Charging with phone charger

Hi guys! I don’t know much about electronics, so what kind of amperage is safe to use if charging the Gamebuino Meta with a phone charger? I saw I had a 5.0V 2.0A charger, and I saw the Meta is 900mAh here:

However as far as I know 2Amps should not damage the device? It’s the voltage that matters?

Any help appreciated, cheers!

It’s perfect then.
The voltage needs to be the same while your power AC need to provide = or more amps than requiered. you can work with less amps but it will charge slower.

Ok, thanks man! Sounds good to go then! ^^
