3D printing an external battery charger? Then getting it wired!

I’d buy a spare battery for my FP4 if I could charge it externally. To bad we’re such a small market. It might cost as much as the FP4! Maybe there will be one for the FP5 by the time the FP5 gets to the US. Anticipation!!

I was thinking of charging a spare battery while running around with the phone and its battery.

Swapping them in the phone to keep them charged seemed cumbersome.

If you want to charge while running around, why not just use any of the abundantly available power banks? That also spares you the trouble of switching off the phone to change the battery.
