Portability Solution? - dsommars - 02-24-2023

I’m trying to come up with a way to use my FK… well, in the *field*… without the need for a wall adapter or a short-lived 9v battery. I searched this forum, but couldn’t find anything like what I’ve described below. Any feedback is appreciated.

I have a USB power brick that has 9v@2.77A among its USB-C PD-regulated output voltages. Since the amperage used is determined by the device drawing the current, I figure I should be able to plug a “USB-C to Barrel DC plug” cable into my FK, as long as the barrel is the correct size, is center-negative, and the cable has a PD chip.

Does anyone see a reason this would release the magic smoke from my FK? Has anyone tried a similar solution?


Best regards,

My power bank is model HX200Q4. It’s similar to this one below, but 36,800 mAh. (My thinking is that even the USB-B would work with its 9v@2A on the quick-charge ports.)

Here’s the USB-C to DC Barrel cable at Adafruit.
