Subject: Power Supply for the A500 Mini...
Everything I've come across says to use at least a 2 Amp USB power module. Just ordered a 3 Amp phone charger charger. Getting a pair of them with 4 connectors.
My question is with a 3-3.1 Amp power module...is there any danger of frying anything like the A500...RPi 3B+ or to recharge a phone?
Nope more is better than less.
I have a 30 amp Mass charger brick I will
eventually make into a project box. Eventually going to make a Mass battery
pack with it so I can run multiple USB devices at once. Pi's and other fun toys while on the go.
Thought so. Have had issues in the past of trying to power some of these ARM boards from a PC USB port or a power brick "supposedly" able to handle the requirements.

The ideal way to go is if a device say's 3amp required, get a 4amp. If it say's 2amp's get a 3amp.
That gives the power supply breating room so to speak, and it's not
working at max capacity to supply the requred amp's. The best idea is to
not push the psu past 80% capacity.

I got hold of a "standard" 5v 5A supply and wired a USB-A socket onto it to power my piZero and assorted stuff hanging off it. 2x Cameras and a thermometer, on a USB hub. I found the nominal 2.1A wall warts would struggle... it also struggled supplying enough 5v straight the on board USB ports too.. so wired the hub directly into the power supply as well..
Not sure about USB3 ports but 1s and 2s only supply the regular 500mA per port.
