Legion Meter is a USB multimeter with integrated OLED display designed to accelerate your smartphone or tablet’s charge speed up to 92% faster. A multimeter is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter would include basic features such as the ability to measure voltage, current, and resistance (source: Wikipedia).
I backed Legion Meter on Kickstarter on the 29th May 2014 and it was funded successfully on 19th June 2014 after raising US$416,268 out of their initial goal of just US$10,000.
