Owner Reviews, Ratings, Comments and Criticism
I'm not sure why their product descriptions here and on their web site are such a huge miss, as they executed so well on the product packaging. Right on the outside of the box it has a stylized logo graphic of 10 watt power x 2, and then down in the feature list it has in bold "2 USB ports, each delivers 10 watts". So it can charge two iPads simultaneously at the high charge rate, or newer iPhones at a higher rate. Many other offerings out there may offer two USB ports, but they split 10 watts between the two ports, so be sure to vet the 10 watt claim.
