Kingrex UPower User Guide

Features of U Power:

1. A charge/discharge toggle switch that fully separates the charging and discharging
circuits. This prevents any external noise interference from the AC charger or wall
outlet when it is used for discharging as well as ensuring a pure and interference free
DC output.
2. A constant current source based charging circuit that ensures the charging current is
within the acceptable level for the battery for a significantly extended battery life.
3. Independent charging/discharging protection circuit board on the of battery cell to
protect each cell of the battery against damage caused by over charging and
discharging. Short circuit protection is included.
4. Independent charging and discharging indicators for a clear display of the status of your
UPOWER: charging, charging completed, in use, and power low (lower than 10% of
total capacity).
5. A robust and stylish aluminum casing that not only protects the internal PCB and battery
cells but also has an excellent cooling function.
6. Uses the industry leading Sanyo 18650 Lithium-ion cells with up to 2600 maH capacity
and a lifetime of 500 charging cycles.

5V with a USB connector for any mobile device with a USB charging port including:
mobile phones, MP3 players, earphoneamp, PDAs and the like.
