A portable way to charge your precious phone whilst on the go or otherwise not connected to the grid -- never again be stuck with a stupidly expensive paperweight in your pocket.

5000mAh Lithium-ion polymer battery cells in a super slim 10.7mm aluminum case, Xiaomi's thinnest yet. Sourced from reputable suppliers, the premium battery cells have enough capacity to charge most smartphones on the market today up to two times before needing to be recharged.

World-class chips are built into the power bank which are not only safer but also improves the charging conversion rate by 93%. They also act to stabilize the discharging voltage, and the advanced resistance-capacitance sensors optimize charging efficiency and longevity.

Plays well with others  -- the power bank is compatible with a wide range of devices. It can automatically adjust its output level based on the connected device to ensure safe and optimal charging for all your gadgets.

The smooth edges of the power bank are ergonomically friendly and easy to hold. The anodizing process creates a stronger surface that is resistant to fading, west and corrosion.
