The pathway to innovation is paved with failed attempts to produce wireless charging solutions that a) actually work and b) people genuinely want to use, but we've got yet another upstart here at Mobile World Congress willing to give it a go. PowerbyProxi's solution looks pretty similar to renditions we've seen from Fulton Innovation, but it's quick to point out the differences. The loosely-coupled method uses a bantam receiver that's "efficient enough to be integrated into the processor board of a smartphone without causing over-heating."

While previous industry designs have resulted in longer charging times than if the device were plugged into a wall socket, PowerbyProxi's solution reportedly "provides charging at the same speed as wired charging." In fact, it claims to offer the only system that can rejuvenate up to three devices at the same time at full power. If you're wondering what working group these guys are going to side with, that much is still up in the air -- it's remaining "agnostic towards the selection of an ultimate standard" for now.

We spoke with the company here at Mobile World Congress, and it confirmed to us that it's working with the top five major battery manufacturers, and we should see wireless AA and AAA cells "within 12 months." It wouldn't confirm how soon we'd see it in phones, tablets or laptops (yeah, it'll work in all of 'em), but it's clearly working with some of the top OEMs and hoping for the best. In the demo we witnessed, specially equipped Galaxy S III handsets charged alongside one another, even when barely clinging to the charging pad. Despite a bunch of metallic objects being heaped on the pad, it was intelligent enough to only send power to the phones, keeping gum boxes and coins cool, calm and collected. Head on past the break for quick video tour as well as a press release.
