2300mAh Rechargeable External Backup Battery Case for iPhone 4S (5V)

Pros: -Its fits perfectly in my 4s, and works without any problem. -The cable which recharges it is the same that is used by your iPhone, so you don't need to carry two different cables. -It has an USB output that can be used to recharge another iPhone or another USB device. -It has an power switch, so you can just use when you need it. -As its a case, it also protects your iPhone's back from scratches. -The stand is very useful when watching videos. -LED shows you the current battery status.

Cons: -The stand looks easy to be broken with constant use. -This case makes your iPhone considerably bigger and heavier.

Other: Buy it as you never know when you will need some extra battery.

Pros: - Realy good price! - Feels exclusive with the soft surface. - iPhone rests on a soft backing behind it. - Can charge other devices through the USB-output. - Smart design that protect your phone, and you don't have that dumb external device with cables and stuff.

Cons: - Get's hot when charging with the iPhone inside. - You never know how much battery its left.

Other: I don't think this is a 2300mAh battery, but it can charge your iPhone from about 5% to 100% if you don't use the phone. Also it gives you a backup-capacity ecual to the iPhone battery. Good quality. A must-have item!

Pros: Works perfectly with my iPhone 4, charging the battery fully from 0. Other devices can be charged by USB port, with the appropriate cable (not provided). The holding leg supports the iPhone in order to watch videos. We recommend charging the battery separately from the iPhone (the first two nights I charged both at the same time and it worked, but since then, when I try, the charger constantly puts charging iPhone and then stops, again and again, so it doesn't charge and makes noise every time it connects). Operation is simple: it works like a battery and a case: when the iPhone's battery runs out, move the button on/off and the iPhone battery starts charging as if you had plugged into the wall with a normal charger. The cover is not heavy, but when together with the phone, both weigh a lot, but it is also because the iPhone is heavy. It is made of hard plastic, and while it looks nice, does not adhere to the surfaces if you are expecting that (like the iPhone, don't adhere).

Cons: You can not tell how much battery is left in the case-battery. Just an LED that lights up when charging the iPhone in the On position. When taking pictures with flash, the pictures goes wrong, because the light reflects in the thickness of the cover. The cover does not protect the front of the iPhone, but as back part weights more, it is expected that if you drop it, the iPhone falls with the front facing up.

Other: Very useful for travel or if you use the iPhone a lot in a day, so it lasts until bedtime.

Pros: Looks good as a cover for the iphone it's just as big as the Morphie brand of backup batteries. The major plus for this batter charger is that is takes the normal iphone charger, not a micro usb or anything else. (mirco usb charges can be damaged more easily). The sound come out of the bottom a bit better due to the dirrectional hole at the base of it. You can also charge another usb device form it as well which i think is pretty cool, but no cable supplied. The extra weight is not that more noticable but i've got big hands that suits me better having a thicker phone.

Cons: Thier are a couple of things 1. The charge light is only a indicator, it doesn't go off or change colour if or when the phone completely chargers. 2. Like the Morphie charger if you plug your phone in while it is in the charger and the charger not turned on it will stil charge your phone. This charger does not do that so you have to have the charger on charging your iphone and also the charger at the same time this makes the phone get pretty hot. 3. The little back flip out stand is a bit flimsy but that's ok i don't intend on using it. 4. The phones glass face sits flush with the charger so thier is no lip so no added protection to the screen if you face it glass down (Not ideal).

Other: So compared to the morphie iphone charger which you can for a little bit ,i think i would perfer this charger mainly becase of the ability to use the same connector cable as the iphone cable. I don't like the micro USB cable as they are to flimsy.

Pros: It is a great product, you charge it at home. And when your on your way you got a way longer batterylife or you can use it to charge your phone. It has a switch to switch the battery on or off so you do not have to take youre phone out of the case.

Cons: The phone slides a bit to tight in the case but is does fit! (4S) I use it when i am running to extend the battery life so my Runtastic app keeps working till the and of my run (21km). Especcially when it is cold outside i need this extra battery. Con is that with the extra case it does not fit very well in to my sport armband, so i ordered a new sportband with DX which i hope is a bit bigger so my phone along with the case does easily fit...

Other: Good product. Does what it needs to do. The case makes the phone bigger so if you whant to fit it in some place it might not work.

Pros: Very easy to use and fits perfectly in a Iphone 4S. Red LED when charging the battery. LED green when the battery charges your iPhone. Fits in your pocket, even if bigger than the classic iPhone.

Cons: A little heavy but it is very tolerable. Your iPhone is twice as big.

Other: I am happy with this purchase and hope that the contribution of the extra battery will be quite satisfactory. In any case, the first look is flattering and I hope to be completely satisfied with this battery.
