You may watch the video right here:

I appear to have been accumulating a complete bunch of USB powered units. I’ve acquired the mini hotplate, a small energy provide, and two USB soldering irons!

The mini hotplate takes 20 volts and makes use of round 60W when it’s heating up.

The facility provide additionally desires 20 volts.

And one of many soldering irons is restricted to 12 volts, and the opposite will use 20 volts.

It’s not a large downside, however I do solely have one 65W USB-C provide coming into workbench. I would like extra, I would like a lot rather more!

There don’t appear to be any powered USB-C hubs, so I went buying on AliExpress and ultimately got here throughout this good board:

This has 4 customary USB sockets on the highest which all assist QC2 and QC3

And it’s acquired 4 USB-C sockets on the underside:

These assist just about all of the protocols you may consider!

Testing out how a lot present the board can ship offers us a terrific end result – it may simply do 65 watts!

For these of you who’re fascinated about what’s on the board, I’ve tried to seize the IC numbers on this image:

There’s a datasheet right here for the chip right here: (it’s all in Chinese language although!).

It’s fairly good although – I’ve now acquired 4 USB-C provides on my bench, all of them able to 65W of energy.
