iWALK
Chameleon
There’s nothing worse than being caught out
with a flat iPhone when you’re on the road and away from a powerpoint. That’s
where an external battery pack comes in handy.
Korean brand iWALK makes a range of
options. This one, the Chameleon, is a battery integrated into an iPhone 4/4S
case.
It has two main selling points. First, it’s
a 2000mAh model, which means you’ll get a full iPhone 4 charge out of it. You
can leave the pack turned off until you need it, or turn it on straight away
and use its power first, extending the life of your phone battery.
Second, it comes with a variety of
replaceable upper covers in five colours: White, Black, Pink, Lime and Yellow.
The lower half of the case is a rubber-touch black plastic.
When assembled the chameleon is within a
millimeter or two of similar units. Adding 6mm to the width, 1.2cm to the
length and 8mm to the depth of an iPhone 4S, it’s not exactly svelte, but it’s
not too bulky either. It weighs 78g.
Three blue LEDs on the base of the unit
make it easy to tell how much power you have left or what the charging status
is. A micro USB port can be used to connect to your Mac for charging and synching
with iTunes, so there’s no need to remove your iPhone.
Buying advice. The iWALK Chameleon does just what it’s supposed to – extend the
working time of your iPhone. Our only quibbles are that the covers are a bit
bright and the case itself could have a nicer design.
