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).

Small, powerful fast charger with two usb c ports

Great charger. Will quick charge iPhone to full and iPad to 50% simultaneously over usb c and its very compact for 10k mah. Deducting 1 star for case finish, the plastic always looks dirty and smeared from fingerprints even though its a matte type finish.

BEST charger on the market!

This is my favorite charger. The paw print in the front gives clear charge levels, and it is the perfect size and has multiple charges per use. Perfect size: used 4 inch lightning charging cord and folded phone and charger together which created a neat "pack" that fit in pouch, purse, or any small carrying item. Multiple charges of items after one full charge of device. It is very reliable, portable, has a built in cable, and I won't leave home without it.
