Auskang Slim Portable Charger with Built in Cable - Ultra Thin Power Bank Compatible with iPhone 15 Series Samsung Galaxy/Note Google Pixel and Other Android USB-C Smartphones

Fantastic. I keep these are the back pocket of my jeans (or suit), and sit on it all day. The charger has not bent, or suffered any harm in functionality. I'll throw a charge on this once a week just to make sure I've got power, it charges quickly, and you have the fantastic size and built-in cords to make this a fantastic charger they have on hand! Highly recommended.

Absolutely everything is on my iPhone, so if I run a flat battery I’m potentially in a lot of trouble. After a lot of research and trying a variety of batteries, I found this one to be the best for use in an emergency. Its dimensions, and particularly its thickness and weight, let me carry it on me all the time. Its capacity of 3,500 mWh is more than enough for use in an emergency in my daily, urban life. I tried the size one larger than this that had a 5,000 mWh capacity, and found that the extra size, extra thickness, although tiny, and extra weight, although only 30 g, was unbearable for every day carry. The built-in Lightning charging cable works perfectly, and the device has a second port which both recharges and delivers power by USB-C, which was a nice surprise, ensuring longevity and utility.

I am impressed with this. The 5000mAh version is listed as the newer version available however I bought that and it was a lot heavier and thicker that you would expect for just 1500mAh more, so if you are debating which to get - go with this 3500mAh version. I use it placed behind my phone to keep my phone powered and its easy to hold both in the hand. Galaxy s20 and onward have a feature allowing 85% max charge only and the phone pauses charging at that point and will draw power from whatever is plugged in, allowing the battery to not be depleted or even get a trickle charged, so it expands the life of your galaxy battery since it's not being used! This powerbank is perfect if you want to do that much of the day as it can just tag along behind it and last hours powering your phone while the galaxy phone just stays at 85%. even rubber band it if you wish, or placed in your pocket with the powerbank behind it. It also fits in my trifold wallet, it's wider than a credit card but sits fine in the center most fold area of the wallet that hold cash. It's an adorable little power bank and is built solid, very lightweight.

I bought this for my iPhone 11 as it could no longer get me through the day. I wanted a powerbank that I could attach to my phone (to stop it sliding around) whilst NOT charging wirelessly. This was perfect, it is impressively thin but still provides 5000mah and can gets me from <10% up to ~85%. The integrated cable was also essential in order to use everyday. The shape is perfect as it is the exact same width as my iPhone 11 (and most other recent iPhones). In order to make it more functional, I added a ESR ring and circular magnet to either side of the powerbank. This allows me to attach it to my iPhone when in use (there is also a ring stuck to my iPhone) and to my ESR card wallet when not in use. Really impressed with the slim size of this powerbank and can really recommend it as a pocketable option for daily carry.

great size and looks well made. Have not found that it does a full charge on my phone though which was the whole point of carrying one in your handbag. but good size and weight and looks quality.
