Mophie's Juice Pack Helium for iPhone 5 now available for pre-order

Looking for the perfect Valentine's Day gift for that iPhone 5-toting sweetheart of yours? The long-awaited Mophie battery case for iPhone 5 is now available for pre-order, and if you're really lucky you might have one by February 14.

The Mophie Juice Pack Helium will cost $79.95, the same as the Juice Pack Air. Everyone on the TUAW staff could have used one of these last week at Macworld/iWorld 2013, since it adds a 1,500 mAh battery to the iPhone 5 yet is 13 percent thinner than previous Juice Packs. As with previous models, Mophie's design features forward-ported acoustics so you can easily hear music from your speakers, a standby switch and an LED power indicator.

The Juice Pack Helium comes in two colors -- a nice, dark metallic and a light metallic silver. There's no word on whether the company will eventually offer the eye-catching red metallic case that is the star of the Juice Pack Air family.

That extra 1,500 mAh of battery capacity will give your iPhone 5 another six hours of voice and data on a 3G or LTE network, an additional seven hours of internet on a WiFi network, up to seven more hours of video playback, and up to 30 more hours of music playback.

As soon as the Juice Pack Helium (lighter than Air, get it?) arrives, we'll run it through a full review. In the meantime, here's a nice promotion video for you to replay incessantly.
