Item # 833JPPI4B | MFR # 1160_JPP-IP4-BLK
This item is no longer available.
The juice pack plus has openings for your iPhone's camera lens and pass-through control buttons along the sides.
Whether you're traveling across country or just spending the day running around town, you want your iPhone to keep going as long as you do. And if its battery runs down when there's no outlet near? Not a problem with the mophie juice pack plus. This protective case features a built-in battery with enough power to keep your iPhone 4 or iPhone 4S going for hours after its battery has run out.
Slip your iPhone onto the juice pack plus' 30-pin connector and close the case. It's now connected to a built-in rechargeable battery that can double your reserve of power. That's enough for 8 additional hours of talk or Internet use, or up to 44 more hours of audio playback. You can set the juice pack air to keep your iPhone continuously charged, or with a button press recharge your iPhone quickly when you need it.
The juice pack plus has a USB charging cable that can connect to a computer or USB-compatible power adapter. And good news — you can sync your iPhone through the air's charging cable. Integrated pass-through buttons let you control volume, mute, and power on/off. An included adapter lets you plug your headphones into your device through the case.
Mophie Juice Pack Plus (for iPhone 4/4S): The Mophie Juice Pack Plus combines a protective case and rechargeable battery for your Apple iPhone 4 or 4S. The Juice Pack Plus has a built-in rechargeable battery which extends the battery life of your iPhone 4/4S for hours. The Juice Pack Plus also provides a comfortable ergonomic design with the complete protection of a dual-injected hard shell case with protective rubberized band. With the Juice Pack Plus, 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 Plus 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 Plus 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 more than double the battery life of your iPhone 4/4S, the Mophie Juice Pack Plus is the ultimate iPhone 4/4S battery case for travel or business. The Juice Pack Plus 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 Plus, 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 Plus rather than from the iPhone 4/4S itself.
Note: If your iPhone 4/4S is drained of power, the Juice Pack Plus will first charge your iPhone 4/4S. If your iPhone 4/4S is fully charged, the Juice Pack Plus will act as your primary battery and no power will be lost from the iPhone internal battery until the juice pack is depleted
Rechargeable Battery: The Mophie Juice Pack Plus features a rechargeable lithium-polymer battery rated at 2000mAh. The Mophie Juice Pack Plus battery can easily be recharged by connecting the Juice Pack Plus 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 Plus with the iPhone 4/4S inserted or charge them separately. The Juice Pack Plus 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 Plus 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.
Standby Mode: The integrated power switch allows you to put the Juice Pack Plus in standby mode, so you only use the battery when you need it. In standby mode, the Juice Pack Plus still allows charge and sync capabilities through the micro-USB port and still offers the complete protection of a case.
4 LEDs: Four LEDs on the bottom of the smart battery case keep tabs on how much power is left in the Juice Pack Plus battery. The LEDs also keep you updated on the Juice Pack Plus charging status when it's plugged in. The LEDs located on the back of the device will blink when charging. As the Juice Pack Plus 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 Plus, press the button located on the bottom of the case. When pressed, the LED lights will illuminate for several seconds. Four LEDs means that the Juice Pack Plus is fully charged, and one LED means that it is almost empty.
Protection Circuitry: The Mophie Juice Pack Plus features built-in short circuit, over-charge, and temperature protection.
