    FANTASTIC!!

    • Written by from Carteret

    This has been a life saver, literally... lets be honest, with heavy use the battery wont last more than half a day at best with the back light dimmed as much as possible. With the mophie case, you can get a charge from 10% back to 70-80%... Highly recommended!!!!

    Nearly Perfect

    • Written by from Chicago

    I've been a mophie juice pack user since the iPhone 3G and the product has only gotten better.

    The Juice Pack Air is intended to charge a dead battery up to approximately 70% full and it delivers again and again. If you're looking for a full charge, check out the Juice Pack Plus as it's marginally thicker and delivers a complete full charge.

    The Juice Pack Air is stylish with the two-tone colors (though I wish it came entirely in black) and functional at the same time. My only complaints are that the volume and sleep buttons were pass through like the Juice Pack Plus and that the LED lights would shut off after fully charged. If you have larger fingers the buttons can be hard to push with the opening on the Juice Pack Air and the LED lights can be very bright when they are all illuminated in a dark room.

    Very comvenient for docking in the car

    • Written by from McKinney

    I was drawn to this product because it has a bottom cap to get access to the dock with the phone still in the case. With Mophie's other offerings, you have to remove a top cap and then remove the phone from the case to dock it. The phone "snaps" into the case, so even with the bottom cap removed, the phone is secure.

    I only have two very minor complaints. Firstly, the status LEDs are rather bright, especially when I charge it on my night stand. I would also prefer that the center of gravity of the case be lower to make the phone easier to type on when in the case. I find that my hands and wrists are straining more to keep the phone upright than with my iPhone 3GS in its Juice Pack Air.

    third times a charm

    • Written by from Voorhees

    I am currently on my third replacement mophie now. Why you ask? The charge port for all these iphone 4 mophie chargers breaks if you try to move the phone while it's charging. The connector is just way too flimsy. If they fix that then the charger would be perfect. I am in no way rough with my phone but the design of the charge port is horrendous. As long as you don't move your phone while it is charging you will be fine. To be honest I still use it (the third one) but I cannot disturb its meditative charging process or it will banish me to the land of no charge.

    Poor design, short life expectancy

    • Written by from Lockport

    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.

    Great battery life, terrible design that will break.

    • Written by from Vancouver

    While this device is great for having extra battery juice, what the other reviewers say is absolutely true. This product breaks EASILY. Myself and two others have within a week of buying one, also damaged it -- One of us have already broken the charging port (as indicated by others to be fragile) and two of us have dropped the case and have cracks in it now. Thus, if you think your case will survive a fall, rest assured. It WILL NOT. Lastly, this device is uncomfortable to hold while plugged in because of the location of the power port. Mophie needs to go back to the drawing board.

    Awarding 1 star for the battery life, but really can't give any more due to the obviously faulty design: not drop resistant, power port is fragile, and the issue with holding the device while plugged in...

    Posting this review for black, white, and red products as they are all the same.

    One FLAW!

    • Written by from Redondo Beach

    My iPhone 4S is always in use during the day when I'm not home. The Mophie is a must have accessory for the iPhone 4/4S. I'm not sure if it really gives you twice the battery life (iPhone 4/4S battery + Mophie Juice Pack) I can't accurately determine that. But I know that when I go to work in the morning both are 100% and when I get home I've used 120% of the battery combined. The case itself fits pretty well in my hands which is a good thing for me because I have big hands and trying to text without Mophie on is like Elephant trying to neatly peel a banana. Even if you have medium to small hands it will still feel pretty comfortable in your hands regardless.

    But there is ONE FLAW and it took a month for it to reveal itself. The mini usb connection, I'm not sure whether its the male or female connection but now when I connect the cable to the Mophie to charge both my iPhone 4S and the Mophie it will not charge unless I press the mini usb connection a certain way. Before I was able to just plug it and it will charge. Theres nothing wrong with the iPhone therefore its the Mophie's mini usb port or the charge cable itself.

    Horrible

    • Written by from TOPEKA

    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.

    Great idea, terrible execution

    • Written by from North Vancouver

    Mophie has to go back to the drawing board with their design. The charger connection is useless after a couple of weeks. I've gone through two of the cases already & won't be buying a third.

    there are 2 juice pack airs

    • Written by from Forest Hill

    The apple store version of the juicepack air is newer, and is more compatible with other devices. The top is wide open, the bottom comes off to expose the iPod port. If you buy the juicepack air anywhere else it has the same "almost doubles your battery life" capability, but the other model is a little bulkier, less friendly to large headphones, doesn't easily let you access the ipod port, but seems to be tougher and protects the phone a little more.

    I prefer USB micro over the iPhone/iPod port anyway, so I never remove the case. iTunes syncs just fine, and the charger is interchangeable with my son's android phone. Supposedly the wireless performance is affected by the case, I haven't seen any difference.

    Not worth the case sticking, Impossible to remove

    • Written by from Caldwell

    I've always loved Mophie products, but this one has a huge design flaw when it comes to the 4S. Don't get me wrong it holds the charge and is fabulous for when you need that extra battery life. The problem is that you can't get it off your phone when you are done. I don't want that bulky case on my phone 24/7, just when I need it and you can't get it off. I literally had to pry my phone out praying I wouldn't break anything using two dulled knives to try and break the seal. It is ridiculous.

    Don't drop it!

    • Written by from Hilo

    I was totally impressed by the extended battery life in something so elegant. In the first week I dropped it! I have the white model so it may be more prone to sliding out of one's hand or off the car seat but it protected my 4s perfectly. Only one problem - now it won't charge. Other's have noted that if you push the micro usb in a certain way it might work. Apparently not if it lands on that corner.

    Mophie would not honor a warranty claim as it "is not a manufacturing defect". Well, don't by the juice pack if you are hoping that, while it may protect your phone, it is not durable enough to protect itself.

    I would never buy a mophie product again

    • Written by from Old Tappan

    I have 3 iPhone 4S I bought my family juice packs for Xmas n they all broke 6 months later. For $120 a piece it's not worth buying. They come apart very easily. I called mophie and they will not stand by their product even after explaining that every 6 months they brake. They don't care nor will they do anything after it being replaced.... You were warned

    Great accessory

    • Written by from Greenville

    I was hesitant to spend so much money on a spare battery, but I bit the bullet and did it. It was a very good idea. Not only does it double the iPhone 4S's power supply, it is a virtual suit of armor protecting your phone. Just the flip of a switch allows you to charge both the iPhone and Juice Pack at the same time. I would recommend this item for anyone interested in a compact way to boost power and protect the phone. I would also recommend the static plastic screen covers for full phone protection (Apple sells them too).

    The only problem I have with this item is that it overrides your home screen with a garish green progress bar, but I'm more interested in performance than appearance.

    I give the Juice Pack a good solid "A".

    Works well, BUT...

    • Written by from LAKEWOOD

    I love the feel of the case and don't mind the extra bulk or weight--I've gotten used to it. BUT. The USB charger is a piece of garbage. Don't even think about moving your phone while you're charging up, because if you drop it while the USB charger is plugged into the case, or move it the wrong way, the prong will bend and it may or may not be useable after that. I'm not talking about dropping it on concrete, just carpet or a couch cushion. I have had both situations happen. I returned the first case, as the wiring was completely sheared off inside the prong. The second one is now bent but still charges. I hesitate to buy another USB micro charger from this company.

    All this being said, the case does an excellent job of protecting the phone. That's just not why I bought this product, and if I can't re-charge it then $80 for a phone case is just too expensive.

    Good but...

    • Written by from Miami

    even though it charges my iPhone up to 80% it is extremelly difficult to take the phone out of the "case"- specially if you're a woman and want to keep your nails pretty :)
    The previous model (3Gs) worked better in that way.

    With the 4S battery, it's a life saver

    • Written by from Apison

    I can make it through a normal day and end up at about 10% battery on my iPhone 4S. But when traveling, for business or pleasure, my phone, data and app consumption goes up meaning the battery life goes down. The Juice Pack keeps me from having to ration battery power when my usage is abnormally high. The 4S uses more battery...the Mophie solves that problem quite effectively while adding a tolerable amount of bulk and weight.

    Tested for weeks with portable solar panel

    • Written by from Irvine

    Purchased for the normal reason, more battery time for video, netflix, hulu, etc or if i forgot to charge it. When i first took it out of the package i was concerned it would break apart to easily. After many months of use it has never been an issue. Then it got dropped and i again was surprised it stayed together. The unit charges great and uses the common usb charge syn cable (small usb). Took it on a 2 week remote camping trip and charged it with a small portable sunlinq solar panel. The battery allows for the higher power required to charge the iphone. So my findings are. 1) it looks a little flimsy but will do its job unless your careless. 2) The ability to use the usb connections is great, dont have to find an oversized apple adapter cable. 3) If you need a way to charge your phone with solar power its perfect and light weight for the backpack. The ability to turn on and off the charging with the toggle makes it the best choice i have found.

    So far.. so good. I'm lovin' it.

    • Written by from Hyde Park

    My friend had this Mophie Juice Pack for his iPhone 4 and he swears by it. Soo.. when I upgraded to the 4s a few days ago.. I decided to get this case. I realize I've only had it for a few days.. but I'm very impressed with it.

    First and foremost.. it's a really solid case. It fits my iPhone 4s like a glove. It adds a little weight to the phone.. and I kinda like that. It makes the phone feel more "solid". It also makes it more comfortable to hold.. and the "rubber like" back makes it less slippery to hold.

    The cut out at the top makes the ports accessible for earbuds etc. And the batter life seems to be pretty good. It's definitely a major improvement on the internal battery life.

    I usually start my day around 8:00AM.. and I consider myself a fairly heavy iPhone user. Constantly checking email.. Facebook.. browsing the web.. texting.. and talking on the phone. I work outdoors and on most days I listen to music as well. I also browse videos on YouTube occasionally. So far.. I've managed to get thru my entire day without even coming close to a dead phone. By 8:00PM... the Mophie battery is drained.. but I still have around 70-75% battery life left on the iPhone's internal battery. This is far better then it is without the Mophie.. when my battery would be at 35-40% by 3:00-4:00PM.

    I realize it's an expensive "case"... but it's more then a case. It's a battery and a case. To me.. the Mophie has definitely been worth the money~
