The Portable Mat -
As you saw in the image above [in the Package Section] the Portable Mat is articulated to allow it to fold down into a much smaller space. This then fits inside the carrying case [of course], each of the three sections provides an area for charging a single device.
The sections contain the magnetic part of the Magnetic Induction charging system. But there is more to the system than that [as we will cover below]. As you place any receiver [this is what Powermat calls the cases and cubes] onto the pad you will hear an audible sound to indicate that a good connection has been established. At the same time a small light on the front of the section your device is on will light up.
Along the back edge of the device is a single USB port and two small round buttons [right next to the power port]. The USB port allows you to charge an additional device while the buttons control the visual and audible indicators. The light can be turned off while the audible sound can be cycled through two volume levels in addition to be muted.The Power Cube -
The included Power Cube is a multi-purpose device that comes with the Powermat charging mats. This allows you to use the Powermat right out of the box without the need to buy an additional receiver. It comes complete with eight charging tips and a case that can hold roughly three of them.
The tips cover the most common devices in the portable device world making the Power Cube great for keeping your Bluetooth headsets charged.
How does it work -
As we mentioned briefly above the Powermat Portable Mat relies on Magnetic Induction [Also called Magnetic Field
B] to provide power to your devices without the need to wires. However, this is an over simplification of how it works
. Powermat does indeed use Magnetic Induction to create a static magnetic field used as a conductor for charging. However they have also included a “handshake” process to make this more efficient than normal. Each receiver is able to identify the product it is connected to and convey this information to the charging mat. This simple information allows the mat to provide the proper power to the product with as little waste as possible. The RFID portion of the handshake also allows the charging mat to know when the device is full charged and to cut off power to the mat at that time.
This means that you could have multiple devices resting on the mat and not draw a single watt from the wall. The mat is also able to tell [through the same RFID] when the device goes below a full charge. It is able to turn the power back on to the device for the short amount of time needed to bring it back to a full charge.
Now this is not a complete explanation of how the technology works [nor is it meant to be one] but is intended to show how Powermat has used an old idea and made it into a viable solution that can be used today.
