What happens if you use the wrong power adapter?

The device could power on and draw more current from the adapter than it's designed for . This could cause the adapter to overheat or fail. Or, the device may power on, but the adapter may not be able to keep up, causing the voltage to drop (see voltage too low above).

What happens if I use a higher voltage adapter?

Using an adapter with a higher voltage will cause the connected device to detect an overvoltage . An AC adapter supplying electricity at a higher voltage than required will cause the connected device to run hotter.

Does the voltage of a charger matter?

So it is important to match voltage between the charger and device . It doesn't matter if the power supply / charger can provide more current then the device requires. Providing less current will prevent charging or slow it down the same as a poorly designed charger can also prevent charging or slow it down.

What is a 5V 1A charger?

chargers. A 1A device means that, for a power supply at a certain voltage (5V for USB), the device will “ask” for 1A from the power supply . For a 1A charger, it means the electronic devices in the charger can handle 1A before they break.

What is 5V 2A charger?
