VERY EXCELLENT POWER BANK.
The Power bank is so powerful, it charges my Android phone from 10% to 100% 3 times before it went off. It’s as well a very fast charger.Is the best 👌 power 🔋 bank I have ever used.

INIU Power Bank
Looks very nice, compact and able. Yet to try out, if does what it’s claims it can I shall give it another Star. I was wondering whether a USB C Cable was missing, according to the What’s in the box description. (See image).

heavy duty power bank
I’m a big fan of INIU products. This power bank model has double the size battery capacity 20000mAh, which allows me to charge my power hungry iPhone 17 pro up to 4 times. It is small, however weighs quite a bit. But I know it would be reliable for all day outings.The powerbank came pre charged. I tested with my phone at 17% battery. The powerful 45W fast charge my phone and within the hour went to 100%.It is a robust powerbank, with a built in USB C to USBC cable. There is an additional USB A and USB C port to charge other devices. There is a large screen with bright LED light to show the percentage of battery in the powerbank. It is compatible with many devices iphones, andriods, tablets and more.

Not Capable of Charging at 45W
Update on 24.11.2025Iniu Customer Service was very helpful and arranged for collecting the power bank and sending me a replacement which arrived today 24.11.2025.After charging it to 100% level, I tested the new power bank but the same problem with the previous item happened. It stopped charging the laptop when the power bank reached its 53% level.Therefore, it seems that this is an inherent characteristic of this model of Iniu power bank and it is the same as its 22.5W version. It is not suitable for charging devices which require 35W to 45W (sometimes it can charge up to 37-38W). It is more suitable for mobiles and tablets rather than a laptop which requires between 35W to 45W.Another issue with this power bank is that after the 50% level of its capacity, it drains very quickly.Update on 19.11.2025Iniu got back to me within 24 hours of writing to them which is a reasonable time to respond and assured me that they were happy to send a replacement but recommended some measures such as using different charging cables or chargers which I had done before writing to them.After writing this review I encountered another problem which was very slow back charging the power bank despite trying two different high-speed chargers and cables (one at 240W and the other at 100W charging speed), as it took about 7 hours to charge the powerbank while for the bigger version of the same brand which has a capacity of 27,000 mAh, it takes only about two hours to charge.I am monitoring performance of this small but hefty power bank and will update this review accordingly.I bought this powerbank as I have the bigger size This powerbank is small which is why I bought it but it is supposed to charge up to 45W while in practice this was only possible when the powerbank was at 75% to 100% of the device power capacity. When it drops below 75% it stops charging a laptop which requires 35W to 45W charging speed.I tried the charging my laptop with the built-in cable fitted on the powerbank and two high speed cables which can charge up to 100W but the result was the same.It can charge other devices such as mobiles and tablets at 75% and below this level but this is not helpful if you want to buy tgis powerbank for charging devices which require 25W or more.I also tried charging a tablet and an iPhone 14 Max Pro mobile and the charging speed was up to 6.7W for the mobile which has a chargd of 66%. I repeated the test with the same cable and mobile but with the bigger Iniu 140W powerbank while connected to a laptop and the charging speed increased to 11W to the iPhone while the bigger powerbank continued charging the laptop without a fail.Due to these issues I have contacted the seller to send me a replacement to see if the replacement device can have a better performance and will updatd this review after receipt of the replacement and testing it.
