Additional power for your iPhone is an absolute must. If you ever travel with your iPhone, even for just a day, you’ll know what we mean.

The Mophie Juice Pack Air in action

Checking your emails, playing some light games and playing films suck your iPhone’s battery quicker than you can say “Oh, where’s my charger?”. You might consider purchasing an external, top-up mobile charger for your iPhone or even a car charger. But the external battery is just another thing for you to carry or to lose. You’re not always with your car, and not everyone has one.

The Mophie is well protected in it’s packaging…

The instructions are pretty handy…

With that in mind, we review the Mophie Juice Pack Air.

The Juice Pack Air is a combined case / iPhone external battery. Mophie claim the device will virtually double your 3G or 3Gs’ talk, surf or rock time.

The Mophie has been officially certified by Apple, as a “Works with iPhone 3G(S)” product and provides both protection and extended life for your phone. Let’s take a closer look at the Juice Pack Air.

The Juice Pack consists of 2 ‘halves’ – a short top that envelops the leading edge of the iPhone – with cut-outs for the camera, power & silence buttons and the headphone jack.

The 2 halves of the Mophie

The bottom half has an iPhone dock, 2 moulded dimples that open up the speaker and mic that would other wise be covered. On the bottom edge, where the normal dock would be, is a mini-usb port for charging the Mophie and a small rocker switch to toggle charging modes.

Finally on the rear you’ll find 4 small blue LED lights that indicate the power level of the Mophie’s internal battery.

The whole case is finished in a high gloss finish and is available in either black (like our review sample), white, purple or a new soft-touch finish red.

As a case, the Mophie is impressive. It’s made of a very tough plastic and the case follows the iPhone contours and buttons closely – minimizing dirt and dust ingress.

Ergonomically, the case is very good. In the hand, it feels chunky but not uncomfortable. Mophie have done well to keep this case as thin as it is, thanks to the clever design and lightweight battery. Once fitted you really don’t notice the Mophie one bit – that is until you need to top up your iPhone.

Iphone profile vs the Mophie

Picture the scenario. Your in town, on the move on your way to a very important annual meeting. You simply must not lose contact with the office as all calls are been forwarded to your iPhone. But what’s this? You’re incredibly forgetful, and you haven’t charged your iPhone this morning. Fortunately, you have your Mophie Juice Pack fitted, and that is fully charged thanks to it’s stand-by mode that conserves the Mophie’s battery level.

So, you flick the switch – and your iPhone is heading out of the red – and should see you double the iPhone battery level.

The Mophie is a real life saver.

  • Internet Use: Up to 4.5 hours on 3G | Up to 5.4 hours on Wi-Fi
  • Audio Playback: Up to 20 hours
  • Video Playback: Up to 6 hours


Now it’s time to talk tech.

The Mophie has a built in LiPo battery rated at 1200mAh. LiPo’s are very light batteries and relatively small in form factor – meaning the Mophie adds little to the iPhone in weight or bulk. The battery has built in overcharge, short-circuit and temperature protection – which is always nice.

Charging the iPhone is super simple – simply connect your iPhone to your Mac and you can still charge (both the iPhone and the Mophie simultaneously) and sync the phone using the ‘pass-though’ usb – remember, there’s a dock connector built into the Mophie.

Using Intelligent Power Distribution, the Mophie always tells the iPhone to run off the Mophie power over it’s own battery – so when the Mophie runs out, you still have a fully charged iPhone.


The Mophie get’s a huge thumbs up from us, giving it the Apple Reviews seal of approval

To conclude, the Mophie Juice Pack Air is the product I want to take on my next trip – thanks to it’s unique case / battery concept. Other batteries we’ve tried only clog up your luggage – whereas the Mophie is right there on your phone all your time. It’s very comfortable too, adds little weight and size to the phone – and it looks good.

This is THE external battery you’ll want to buy for quick-out-and-about topping up of your iPhone’s battery.

You can purchase the Juice Pack Air directly from Mophie for $79.99.
