Mophie Juice Pack Air (for iPhone 4/4S): The Mophie Juice Pack Air combines
a protective case and rechargeable battery for your Apple iPhone 4 or 4S. The
Juice Pack Air has a built-in rechargeable battery which extends the battery
life of your iPhone 4/4S for hours. The Juice Pack Air also provides a
comfortable ergonomic design with the complete protection of a
hard shell case with protective rubberized backing. With the Juice Pack Air,
you'll be able to easily access all of your controls, microphone, speaker, camera, and
headphone jack. It also has acoustic sound enhancing speaker ports for a richer,
fuller sound quality.
Note: You will need to remove your iPhone 4/4S device from
the Mophie Juice Pack Air in order to connect your iPhone 4/4S with an
Apple certified product with a 30-pin dock connector. You will also need to
remove your iPhone 4/4S from the Juice Pack Air to connect your iPhone 4/4S
to a home audio or car stereo component which allows iPhone playback through
its USB port.
Extended Battery Life: Since it is designed to almost
double the battery life of your iPhone 4/4S, the Mophie Juice Pack Air is the
ultimate iPhone 4/4S battery case for travel or business. The Juice Pack Air is
great for when your iPhone 4/4S is drained of power or you simply one to extend
its battery. When the iPhone 4/4S is connected to the Juice Pack Air, a battery
symbol will appear on the screen and you will hear a chirp from the iPhone 4/4S;
this indicates that the iPhone 4/4S is charging and/or using the power from the
Juice Pack Air rather than from the iPhone 4/4S itself.

Rechargeable Battery: The Mophie Juice Pack Air features a
rechargeable lithium-polymer battery rated at 1800mAh. The Mophie Juic Pack Air battery can easily be recharged by connecting the Juice Pack Air to a
power source using the included micro-USB cable. The USB cable can be plugged in
to your computer or any "Works with iPhone" wall-plug style power source with
USB output. You can either charge the Juice Pack Air with the iPhone 4/4S
inserted or charge them separately. The Juice Pack Air comes charged and ready
to go, but after the initial use, normal charging will take only 2 to 3 hours
for maximum power.
Note: The Juice Pack Air is rechargeable for over 500 full
cycles. So, you can charge your juice pack 10% of the way 10x before it
counts as a complete cycle. After 500 cycles, its fully charged capacity
will be less than 75% of the capacity when it's new.
iTunes Sync Compatible: You can sync your iPhone 4/4S to
iTunes without removing it from its Mophie Juice Pack Air via the included
micro-USB cable. The Juice Pack Air will also charge while connected to your
computer and syncing with iTunes.

the Juice Pack Air in standby mode, so you only use the battery when you need
it. In standby mode, the Juice Pack Air still allows charge and sync
capabilities through the micro-USB port and still offers the complete protection
of a case.

keep tabs on how much power is left in the Juice Pack Air battery. The LEDs
also keep you updated on the Juice Pack Air charging status when it's plugged

Juice Pack Air becomes more charged, the LEDs will indicate how full it is, but
one LED will remain blinking until completely full. To check the battery status
of the Juice Pack Air, press the button located on the bottom of the case. When
pressed, the LED lights will illuminate for several seconds. Four LEDs means
