Compatibility: Compatible with all devices with USB-C port. If you need to charge an Apple device with a Lightning port, please use a Lightning cable (not inclueded).
Why my power bank provide fewer charges than expect?
Usually an external battery could supply 60%-70% power to other devices. About 30-40% of the battery capacity is lost in circuit heat and voltage conversions.So a fully charged INIU 20000mAh power bank can offer 12000-14000 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. (20,000mAh Powerbank × 0.65) ÷ 3279mAh iPhone14 battery ˜ 4.0 charges
How long does it take to 100% recharge?
It depends on the power of the wall charger used:
27W charger - 3.9 hrs, 15W fast charger - 6.8 hrs.
Note: Please recharge via the USB-C port.
Why doesn’t it charge at max power all the time?
INIU power banks feature a Smart Temperature Monitoring System that adjusts output to prevent overheating. It delivers max power when your device is low, then reduces power to protect your battery and improve efficiency.
Is it allowed on airplanes?
Yes, our 20000mAh power bank meets the regulations of TSA(Transportation Security Administration) for carring board(=100wh˜27,027mAh).
