Powering a Xiegu G90 off a 100 watt usb c output

I have the Bluetti Handsfree 1 and am looking to power my Xiegu G90 off it using the DC powered USB C output instead of using the AC output and using a converter. Ive seen a youtube or 2 that say I will need a buck converter and make a special cord. While I don’t doubt this info I am wondering if anyone has actually done this or can point me in the right direction on exactly which converter to get. I have tried to make this work using a 12 volt cigarette lighter cable with a USB C connector on the end and it’s a no go. Any thoughts?

I don’t have a good mental view of this, but it seems like you are trying to draw power from USB-C to run the G90. The G90 only seems to take 12V in via power-pole.

USB-C is 5 volts so you will need something to step up that voltage from 5V to 12V. I saw some on Amazon that may work. My concern would be amperage. You need to provide 6A at 12V to power the G90 at full transmit.

Exactly what I seem to be finding out so far. So I’ll be searching for a 12 volt 6 amp step up buck converter. Does the usbc cord need to be rated for 100 watts. Probably safe to say yes. Thanks for getting back to me. I think I can do this. Seen someone do it on an icom on the tube. Also people making this work to charge their HTs

I don’t know about the cable rating.

USB-C in it’s Power Delivery (PD) incarnartion can supply a variety of voltages including 12v. You’ll need a “12v trigger cable” (Amazon) to get a USB-C PD supply to deliver the right voltage. They usually terminate in a barrel connector that you can adapt to the G90 input. The G90 won’t take 100W on transmit but you should allow for 40W if we assume that it’s 50% efficient. That’s less than a laptop would take from a USB-C source when charging.

This one will do 36W -
