Confirming it's the white transmitter box from early 2018

Seems they had the "new" transducers on display at the public event, weirdly. I have no idea why they'd show those off. The LED unit shows that the focus is fairly large. I'd be interested to see that swept around while the focus is kept in the same place to see if there are grating lobes.

StillTrying:
It looks more powerful with that LED board at that distance, stick on light bulbs are now only 4 or 5 orders of magnitude away. :horse:
distance x20, power x40, efficiency x40.

The interest in the whole at a distance wireless charging business seems to be close to zero, even for wi-charge who seem to have a working IR system, they had their 2 trains at CES2019. They're all moving to IoTs and smarthome where there's even less interest than distance mobile charging. :-DD

Notice how far down the list you have to scroll there before you find anything from uBeam? No, seriously it's a question because I scrolled for about 10 minutes and found nothing. It'll be interesting to see if the new CEO moves the PR bandwagon much closer to that of Energous and Ossia. Speaking of Ossia, they're really pushing their phone cases, which is interesting because as far as I can see they don't even have an FCC ID with which to apply for Part 18 approval. I'm wondering if they're going to pull a "we only supply the component, it's the final product vendor that has to get regulatory compliance".

Powercast are the only company that I can see that meet existing regulatory and don't lie about capabilities, hence the micro to milliWatt limits. WiCharge are interesting and seem more open, but efficiency won't be great and it's the safety of Watt-level lasers that gets me concerned.

If you were especially looking for ubean you could have saved 10 minutes by searching for both words at the same time!
The first 2 are.

I search for ubean about twice a week, there's been nothing happening for quite a long time, people no longer ask when their cable-less home or office is coming or when can they charge wirelessly.

There a few threads here on WiCharge if you've got lots of time to waste.

I think WiCharge's 2019 predictions are just hopeful wishing.

I don't know much about Ossia, they seem to be determined to make Wi-Fi unusable. :)

I know, I was just both being a bit obtuse, as well as lazy - writing anything about them is more effort than I really should be spending on that company.

On Ossia, someone from a bluetooth-enabled product company chatted with me after CES and Ossia's presentations. Apparently Ossia are claiming 2 to 3 Watts delivered to a device battery within a car interior (re-asked and reconfirmed). While on the one hand they are saying 5.8GHz, they are doing demos at 2.4GHz, and this manufacturer was concerned about what it would do to his product. I told him not to worry about his product, his eyeballs are a larger concern. Ossia's public materials don't give numbers so this is just word of mouth. They do make some ridiculous statements though - here's their founder going through the maths of why you're better building your house with wireless power rather than those expensive wire things. Apparently it will be cheaper, save the environment, and make us all safer if we just change to RF wireless. Not sure how the wireless emitters get their power...
