This is a replacement for a device that was working great. It's not like this. First, no charger is included. There is no mention of this in the online description. I used an old charger and instead of constantly showing red lights charging both the battery included in the flashlight and the extra battery in the holder, the lights change quickly and sitting on the bedside table can drive you crazy at night. I don't realize that the device is actually charging. It seems silly and a bit misleading to sell this without the ability to connect to a power source.
