5V Mobile Power Supply USB Battery Charger 18650 Box

I know what you're thinking: "It's a battery box! Why would you need instructions?" But this box has several features that are a bit confusing. First off, the on/off switch both turns on power to the USB port and a LED light. The LED is an indicator that the USB port is being used. Secondly, the buttons on the side indicate the amount of power left on the batteries. They're colored oddly, however, so don't be fooled by blue and green LEDs. Also, when charging, a red LED comes on and when fully charged it changes to green.

Ports

The large, regular-sized USB port is the outlet from the box (charges other things)

The mini-USB port is where you charge the batteries up at

The port in the middle? I have no idea. If you can figure it out, let me know.

Altogether, this box is a pretty good bargain for $12. I use it with a solar panel to keep my devices charged, especially when camping, and it has served me well.

No instructions or charger included. Ports not labeled. Batteries loose charge even when turned off and not in use. Not very well made.
