2.0 out of 5 stars Overheating and melting 20 Feb 2014
By DaveE
Colour Name:Black| Size Name:1900mah|Verified Purchase
Portable 1900mAh External Power Pack Backup Battery Charger Case for i-Phone; I have purchased two of these to date and consequently feel well equipped to review this product.

I purchased the first in Aug 2013 from Oceanmap via Amazon for £7.64 including carriage. I wanted extended battery life so I could GPS continually while on 4 hour plus cycling rides.

The case worked well at first although occasionally the phone displayed the message 'Charging is not supported with this accessory' but if switched off and on again it would continue to work. One day while charging I noticed that the case had overheated at a location close to the charging socket.

It got so hot that the case softened and deformed leaving a concave hollow at a point on the case where it was hottest. Despite this concerning development the case continued to function, unfortunately I later dropped the phone a couple of times and the case split.

I then decided to risk buying a replacement hoping that the overheating was not an inherent fault and in Jan 2014 I purchased an identical case for £6.34 including carriage from ‘G For U—Ship from HK’ via Amazon.

Once more the case worked well at first but again occasionally the message 'Charging is not supported with this accessory' would appear. Then recently the case overheated and got very hot, softened and deformed again leaving a concave hollow in exactly the same place as had happened on the first case, nevertheless it continues to work.

I cannot recommend this device as the overheating fault is a serious concern.

3.0 out of 5 stars Pros vs. Cons 9 Oct 2013
By Ben
Colour Name:Black|Size Name:1900mah
I have only had this case for a couple of days. I will update the review if any of my views change over time.

POSITIVE
Build Quality - everything feels well put together and the finish is a nice mat black
It Works - so far it does what it says on the tin
Easy to insert and Remove the Phone

NEGATIVE
Weight and Size - it isn't light so it does add a noticeable amount of weight to the phone. It also adds about 60% to the depth of the phone.
No Syncing - it doesn't want to be recognised by my computer, or my in-car headunit. So I have to take it from the case every time I want to use the phone with either.

I am undecided as to whether the pro's do outweigh the cons at this moment. Time will tell...

1.0 out of 5 stars Beware! 16 Jan 2014
Colour Name:Black| Size Name:1900mah|Verified Purchase
I purchased several of these Backup Chargers for my iphone 4s......although the others were puchased from different suppliers.

I left the Backup Charger in my computer at work for approx 5/6 minutes at the max....when I got back into the office smoke was coming from the case.....the case was literally melting!
