2.0 out of 5 stars Overheating and melting, 20 Feb. 2014
By 
Verified Purchase(What is this?)
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.

Looks to me like you are trying to charge the power pack while connected to the phone in which case the power pack cannot take the current going through it and overheats. The power pack must be charged separately which is why its cheaper that similar packs.
