Google Nexus Gets Wireless Charger
judgecorp writes "Wireless charging has had little success so far (except for toothbrushes) but Google is giving it a good try, with a Nexus Wireless Charger that works with LG's Nexus 4 and 5 as well as the latest version of Google's tablet, the second generation Nexus 7. The charger operates using the Qi standard, which seems to be ahead of rival Powermat."
You magnetically drop your device into place onto a block on a power cord. Instead of plugging the power cord into your device. The actual distinction in convenience is a half a second of fiddling per day.
Google already sold a wireless charger for their Nexus 4 phones:

I own one, works fine, and I think it also works with the new Nexus 5's as it's using the Qi standard already.
I just ordered 5 wireless chargers for a grand total of $85 as stocking stuffers for my family members with Nexus 4's and Nexus 5's.
I think they came from China since they're just being delivered today. Reviews of them on newegg were good. We'll see.
I just can't see spending $50 on a charger unless its the size of a mousepad and can charge multiple thins.
I don't really need wireless charging, I'd be happy to drop my phone into a dock with pogo port pins to allow easy charging without connecting a cable (and without wiggling the phone to get it to seat on a microUSB connector in the bottom of a dock). Seems like a cheaper and easier solution than wireless charging.
Why didn't more phones use that simple technology? I never did find a compatible dock for my CDMA Galaxy Nexus.
I've checked a few places and it seems as though you can expect a 70% power efficiency with this type of inductive charger. Some of the higher end models reach as much as 85%.
It strikes me as odd that in a time where we want as much energy efficiency as possible, we'd push towards something much less efficient with the potential to be so widespread.

That wasn't one of the times. 1 or 2% efficiency for power transmission is unacceptable. Pneumatic power was better then that. Whale oil lamps were better then that.
He could never have proven it. Period. It did not work in a practical sense. It can never work.
You can beam power, if you build big fucking antennas at both ends.
If you could build a magic transmitter that didn't radiate into the sky, you'd still lose intensity with the square of distance. Field intensities strong enough to power a house could also start fires on things like aluminum window frames.
