Mobile device manufacturers are always looking for the latest hot feature to capture the public’s attention. Over the past few months, we’ve seen several efforts to draw shoppers’ eyes to the notion of fast charging – power adapters able to push so much juice into our phones that we’re charging them to capacity in a matter of minutes, not hours. And while that’s all really great, it’s not doing much to help promote another big power-related tech: wireless charging. Sure, wireless charging can be quite convenient, but it’s also a bit slow. However, that may soon be changing, as solutions are soon to arrive that seriously bump-up the amount of power that can be powered to our devices wirelessly.
Freescale Semiconductor has just announced a Qi-compatible charging system that triples the regular 5 watt Qi max output to 15 watts. That’s the same level of power you’ll get from something like the Motorola Turbo Charger.
For this to work you’ll need Freescale’s chips on both ends, but even when an appropriate receiver or transmitter is absent, it can always fall back to the regular Qi 5W output. It’s even compatible with PMA-based systems (if that’s the side of the wireless charging fence you find yourself on). The need for special chips on both sides may limit just how ultimately useful this is -unless Freescale can make a major push to get its components into popular devices- but it sure sounds like a step in the right direction, keeping wireless charging relevant in an evolving landscape.
The system should become available in the first quarter of next year, so it’s conceivable that we could see phones and tablets using such 15W wireless charging sometime later in 2015.
