The Best Samsung Galaxy S3 External Battery Juice Packs

An external battery will get your S3 through busy days and long road trips without that sudden fading of the light...

The S3 comes with a Li-Ion 2100 mAh (milliAmp hour) battery which gives you hundreds of hours of standby time and around 20 hours of 2G surfing or 10 hours of 3G.

The battery will drain pretty quickly, though, as soon as you start playing games or watching movies.

To recharge on the move you will need something like a 5000 mAh external battery recharger to get a flat battery back to full charge.

A 10000 mAh device should charge your phone two or three times and get you through a full weekend without needing to plug into a wall or car charger.

Powergen 5200 mAh Charger

Powerden chargers are tough, well built back-up batteries that will stand up well to some jostling in a bag or pocket.They will charge plenty of different devices including iPods and other smartphones.

The iPhone 4 can be charged twice with its smaller battery. The S3 can be charged fully once with some juice left over

There is a useful collection of tips to mate with various gadgets and indicator lights to let you know what is happening as you juice up.

Dual USB ports

For a little more power (and a little more bulk to carry around) you could try the 8400 mAh juice pack.

This is bigger but flatter and more pocket friendly.

10,000 mAh Charger from Anker

The Anker Astro 3 is a pretty big device- bigger than the Samsung Galaxy S3- and you will only need something this big if you are wanting to charge your phone two or three times. Or you have a tablet you want to juice up sometimes. It will charge an iPad or Galaxy tablet from flat to full charge which is impressive!

The 3 USB ports each deliver twice the power of smaller external batteries and the 2A output means a faster recharge.

The range of tips is bewildering (around 12). You could probably recharge the cat if you run out of food!

If you are already carrying a backpack or messenger bag as part of normal life this can be a very useful device. It is not so pocket friendly as the devices above.

New Trent 12,000 mAh Juice Pack

New Trent make all sizes of battery packs but this brute deserves a special mention.12,000 mAh makes it one of the biggest on the market.

The rounded edges make it less likely to damage other devices and it feels tough (though maybe not as tough as the powegen models).

It has dual USB ports and should charge your S3 three times. The 2A output makes it fast.

It comes with a heavier price tag than comparable models but the New Trent name is pretty much a guarantee of reliability.
