Regardless of the fact those Apple products are made with some of the best batteries on the market. Even the most conservative iPhone 4 user is going to have a day that pushes the limits of his phone’s built-in 1420 mAh battery.
Mophie has outed its new Juice Pack Plus battery case for the iPhone 4. Like the prior Juice Pack Air for iPhone 4, the Plus integrates a rechargeable battery—2000 mAh—into a two-piece, slide-on case with open access to the headphone port, cameras + flash, volume buttons, ring/silent switch, and sleep/wake buttons.
The same company that launched an iPhone-based credit card processing system earlier this year — adds an additional 2000 mAh battery within its shell, bringing the total onboard power to 3420 mAh and extending iPhone 4 use times by a large margin. Mophie claims the new Juice Pack Plus offers up to eight hours of additional talk time over 3G, up to seven hours of 3G data use, up to 44 extra hours of audio playback, or up to 11 hours of extended video playback on a single charge.
Other features include a standby/charging switch, integrated LED status indicator, acoustic sound enhancement, and a micro USB port for charging and syncing.
It’s available now in black with yellow, Engadget Mobile magenta, and classic Engadget cyan coming soon. The Mophie Juice Pack Plus is one iPhone 4 case that’s actually worth its $100 price tag.
