## Questions & Answers

**Q: Why my power bank provide fewer charges than expect?**
A: 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.

**Q: How to calculate the possible number of charges?**
A: "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"

**Q: How long does it take to 100% recharge?**
A: "It depends on the power of the wall charger used 20W charger - 5.4 hrs, 15W fast charger - 6.6 hrs. Note: Please recharge via the USB-C port."

**Q: Why doesn’t it charge at max power all the time?**
A: 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.

**Q: Is it allowed on airplanes?**
A: Yes, our 20000mAh power bank meets the regulations of TSA(Transportation Security Administration) for carring board(≤100wh≈27,027mAh).

### ⭐⭐⭐⭐⭐ Bank it , use it !!¡
*by G***Y on 11 February 2026*

These power banks are just the ticket for when we were on our travels & had been quoted that charging device may be difficult for where we would be travelling !!! Brought two too as the Mrs would have used it more ?? Added bonus too with the built in light / torch which was great when needed ... I managed to charge my phone 4 times without any problems & still had charge left within the power bank & was made very easy with the built in cable & variable charging ports to recharge the power bank to top up when needed too , the design I feel is pleasing to the eye but a tad heavy in weight but if in a bag / sholder bag you wouldn't notice .. 10/10 all round .
