New wireless charging gear promises 3x faster charging

Freescale logoFaster charging, like Qualcomm's "Quick Charge 2.0" (branded as "Turbo Charging" on the Nexus 6), is one of the nicest new smartphone features available. If we can't make a battery last all day with heavy use, we can at least make it charge faster. The faster charging is possible because these devices charge at a higher wattage—instead of the normal 5 watts from a standard USB charger, these hit about 14 watts.

These faster chargers have left wireless chargers in the dust, though. Today's Qi charging pads still only put out 5W, the same as a slow wired charger. Freescale Semiconductor, a company that provides various chips to OEMs, is out to fix that. Today the company announced integrated circuits for 15 watt wireless chargers—a wireless solution that should be just as fast as a hardwired turbo charger.

Of course, you will need new hardware to make this work. Freescale's solution will require a new chip in your smartphone or tablet and a new charging pad. The good news is that this isn't a new standard. Freescale's chips can be tweaked to be compliant with Qi charging, which is found in many smartphone, or with lesser-used standards like the Power Matters Alliance. The Qi "medium power" standard is actually good up to 120W, provided the pad and device support it.

Freescale says its 15W chips are an industry first, and the company hopes to keep pushing the wireless wattage higher and higher. Eventually the company hopes you'll be charging laptops, cameras, computer mice, keyboards, and even appliances wirelessly.

Freescale is just a component supplier, so it's not the right company to ask about end products, but its chips and reference designs will be ready for OEMs in Q1 2015. Just like Qualcomm's "Quick Charging," branding will be up to OEMs too, so if you start to see a bunch of wireless chargers with "turbo" or some other "more speed" branding, it's probably just a 15W version.
