Now, whether it works or not depends on the dose, and that is only partially related to the power of the source and the time the target surface is illuminated. https://www.americanair
The short answer is that we don't know the spectral efficiency of the lamps or the wattage for this device, so we can't even begin to determine what the average dose would be, much less the specific dose on the various parts of a phone from the two sources at the ends of the cavity (it can be calculated with raytrace techniques or with hand approximations, but will vary by phone geometry). The only thing we do know is that it's a 600 second cycle. You can't use the "output" from my link in the previous post as data is wrong - they claim a 2000uWs/cm2 value, but that's like claiming how loud a sound is, in dB, without knowing how far from the source you'll be. All I can say is that, based on other 253.7nm tubes, the total power emitted is going to be less than 3W, and probably less than 500mW. The interior of the case is around 500cm2, and I'd be surprised if the view factor to the middle of the case was 0.01 with a phone installed. 500mW x 600s / 500 cm2 * 0.01 = 6mWs/cm2 or 6000uWs/cm2 or 90-99% efficient. That answer is wrong, btw, because of all the assumptions I made. Taking the low end, you should run a phone at least 5 cycles to consider it clean for common, every day viruses and bacteria (99.999 - 5 log dec - is usually considered decontaminated, though some people say 6, see my disclaimer). Taking the high end, 1-2 cycles is good. In fact, the top and bottom ends of the phone will easily get this...it's the middle we're worried about.
Disclaimer: I'm not a virologist or epidemiologist. I'm an aerospace and structural engineer with formal training in radiative transfer and fluid flow, with practical, professional experience in optics, spectrometry, material science, and structures. What I *can* say is that the information above is how an engineer would approach a device made to kill microbes with EM radiation and the numbers are probably not too far off. It's not rocket science, but it's not as simple as calculating mileage or paint coverage.
1. The UV production is from 4 fluorescent micro-tubes, two at each end - or maybe a U-shaped, not LEDs. It's not the same as the UV tube in my phillips toothbrush (E17). Best guess is it's something like this [diytrade.com]. Based on the opaque interior, I would guess that what ever side you place face down (back side for charging) gets a relatively low dose, as would the middle of the top side (screen).
2. The box volume is very large, and easily fits my iPhone 13 Pro Max with a Spigen Tough Armor case (3-5/16 x 6-5/16 x 9/16). Best I can measure, an item which is 3.75"x7.5"x1.1" will fit with the lid closed
I've not really had a chance to play with it or otherwise test the output.

you have to flip the phone every 5 minutes - as it only "cleans" one side at a time
but if you ever find the "phonesoap" device on sale .. you dont need to flip
the phonesoap was on sale months ago at $12-$18 is a better deal IMO

This is ultraviolet light, which is towards the opposite end of the spectrum from infrared- short wavelength, rather than long wavelength. That said, yes, UV light will absolutely kill germs, given enough of a dosage. It will kill most anything, given enough of a dosage!
