Mophie has introduced a redesigned version of their lightweight Juice Pack Air case battery for the iPhone 4, available for $79.95 from the Apple online store. This new version adds only a few minor tweaks from its predecessor, mainly an open top design for better accessibility to the iPhone’s headphone port, as well as a “bottom cap” snap design to allow for the iPhone 4 to be docked while still in the case.
The Juice Pack Air is one of the more popular iPhone 4 battery cases, mainly because it’s one of the smaller and lighter battery solutions for the iPhone. Mophie’s press release says the new Juice Pack Air maintains the 1500mAh rechargeable lithium polymer battery available in the previous iteration, which adds up to 6 hours of 3G talk time, 36 hours of audio playback, and 9 hours of video playback.
Other nice touches are 4 LED lights that indicate the battery’s status, a pass-through USB that lets you charge the Air’s battery and sync your iPhone at the same time, and a standby/charging switch so you only use the Air’s battery when you need it.
