I was getting the low power icon with my pi3a+ joystick build.

I'm using a regular usb plug to the wall (like a phone charger thing) which goes to a panel mount plug and then into the micro usb of the pi.

I got a 2a plug and I'm still getting it. I have no other perihperals plugged into the pi's other usb port.

???

Just wanted some thoughts before I open it up and actually check the amps on some +5v & GND points on the pi with my multimeter.

2 A is enough for the Pi 3 A+. Mabye your cable is of poor quality and drops some voltage. Try another one

I'll try another cable. The one I'm using was brand new from Amazon, but doesn't have an amperage rating on it...

Thanks!
