Here’s a cool phone accessory I ran across: Powermat USA
There are two classes of devices that can be used with this charger. Supported devices (iPhone, iPod, BlackBerry, etc) are provided with a replacement back cover which contains the wireless interface. All other devices have to use a small square interface with a mini-usb connector attached.
How does it work? There is a pad which is connected to a wall-wart charger which you plug into the wall. To charge your phone (with the replacement back cover installed), you don’t plug anything in, you just lay the phone on the pad. This is really nice because in addition to being futuristic and geeky, you shouldn’t have problems with the phone not charging overnight because you didn’t get the plug inserted “just right”. I’m quite sure I’m not the only one who has had their cell phone die part way through the next day because of this.
So, while I think this is a great product, and just might have to get one, I do have to wonder about the second category of devices. They give you a square box with a cable sticking out of it, and you put the box on the charging pad, and plug the cable into your phone.
Um… I just can’t see how this is any better than just plugging the original charger cord into the phone. In fact, I’d call it worse because now there’s another item in the “charging chain”, and any link in that chain which fails causes your device not to charge. As a result, I don’t think I’d have any use for the charging adapter, and would only want to use this with “supported” devices which have all the cleverness built into the replacement back cover for the phone.
