How It Works:
USB ports have 4 lines. Ground, 5V, D+, D-. The D+, D- or data lines are used in most mobile devices to determine what charge profile that it should use to charge itself. Legion Meter modifies the D+ and D- to signal your mobile device to charge at the fastest possible setting no matter what USB port you're connected to. Charge acceleration is made possible by the patent pending, dynamically switchable architecture.
The device also features a resettable milliwatt-hours counter that can be used to determine the remaining capacity of your battery.
Legion Meter has far surpassed its goal of $10,000 with over $230,000 in pledges on Kickstarter. There's only a few left at the $49 pledge level and then the price jumps to $69.
