While just about everything else has cut the cord and gone wireless, the last remaining cable, the power cable, is trying to follow suit. Recently, a few companies have come out with wireless inductive charging accessories, however, the wireless part is a bit misleading. I think a better term to describe the technology would be “plugless” since you still need surface contact to provide power for charging.
A few weeks ago Dell announced a new business notebook computer the Latitude Z. One of the many new features offered with this high end business laptop is the capability to buy a separate stand that allows wireless charging. The stand and the notebook have inductive charging capability which allows the user to simply place the notebook on top of the stand and wallah, it’s charging. Truthfully, this is not significantly different than plugging in a power cable, none the less it’s pretty cool.
A couple of other companies are offering inductive charging accessories as well, with solutions for mobile devices. Powermat and Pure Energy Solutions offer products for Smartphones and the Nintendo DS. They are both similar in that the kit has a charging mat and a charging skin for the phone or DS. Once the skin is on the mobile device, just set it down on the charging mat. Both companies offer a charging mat that can accommodate 2 to 3 devices however you’ll need to buy a separate charging skin for each device. The Powermat kit which includes the mat, a universal adapter and one skin retails for around $140. Additional skins are $40. The Pure Energy version retails for around $80 and additional skins are $35. The Palm Pre also has an inductive charging kit available which is similar to these solutions.
So is plugless charging really that much easier than plugging in a power cable? Not really, but once the cost comes down, the convenience is probably worth it. Where this really makes sense is when it’s applied to multiple devices. Rather than have 3 or 4 gadgets each charging overnight with their own power cable, you could use one mat with one cable to charge several devices. I can imagine coming into the house and dropping my cell phone (or two), as well as my wife and kids phones onto a mat and them all charging from a single plug. That truly does eliminate cables and clutter.
