External charger for the FP2/3

@HisDudeness

I don’t own a FP yet, but the availability of an external charger might be what finally drives me into buying one

Unable to charge battery

As an example, this universal smartphone battery charger here works for the Fairphone 3 battery: It works because the 2 contact parts are thin enough and stand out enough. So, even if this particular charger might not be available somewhen somewhere, if anybody is in need, just look for universal chargers with similarly shaped contacts.
