Powercast Corporation, the pioneer of radio-frequency (RF)-based long-range power-over-distance wireless charging technology, announced that it will unveil at CES (booth #40268) its FCC-approved (Part 15, FCC ID: YESTX91503) and ISED-approved (Canada IC: 8985A-TX91503) three-watt PowerSpot transmitter which works in the far field (up to 80 feet) for over-the-air charging of multiple devices - no charging mats or direct line of sight needed. Powercast used the experience it gained powering industrial and commercial devices with its initial Powercaster transmitter (FCC and ISED approved in 2010) to develop the new smaller, smarter and less expensive PowerSpot transmitter specifically for the consumer market. The PowerSpot is the industry's first long-range, far-field, power- over-distance wireless recharging transmitter for consumer devices to gain FCC and ISED approval.


How Powercast's patented remote wireless charging technology works:
Creating a coverage area like Wi-Fi, a Powercast transmitter automatically charges enabled devices when within range. The transmitter uses the 915-MHz ISM band to send RF energy to a tiny Powercast receiver chip embedded in a device, which converts it to direct current (DC) to directly power or recharge that device's batteries.

Powercast will begin production of its standalone PowerSpot charger now that it is FCC approved and is also offering a PowerSpot subassembly that consumer goods manufacturers can integrate into their own products. Consider lamps, appliances, set-top boxes, gaming systems, computer monitors, furniture or vehicle dashboards that become "PowerSpots" able to charge multiple enabled devices around them. Powercast is in discussions with several manufacturers, and has inked deals with two household names, since releasing a wireless power development kit in early 2017 containing the PowerSpot subassembly.

"Consumer electronics manufacturers can now confidently build our FCC-approved technology into their wireless charging ecosystems, and offer their customers convenient far-field charging where devices charge over the air from a power source without needing direct contact, like inductive charging requires, or near direct contact, like magnetic resonance requires," said Powercast's COO/CTO Charles Greene, Ph.D.

The company's vision is to enable long-range, true wireless charging where consumers simply place all Powercast-enabled devices for charging within range of a PowerSpot in their home or a public place.

"Others might be talking RF power possibilities, but we have consistently delivered far-field wireless power solutions that work, safely and responsibly, under FCC and other global standards providing power up to 80 feet," said Greene. "Our robust technology has capabilities beyond today's permitted standards, so our product releases will evolve as regulations do."

The PowerSpot creates an overnight charging zone of up to 80 feet free of wires or charging mats:
Enabled devices charge when in range, but don't need direct line of sight to the PowerSpot. Powercast expects up to 30 devices left in the zone on a countertop or desktop overnight can charge by morning, sharing the transmitter's three-watt (EIRP) power output. Charging rates will vary with distance, type and power consumption of a device. Power-hungry, heavily used devices like game controllers, smart watches, fitness bands, hearing aids, ear buds, or headphones charge best up to two feet away; keyboards and mice up to six feet away; TV remotes and smart cards up to 10 feet away; and low-power devices like home automation sensors (window breakage, temperature) up to 80 feet away. An illuminated LED indicates devices are charging and it turns off when they're done. Audible alerts indicate when devices move in and out of the charge zone.

The PowerSpot transmitter uses Direct Sequence Spread Spectrum (DSSS) modulation for power and Amplitude Shift Keying (ASK) modulation for data, and includes an integrated 6dBi directional antenna with a 70-degree beam pattern.

"We know consumers also want to charge mobile phones, so at CES, we will showcase a technology demonstration, developed with a partner, of a PowerSpot transmitter that adds the Qi inductive wireless charging standard adopted by many mobile phones," said Greene. "This combination would provide a best-of-both-worlds solution, operating within the FCC regulations that exist today, including RF over-the- air charging for multiple PowerSpot-enabled devices placed near the transmitter, and Qi proximity charging for power-hungry Qi-enabled mobile phones placed directly on the Qi charger on top of the PowerSpot transmitter."

At CES:
Powercast will demonstrate prototypes of its PowerSpot, 7.3" long x 2.1" tall x 1.4" wide, as well as wirelessly-powered game controllers, headphones, smart watches, earbuds, smart clothing, illuminated retail packaging, and reconfigurable retail price tags.

PowerSpot production units are expected in Q3 2018 for about $100 from distributors Arrow Electronics and Mouser Electronics. Once PowerSpot reaches mass production, Powercast projects a $50 ASP from major electronics stores or from consumer electronics manufacturers offering it as a charging option.

Pretty cool! One of these in my room and I can use my phone as long as I want without the need for an annoying charging cable I will trip over! Well, once they figure out how to get more than 3W out of it that is. Still a good gadget to have on your desk once devices get those chips.

I dont think we fully understand the benefits of "wireless charging". While keeping our phones are charged is great, it has the potential to drastically change everything we do. Imagine, the ability to transmit large amounts of power over long distances with only an antenna for infrastructure. It would completely reimagine construction projects and city development. Cars would just need an antenna to stay full all the time.

Energy density halves with the square of distance, no antenna will ever be able to overcome this, and for low current devices that we can make, it will be awesome, but for high current like cars, the transmitter would be so unsafe at any reasonable distance that it would become unfeasable, essentially these are unfiltered RF noise generators, but tuned to a specific frequency, and harmonics and impedence will result in high noise in other bands, which is why they are limited to 3W.

0.75 KW per horsepower. You're suggesting a lot of power through an antenna, per car.

And now for the trick question;

What is the frequency this thing operates on???

However awesome this is, and it surely opens wast new opportunities, I would be rather interested in what way these RF charging radiation (really) affects the human body, before getting one more radiation emitter in my home...

What? Are you suggesting that transmitting hundreds of kilowatts, if not megawatts, through the air might be a bad idea, and difficult to control? That's the silliest thing I've ever heard. It's not like lightning ever hurt anyone, after all.

There's a reason the PR here includes this quote:
Power-hungry, heavily used devices like game controllers, smart watches, fitness bands, hearing aids, ear buds, or headphones
These are power-hungry devices in the same way that goliath bird-eater spiders are large animals: it's all about context. A Dual-Shock 4 lasts around 4 hours on a 1000mAh 3.7V Li-Ion battery. That's a 3.7Wh battery, or a constant power draw of ~.9W to drain that battery in 4h. Compared to a TV remote lasting months on a CR2032 button cell, that's power-hungry indeed. Compared to a smartphone playing a game (3-5W), or a laptop in use (15-300W), not a lot at all. Compared to a vacuum cleaner (800-2000W), it's barely noticeable. Compared to a car? Don't be daft. Rather oversimplified, but a 200HP electric car would then need 150KW to operate at peak output. That's more than 40 000 times the power draw of their "power-hungry" device.

People, wireless charging will not replace high wattage use scenarios. This is great for phones and all but don't expect this to replace power lines. It's incredibly inefficient to convert electricity to RF and then back again compared to simply plugging the device in.

So, many years ago when we were all much much younger, my family went shopping without me, and when they came back, step-sis was taking a brand new toaster out of the box. She says, "Where's the power cord?" Now of course obviously (to me) the cord must be wound on the bottom of the toaster, but she wasn't that savvy. I said, "Oh, it's one of those new wireless toasters, just set it somewhere near an outlet." Fast forward a bit ... "MOM! The wireless toaster's broken!" "The WHAT?" hahahaha

I'd like to see this tech applied to power LED strips inside PC enclosures. 3W could be achieved by plugging a transmitter to an internal USB 3.0 header on the motherboard, but I'd think low power LED strips could be powered even via internal USB 2.0 ports. This would eliminate a lot of the clutter inside well lit cases.

Having the transmitter inside a faraday cage would also help to mitigate any potential issues with the radiation, but I'd think the FCC wouldn't have approved the tech if there was any major implications it would do any harm in the first place.

Given that most internal PC components are unshielded, that's a really bad idea. Even if this tech is certified in all kinds of ways, I can't imagine your RAM or PCIe signalling being especially friendly towards high-powered EMI noise. Remember, your motherboard traces are effectively a huge antenna array, and your case is the principal way of shielding them from interference.
