The technology to wirelessly charge gadgets surely comes in handy. It has been available in the United States, and has now come to Hong Kong. The new Powermat charger allows you to throw away all those power cords for your phone, PDA, Nintendo DS and iPhone, among many other things.

According to the company, the technology uses the principles of magnetic induction and some new technology to transmit power to batteries without an actual electrical cord.

The catch is that each device will have to be made Powermat-ready by adding a 'receiver' to it. That means extra money - and extra bulk on your device. So far, there are only receivers for the Blackberry, iPhone and Nintendo DS Lite.

But the company ships each Powermat with a universal receiver, called the Powercube. The receiver connects to a range of devices through an adaptor. If you are using an older gadget, or a niche brand, you might want to check if an adaptor is available before you buy the Powermat. There's an abundance of smart technology inside the Powermat, including a magnetic alignment system that makes sure the device is in the optimum position for charging. The system also knows when to stop once the device's battery is full. The Powermat is capable of charging up to three devices simultaneously. The Powermat costs HK$998, with charging receivers for the iPhone and the Blackberry at prices ranging from HK$298.

Pros: wireless charging, less cables, less mess, can charge three devices at a time

Cons: might not support all devices (particularly older models), adds additional bulk to devices in the form of a receiver
