Google Nexus Gets Wireless Charger 223

Posted by timothy from the just-lay-still dept.
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."

        The most likely part of a connector to wear out are the springs - which is why in the MicroUSB standard, the springs are in the plug (e.g. the cable) and not the socket.

      • May not look like much now but it's baby steps like this that makes these kinds of technologies eventually become much better. If they don't start somewhere there will be no R&D money to continue and improve.

        The long term objective would be to enter your house and the darn thing starts charging regardless of where you are.

        • For that to happen, the charging would have to be via beamed RF energy instead of magnetic induction. What I'd rather see is a return to devices that only needed charging or battery replacements once per month or so. Like the old 2-way pagers I used to carry.

            At low frequencies or short distances they are almost the same thing. "Near field" is within about a wavelength or two, which at 30 Mhz is about 10 meters. So there's not really a hard cut off between induction and RF, more of a large gray area where you can say "this range generally behaves more like an inductor".

Each usb female socket is basically a sheet metal shell that's locked together by overlapping metal. There is no reinforcement of that shell. Every single time after a year of constantly plugging in the cable, the force of doing so bends the metal shell allowing the cable to have some wiggle room. That wiggle room allows all cables regardless of the springs to slip and not connect
