## 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).

### ⭐⭐⭐⭐⭐ Amazing Power Bank !!!
*by A***S on 25 January 2026*

Wow .... very impressed !!! , I bought this power bank to use with my heated gilet .... I needed one that would last all day outside , and I did a really long search into brands /reviews etc , changing my mind almost daily , then finally settling on this one !! It did not disappoint at all , it did take a while to charge , but that wasn't a problem ... when it arrived I did think that it might be a little heavy , but actually once it was in the gilet storage pocket , I didnt notice the weight at all , even when I was running , totally forgot it was there and it didnt make a difference at all ! I turned this on approx 6.50am , and it lasted me the whole day , it was switched off around 5pm when I got back in my van to go home , and it was still showing 33% battery 🙂 ..... It feels very well made and love the non slip casing its housed in , my other power banks do tend to slip through my fingers .... It comes with a fab little mesh carry bag and charging cable , and it was just plug and go .... very very impressed ... when funds allow I will look at buying another as theyre very handy things to have around , especially when I start camping again in April ... I bought this based on my own reviews and research and am not affiliated with the brand in any way .... but would def recommend them !!!
