5.0 out of 5 stars Amazing device., 31 Mar. 2013
By 
This review is from: Anker Astro2 8400mAh Dual USB Portable Charger External Battery Power Bank Pack with Built-In Flashlight for iPhone 5S, 5C, 5, 4S, iPad Air, mini, Galaxy S5, S4, S3, Note 3, Nexus 4, HTC One, One 2 (M8), Motorola Droid, MOTO X, G, and most other USB-charged devices (Apple adapters - 30 pin and lightning, not included)
I bought this as I was going skiing at at easter by coach. This is a 24 hour journey where there is no option to charge and devices. I recently sold by iPod 160gb classic as I bought a Galaxy S3 and wanted to use that as my sole media device. The battery on the S3 with constant use is abysmal, so I decided to buy the Anker to give it some extra juice.

It's 8400 mAh battery charges surprisingly quickly, but it does not come with a plug adapter so you will need to charge it off a USB port or have a usb-plug socket. During the journey the juice pack was able to keep my S3 alive whilst watching films and listening to music constantly. As it has dual charge functionality, it also did the same for my friends iPhone 4S and my FiiO E17 Alpen.

All of this used approximately half its charge, so it managed the same level of performance on the return journey without a recharge.

This is an excellent device for long journeys where your devices will die if not charged and you will not be disappointed. I have started carrying it with me everywhere to ensure that my phone never runs out of battery.

It comes with all the cables you need, as well as a variety of attachments and a useful carry bag that.
