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: (Power bank 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 - 2.8 hrs, 27W fast charger - 2.0 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).

Would buy again

I'm so glad I got this for my recent flight. It's lightweight and TSA approved. It did the job twice with plenty of power remaining.I especially love the attached transfer power cord, which acts as a strap until needed. Very convenient. I would definitely buy again.

Bought multiple.

I have purchased these for each one of my family members for when we travel. They are easy to charge and easy to use. They are durable and continue to work great even after being dropped a few times. Size is great because you can slip it in your pocket.
