Which one should I get, what is the main difference between the Juice Pack and the Juice pack air? Anybody that has one of them can you please explain this to me? Thanks http://www.mophie.com/ you will find them both. Thanks
The juice pack air is thinner, but cannot store as much power. The standard juice pack is fatter, but can store more power. So what do you want more? A thinner battery or one that can store more power. That's what it comes down to.
The JuicePack Air has a smaller battery (1100mAh) but is also slimmer and lighter than its predecessor, and protects the whole iPhone, unlike the original JuicePack, which does have a larger battery (1800mAh) but is bulkier and only protects the bottom, the lower 1/3rd of the sides, and most of the back. I have the Air and it rocks. Just don't use it in conjunction with a full body protector (InvisibleShield et al.); you can still use a screen protector, just nothing for the back. You don't really need it though. My only complaint about the JuicePack Air is that it comes with a really short (3ft) micro USB cable. I had to go buy a longer cable for where I wanted to put it. It's also a bit hard to remove from the case. Fortunately you'll probably never need to remove it; it automatically charges and syncs right in the case. (No need to press a passthrough button or anything, it's all automatic)
