Auskang Slim Power Bank with Built-in Cable 2500mAh, [USB C version] The Most Lightweight Battery Bank and Thinnest Portable Phone Charger - Credit Card Size

Highly recommend this item. Its compact and easy to carry and has a built in plug, so you don't need any spare leads. I have already bought one for a friend and recommended it to others. It won't fully charge my Samsung, but it gives around 65% or more, which is enough to get you some charge for emergency use. I wouldn't want a bigger one as this is just a slimline credit card size and only slightly thicker, perfect for your purse or pocket.

So excellent! So often I used to find myself with no charger because I wouldn’t carry a bulky one around with me.This one is so thin and lightweight that it’s easy to always keep in my wallet.It may only be 2500mA but that’s much better than zero when you find yourself with a phone at 1% charge. Brilliant at what it does.

I wanted a pocketable powerbank to top up my phone's aging battery that sometimes fails to get through a full day. This powerbank gives my phone a 50% top-up which is about 5 hours of HD video watching. More than enough for my needs.The metal build quality seems excellent. I am a little worried that the built-in USB C cable may be a weak point, but there is a separate USB C socket that can be used if it fails.It's a few millimetres larger than a credit card and easily fits in my wallet.Negatives: It is a little slow to charge from a 5V wall charger (about 3 hours from 0 to 100%). It also doesn't quick charge my phone. Neither of the above is an issue for me, as I will be using it on a bus, train or in a pub at the end of the day.Don't buy this if you want it to quickly fully charge a tablet or a phone. For me, it's the perfect powerbank to get a topup until I get home to recharge. Anything bigger and heavier is overkill.

I have a Ridge wallet, so I thought it'd be great if there existed a charger exactly credit card sized that would fit seamlessly in the wallet. Although it's only a centimeter wider and thinner, it's still not "credit card sized"The actual charger itself, good for the price. The built in cable saves carrying around a spare cable, and it is still very portable.

Great slim line power pack.Sits discretely in my jacket pocket and (with the integral USB C charging lead) has come to the aid of my mobile phone on several occassions. Has a separate lead for changing.I would suggest being gentle delatching and restowing the integral charging cable (so far so good on that front)Could argue it was a little pricey compared to other power packs, but I wanted a slim / discrete unit and on that score I am happy with the overall performance / cost.

Bought as a power bank to take around with me on holiday that wasn't bulky. Absolutely amazed at the compactness. Enough to charge my phone to around 60% which is all I wanted. Metal case is good quality.

Only tested in anger a few times but it is the advertised size and weight and fits in my wallet just great. The built in wire works great but can also use an external one. Saved me a couple of times now when my phone was nearly dead and I needed directions.Don't have lab facilities to test the quoted capacity but from how much it charged my phone based on the quoted capacity of this battery and my phone battery I'd say its about right so far.

Waste of money. It did show the charging symbol for a few minutes then vanished. I used more energy myself attempting to try it 3 times before giving up. Useless.
