This is The Most Powerful Battery Case for The Samsung Galaxy S3 (There’s an iPhone Version Too)

One doesn’t see too many battery cases for the Galaxy S3. Unlike the glass-fortress iPhone — for which battery-cases are more numerous than species of bird — the S3’s battery is easily removable, somewhat lessening the usefulness of an external battery. But that didn’t stop iWalk from coming out with the Chameleon Easy, an impossibly sleek monster of a battery case with 2800 mAh on tap — which iWalk says is the highest capacity of any S3 battery to date.

There’s an iPhone 4/S (no love for the 5?) version too, simply called the Chameleon, but with the seriously-reduced capacity of just 2000 mAh. Still, that’s way more than enough to fully charge the iPhone 4/S battery, both of which are around 1400 mAh. On the other hand, the iPhone’s Chameleon comes with a power-meter and a handful of Skittle-colored, interchangeable faceplates.

The S3’s Chameleon Easy sells for $65, and the iPhone’s Chameleon for $60.
