The Griffin TuneJuice 2 Back-up Battery for iPhone is a battery charger for iPhone or iPad touch (or traditional iPds) that, instead of being rechargeable, uses AAA batteries. That means to use of the TuneJuice you do not have to constantly find an outlet and make sure you recharge it before your iPhone. You can just throw in fresh batteries and get going. So if you are traveling for a long period of time and worry that you may need to keep a few items charged then this is the charger for you.

Griffin TuneJuice 2  Back-up Battery for iPhone - accessory review

The Griffin TuneJuice 2 is made to give you power when you will be without an outlet for a extended period of time. If you are planning a camping trip but still want to have your iPhone working throughout, and don't mind packing a bunch of AAA batteries, this is perfect.

The main unit slides open to allow you to insert the batteries then you just plug the 30 pin connector to your iPhone or iPod. I do find the 30 pin connector a bit odd. It's long enough to be in the way but not long enough to be able to keep the TuneJuice in your pocket or purse and use your iPhone while charging. If anyone knows how this short cord is helpful let me know in the comments!

In terms of power the Griffin TuneJuice for your iPhone will give you up to 14 additional hours of audio and up to 2 hours of additional video play. I was hoping that it would give me more power but to get that you need to carry extra batteries with you.

The Griffin TuneJuice 2 Back-up Battery for iPhone is available from the TiPb iPhone accessory store.
