3.0 out of 5 stars Nice design, perfect size - but capacity is disappointing., 26 Dec. 2013
Verified Purchase(What is this?)
This review is from: Kinps®2300mAh external power pack case and rechargeable back Up battery charger for iPhone 4 & 4S (Wireless Phone Accessory)
Update on Jan 2nd:
I revise my review to 3 overall stars with this update. We use all 3 purchased covers in the company and all 3 covers can only charge Iphone from 80-82%. Its just not good enough for a 'supposedly' 2300mAh battery, compared to my other covers that are 2000 and 2100mAh. We still love the size and weight of the cover but charging power lacks.

--------------------------------

I give it 4 stars when in reality, and solely because of charging power, it only deserves 2 because the expectation from a 2300mAh demand a lot more.

Good:
Design is nice, material feels very nice and this pack doesnt add size to the Iphone at all, like other battery-covers. Its just the right size, nothing more. Not adding size and the fact that it slides well in and out of a pocket is something I like. But not all is good.....

Its supposedly a 2300mAh battery but can only charge my Iphone (while not being used) to 82%. I have other battery-covers, the Trent at 2100mAH and the Mophie at 2000mAh.
The Trent can charge 100%, the Mophie can charge almost 120%. Also, when charged, you HAVE to use the Kinps quickly after, because the juice is zapped quickly from this battery if you let it sit charged and unused on a table. Charge it full, leave it unused for a week and there is not much juice left. I have tried and the result was just dismal.

I dont know if Kinps are lying and/or there is a great loss of power in their battery but in no way it should be such difference compared to the other less-capacity-battery-covers. It should be able to go to 150% but only delivers a lot less than expected.
Also the charge button should definitely be recessed since being on a table could accidentally turn it ON. The button is no issue at all in real life but should be mentioned for future design changes.

The Mophie delivers every time and even if I leave it unused for quite a while, it will still deliver a solid 80%. Mophie gives a solid protection to the phone also. Downside is that it makes the Iphone a bit bulky and hard to get out of a pocket due to its 'sticky' rubber surface..

The Trent cover is a slight favorite over the Kinps due to charging power. As the Kinps, Trent doesnt add size which I think is a big trait for a cover.

Would I still recommend the Kinps - yes indeed. For price, practicality and it DOES charge the phone enough to justify buying it.
