I can't give you an exact time to charge the battery - too many variables, how discharged the battery is, how old the battery is, etc. But I can tell you that what you plug in makes a huge difference. I use a small adapter that plugs into a 110V outlet instead of using a computer's USB port, and in particular a 5V 2A fast charger for my phone works best.

The battery will automatically match the applicable voltage of the camera, and the use will not be affected

This charger comes with 5V USB input and Micro-USB cable. It can be charged by any device with 5V USB output, such as wall charger or laptop or power bank etc. It's not from 110V or 220V.

Any USB charger will do. As long as it accepts European voltages, your phone charger will work. Super handy if you want to charge while driving.
