Re: Convenience
Good way to sneak a nap tho' - "Sorry boss, just charging my phone...Zzzzz."

Re: Convenience
I think if people start putting their heads on wireless charging mats the FCC will quickly issue SAR limits which will kill the technology!!  Let's hope that isn't the outcome.

Re: Convenience
Uh-oh - hadn't thought of that. You'd need to lay your head on the mat to use your phone. Just slightly impractical.

Re: Charging different devices at the same time?
Is automatic detection and hence charging possible. If so the charger can sleep till a device is placed on the mat thus reducing power wastage.

Convenience
SB I agree it is convenient to just place the device on the charging mat. However, with wired charging method, one could still use the device while it is charging. Can this be done with wireless charging?

Efficiency?
The EPA estimates there might be 2.4 billion power adapters in the US.  The efficiency of these, as well as their consumption when plugged in but not charging a device is a big concern on total energy footprint.  Any thoughts on the efficiency of these wireless charging systems vs. wired?

Re: Charging different devices at the same time?
@SunitaT,

I agree that there are some wireless power transmitters that use Adaptive resonance charging technique to charge multiple devices of different power formats (inductive coupling (MI), magnetic resonance (MR), and Qi technology into one solution, which means, whatever be format of the device adaptive Resonance technology will allow you to charge it with the same format).  I am excited to know if a single transmitter could charge multiple devices at the same time whose power requirement (or charge time) are different. Any idea??

I assume, the mats that you mentioned have multiple receivers points, with each device using a different charging format.

An interesting info about wireless charging on the wireless power consortium page.

Re: Charging different devices at the same time?
amrutah,

Presently innovation is going on Adaptive Resonance wireless charging where we can simultaneously charge multiple devices. These charging mats makes use of adaptive resonance techniques which are smart enough to know which device needs what kind of power.

Wireless Charging: All Set for Takeoff
Siamak, Thanks for the post.

As of today to charge a phone without a cord, most phone owners would have to buy a smartphone case or battery pack with an embedded receiver, and then use a charging mat with a compatible transmitter. But these adoption barriers could soon disappear with adoption of a universal wireless charging standard.

A universal standard will allow us to have charging mats in public places, where users can recharge without having to carry around a power pack.

Re: Take-off supported with Qi standard...
amrutah,

Yet to see any standard that would compete with the Qi. While Google and Samsung are trying to bring their own devices with varied specifications, the industry is yet to come in terms with something which could revolutionize many industries, especially, the automotive industry. If electric vehicles could be charged fast with standardized devices, it is going to be big time.
