that sounds like a good idea
a hybrid between powerbank and battery case
community could probably make some prototypes, just as a proof of concept
I would be interested in trying one out

how do you carry your spare battery? I did it inside the original plastic envelope that came when purchased. during some bike routes I did having my FP4 as GPS this saved my life.
how do you charge your spare battery? what I did was:
- every Monday I charged the FP4 to 100%
- power it off and replace the battery
- use the new battery the whole week until next Monday between 15%~20% and 80%~85%
so you have a spare battery during the week charged at 100%, if I used the spare I do the se steps whatever the day of thw week was
You're making a battery last a week in an FP4?
LOL
So it's like fairphone version of this https://a.co/d/9OfZpOu , right?
Yeah kinda ... but that it can also charge other devices when not connected to a charging source.
Use case 1: Charge FP batteries
The "box" is connected to a charging source, which charges inserted batteries
Use case 2: Charge USB devices
When the batteries inside "box" are charged, connecting a USB device to this "box" will start charging the connected device
Use case 3: Swap out the FP battery from this "box" with a discharged battery in the FP
It would be a great bonus if it could also accept more generations of FP batteries. FP3 or FP4 and newer would probably be most realistic.
