Legion Meter is a device that can safely accelerate your smartphone/tablet's charging speed up to 92%. It also features a built-in multimeter for displaying voltage, current, power, and milliwatt hours on the integrated OLED display. Legion Meter installs in seconds and is fully plug and play.

Legion Meter's intelligent algorithms learn how you're using your devices and calculates your energy usage at roughly 500 times/second giving you ultra accurate power metering. Legion Meter's high contrast OLED display shows you precisely your USB port's voltage, current, power and also includes a precise mAh capacity meter counter for you to diagnose the batteries of all of your portable electric devices.

Legion Meter has two selectable modes of operation, Charge Acceleration/Data Protection and Data Passthrough. In charge acceleration mode, the data lines D+ and D- are physically cut from the input of side to the output side of Legion Meter. This completely denies any data from passing through to your device giving you ultimate data protection when charging your devices in public areas while simultaneously maximizing your charge speed. Data passthrough mode connects the D+ and D- USB data lines from the input side to the output side of Legion Meter allowing you to transfer data normally as you would with a standard USB cable.

Legion Meter's Watt Hour (mWh) mode is useful for analyzing the storage capacity of batteries. Much like how a gas pump counts the amount of volume of gas that gets pumped into a vehicle's gasoline tank, the watt hour meter measures the amount of energy or (Watt Hours) that gets charged into any battery. This is useful for discovering the true storage capacity of batteries. Press and hold the button to reset the counter to 0.

Legion Meter also employs many additional advanced features such as automatic screen saver mode, a double buffering graphics processor for seamless OLED transitions and intelligent battery monitoring algorithms and a dynamically switchable Apple and Android Charge Accelerator circuit.
