The Brunton Solaris is perfect for those who spend significant periods of time without access to electricity. It has 6 solar panels generating 12 watts of 12 volt current when unfolded, but folds up to a wallet size package for easy storage and weighs less than a pound.
The Solaris outputs its current to a standard vehicle 12-volt outlet. Any charger that can plug into a vehicle outlet to charge can be charged by the Solaris in conditions of reasonable sunlight. A set of 4 “AA” batteries will recharge in 2-3 hours, camera batteries — slightly faster.
