Anyone ever use these super chargers?

There are people commenting without reading, apparently. It's called "super charger" because it's putting out 3 amps, which is enough to fast charge a tablet, let alone your phone or gps. And it's made in Korea, where they don't use slave labor and stolen patents, so the cost of the product will reflect that. Stop comparing costs of goods produced by Chinese prison labor, it's not healthy.

Agree with above posters, it's a very clever design that doesn't clutter handlebar real estate. Going to order one, let me know if you want a review.
