My phone charger (Male wall adapter to female USB) says it outputs 5V @ 2A on the back. I want to use it to plug a Male USB into.
I guess my question is; is that 2A always being output? Or is it a maximum of 2A?
I have a homemade project, that is simply 10 RGB LEDs with 5V going to the common anodes (parallel), and only the R and B are going to 200 ohm resistors going to ground to show purple light.
I tested this with the USB cable in my computer, but I want to make sure it's safe to use with this phone adapter before I plug it in. Thanks!
