The Duracell Powermat for the iPhone 4 and 4S
The sleek design, available in white or black, is an upgrade from past Powermats, which seemed to be a little blockier and less “Apple-esque.” In addition to the new backup battery, there is a next generation “smart” feature that actually stops charging your device after it reaches full power as not to waste energy or ruin your battery life. Simply plug in the powermat, slip on the case and juicing up is as simple as putting your phone down. It's as easy as that, right?
Well, not really. First of all, the slip on case is a little bulkier than a standard iPhone bumber or case. It's not a huge difference, but if excess weight isn't your thing, it's a little inconvenient. The cases are available in a variety of colors, however, so if you don't mind the bulk, you can make the case your own. Secondly, the charge starts when the Powermat logo on the case aligns with one of two logos on the mat. It's a little easier said than done and takes a couple of tries to set it down properly and hear the bleep that lets you know you're charging. It's also easy to knock off so if you're charging by your computer, an errant elbow will knock it off.
The killer feature, in my opinion, is the portable backup battery. I can't remember the last time I was at a festival, traveling, at a game, on a road trip, or even just having a busy day, where my phone didn't die. The backup battery is small enough to carry in your back pocket and can give you almost a full charge to double your battery life. The wireless charging plus the backup battery make for a nice combination and worth the $100 price tag.
