Question: Should I Charge My IPhone With 1a Or 2a?

Will too much amperage hurt a device?

A higher voltage than a device is designed for will most likely blow up some components, but amperage is derived from how much current is actually drawn, based on the device’s resistance, so having “too much” is not a problem and will do no harm..

What is 1a and 2a in power bank?

A device that charges with 1 amp can be used with a 1A output charger and will charge at a normal speed and within a standard time.
