This is a rechargeable LED tent light, with a built-in fan.-The power supply/battery pack, is contained inside the top of the fan. The battery is not off the shelf, it is constructed specifically for this unit, not an AA/AAA/C/D battery. Take care in trying to open the top, there is one screw holding one side on, the other side is held in place with a couple of very weak pressure clips, easily breakable.-The internal battery can be charged from the solar panel on top of the unit, or by using the micro USB port on the side of the unit. When the micro USB port is charging the unit, the red LED on the side panel will light. This LED will stay on red as long as the micro USB is supplying power, and does not change when the battery is completely recharged. We suggest not leaving the unit on charge for more than 8 hours using the micro USB port. This assumes no LED or fan usage while plugged in for charging.-The side LED will turn on and be blue when using the fan. The fan has 5 settings, off, ascending speeds 1,2,3,4.-The side LED will not turn on when using the LED lights. The LED light switch has 5 settings, off, bright white, dim white, flashing white/red LED's, solid red LED's.-There are 3 flip down LED light panels on the unit, they seem to work well, but there is not tab or handle on the light panels, so it is often difficult to fold the light panels down, for direct down lighting.-No idea what the charging capacity of the solar cell is on the top of the unit.-There is a USB port on the side of the light/fan, and can be used to access the internal battery, for charging/operating other devices. This full size USB port is an output port, while the micro USB port is a charging input.Will add notes later after summer camping season.
