Many standard / cheaper USB chargers specified for example with 1A/2A Output will in real life only be able to deliver 70-80% of this. Secondly the conversion efficiency is also typically better, in better/stronger chargers, so it will overall also lower the electricity bill. However, there are big differences in quality of USB chargers (and cables), so by using a better / strongerВ USB charger you wil ensure it actually also have enough power available. If a USB device is designed for maximum Max 1A input, it will not be able toВ draw more than this, just because you connect it to 2A based USB charger instead. The more powerful USB charger, the more power the attached devices will also be able to draw, and thus obtain the potentially fastest charging time. So you can not buy a too powerful USB charger, thus damaging the equipment.

It's always the connected USB devices which control how much power it will draw from a USB charger - not the other way around. How powerful USB charger should I use with my equipment?
