Product description

Why my power bank provide fewer charges than expect?

Usually an external battery could supply 60%-70% power to other devices. Approximately 30-40% of the battery capacity is lost in circuit heat and voltage conversions.So a fully charged INIU 5500mAh power bank can offer 3300-3850 mAh to your devices.

How to calculate the possible number of charges?

Industry-standard formula: (Power bank capacity × 65%) ÷ Device battery capacity ≈ Number of Charges.

eg. (5500mAh Powerbank × 0.65) ÷ 3279mAh iPhone14 battery ≈ 1.0 charges

How long does it take to 100% recharge?

You can recharge this mini portable charger using the built-in USB-C connector or a 15W charger, which takes approximately 2.5h to charge fully.

Is it allowed on airplanes?

Yes, our 5500mAh power bank meets the regulations of TSA(Transportation Security Administration) for carrying board(≤100wh≈27,027mAh).

Does it support pass-through charging?

Yes, our power bank supports pass-through charging. You can charge both the power bank and connected devices simultaneously.
