Powering Raspberry Pi devices from a Fritz!Box USB connection

Posted by jpluimers on 2017/03/30

I tried to power both Raspberry B+ and Raspberry 2 B devices via the USB ports of both a Fritz!Box 7490 and Fritz!Box 7360.

At first this works, but the Raspberry B+ devices over time would become unstable: not being able to ping and/or boot.

So below are some links on power requirements and powering Raspberry Pi A, B, A+, B+, 2B and zero.

Fazit/TL;DR: use an external power supply when available.

BTW: The 2B is way faster which begins at boot: booting (with OpenSuSE Tumbleweed) until eth0 responds to ping is around 50 seconds.
