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

I like as it is slim enough to go in my purse with my credit cards as it is my emergency back up power. it also powers up my phone to 75% and quite fast.This is the second one i buy as the other one is a different output for my other phone.blue grey in colour, very slick.

This mini credit card sized powerbank seems really good. Small and very light it could easily fit into a pocket or handbag. I love the fact that the cable is inbuilt so there's no need to carry a separate one to charge your phone. It holds quite a lot of juice certainly enough to give my phone a good boost when out and about. It's a gorgeous pale blue colour too. I would recommend this product

Very handy but a bit fragile, not sure how long it will last.

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.

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.

Will charge an iPhone 16 from empty to 30% full so I use mine as an emergency back-up. It's awesome that it comes with it's own cable. The small battery capacity means that it has a very slim form.

Great size but only has a usc connection so wont fit my 1phone 13. Pointless!

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.
