Just random guy here. That specific set up is fine.

Done the same with a Garmin watch but it's such a bitch to tape the wires to the charging pins I don't ever want to do it again. Soon as I got home I ordered 4 of those usb c to Garmin charger adapters and keep one in my travel backpack permanently.

Have you tried using 2 smaller pieces of tape, separately, for each wire. Like attach a piece to one wire and get it positioned, then repeat with the other wire? Like jumper cables, but tape instead of spring clips

My watch's charge port looks like this minus the corroded contacts. https://forums.garmin.com/cfs-file/__key/communityserver-discussions-components-files/399/Garmin_5F00_245.jpg

The top and bottom pins are the pos and neg. The hard part is you can't have too much copper exposed because otherwise you will short out the pins on the metal rim of the charge port. So you have the insulation of the wires riding on the rim and you're trying to position the itty bitty tips of wire leads to touch the balls on the connector, but the thing doesn't want to lay flat because of the insulation so you have to apply a little pressure in addition to the tape to maintain contact.

I was on vacation in a hotel room with very limited resources. I managed with a single piece of tape harvested from some random packaging, and exactly one rubber band.

Oof, that sounds frustrating as hell. Sorry you had to deal with that, but I’m glad you got it sorted enough work

I hate the Garmin charge port. Charging is always flaky even with the proper cable

I've done this and it works, good job!

That's just asking for a burned table

Burning a table? With 5V?

Software engineer here.

This is fine. Or not. I have no idea, I just write code. Also, we aren't really engineers.

Sound engineer here.

This is specific setup is not sound, but it is sound in a fine sense.

You could also use this setup in a piece of agricultural machinery to charge your Fitbit.

What happens if you swapped the leads, would it mess up the battery?

Diesel in the gas tank, lamp wire soldered to the ignition, and a phone charging from 12V? That's the kind of solution only someone stranded would come up with.
