So I got a crazy #idea for #Fairphone ... Would be fun if some one could proxy this idea to the official folks there. @gael, @WeAreFairphone, @fairphone ?
Fairphones has a replaceable battery. Sometimes I would like to have a spare battery with me, to replace on-the-fly. In some situations, that is more convenient than to have the extra "dongle" known as an external USB battery pack.
The challenge is: How do you charge them? Back in the old phone days, you could have desk chargers for spare batteries. Another challenge: How do you carry external batteries safely?
So I got this crazy idea. Combine those two challenges! With an additional twist!
What if there was a portable "box" which could carry up to two Fairphone batteries, with a USB-C port to charge them. But! Let it also function as a USB-C battery pack which can be used with Fairphones (via cable) or other USB devices.
That gives you a portable battery charger, battery carry case for 2 batteries and a 3905 or 7810mAh OTG battery pack (based on FP4 batteries, depending on if 1 or 2 batteries are present).
If these cases can be designed to support more FP battery generations, you get something which could even be quite sustainable.
