Powertraveller released an adapter to allow your Canon LP-E6 batteries (compatible with 5D MkII, 7D and 60D cameras) to recharge on one of their Gorilla portable power stations.  Now you don’t have to hunt around for a wall outlet when you need to recharge your Canon batteries during a shoot.

How does it do when the Price is compared to the quality?
The original post does not mention the 1D being compatible as they have totally different batteries the the other cameras listed.
Thanks for catching that. I updated the post.
