Actually a 5V, 2A wireless charger is innovation.

not for me

Wow! 5V and 2A!
Powerfull and economic!

so is it actually as good as wired charger?

As good as a very good wired charger. iPhones and most phones still ship with a 1A charger/

Depends which wired charger
This one is 5V and 2A, which is 10W
So for comparison
10W (5V*2A) = This one
5W (5V*1A) = iPhone charger
10W (5V*2A) = iPad charger
6W (5V*1.2A) = Nexus 5 charger (average for an Android without Quick charge)
10W (5V*2A) = Quick Charge 1.0
15W (5V*3A) = Quick Charge 2.0 (I think mainly for phones)
27W (9V*3A) = Quick Charge 2.0 (I think tablets only)
36W (12V*3A) = Quick Charge 2.0 (I think tablets only)
I wouldn't call it innovation since 10W Qi chargers aren't new
But its not bad at all, its as fast as iPad & Quick Charge 1.0 chargers
Only Quick Charge 2.0 is faster

Higher voltage/amperage of wireless charger will contact heat issues for battery and semiconductors.

Yep, the same happens with wired chargers
That's why phones and tablets use different chargers

You're forgetting not all the power transfers to the device, some is lost. The Qi Standard isn't perfect. They even mentioned it in the article.

Same with wired charging
There is always energy lost as heat
But you are right in that there is more energy is lost in wireless charging, since wireless charging does create more heat than wired charging
So yea, your right, a 10W wireless charger would charge slower than a 10W wired, my bad on that part

Been thinking people will be hogging to charging pad rather freedom with wired charger.
Not all people can leave their phone while charge, unless they sleep.

QI wireless pad inputs are DC 5V/ 500-2100mA. I have one Koolpad brand, it not innovation. S6 will combine different wireless standards. There is innovation.

Us carrier more likely will make us buy it instead nice enough and just come out of the box.

I'm pretty sure this would drive up the price of the actually phone. Then people would complain about the price.
