast charging.
The numbers game is really getting out of hand, like it usually does with these things. "Bigger number? Must be better then!!" mentality with complete disregard of what's actually reasonable.
The only reasonable thing is a 20 Ah battery in phones, making them thicker and heavier. But no, people fall over if the phone weighs more than 100 grams...
Um, 100W is perfectly reasonable, actually. USB isn't just used for charging phones, y'know?
QC4 is compatible with USB Power Delivery, and they're largely the same: each goes up to about 5A at 20V = 100W. No, 100W isn't really practical for phones (yet, anyway), but it's super useful for other things. We're already seeing Apple (and probably others by now) using USB PD to charge laptops; Nintendo uses USB PD to charge & power the Switch; Miniware could use USB PD to bring out a USB-powered soldering iron like the TS-80/100, but rated up to 100W - how about that for a portable soldering iron?!
Is something possible with a usb-c input and 2 usb-c outputs?
you did not test the max current it can output and also how hot it gets etc.
Hey Julian- You are obviously far more knowledgeable than I am in this entire subject, so I ask: Re: Reducing phone battery life, doesn't raising the voltage and lowering the amperage for "quick charge" reduce the heat and prolong battery life? Or am I way off with this?
would like to see more usb pd instead of qc
4:47 Buying links for these 3 usb modules which can trigger QC? especially interested in these two red ones.. i wonder if i could make it stay at 12v for example, is there anything that can do that? Please help me out
I look forward to your TS80 review and thoughts
might want to try the Ruideng LD35 which is an electronic load with QC triggers.
That sounds like fun :)
Julian, Can you do the kit build of the LED Light Bulb?
Is that the one I bought years ago?
Yes!
Can You Build It?
No load test?
Both power banks presented a load to the converter :)
The quick charge system us so cool and ive been a massive fan ever since i figure out what it was when i had my Samsung s6 when it first showed up
It's immediately out of USB spec. 5.34 V is more than 5.25 V that standard specifies.
Doesn't hurt anything. It's needed to compensate for the extremely shitty UAB-A sockets and plugs, they have very high contact resistance. The device still won't even see 5V...
IMHO using USB (any type) as a power distribution system is madness. Crappy connectors that are not very good at handling high currents. Crappy thin cables. Mini and micro USB connectors are even worse.
Give me a D-connector or XLR connector which both can handle 5A per pin :-) Where only power is needed, a 2.1mm barrel ‘DC’ power connector. Or if space is an issue, a 2.54mm spacing three pin connector (middle pin being the positive 12V, the other two both being 0V, so reversing it does not matter).

Especially the arc extinguishing capabilities of USB, or rather the lack thereof. Even with modern USB-C Connectors I wouldn't want to be hot-unplugging a connector that has 100W at 20V (5A) running through it without first switching some mosfet to un-load the connector.
Shows how little knowledge people actually have about this technology...
the TS80 only takes 9V
Disappointed that the TS80 does not do USB-PD. Even Google is recommending PD for the newer Android devices... but yes, QC is quite common here in China as almost every phone and powerbank supports this. Note: the TS80 does not have the CC lines connected to even support PD, so an external solution is recommended.
Oh, I'm really hoping the TS-80 will ask for 12V. Banggood's listing shows 5V/9V and 12V in the specifications :)
Julian Ilett I have the ts 80 and can only get it to work at 9v...but still a great handy iron for me to use on site with my power bank
Found out why Banggood wrote that description as you mentioned. These are the specifications of the included DN.OX branded Quick Charger 3.0, model: DNQ18U-U.
The TS-80 only asks for 9V in its stock firmware, yes. However the internals of the iron are rated up to about 16V (as per this comment by the creator of the third-party TS-100 firmware, which he's now made compatible with the TS-80: github.com/Ralim/ts100/issues/349#issuecomment-417179746) so it could be possible to get the third-party firmware to request 12V. That same thread says that, while USB PD straight from the iron isn't possible (the "CC" lines of the USB-C port aren't connected to the microcontroller), it should be easy enough to use external inline modules to negotiate 12V from USB PD and feed that straight into the iron's USB-C port.
Regardless, I *highly* recommend you flash Ralim's third-party TS100/80 firmware, because the stock firmware is extremely fussy with voltages. I have three QC3 supplies (I had a fourth - the one that came with the TS-80 - but it's already died on me! It's actually REALLY well-designed and well-made inside, so I'm not quite sure why it's died, and my probing hasn't yet located what's failed...) and on two of them the iron would complain of "low-voltage" (technically it shows "LOW-VOT"...) and shut off when it started heating and the 2A current draw would cause so much voltage drop along the cable that the voltage measured by the iron would drop below 8V :( Ralim's firmware, on the other hand, doesn't have a lower voltage limit (it'll even heat from 5V if you really want to!), so it'll happily work from anything.
