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.
A
No it doesn't, it seems like none of the batteries have a date code
A
Micro and Type-C are input ports, they charge the battery. USB-A is the output port, which discharges the battery.
A
I guess that means they are safe to use the camera.
A
You can charge one or two batteries
A
You can charge 1 battery individually or 2 batteries at once if desired.
A
I've tried both, and it's pretty fast either way.
A
It has ports for two cables.
A
Compatible, it uses the included USB Type A to USB Type C cable, so you can plug it into a travel adapter with a USB port.
