More than enough to keep my devices powered for a day.

ELJanuary 3, 2026

Very nice battery bank. Feels solid and durable. Love the large display showing the battery percentage. Can fast charge my Samsung Galaxy s23 ultra several times and run my heated vest for hours. Also love the built-in cable for those occasions where I forget to bring a longer charging cable. Will definitely consider getting another one for my daughter in college. Read more

Excellent portable charger.

PhuongNovember 25, 2025

I really couldn't ask for more at the price I got it at, especially with all the features it has. It has quick charging output, small size, built in USB-C cable that sorta acts like a loop handle, display with percentage of battery life, and a small LED flashlight you might use once in a blue moon. Build quality and design seems great and doesn't feel cheap in the hand. Since I haven't bother to upgrade all the charging bricks at home, this portable charger is technically the fastest phone charger I have, and it seems to hit close to the rated 45W charging speeds. I'm hoping it lasts a long time. Read more

Size and Performance are Awesome

Tony de DCNovember 21, 2025

This charger is awesome! It's compact and rapid charges my Galaxy s25plus. Charging from almost zero to full was as quick as plugging into an outlet and only used 15% of the chargers capacity. I'm still a little on the fence on whether the best cable option is built in (as this one is) or attached via lanyard (i.e., attach or not), but so far very satisfied with this purchase. Read more

★★★★☆

Good quality and performance.

Gary KessieDecember 28, 2025

This portable charger works well, and is very convenient when traveling. It charges cell phones quicker than plug in wall chargers. Read more

Great little charger

Todd D.November 15, 2025

Love the smaller size with a good amount of charging power. I like the attached USB C cable that can be used to charge my cell and to recharge the battery pack. Has a nice clear display of of much charge it has available. This is my 2nd INIU portable charger and I like their quality. Read more

Great High-Capacity Battery

Wolly BoyDecember 1, 2025

So far, so good. I love the look and size. The charger delivers as promised. Only thing I would warn about is the weight of the battery. The 20000mAh certainly adds some heft that other 10000mAh batteries don’t have. Read more

Quality Battery Pack

Mark MandelstammDecember 27, 2025

Quality battery pack. Fast to charge phone and it lasts. It's powerful and meets 2026 standards for the airlines. Read more

Quit researching and GO GET THIS!

DottieOctober 20, 2025

This is my first ever review on Amazon, but this product deserves it. I've used it on two devices: 1. My Samsung S25 Ultra, and it charged from 0 to 100% in about an hour and still had 66% battery left and 2. My EarFun Pro 4 Buds case - It charged from dead to full in about an hour, and there was still 97% left on the charger. My point, it charged the case slowly, as it should, so the smart chip is working but only used 3% capacity. It charged the Smartphone fast, as it should, and only used 33% capacity. I've bought many different power banks and returned most of them. This one I will keep. Also, the integrated cord seems very stable, although I would have liked it to be flush with the unit as it makes a big loop so that you can carry it around; which I guess is good since it doesn't have a case but that's just me. It also has pass-through in that it charges itself and a device if you like. When I researched power-banks, INIU seemed to have these on most of theirs and at the highest level of quality. Read more
