How Does It Work?



Elegant Design




Slim design and simple functionality means it slips straight into your pocket and activates with a shake or tap.


Specifications


High Voltage, big current & fast charging.

We raised Quarter's battery core voltage from the normal 3.7V to 7.4V. To ensure it's performance & stability under higher voltages and bigger currents, we redesigned Quarter's circuit. Furthermore, we managed to reduce the internal resistance by optimising the Li-Ion polymer battery. This gives Quarter the ability to endure higher charging power.
