Wireless charging: inductive or conductive?

0. phoneArena 16 Feb 2011, 00:58 posted on

Wireless charging was introduced 3 years ago, but still hasn't really caught on; its adoption has been hindered by the split between inductive and conductive chargers, and the unsightly but necessary aftermarket backs...

all i can think of is more accessory and need new ones every time similar to the power mat thingy

The time it takes to plug in my phone, is a second or two longer than setting my phone on a mat. Why spend a $100 on a gimicky charger when a $15.99 one will do? At $15.99 i could have on in every room of the house... Now if my phone would charge from any place in the house without a mat to set the phone on or cord to plug in, that would be another story, a very Tesla like story.

The advantage that I have seen from the touchstone or the powermat is the benefits from not plugging it in. How many people have damaged thier charging ports from trying to plug it in late at night, or while inebriated. If the charging port is damaged, the phone is beyond repair, making it very costly. Without plugging it in all the time, consumers save the pain of breaking the charging port.

I think it's important that these guys decide on a standard. The inductive Qi standard makes more sense to me as this should be compatible with multiple devices. Also, it's important that OEM's embrace this tech. I don't want to buy a different powermat for every new device I get, also I don't want to have chunky back covers on my phones that I can't re-use one a different or a new model!

Next thing they should consider is wireless synchronization, perhaps using NFC, or bluetooth something..

Another possibility is to include some streaming tech for video or audio.

If you are going to rewrite the WSJ article please get it right. PowerMat uses inductive charging NOT conductive. It does requires it to be in a specific location on the charging pad. Please stop writing on subjects you obviously know nothing about or at the very least read the entire article you pulled this information from.

Reading so much so about the good think on the wireless charging.
HOW about it's impact to HUMAN body, especially electromagnetic field and frequency interference??????
Did any manufacturer come out with any kind of safety limit???

Whats the point of "wireless" charging if it needs to be so close to the "mat"? And what about energy efficiency? Does it cost more energy to charge the phone compared to direct conductors? -- I would think so, and thus cost more to charge your phone in electrical standpoint.

The only advantage i can see is that if the tech is deployed to high-tech cafes where the tables are themselves charges for people on the move.
