Vida IT vCard+ Ultra Slim Power Bank 4000mAh Mobile Phone Portable Charger Small Rechargeable Flat Battery Pack for iPhone Samsung Android USB C with Built-In Cable Thin Pocket Size 8mm (Black)

Really impressed with my purchase - Vida Ultra Slim Power Bank 4000mAh, it’s size is ideal and comfortable fitting into my pocket and it’s not heavy, the charging time for my iPhone 6s, yes it’s an old one, from flat battery is very quick and recharging the power bank also reasonably quick, can’t probity either times, but very acceptable. It’s a quality product, can strongly recommend.

Great product for recharging a mobilePhone or Kindle fitsIn a small Bag handy for travelling

Does what it's supposed to do and does it well. Recommended.

I already own 3 of these and they were pretty cool. However I just ordered 2 more and both came puffed up and would spin if set on a flat surface. You could actually squeeze them easily. Where as the old ones were solid and flat. Didnt seem safe.

Very convenient size, easy to use. I've been able to recharge my earbuds and my phone, and there's still a little battery left. It charges quickly. It's the size of a credit card and about half a centimeter thick.

Sturdy and easy to us. Extra connectors for idevices and usb.

This is so slim and easy to travel with. I am regularly picking it up as I leave the house realising I am low on battery and it ensures it lasts the night. Good capacity and easily keeps my phone well-charged when out and about. Super slim so it isn't uncomfortable to carry in a pocket and easy to hold when charging and using my phone. Highly recommend for the price.

small in size and easy to carry but it's very slow in charging and it only charges my Samsung phone to max 65% from 15%. It's good to survive till you get home especially it's super thing and light.
