Mophie juice pack air for iPhone 3G/3GS

Mophie’s juice pack air(available for $79.99 @ is the newest solution to the Mophie lineup. It is the slimmest 1200mAh rechargeable battery case on the market and comes in a variety of colors, Red being the newest with a soft touch finish. I have been using this case for a few weeks now and have some good and bad things to say about it.

First, lets see what you all get. Inside the box you get:

– juice pack air

– Micro USB to USB cable

– Instruction manual

Thats it! I was disappointed to find out that they didn’t include any screen shield and felt that after paying $80 for a case, it would have at least included one.

But for not having included a screen shield with the case, they have included a lot of great features into the product. They have a battery status indicator on the back that allows you to see the remaining charge that is in your battery pack and is easily accessed by the push of a button. They have also included a few new features with the juice pack air. An on/off switch that allows you to choose when you want to charge your phone. I thought this was a great feature as I could charge my phone when I wanted to and could reserve the battery for later if desired. Another new feature on this case is the two piece design.While using this as an everyday solution is great in theory, I found the bulkiness of this case to get in the way of everyday use. Keep in mind, while this is the slimmest case on the market that includes a battery pack, it still is quite large. I found it uncomfortable to wear in my pants pocket and while wearing it in a fleece jacket pocket, it pulled to one side. I would have also liked to see a bit bigger of a cutout for the volume and vibrate switch as I had to use my nail to flick it from vibrate to on. One last thing about the design is that it has no lay on the table design. There are no raised edges and the chrome bezel is completely exposed to scratches.

Charging the Juice Pack Air is very simple. I’m not sure why they decided to use a Micro USB as oppose to a Mini USB, a standard that has been used for most small devices for quite some time. Charging it for the first time I found to be a lengthy process. I contacted Mophie regarding this and they informed me that when the iPhone is connected, it maintains a 70/30 charge ratio; 70% being the iPhone and 30% the Juice Pack Air. This for me meant that I would usually end up charging the pack before I went to bed. If you have no problem taking the case out to charge it by itself every time, it does charge faster, but defeats the purpose. The status indicator on the back blinks as it charges and will display a solid 4 bars when it is full. Being a 1200 mAh battery, on one full charge of the case I was able to recharge the iPhone from dead back to 100%. This allowed me to use the phone almost an entire day without needing to worry about charging it up. A feature I really like that they included is their ‘Pass-through USB’ design. This means that you to to sync to iTunes of your Mac or PC without having to take off the case.

I’ve had a few questions regarding the signal/call quality with the pack. Others have reported that they have lost a bar or two or had dropped calls. I found that in areas where I had a strong signal, I had no difference in signal strength as well as no dropped calls. The weak signal areas however showed me problems, it would show ‘No Service’ or ‘Searching’ with the Juice Pack Air on where I normally would have one bar. Call quality was acceptable as long as I had a signal and callers on the other end said they had no problem hearing me. I never had the dropped call issue.

While this case does have its good and bad points, the good definitely outweigh the bad. This is a solid ‘all-in-one’ solution for traveling and Mophie has included a lot of great features with this case that make it a highly recommended purchase.
