## What’s the difference between 5V 1A and 5V 2A?

While we know that 5V 2A chargers can charge a smartphone faster than a 5V 1A charger. By simple maths, 5V 2A means 10W – that means double the speed of a 5V 1A charger, right? Unfortunately, that’s not the case.

## 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.

## Can I use a 2A charger for a 1A device?

The current draw (Amperes) is controlled by the device you plug in. So if you plug a 1A device into a 2A charger, it will still only draw 1A. … If you plug a 2A device into a 1A charger, you will only get 1A. The device will charge more slowly (1/2 speed roughly) but everything will be fine.
