I have tried wireless charger before but you can't still go away from it. I hope they can invent something like the wireless network so even if you go anywhere around wifi area you still get to charge you phone too.

Unfortunately the laws of physics say otherwise. The simple fact is the further away from the source you get the more power it takes to get the same power at the receiver.

So if you put in 10 watts to transmit 5 watts over a 1 inch distance to get that same 5 watts at 10 inches takes about 10 times the power and so on so just to get a 5 watt charging signal for one device in a room the transmitter would have to putting out a kilowatt or more of signal.

How many devices that take only take a few watt hours of power to charge can you afford to pay for on your electric bill if to charge them takes several kilowatt hours worth of electrical power each to do it?

Is being able to walk into a room and have your cell phone or any other device automatically start charging in your pocket worth several tens of cents per hour 24 hours a day? (~$150+ a month on your electric bill?)
