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.

Yes, if you want to charge faster, you can also use a wall charger 5V/2A to charge the battery.

Normally, it is charged and discharged 300-500 times, and after 300 times, it begins to decay to 80% capacity, which is manifested in rapid power loss.

Yes, it charges them quickly and then the light for that slot turns green. To me, that's an indication that it's going to lose power because the battery isn't hot the next day. (No, they don't need to be charged overnight, they're fast.)
A
Yes, micro USB and USB-C are supported. It's great because you can use any micro USB cable and USB-C and take it with you.
