Much Ado About Nothing?

This sounds like "much ado about nothing". If I'm near enough to the charging pad to charge my phone, I might as well plug in my USB cord and recharge at the end of my meter long leash (power cord).  It gives me more flexibiloity than trying to talk on the phone or surf the web while the phone rests on the charging plate. As a frequent traveler, I see the cluster of people on their phones at the power outlets, I don't see a benefit of having to get even closer to use the recharging plate.

I certainly understand some people would feel that way, DrQuine. But then, when I'd have to compete for precious power outlets at the airport (and there aren't a lot of them around), I do long for wireless charging pad.

Travelling with your charging pad

I don't think people will travel with their charging pad, but they will still travel with their charger, so unless the airport provides the infrastructure (as in pads), I don't see your argument. I see charging pads as mainly a home or work convenience. The difference in cost between an outlet with an extension cord and a pad (that still needs an outlet) is huge. Coupled with the limited number of devices a single pad can support, I'm not sure many places will spend that capital. Except Starbucks ...

How about in your car? Get in your car, put the phone in its cradle (with inductive charger), and drive. You can ask your phone for the nearest steakhouse, and listen to an mp3 fille, sent to your car stereo over Bluetooth.

Having to plug and unplug in the micro-USB charger every time you get in/out of the car gets very annoying after a while so most people wouldn't bother most of the time.

wireless charging to be defacto feature in laptops & cars

One of the biggest challenges in smartphones is battery life. When you are sitting in your car or at your desk, you want a convenient way to charge the phone.  

The technology is early and will only get better (and smarter).

Ubiquitous wireless charging, or at least when you are near your laptop or in your car will add hours to smartphone battery life.

A Ford rep at a CEA event ~2 years ago said car makers are working on console surfaces that double as chargers. We just need a standard!

It is much ado about nothing, IF you have a nice benign environment.  Make it nasty like the stuff military hardware has to endure, and then an environmentally sealed charging method suddenly looks very attractive from a reliability stand point.  Connectors are the number one failure mode of almost anything electronic. Period.

If you want to see resonant proximity charging on a much larger scale, surf on over to http://www.witricity.com and see power transfer into the low kW range for EV's.  We are currently working with WiTricity on an adaptation of their system for an autonomous military system in a harsh environment. 

As this technology matures, it will become much more prevalent.  Consumers will pay for convenience.  They always have and always will.

I'm with DrQuine. If you can't find a power outlet to plug into, why would one expect "charging pad real estate" be more plentiful?

Everyone has to make a buck, and perhaps this wireless charging will become a big hit. But quite honestly, it's a waste of energy and not exactly must-have.

Of course, if you talk about the difference in cost between an outlet with an extension cord and a pad, the argument for using wireless charging at home loses. But when your smartphone battery barely lasts for a day, you do sometimes wish if you could "tap it off" -- just in a few minutes -- some place in public so that you can call someone.

Indeed, using wireless charging in one's car is a good example.

General Motors is reportedly planning to build the smartphone charging technology into a handful of its automobiles.

GM is an investor of Powermat Technologies (the supporter of PMA standard).

With Powermat integration, some GM 2014 model owners can leave cables at home, and instead, simply place their phone on a Powermat-enhanced surface for a battery boost.
