Poweradd Pilot 4GS 12,000mAh Portable Charger External Battery with High-Speed Output 3A+3A Compatible for iPhone,iPad, Samsung, most other Phones and Tablets - Silver

My niece has found this invaluable to keep her iPhone charged when she is out and about.It’s a decent looking device too.

The best thing i have purchased from Amazon. 3 of my friends have bought one subsequently. Great for charging handsets and get an average of 4 charges. One down side is that the battery runs down alot quicker if charger 2 devices at once

Git for our teenage son, it's the right colour, size and everything do good all round, holds a good charge, charges more than one device at a time and does it well.

This is ok but not as advertised,doesn’t give a full charge for my iPhone.Much heavier than I expected,not suitable for in pocket transportation.

Great

Heavier than the Mophie Juice Pack & more vulnerable, but having 2 outlets is handy. Charged with standard Apple lead, another advantage.

Great, works well so far.

Great little power brick had a little problem with the first one but costumer sevice was second to none and sorted it straight away. Would recommend to anyone looking for a slim power brick. 5 STARS
