So I'm connecting some new hardware together for a new rig. It's a powerboost 1000 + 2x 18650 li ion batteries, a pi0 and an rfm69 radio transmitter. I was wondering if there is any difference to using the USB power output of the powerboost to power the pi0 through it's usb port, versus connecting the v5 pins and the ground pins of both together? I looked online and people were saying that the usb option is better since it has a fuse to protect it, but I think that it's not there on the pi0, so it wont matter. Is there anyone more knowledgeable than me that knows this for sure?
