5.0 out of 5 stars Excellent seller communication 4 Mar. 2014
Verified Purchase
The first case I purchased was faulty, but the seller contacted me immediately to send a replacement (which I got in 2-3 days). I was delighted about this, as I really love the case! It's extremely light and slim, doesn't make my phone appear bulky and charges it from 10% to about 60% or even 70%, which is more than decent for the convenient price.
Really loved the way the seller handled the situation, excellent customer service. Highly recommended!

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.

Was very surprised and impressed with this product as I expected it to be bulky and heavy at the same time but it is neither. And it works brilliantly

1.0 out of 5 stars Buyer beware - this caught fire. 29 Sept. 2013
Verified Purchase
Worked fine for the first few weeks I had it but then suddenly stopped working in the middle of recharging my iPhone 4s. No light, no warning. i assume it was out of charge so plugged it in and seconds later I smelled burning plastic and saw smoke coming out of it. A section of the pack had melted and fortunately I managed to pull the cable out at the mains, but not before burning my hand trying to move it.

The sellers were quick to refund me but strangely didn't offer a replacement - is this a common problem I wonder?

Please be careful with this and if you do buy one - don't leave it charging unattended.

5.0 out of 5 stars Great Product 27 Jan. 2014
Verified Purchase
Recommended for those who have a useless iPhone 4s with battery life less then a day. I use my phone constantly on the go. battery life has come to a point where it was either a new phone (which I didn't want to buy - Waiting the Sam S5), take my charger with me, or this product. sufficed to say, I went for the latter. I can get 2.5 full cycle charges from this devise which allows for approx 36 hours of usage without the need for me to charge at the mains. (these numbers are based on the current poor condition of my iPhone's battery, my usage and the fact I used the stop clock to time it). its well made, durable, love the blue light indicator for charge remaining. Haven't noticed distortion from the speaker. Haven't noticed any overheating, but I charge it separately when I know I will be needing it. It offers some phone protection to the rear, but not much to the front/top. you get used to the overall size and weight increase. sits comfortably when holding it. I haven't timed how long it takes to charge the unit, but its around a couple of hours. I just leave it charging overnight for the following day. I've had it for a couple of months now and I can not fault it. it extends the usage of my phone. it is why I bought it, and it does a great job too. get one if your phone's battery is on its way out!

No too heavy to carry as an extra and gives great star battery life to my 4s. Also like the fact that I can use my iPhone charger and don't need a separate one
