Powerskin battery shell test for iPhone 4 and 4S

Even if the last
version of iOS has apparently improved autonomy as
You indicated it in our survey seen here, the fact remains that the iPhone is
Often in demand: telephone, web consultations, emails, learned,
push, etc ... So sometimes you have to give it a boost at the end of the day
Or on the go! This is why accessories manufacturers
offerCocks incorporating a battery.

We were able to test several already, for our already79th accessory test
iPhone, it's the
PowerSkinwhich went into our febrile hands.

Here is in pictures, our opinion on this shell for iPhone and iPhone
4s:

Premier contact

The shell is delivered with a mini USB cable and a notice in
French.

As soon as the packaging is released, it surprises doubly.

First of all by the fact that it isa single room, il
does not seem to be a piece that stands out to allow to slip
The iPhone inside. The shells that we had tested until then had
Always at least two parts.

The second surprise concerns thematerial used. Indeed,
While most battery shells are rigid, it is actually
In a silicone and therefore expandable material. It is pleasant to the touch
With an external appearance a little "peach skin".

It is this second feature, in this case its flexible side, which
In fact explains the first. Not being rigid, theiPhone is actually going
slip insideeasily.

Otherwise, we notice a discreet logo, that of the brand, it's a…
Poulpe! Why not ! Don't worry he is barely seen and
He's pretty cute.

For the rest, aprise synchrowill allow the connection of
the battery integrated on the back in the iPhone while abutton and
LEDs are discreetly integrated into the lower part, Thus
that aport mini USBwhich is on the side.

A very homogeneous, rather aesthetically successful set:

It weighs 82 g and has dimensions of 12.6 x 6.35 x 1.96 cm thick. This
is not the most compact that we have seen, for example,
Phonesuit seen therehad comparable height and width dimensions but
a thickness of 1.7 cm.

Finally, it displays a weight of about 82 g.

Recharge and capacity

The battery has a storage capacity of 2000 mAh which recharges
(Tested with the iPhone USB transformer) in 5 hours. This is relatively
Long, you will have to take your precautions!

The load level can be noted during recharging via the LEDs
located on the lower part, and can also be verified when it is not
Not connected, via short support on the button.

To use it, just slide the iPhone inside and then press
For 2 seconds on the button, the recharge starts then.

A largely sufficient space is arranged for the device cell

Regarding recharging, in about 2 hours, you will go from 2 % to 95 % and
Afterwards, the battery is emptied. It therefore allows an almost complete recharge. We
can still be surprised not to have any surplus at the end of the load of
the iPhone, because it has a battery of about 1500 mAh and the battery announces 2000
Mah, in theory, she should have been able to load more than a iPhone
complete.

This nevertheless almost doubles the autonomy of the iPhone, a
Real air puff at the end of the day!

Conclusion

Of a successful external appearance and pleasant to the touch, this battery allows
To double the autonomy of the iPhone, one can only appreciate. But as
Each time, it is at the cost of an iPhone that takes on the appearance and a weight of
Pdade the late 90s! So our advice is simply
to take this full battery to your bag or travel bag and
Put it only when the battery drops dangerously. At that time, we
gives a boost to the iPhone. And unlike the batteries that
branch under the iPhone (less expensive), you can completely use
your iPhone, store it in a pocket or telephone without this being a
Problem, it is just thicker. On the performance side, we saw better in terms of
capacity especially taking into account the 2000 mAh announced, a little disappointing on this
point, without it being a big problem.

She is
sold around 55 euros here for example.
