This is a great item to extend the battery life of your light. Helps a ton if you are running your light at full power.
Very nice addition to my overland setup. The light is well build and sets up easily. The light options are nice when your not needing a lot of light. Overall one of the better things I bought in a while.
Used it for the first time over the weekend. Ran the light all night on high
Very good I my light all night long and they didn't die Very good
charged quickly, solid design, easy to use.
