Kickstarter significantly improves speed of your existing charger

The Legion Meter plugs into your existing USB charger, and your device plugs into it. The Legion Meter interacts with your device’s charging system and optimizes the flow of current into your device, significantly reducing the time it takes to charge your device.

Check out the page, watch the video. I think this is a brilliant idea, though I think they should offer an option that dumbs down the data display. Instead of showing you detailed numbers for charging speed and capacity (IMO, not many people will care about that), how about a simple number that shows you time left ’til full, or perhaps an estimate on the number of charging cycles left on this battery.
