The induction charging company has not only slimmed down its Powermat system for the EVO, but for a range of other top selling smartphones as well. Some of these phones include the Apple iPhone, HTC HD2, Motorola Droid X and the BlackBerry Bold and Curve.

To give you an idea of just how much slimmer these new models are, you will see a video below after CJ Lippstreu from Smart Keitai purchased one. The cost of both the mat and receiver door set will cost $59.99. You can purchase just the receiver for $39.99.

Do you think that in this day and age we should rely on third-party batteries in order to have enough power to keep our cell phones running for a complete day?

When we say stocking them, the retail giant has them in stock and is about to allow their shoppers to purchase them – although we have no details of a date or price. We can expect them to sell at a competitive price, just like most other products from the store. Photo evidance of this can be found on Joseph L. Flatley’s post on Engadget.

Both the Apple iPhone and the HTC EVO 4G will benefit from the powermat, as they have never had the best battery performance – the fourth-generation iPhone battery is a vast improvement over its predecessors, but still has a long way to go to compete with its rivals.

There are those who are not convinced of the powermat, as you will need to put your EVO 4G or iPhone 4 in a case and then place it on the charging mat. This is not exactly as good as the Palm Touchstone – now that is a device that is worth of another mention.

Do you think that the powermat is a useless accessory?
