Playing with USB Power Delivery

[@JulianIlett]

Awesome video - that little trigger board is excellent - cheers Adam :)

[@AdamWelchUK]

It’s pretty neat isn’t it? Cheers Julian.

[@RWBHere]

That's a very useful little board. At a pinch it can even double as a laptop PSU, with 19 Volts at around 3 Amps, and only rising to 20V off-load. Thanks Adam.

[@JackButlerVideos]

Great video! I love playing with USB-PD and QC3.0 it's so interesting! i used a similar car socket like that for my solar bike to charge my laptop with USB-PD. i would be interested to know if you set the trigger board to 12v or 20v and unplug the USB C connector it remembers the last setting? it could be handy if you were going to use it more permanently in a project! Cheers!

I just purchased a power bank that has a rated pd output of 80w im looking forward to testing that with one of these boards

[@cameraman1234567890]

What about a trigger board that remembers its setting?

[@Arek_R.]

You shouldn't test them with a load set to keep the Watts, you should set it to keep current instead. If you set it to load 24W with 12V charger/powerbank then yes theoretically you should get 2A, but you will get some voltage drop across cables/connections, let's say 0.5V drop, you end with 11.5V on the electronic load and it will load it with not 2A but almost 2.1A and it will trip your 2A rated devico into fault mode because you just took more than rated.

[@Majromax]

> If you set it to load 24W with 12V charger/powerbank then yes theoretically you should get 2A, but you will get some voltage drop across cables/connections, In fact, it looks like most of the tests here are consistent with a USB cable resistance of about 200mOhm. The voltage read by the electronic load fell by about 0.2V per amp of current draw.

[@alexisfrjp]

The goal was to test the USBC PD module not the chargers/powerbanks.

[@brucestarr4438]

You should try your in-car adapter at 14 volts, like a running vehicle would produce.

[@AdamWelchUK]

Do you imagine there will be much difference? There is clearly a buck boost converter in there.

[@brucestarr4438]

@@AdamWelchUK the alternator on my pickup puts out 14.4v and 136 amps. I think it would be interesting to see if that made a difference in the results.

[@clintoncoker6]

Yeah, the lower voltage from his 12v battery would def be making life a bit harder for it. Giving it a 14v supply *might* get it up to its specs (not likely, but maybe a bit closer).

[@rich1051414]

Yeah I made a similar comment. The lower voltage would make even a buck boost converter struggle more, especially if the current protection regulation is blind to the input voltage(likely)

[@alexisfrjp]

The goal was to test the usbc PD module, not the charger.

[@j5892000]

So it's getting 20 v in from boosting the dc voltage which increases current draw then add in how much current the device being powered by it needs

[@mikeoliver3254]

That's a cool little adapter I may have to pick one up. I wonder how well I could run my TS-100 off of it with a USB-C powerbank.

[@AdamWelchUK]

I imagine it’d work reasonably well. Oddly better than the TS80 - which despite being USB-C actually uses Qualcomm quick charge not power delivery!

[@angelxd41]

@@AdamWelchUK QC2.0 12V-1.2A is enough to turn on TS100 but it could be possible adapt PD2.0 20V USB-C To jack barrel with a cable. Also TS80P uses PD not only QC3.0

[@AdamWelchUK]

Messian Hello. Yeah, check out @Brian Lough for a neat solution to the ts100 issue. He’s developing a PD to barrel jack solution (although I think there are some solutions already on the market) Is the ts80p a newer model?

[@angelxd41]

​@@AdamWelchUK TS80P a new model that accepts PD and Q.C3. On Aliexpress the are many cables with capacity to release 20v o 15v from PD source. In other hand if we want take power from Quick Charge, there are modules that forces change voltage 5v to 12v or you can make your own module using resistors and diodes. I think It's possible turn on TS100 with both technologies.

[@mostlymessingabout]

You can preset the PCB to fix the op to certain voltages. Come in handy

[@armyofwar9450]

Nice video :] I’m planning on buying a few soon.

[@rich1051414]

Are you providing the car charger with 14.4v? If not, that is why you didn't quite get to the rated amps. A car with a full charged battery will be 14.4v.

[@alexandreesquenet3736]

at 1:14, benefit of usb c is that both insertions side is ok, but I guess you mean't checking the unpopulated + polarity ^^

[@blubbspinat9363]

Very insightful video, thanks for the good work :o) To me it seems like the cable is a bit lossy and probably skewed the results on 5V a bit. Maybe it works better with a thicker one.

[@AdamWelchUK]

Possibly you are right. I was definitely seeing some voltage drop and the 1m usb cable is possibly the most obvious candidate. Half a volt at 3 amps isn’t too bad though - could be a lot worse!

[@blubbspinat9363]

Yeah, you're right, it's not too bad, but at 5V it's already enough that most devices will cut back on the current to keep the voltage above the 4.75V specified by the USB standard.

Good video. Would have been useful to see your source supply for the Rav power unit coming from a known good supply such as a bench power supply.

[@AdamWelchUK]

Sorry. I used my lead acid battery bank for the supply - 12v 136Ah.

[@MrBrymstond]

I love these amazing little device style videos that comes in handy, only china would give these things away for pocket change. If I had to buy this made in the US I would have to pay $10 ~ 15 I've purchased so many things from banggood I could never afford all of them from anywhere else not that I could even find one locally and even though the components are sub par they seem to last. So I buy the 10 or 20 piece packs. Plus they make for some interesting videos. Thanks Adam

[@pirateman1966]

I am shocked at how a communist country demolished the Imperialists at their own game! China was a shithole 40-50 years ago. It was considered to be yet another 3rd world country. Now, go to Shanghai, Beijing or any other large city, and its as modern as it gets and has more Millionaires than America. While America is in a free-fall in every imaginable way, including politics. Maybe democracy isn't that great, when citizens are uneducated and stupid!? Buying cheap from China, will drive us to poverty.

Glad you liked it. Cheers MrBrymstond

[@MrBrymstond]

[@jimnilles9791]

Is that PD board reversible with the power as well, I’m looking for something like this that I can hook a 12 V battery to power my laptop using the type-c cord?

[@alexisfrjp]

That's exactly what he shows at 8:40.

[@simmelj]

Did you figure out a solution for this? Looking for something similar myself

[@alexisfrjp]

@@simmelj 8:40

[@simmelj]

@@alexisfrjp Yeah. I saw your comment. Was just curious if he had figured out a "complete" solution. I'm also way out of my comfort zone with this stuff. But are you saying I could basically just hook this up to a 12.8v battery (with a fuse ofc) and it'll charge my laptop if I connect a USB-C cable between the two?

[@alexisfrjp]

@@simmelj 1. You don't say what is your 12v battery. A CAR battery? 2. You don't say if your laptop has a PD usb C port (Macbook, Thinkpad X1 T480/s, Dell XPS...) What you're looking for is a simple USBC PD charger. Since you want to use a 12v car battery, search "car charger usbc" and you'll find a lot. Take the 65w to be sure it'll be compatible with everything. USBC needs to communicate to enable higher voltage (>5V), that's why the small board presented in the video is useful. It communicates with the charger to provide a simple power supply. 12v -> charger -> cable -> board -> simple power supply The "reverse", is simply a charger and you don't need anything special since your laptop has already an internal board communicating with the charger. 12v -> charger -> cable -> laptop

I don’t think so, but I’ll check.

[@tim1398]

They can, you need to hold down the button to program those modes. Check the other you-tube videos.

[@The12231]

What would be the device to ramp up voltage, but keep current relatively low?

[@tgoregon]

Thanks for the video Adam. What are those other three pins on there for? Any chance they provide a way to pre-select the desired voltage without using the push button? I'd rather set it with a jumper, a resistor or an I2C interface.

[@AdamWelchUK]

Good question. I’ll investigate.

[@glennextra]

Well done video, Thanks!

[@j5892000]

It's good to know the adapter boosts. Does the adapter need 12 volts dc to boost or will it do 6 volrs

[@idontwantachannelimjustcom7745]

So is that enough watts to jump start a car? Set it to the 15v setting and when you get voltage drop that should put you in a normal car voltage range...

[@AdamWelchUK]

No I think most starter motors will need an awful lot more current.

[@lukepjd]

Hi Adam, I've just came across your video and I've been trying to get a trigger like this to power my 12v - 24v bluetooth amp boards for portable projects and I just can't get it to work it just flashes blue and doesn't strike up the board even when set to higher voltage. I have a high capacity wall plug too. Do you think it will work in my application? Thanks and another great video 👍🏻

[@kimslotte]

Can you us this ZY12PDN-board to charge in the other direction? Like having a 12V data source to charge a USB PD device? If not possible is there any other known boards that can do that?

[@AdamWelchUK]

If you want something to do that - I’d look at using the car adapter I used in the video. If the size and shape is a problem you could always remove the circuit board from the device its self.

[@officeez7980]

What could be the max wattage if we connect it with Computer USB 2.0 or 3.0 port?

[@davidprice2861]

You should never wear rings when working on circuits if you have a short thru ring it will ringbark your finger. EG: car battery + with spanner touching ring which grounds on car panel = white hot ring in 3 milliseconds.

[@AdamWelchUK]

Thanks. That is probably a good suggestion. Perhaps now I’m married I should take a step away from living on the edge!

[@gabrielpoa2007]

The car's charger input was 12V or 24V?If it was 12V is it increasing the voltage to 20V by itself?

[@AdamWelchUK]

Yes twelve volts in, twenty volts out. It bucks and boosts depending on the mode.

[@jairofarinas2217]

I wasn't sure if I caught it, but is the cable a limiting factor as well? I see that amps didn't go any higher than 3ish amps, but some cables are certified for 5 amp

[@alexisfrjp]

charger's limitation, not the board

[@shmeebopal]

Can this be used in reverse? I.e. your "power bank" is coming through the two blue screw connections. I'd like to power an electrical component using the USB-C. Urgent pls help

[@johnarmstrong3782]

Can't see the USB 3 connector being very reliable and robust over time.

[@AdamWelchUK]

USB-C connectors are fitted to mobiles which are being recharged daily - I guess time will tell but I know they’ve been around a year or two now.

[@fersunk]

@@AdamWelchUK My Galaxy S8 has a bit more of a year of life now. I charge it pretty much daily and is in healthy conditions.

[@vgamesx1]

Even if it wasn't very robust, just about any other connector beats the old micro usb standard, I've had cheap cables last as little as one or two months before they just slide out, only the good cables ever last more than a year, but an inexpensive and not particularly great USB-C cable I got from the store has held up almost as good as new out of the box after more than six months of charging my phone daily with it, so yeah I'd say it's definitely more robust from my experience using both anyway.

[@bren106]

My phone, tablet, vape device and camera batteries are all charged via the USB-C lead that has been plugged into an inaccessible wall socket since I got my first phone with that connection. Now on my third or fourth phone, so probably 5 years and never a problem with connections.

[@johnarmstrong3782]

Well, the comments are positive for USB C which is good to know. I've found that the curse of the lightning connector is that that one of the tiny tabs on the the cable goes black and fails relatively quickly when charging my iPad at 2amps.

[@j5892000]

So the trigger isn't boosting. It's just telling the pd car adapter is boosting

[@noweare1]

I guess I am a bit confused. When you set the e-load to 9 volts does your power bank autodetect that and outputs 9 volts or does the PD have to be changed from 5 to 9 volts to change the power bank to 9 volts.

[@AdamWelchUK]

Yeah the module requests a nine volt charge and the power bank delivers it if possible. So if you use a power delivery compatible device it’ll request what it thinks is the best voltage to make the quickest charge.

It's USB PPS (USB Programmable Power Supply) which some trigger boards don't support. Regular PD trigger boards will automatically choose the next lower voltage. So if you have a 12V PD trigger board and you have a USB PPS power supply, the output of the trigger board will be 9V.
