## 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).

### ⭐⭐⭐⭐⭐ Good value 20000 mAh Power Bank
*by K***K on 4 December 2024*

This is my 3rd (or 4th, I lose track) 20000mAh power bank from INIU. Not because I keep replacing them, but they are so good I keep adding them to my collection. I was very impressed with my first one, bought several years ago I added a few more. They are moderately hefty (fair chunk of cells in the bar of soap-shaped case for 20000 mAh) but actually quite a small footprint. It has a nice clear readout of % charge left (0-100% shows in 1% increments) and a handy (ish) white LED light / torch function, which surprisingly, I use fairly frequently (push button on the side which activates the torch with a double press or turns it off with another 2 presses. Port-wise, 2xUSB3 (standard A size, blue coloured insert) for output to a device, and a USB-C (in/out) which allows re-charging of the bank or charging of a device (not at the same time, obviously!). The selling point for me is you can long-press the power button to turn it off but more importantly it stays ON when charging very low current devices e.g. some earbuds or smart watches (or powering some low power USB devices such as LNAs for SDR applications). Many powerbanks turn off if only a tiny current is being drawn, these don't which is why I own 4. As a device charger, they are great, they offer more rapid charge for my (android) phones that require it (can't comment on the fruity phones or devices as I don't own or use them, but I would assume the same for them). For the more nerdy types, I use one to power a 5v Bias-Tee for a small active antenna, and a fully charged bank lasts in the region of 2 or more weeks (and eliminates USB noise from SDR Bias-Tee or USB ports on computers). Comes nice packaged in a box, with brief user guide and guarantee card, a nice mesh drawstring bag, a 30 cm USB-A to USB-C cable (I assume charge only, never used them as have a set of other cables to do that job). And that's your lot. I regularly buy them on offer which makes them even more value for money. Next time I see one reduced, I'll probably add another to the collection as I really do like them. Good stuff!
