Wireless charging is starting to become fairly commonplace for those of us with mid-range and high-end Android handsets, with QI charging quickly becoming the standard of choice. With wireless charging, there’s no need to physically plug a cord into your device each time you want to charge in, instead you simply drop your phone onto a compatible charging pad and that’s that. Of course Qi’s inductive charging technique means you have to make sure you are aligned just right, or your phone won’t actually charge.

Wouldn’t it be nice if we could place our phones and tablets near the pad without having to worry about positioning or placing it directly on the pad? That’s exactly what Qi version 1.2 will bring to the table. Right now, the Qi standard can wirelessly transmit to a device that is up to 7mm away from the transmitter. In other words, you have to place it exactly on the right space. With v1.2, this bumps up to 45mm, or 1.77-inches. This means you no longer have to directly touch the pad, and it also makes it easier to create pads that hold multiple devices and the list goes on.

As for those with devices that are designed with Qi 1.1 in mind? These devices will still play nicely with version 1.2 chargers, though the range will be slightly less at 30mm. It’s also worth noting that Qi 1.2 could take the standard to larger gadgets and some smaller appliances, as it will now be able to blast 2000 watts of energy.

The first Q1.2 chargers and receivers are expected to arrive a bit later this year, with the standard set to hit small appliances and other devices outside of the mobile world in 2015. For even more details, be sure to check out the Wireless Power Consortium’s official announcement PDF. Do you currently use wireless charging for your mobile device, or are you perfectly content plugging in your phone the old fashioned way?

    I have three wireless chargers. Two at home and one at work. I don’t think I can go back to cables. But my wireless charging days started way back with the Palm Pre Plus. :)

      If people gave Tesla more credibility, you wouldn’t even ever use a wired charger.

      great and super underrated phone

    As long as people don’t stack phones on top of one another. That’s a recipe for disaster.

      I hate the idea of stacking phones. I cringe whenever people do that in video reviews to compare thinness. lol

    For me Its wireless or nothing. Its a real problem fro tablets as only Nexus seem to implement it and I like 8″ tablets. Here’s hoping for e 8″ 16:9 2k screen, Tegra K1, 64gb Nexus tablet with wireless charging and a unicorn skin cover.

      I know I already mentioned a webOS product already here lol, but tablet makers need to take a look back at the HP TouchPad and it’s wireless charger. I dont know why no one has done wireless charging like that for tablets since.

    I’m waiting for the day when I can just put my desktop anywhere in the house and it’ll get electricity without wires (and while we’re at it,10GB (not small b) per second download speed anywhere without wires)

    Very glad this is backwards compatible. I always envied A4WP for its resonance charging. Now I get some without having to buy a new phone.
    Want to try and fit a charger into my car next!

    2kW, huh? I know it says for kitchen appliances, but that is still quite a lot. At 5V, that would be 400A, which is enough power to charge 200+ Nexus 5’s simultaneously.

    Hoping to see a high quality v1.2 car holder & charger soon. The Nokia NFC & QI holder is great, and the quality is exeptional – but the coil placement combined with the holders bottom support tab, makes its compatability with other phones a hit-and-miss affair.
