Android phones, apps and tablets

I've used all sorts of battery packs and that's probably my favourite....but bulky though. My evryday one is this EasyAcc® iChoc 5000mAh 2.5A Dual Port Fast Charging Ultra-Slim PowerBank built-in Micro-USB Cable and LED Flashlight Portable External Battery Charger Pack for iPhone 5S 5C 4S (Apple adapters not included), Andorid Smartphone, Tablets, Bluetooth Speakers headset, Google Glass, Gopro and other devices - Matte Black: Amazon.co.uk: Computers & Accessories
Handy cos its quite a bit slimmer and the microUSB cable is built in......much lower capacity tho... ya pays yer money......

Sweet.

Cheers.

Do you use this with a phone or tablet?
