Powermat Powers Devices Now
Powermat has magnetic induction system that is similar to what eCoupled offers, which it first demonstrated last year at CES. But while Powermat representatives talk about how the firm’s devices will boil water and power flat-screen TVs in the future, the company seeks to launch consumer products without waiting for device manufactures to get on board first.
Powermat will offer five different styles of a thin charging mat by this fall: from a modular mat that can charge up to six devices to three-device mats to put by your bed and a folding model for travel, with prices between $129 and $159. If you want to charge a laptop as well as phones, iPods, headsets, cameras, GPS receivers, and other small devices, you’ll need the PC+ model. The PC+ model has a power disk that you plug into a laptop and place on the mat (which can charge two smaller devices at the same time).
One mat can charge several devices, but each device will need a $30 charging adaptor, which can be built into a protective case or a dock. While most devices will initially require a "power disc" that plugs in, you gain efficiency by not having multiple power-wasting adaptors plugged into the outlet. So far there are around 10 different adaptors.
Like eCoupled, Powermat can get data back from the device through the charging connection, so it knows what voltage to send and when to stop charging. It also promises to transfer data to devices in the future "at very efficient rates," so you could charge and sync your iPod at the same time.
You’ll be able to choose from a range of charging mats and Powermat will have adaptors for existing devices.
The puck-like power discs aren’t yet small or convenient, but they let you charge devices that won’t fit in a dock or a case.
The same Powermat works with charging cases, charging docks, and devices designed for Powermat, like a clock.
