This Battery Cover by EasyAcc I could test for several days.
It is particularly suitable for traveling or for outdoor activities no longer to be 5 (5s) bound to the normal battery life of the iPhone.
There must a be clear that you have to take some swabs in purchase such a product.
Of course, the iPhone is heavier in total. Just 86 grams of extra weight, I think so but for just nor reasonable.
And the appearance of the iPhone is suffering a bit, because it of course looks a bit chubby through the shell.
Likewise, no longer fit some audio plugs because the audio-out has fallen very petite. For but a handy little extension cable is included so that "Jack" can connect as of ClickTronic also easily fat. But is a bit ugly, the solution.
These disadvantages are however more than offset by the significantly longer battery life when it was the main goal of purchase.
It comes with the case, two Cover (Black and Pink), a microUSB cable, a manual are (unfortunately only in English) and the already mentioned 3.5 audio adapter.
The installation is very simple
Once you have the iPhone-fitted the desired frame is simply not up clicks and you're done.
The back of the case is made of a silky matt plastic, which hardly takes fingerprints and can look very sophisticated.
I have noticed no chemical odors, which I always find important in those articles.
The shell is loaded by the supplied USB cable, either at one (not supplied) USB charger or on a PC. Charging for the shell in a 1A output takes about 3 hours.
The iPhone itself is loaded when you push the slider back to green. The potential danger this button to press accidentally, for example in your pocket is as good as ruled by the slider. Very good!
But Unkar me is if I ever have to take out of the sheath, the iPhone for charging. This is not described properly. But I'm assuming that you can load both the shell and the iPhone via the microUSB port that is yes geswitcht within the envelope on the Lightning port. Here EasyAcc should sometimes give an indication in the FAQ.
On the back is a neat recessed push button to display the current battery level.
With a fully charged battery the shell of 2,500mAh an empty iPhone can be fully charged 5 and it's even about a third residual current available. So thus doubling the life of the iPhone more than clear. Prima!
All in all, I recommend this product to almost 100%. This is especially true if the primary target is actually double the runtime. Only the lack of clarity during charging spoil the overall impression. This however only marginally.
That's why I like to give the 5 stars.
