Dual USB Output Super Slim Power Bank Ultra Thin, 3000mAh Portable Charger Mini External Phone Battery Pack Small Dual Outlet, Emergency Phone Power Backup (White)

Quick delivery. Ready for use quickly. Small and light weight. I now have three of these little helpers. One for the purse, another in the drawer next to my recliner. The third in case a friend needs to use one when we're out and about. Real space savers. And I love them all.

Appears to provide power at the rated 3000mAh capacity. The light weight is it's biggest advantage. The second charge didn't work overnight however, but after unplugging and plugging it back in, it charged fine.

I love the size, and it worked great - until all of a sudden it didn't. I used it about 5 times, and now it won't work at all. I depend on having a (working) battery during live events, and this one left me in a bind when it all of a sudden wouldn't work. So disappointed!

This is the perfect size to make a NeoGeo mini truly portable. I used this, some hook and loop tape, and a very small (I think 4 in) USB-C to USB-A cable to turn my NeoGeo mini to a cute portable desktop arcade cabinet! I was a bit worried about the charge capacity at first, but to be honest I've been playing it off and on for days now with no need to recharge. I haven't done any massively long gaming sessions, but it's been perfect to allow me to put my NeoGeo Mini on my desk and occasionally pick it up to play a game of Metal Slug.

I have updated this from my previous 5-star review. We didn't travel for most of 2yrs during pandemic... now travels commence and I went to charge these up... I bought two and neither will take a charge now. It is 2.5yrs since I purchased and the 1yr warranty is over. I contacted the vendor/mfg and they say as the warranty is over there is nothing they can do. Now they go to the landfill. I would certainly expect them to last more than this, esp given they have probably had less than 50 cycles. The brand still sells these and similar ones, but I won't buy from them. Original Review: I got this for my wife to take on a 1mo trip to Asia. We use our phones a lot and run thru a full charge by mid-day. This lets us keep full. I have it with an iphone 7 and just keep it in a bag charging with a stubby cord when not in use. Its slow charge (1A) so dont expect the fast charging of the big boys, but it is super light - lightest I found in the 3-5000mAH. Only a couple weeks use so far so will see how it holds up, but so far very happy. esp with having a USB-C output (would be nice if that was in/out) with some GaN/PD support, but thats asking a lot.

I did return this item, but only because its dimensions didn't work for me. It's ability to charge and work with other devices was indeed handy. If the dimensions work for you, then have no worries using this item.

I purchased 3 of these a year ago and find the size and shape really useful. They fit neatly behind my iPhone when I am walking around and are light enough that I can keep a spare one in my pocket without any bulk. I found that in the end I hardly ever plugged my phone into an outlet after I had these because I kept leaving it behind when I wandered off! So they have been heavily used for a year. Recently, I noticed they weren't delivering as much charge as before so I decided to replace them. In the 2022 model the C port was only an input, but in the 2023 version it is both input and output so that is an improvement. I also use them with the Galvanox Ultra Slim wall charger and they work very well together: www.amazon.com/gp/product/B097F5JJ56.

Plus: Compact form factor Minuses: limited capacity, slow to charge your phone, uses micro usb to get charged
