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.

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.

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.

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

At slight bigger than a credit card and not hugely thicker than maybe three or four together, it fits comfortably in my wallet and is very useful for an emergency/get you through the last few hours of the day, backup power source. It wont fill a modern iPhone but for maybe 50% (at a guess) it does the job. And finally the inbuilt USBC cable is great. There are wireless chargers available but they cost quite lot more and are thicker.

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.

Don't bother wasting your money on this doesn't charge phone or keep charge with it plugged in

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

El cable no me inspira la más mínima confianza, es finísimo. Por otra parte se calienta con la mirada. Devuelto.

La compré como una prueba pensando que no iba a servir por ser tan delgada y me ha sorprendido. No da mas que para una carga, pero es suficiente, pues con lo delgada que es se puede llevar fácilmente en el bolsillo donde va la carter

This is a perfect powerbank to keep in a bag for a daily commute to work. It is very light weight and I have a used it a few times when my mobile phone was too close to the lower limit of charge. It doesn't charge the phone all the way to full, but it gets it to a decent level so I could keep going until reaching a charger. So, a life saver.

Super batterie externe ! Encore plus fine et légère que ce que je pensais ! C'est une pépite

Je cherchais une batterie de secours à emporter partout avec moi, en alternative à des batteries plus lourdes pour d autres occasions planifiées. Ce modèle est léger, compact, pratique, il passe partout ( poche, sac banane, portefeuille..) et permet une recharge de mon téléphone.
