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 10000mAh power bank can offer 6000-7000 mAh to your devices.

How to calculate the possible number of charges?

Industry-standard formula: (Rated capacity × 65%) ÷ Device battery capacity ≈ Number of Charges. eg. (10,000mAh Powerbank × 0.65) ÷ 3279mAh iPhone14 battery ≈ 2.0 charges

How long does it take to 100% recharge?

It depends on the power of the wall charger used: 15W charger - 2.7 hrs, 20W fast charger - 2 hrs Note: Please recharge via the USB-C port.

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.

Is it allowed on airplanes?

Yes, our 10000mAh power bank meets the regulations of TSA(Transportation Security Administration) for carring board(≤100wh≈27,027mAh).
