Compact, Powerful, and Charges Fast!
I’m really impressed with this INIU 20000mAh power bank. Despite its high capacity, it’s surprisingly small and lightweight — perfect for travel, work, or everyday use. It charges my phone multiple times and still has power left over. The fast-charging feature works brilliantly — my phone and tablet both charge quickly, and I love that it has both USB-C input and output. The digital display showing the battery percentage is a great touch, so I always know how much charge is left. Overall, this is one of the best power banks I’ve owned. Reliable, sleek, and efficient — absolutely worth the price!

Well built product
First impressions: • Product looks well built. • Compact for a 20000 mAh capacity, but not enough to carry around with me daily. • Convenient LED which could possibly help in very unique circumstances. I would recommend this product.

Bank it , use it !!¡
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 .

Chunky!
It’s larger than shown in the picture and has more weight than expected, that being said, it’s one of the better power banks I have purchased.

Great battery bank
Powerful, well made high quality battery bank , I bought it to extend my 360 camera batteries and charge my drones if I'm out in the field . It will recharge 3 , 360 batteries twice over thats 6 hours of total fixing time . Or recharge my Potensic Atom 2 batteries once thats an extra 75 mins of flight time more than enough for any adventure.

Not as small as it looks…
Small-ish physical size but quite weighty. Thought it would be smaller from the pictures. Works well nonetheless.

Very happy with this, slightly larger than the picture would suggest but not an issue, very rarely needs to be charged, can charge my phone 4-5 times before it needs a charge and fast charging also, would highly recommend

All good but no USB A connection cable

Just the best power bank I’ve ever used. Travelling recently through multiple zones that used differing electrical sockets I brought a bag of cables and adapters, none of which I needed, just a USB-c outlet to charge power bank and two cables for my devices. The display showing remaining power percentage is very useful as is the cleverly designed lanyard cum USB-c cable.

Not the lightest but great bang for buck. Bringing it on the Tour de Mont Blanc this week so it will keep my devices charged and ready to go!
