In my ongoing quest to find/create a multi-channel USB charger that really can deliver full power on all its ports at once, I've evaluated this Quad Type-A module and confirmed that it does truly provide its full rated power, without anything melting. (Next up I will be testing some much more powerful Type-C chargers that claim to deliver 260W and 280W total respectively). https://s.click.aliexpress.com/e/_c4ObxhEb

Okay, here's an update on my quest to find a USB power delivery solution that contains a minimal amount of lies.

All the "820W GAN Charger" etc products on Amazon, Ali, Ebay etc are made of lies, they can deliver maximum output on one port only and as soon as you connect a second port they die in the arse.

So, previous post was a Type-A delivery board that really can run all four channels. Onward!

This (https://s.click.aliexpress.com/e/_c3jXwvV5) is a 4-way Type-C module with each port rated for 65W. At 20V and 3A it comes close enough that I'll give it a pass. The voltage sags a bit from 20v to around 19v but giving the benefit of the doubt I will attribute this to my utter garbage lash-up of load cabling.

Recommended, you will not regret putting 240 watts in your trousers.

Our next contestant is a 100W dual output charger. I just tested the USB-C port, it really does deliver 100W and safely shuts down if I try to draw more. https://s.click.aliexpress.com/e/_c3lTcROR

@Unixbigot I bought my last two bricks from #pine64 (open hardware company) and never had any issues like I had with Aliexpress purchases https://pine64.org/devices/pinepower/ They also have a desktop version which has a nice display https://pine64.org/devices/pinepower_desktop/

PinePower

PinePower, A 65W GaN Power Supply The portable PinePower packs plenty of power in a very compact design. It is capable of powering or charging multiple PINE64 devices; such as the Pinebook Pro, PinePhone and the PineTime simultaneously. If you’re interested in getting the Pinecil, our soldering iron, then we highly recommend the PinePower to ensure optimal power delivery.

This 140W dual-port USB-PD board could only deliver 100W at 20 volts. It supports 28v so maybe it can do 140W at 28v, but I don't have any 28v PD sinks. So this one gets a conditional pass.

This one is the real McCoy. It promises 140W and it really does deliver 7 amps at 20 volts. The 5.5mm barrel connector cable (rated for 2.5A) got a little warm there, so use those fat pads instead!

ETA: this one has an I2C port, so one could monitor its usage using a microcontroller or computer, to understand what it is up to. Or add an LCD screen, for example. Many of the chips used in chargers support an I2C control/status interface, but very few of the modules that you can buy wire it up.

And now THE MAIN EVENT. Dual 140W USB-C ports. 280 watts under your skirt for all your mad science needs.

And it DELIVERS. https://s.click.aliexpress.com/e/_c4kTltc7

So there we go. FIVE HUNDRED AND FIFTY WATTS of USB ports, for the ultimate portable or desktop USB charging station. Just add your favourite bucket of spicy electrons and you too could be saying THIS IS FINE!

Coda: you can engage my “technology concierge” service via the link in my bio if YOU have a tech sourcing problem that needs researching.

ETA: this little board promises 65W but i ran it up to 100w before it shut itself down safely.

@Unixbigot Can you be trusted with this power?

Hopefully no, that sounds boring. BE THE RECKLESS POWER MAD ROBOCROC CREATOR YOU WANT TO SEE IN THE WORLD.

@mirabilos every few months i run the numbers on “usb teakettle yet?”

@Unixbigot Silly question - can you plug any old device like a phone, tablet, or USB-C-powered laptop into those ports and get just what you need, or does it deliver 140W of underwear-igniting savagery to whatever is plugged in?

Kit Bashir Mar 4

@kauer Usb Power Delivery is a negotiated thing, you get plain old five volts at half an amp maximum until the device under charge uses the USB Type C wires to request something different. So a device will only get a voltage that it asked for.

@Unixbigot thank you for doing the heavy lifting here. I spent ages searching for something that could actually charge my work laptop in my car and after multiple false starts ended up breaking down and buying an Anker supply for $way2much. I still want to install some new permanent ports rather than 12V/acc adapter and these look like a possible option

@Unixbigot Do you have a pinecil? I'm reasonably sure they can ask for 28V.

Kit Bashir Mar 4

@tj not a pinecil. Tried my other irons they all top out at 20.
