mophie juice pack pro iphone 4/4s

A rugged outdoor companion

Whether you're hitting the slopes, doing some climbing, working on a construction site, or even taking a long hike, it's not enough to just protect your iPhone from bumps, moisture and scrapes. If you want to use that iPhone, you'll need to keep it powered even when there isn't an outlet anywhere around. The rugged mophie juice pack PRO was designed to withstand the hazards of the great outdoors — and its built-in battery means you'll have a ready reserve of power while you're out there.

Military-grade durability

You might say the juice pack PRO is built like a tank. After all, it does have an MIL-STD 810G rating — which means it exceeds the U.S. military's standards for impact protection and dust or sand penetration. The case features a rubber sheath that makes it vibration and shock resistant, as well as water-resistant. A rigid outer casing keeps your iPhone sealed up and safe.

Double your iPhone's battery life

Push your iPhone onto the built-in 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 up to 9 additional hours of talk or Internet use, or up to 50 more hours of audio playback. You can set the juice pack PRO to keep your iPhone continuously charged, or with a button press recharge your iPhone quickly when you need it.

An all-access case

The juice pack PRO has a USB charging cable that can connect to a computer or USB-compatible power adapter. And you can sync your iPhone through the charging cable. Buttons built into the case let you control volume and muting and turn your iPhone on and off. And you can plug in your headphones right through the case.

Mophie Juice Pack Pro: The Mophie Juice Pack Pro combines an ultra-rugged protective case and rechargeable battery for your Apple iPhone 4 or 4S. The Juice Pack Pro features an impact resistant design that exceeds military specifications (MIL-STD 810G), a built-in 2500mAh capacity battery, and an included belt clip to keep it securely on your hip. With the Juice Pack Pro, you'll still 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 Pro 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 Pro to connect your iPhone 4/4S to a home audio or car stereo component which allows iPhone playback through its USB port.

Ultra-Rugged Design: The Mophie Juice pack Pro provides you with the confidence that you can take your iPhone 4/4S with you, almost anywhere. The Juice Pack Pro has been tested to exceed the standards for impact protection and dust/sand penetration set forth by the United States Military (MIL-STD 810G). This ultra-rugged case features water-tight ports and speaker covers, a rubberized outer cover w/ pass-through buttons, integrated screen and camera protectors, as well a durable belt-clip. Military spec protection includes:

  • Splash & Rain Protection
  • Sand & Dust Protection
  • Impact & Drop Protection
  • Vibration & Shock Protection
Note: While the Juice Pack Pro can stand up to a little rain, it is not waterproof so don't take it swimming.

Extended Battery Life: Since it is designed to more than double the battery life  of your iPhone 4/4S (up to 150% extra battery life), the Mophie Juice Pack Pro is the ultimate iPhone 4/4S battery case for travel or business. The Juice Pack Pro 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 Pro, 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 Pro rather than from the iPhone 4/4S itself.

Rechargeable Battery: The Mophie Juice Pack Pro features a rechargeable lithium-polymer battery rated at 2500mAh. The Mophie Juice Pack Pro battery can easily be recharged by connecting the Juice Pack Pro 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 Pro with the iPhone 4/4S inserted or charge them separately. The Juice Pack Pro comes charged and ready to go, but after the initial use, normal charging will take only 2.5 to 3.5 hours for maximum power.

Note: The Juice Pack Pro 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 Pro in standby mode, so you only use the battery when you need it. In standby mode, the Juice Pack Pro 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 Pro battery. The LEDs also keep you updated on the Juice Pack Pro charging status when it's plugged in. The LEDs located on the back of the device will blink when charging. As the Juice Pack Pro 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 Pro, 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 Pro is fully charged, and one LED means that it is almost empty.

Protection Circuitry: The Mophie Juice Pack Pro features built-in short circuit, over-charge, and temperature protection.
