Verified Purchase(What is this?)
This review is from: Portable Battery Charger Case External Power Bank Pack 2350mAh Back Up Rechargeable Extra Supply For IPhone 4 4G 4S BC001 (black) (Camera)
it fits the phone well,
has nice feel,
charges the phone when it is low or flat
isn't too bulky or overly heavy and doesn't change the balance of the phone too badly
One of the side lugs has broken off already (suggest it stays on to prevent this - carrying around in pocket or bag leaves it susceptible to breaking any of the lugs off.
It givens no indication of how much charge it has left therefore I find I am charging the battery nearly as much as the phone - the led should show charge available and you could make a decision based on that - have had it run out without charging the phone much at all.
It doesn't seem to 'fast' charge the phone as much as I thought it would - takes ages to get he battery back to 100% form say 40%and seems to drain this battery flat doing it.
The pass through is very strange - if you want to charge the phone battery quickly you need to remove this external battery - charging the phone from the battery and then charging the battery at the same time (which seems to be the only way to do this) when it is fitted to the phone takes a long time - if you want a fast charge on the phone take it off this external battery.
As an emergency restorer of power to a dying phone it works for me - as a means of extending the battery life of the phone or reducing the charging overhead it doesn't - it actually increases the charging overhead and makes it slightly worse but that is probably just my usage patterns.
