Power Bank 6000mAh, COOLREALL Portable Charger External Battery for iPhone,iPad,Samsung Galaxy,Android,Smartphones,Tablets etc (Black) [Upgraded Version]

I bought this for my 14 year old as whose phone is constantly running on empty. It arrived really quickly and is so easy to use, just a little streamline black rectangle that she slips in her pocket with her phone and is good to go.. She is using it all the time so it must be good and her "street cred" has not been damaged. All I know is I can always get her, her phone always has power. It does exactly what I need it to do. Very happy.

A great pocket or handbag portable power bank, at a reasonable price, charges quite quick compared to others of this capacity I've bought. It has 4 LEDs to show how much charge it has. I bought 2 and I'm really pleased with them, I'll be looking to get some more for Xmas gifts.

Very small storage charge. Already half storage used and phone only on 33%. Handy, slim and easy to use as an emergency charge but useless if you need to fully charge your phone due to lack of access to mains electricity for an extended period - spend a bit more for a decent portable charger if this is the case.

Great sleek design good for a night out of you have an apple device tho. Get a small charging wire with it. I find best that a little electrical tape to hold the wire with the device works best so that it doesn’t get lost. But the product itself is perfect

Aptly named, this is a cool piece of equipment and ideal for keeping a charge whilst on the move. Sellers give an exemplary service.

Does what it says on the box it's a fantastic power bar and the good thing is you can charge two devices at once where is fantastic on my Android phone and also my Android tablet

Ideal for travelling, unfortunately the cable broke so now having to use another cable.

Bought as a gift for a relative who says they have often confused it for their mobile but love that the shape and size makes it easier to put in their pocket etc
