These are new products; they get about an hour of usage time; but, it takes about 3 hours to charge from 0% to 100%. It uses a standard micro USB to USB cable. It will work with an iPhone style charging brick, or just use your computer.
The LED light also comes with a filter, a defuser, and a ball / hot shoe mount to attach to a tripod.
There are 3 different light models; 4-LED, 6-LED, and 8-LED. The filters from the 6 and 8 model are swappable. The battery life on the 4-LED isn’t quite as good but it takes less time to charge.
This particular model I purchased is a 6-light LED portable lighting kit. It features three stops of lighting, 1-hour of lighting time, and a 420 @ LUX.
