INIU Power Bank, 25000mAh 100W USB C Laptop Portable Charger, PD QC Fast Charging 3-Output Battery Pack, Travel Charger for Laptop MacBook iPad Tablet Steam Deck iPhone 16 15 14 Pro Samsung S22 etc

Every once in a while a generic brand finds their stride and eventually becomes something. This is how popular brands like Anker and Ugreen got their start. I think INIU is another one, where engineering, quality, consistency, and value have started to make them stand out.Build quality is solid. This power bank has a slim profile but feels substantial and heavy in the hand. The shell is decent quality and the LCD percentage indicator is neat. It comes with a padded yet ventilated drawstring bag which allows the battery to be protected while in use.Anker does not carry a battery in this size and capacity with the same 100W output which is what sold me this one. Their most similar option is a thick rectangular pack not that suitable for strapping to a portable gaming device. However I bought an Anker 736 100W wall charger to go with this and the two are a great combo. This battery will use up to 65W and charges relatively quickly given its large capacity. I haven't measured actual capacity but I'd wager the 25000mAh rating is pretty close to genuine.Power output is spectacular. The first USB-C port can output 100W when used by itself but drops to 65W capacity when using the other ports. When using just Port 1 + Port 2 it can output 65W+45W and Super Fast Charge a pair of smart phones from 15-20% to full in about an hour. Can confirm it allows my ROG Ally X to play in 30W boost mode, normally only accessible via the wall charger. Very impressive performance.The only weird behavior is when you try to use Port 2(USB-C) and Port 3(USB-A) at the same time. It drops the charging capacity of both ports to 15W total between the two even though other combinations allow much higher total output. Port 1(USB-C) stays at 65W minimum output no matter what. I personally would use EITHER Port 2 OR Port 3 but avoid using both together to get around this issue. However if you did have to charge 3 things at once, It will surely do that.For the money this is hard to beat. I paid less than $60. INIU is starting to be reviewed and tested and the nerd community has largely approved their products. In this case the hype hasn't let me down. Thanks Reddit!

Amazing battery bank. It keeps my Steam Deck and all my attached peripherals running (peltier cooler, 2nd screen) for hours on end while playing my emulators or even AAA games. Size is perfect for my use case and price was very competitive. Has pass through charging and the screen is bright. Problem I am facing and why I gave it a 3 star is because no matter what I do, this will NOT charge at 100w. I have used multiple 240w cables, 100w cables, and even the one that came with this and still nothing. I have tried 3 different 100w chargers and nothing. Even my 240w charger maxes out at 60w while charging. Not sure if mine is a dud but the In/Out claim of 100w is not true for me.Update: After receiving and 2nd one to test, confirmed that I will only charge at 60w. I pulled the Spec sheet and saw that it indeed charges at 65w (losses) but again, thus is an amazing product and DOES output at 100w. Charging might just take slightly longer because it only charges at 60w and not 100w. Don't even start with the size. Smallest one out there with this capacity.

I normally dont write reviews but this thing is amazing. I bought my 25000mah version over a year ago for a long trip to Japan I was taking. It turned out to be perfect for my trip as it has plenty of juice to charge up my phone at least 5 times and with the 65w usc port it had my phone charged up extremely quick. I also used it for my asus rog ally to have it play games in turbo mode and this thing game me many more hours of game play. Even after my trip this thing was so handy and fast at charging that it became my primary way to charge my devices. Unfortunately after a year the 65w port had some sore of failure and stopped working. Luckily the powerbank had a 3 year warranty and after reaching out to Inui for product support and some explaining of the issue, they sent me a replacement powerbank. This made me love this product even more knowing the company stands behind its products.

Update:They offered a replacement one without me even requesting it, so unexpectedly good customer service. Exact same problems. So I started digging out a variety of chargers and cables from the assortment I've collected since type C became a thing and tried it with a few different devices (laptop, phone, steam deck). The only things I had problems with were that one Dell charger (that just happens to be the one I use the most) and the included cable. Everything else worked as you'd expect.So: weirdly incompatible with that one charger, but worked with several others I've gotten with various phones or bought separately of different output power modes. All the other cables I tried with it worked fine both charging and discharging. So I don't know if I just got really unlucky with two defective cables included in the box or if there's something incompatible about them, but they also wouldn't be the first USB-C cables I've tossed in the trash for being flaky.But, nobody's buying this for an included cable; I bought it for the compactness and the 100W charging and all that seems to work great aside from one particular charger.Original:The size is nice but it's absurdly picky with cables. It just plain won't charge with my 65W Dell laptop charger (that works fine with every other USB PD device I own and supports 4/5 of the input modes it lists on the back), but luckily my Anker 100W charger worked was able to charge it. I tried to charge my Steam Deck with the included cable and it worked the first time, but now the charging constantly flickers on and off with the included cable. I connected it with another high quality USB cable and it seems fine for now, but the inconsistency really makes me wary about traveling with this battery.
