Reviews for Mophie Juice Pack Air for iPhone 4S

Here's the deal. The product works great out-of-the-box. Due to the design, the micro USB connect gradually becomes loose sinking into the case and eventually you lose your ability to charge the unit. You will be lucky to get more than 6 months of use from this product. That said and considering the disposable nature of this product, I would recommend looking at less expensive charging cases that perform just as well.

I have had three (bought two, Mophie replaced one). Each one is more useless than the last one.
The problem is simple, the plug is not stable and once you plug it and unplug it several times, it becomes loose and will no longer take a charge.
I have complained directly to Mophie, am I will wait for a better design before I buy a new one.

I bought this and instantly fell in love. Not only did this case protect most of my phone; it felt great and wasn't terrible so far as looks go either. It was great with the battery life as well and it definitely is not overrated. I had no problems with until about 3 weeks in when suddenly it wouldn't charge. I tried different chargers and different outlets and nothing would bring my Mophie back to life. All in all I'm sure I got the defective one but Mophie and Apple wouldn't give me a new one. The one bad thing about all the Juice Pack Airs' is that they don't allow you to sync and charge at the same time. The only one that lets you do that is the Juice Pack Pro which is about $20 more. I just picked one up so hopefully it works out this time.

loved my juice pack for my old 3GS, never ever had a prob with it. Bought this new juice pack for my new 4GS same night I bought my new phone, I was so thrilled. Now two months later, it won't take a charge from the micro USB cord. No replacement bases on the Apple website or on Amazon or on Mophie's website either, So it's now a piece of $80 junk. what a f'ing scam. If it had broke in the 1st 30 days I could have gotten a replacement no questions asked, but oh no, it broke after 60 days. I know it's not an Apple product so not Apples fault or covered by AppleCare, but at $80 you'd think it would last longer than 60 days. what a rip

Just like other users I have the same problem with the micro usb port breaking off inside the juice pack. I'm on my third one.

I bought Juice Pack Air from the apple site. I guess the one sold through Apple site has 2 piece design. There is a lower part that houses the Micro USB connect, the switch, and the 30 pin connector. And the upper part that acts as a shield as well as probably houses the battery.

In first month of usage, the paint was peeling off. You can imagine on a white case how horrible it could look. In 4-5 months time, the lower part that has the USB connector was wiggling a lot and had to be quite deftly held together for the charging cable to actually make the connection to charge. The following month the plastic began to wear off ... i mean it was chipping off, broke.

Writing to Mophie yielded no result as they claimed that they have one year warranty from the date of purchase. Unfortunately in my case, i did not raise a customer complaint right in the beginning and did it quite late in the game. So there i guess they are right.

My final conclusion on this case is:

a) It looks good for first few weeks till the paint starts to wear off and it gets uglier and uglier by the day.
b) The Lower connector is very poorly built. First the Micro USB port will give way. Next the Plastics will begin to wear off. The toggle switch also looks very vulnerable.
c) No way you will get 500 charge cycles as claimed. In my case it completely stopped working in 1 year 2 months. It does not add up to 500 charge cycles.
d) The capability to charge the phone also depletes very rapidly. First 3-4 months, while you are getting used to poor quality of the paint job, it does charge the phone quite well but then quite precipitously the ability to charge drops.

i dont know whether they sell the lower piece seperately or not? If they do, i would want to know because may be just may be i can extract few more months of life out of this thing. And if they dont, then this is nothing but a very expensive paper weight.

Mophie may love you ... but my love for Mophie went out the door!

I bought it thinking that it would keep me from having to charge for 2 days. It barely lasts an additiona 6 hours and I keep all of my apps closed and blue tooth turned off. Also a horrible feature of this "lack of Juice" pack is the power plug. it is so short that it keeps falling out and you don't even realize it. That is ok when you are in the office and it is lying nicely on the desk, but when you are in the car charging it, it is constantly falling out and not charging.

Stopped working about 4 months after I purchased it: doesn't charge anymore. If I find the receipt, I will send it back and look for another brand. The idea is good but it's a lot of money for a few uses over 4 months

I purchased the Mophie due to the fact I travel 4-5 days a week and need a portable power source for the iPhone4. My first trip with the Mophie was this week and it was fully charged on Sunday. Very excited because I thought this could be very good product/fit. Monday, the charge didn't hold any more than 20 minutes while on my drive from the airport to the office. I thought it was my fault so I charged it on Tuesday for most of the day. I had four lights on the battery. Again, the charge was no longer than 20 minutes. I called Apple Support they are shipping me a new one. Previously, I have purchased Portable mobile chargers from Amazon & Target for $50-60 less than this product. These have worked well other than the bulkiness of the extra pack on the phone but charges will get at least 90% from 20% in a short time. I’m unsure if I got a defective one or not. I will change the rating if the replacement works as advertised

This is the 2nd one I've had. Now this one is having the same problem as the first. The charging connector has failed on two occasions and I'm not gonna try a thrid. The product is great when it works but it doesn't work for very long.
