I have a Raspberry Pi 3 B+ that I bought as part of a kit. However having used it for a little while I have noticed that the packaged power supply isn't providing the pi with enough power causing the under voltage symbol to be on the screen semi permanently.
I tested my pi with a power supply with output 5V-5.4A (2.4 per port) and random micro usb cable and it worked flawlessly (even with some pressure on it). However that setup doesn't include a switch.
So my question is can anyone recommend a power supply that will work under pressure that includes a switch?
I've tried to find one myself but I find Amazon's description/pictures don't match so struggling to find a reliable source.
