Review on 🔋 Samsung Qi Wireless Charger and UV Sanitizer - US Version: Keep Your Device Clean and Charged! by Brandon Vox

Bought mine direct from Samsung. The design is great and seems to fit. However, we must understand the limitation. Summary: 1. It appears to emit enough UV radiation to kill bacteria and reduce the virus from 90% (1 log) to 99% (2 log) under ideal conditions.2. But the UVC intensity seems weak according to the dosimeter card test.3. The raised ribs on the underside do not raise the object high enough to allow UV light to show through. This. Only the side facing up is effectively disinfected.4. Using a disinfecting wipe is probably more effective and can be done in seconds. Disclaimer: I'm not an expert on UV disinfection, but I still want to share my experience testing a device with a dosimeter that changes color depending on the intensity of UV radiation. Try Samsung UV sanitizer, I used UVC dosimeter cards. The initial color is yellow when exposed to UVC it changes to orange indicating a UVC dose of 50mJ/cm2, when it changes to pink it indicates a dose of 100mJ/cm2. (50 and 100 are guidelines, used in medical facilities). Test card up: 1 cycle (10 minutes): no color change 5 cycles (50 minutes): orange (ie 50 mJ/cm2) 10 cycles (100 minutes): pink (ie 100 mJ/cm2) (Possibly incorrect) Based on the above, d. 5 cycles for a dose of 50 mJ/cm2, I have calculated that 1 cycle (10 minutes) gives a UV dose of around 10 mJ/cm2. From my online search, many common bacteria and viruses can be reduced by up to 2 log (99%) at around 5-10 mJ/cm2. Dose. At a dose of 50 mJ/cm2 to 100 mJ/cm2, disinfection for most bacteria and viruses can drop to log 3 or 4 (ie 99.9% - 99.99%). Therefore, Samsung's claim of killing up to 99% of bacteria seems unfounded. To the right. However, this is only possible under ideal conditions, ie if your product is free of dust, lint or other contaminants that may block UV rays. For this reason, the higher values of 50mJ/cm2 or 100mJ/cm2 are recommended in the medical field. is on the bottom. There are some protrusions on the underside to elevate the object to allow the UV to (theoretically) show through. When tested with the dosimeter test card facing downwards: does not change color even after 10 cycles (100 minutes). I have yet to run enough cycles to change the color looking down. As mentioned, the disinfectant has several small protrusions to lift the item by 1 or 2mm. But that's probably not enough for UV light to shine through the underside. So I can't estimate the dose he's giving per cycle looking down. but sure it is very low compared to open. Basically I am satisfied with the product. With relatively low UV radiation but at an affordable price I would give it 4 out of 5 stars. Another star is deducted because only the side facing up is effectively disinfected. Therefore, you need to turn the phone over at least once (the disinfected side can be re-contaminated because you can touch both sides of the phone when you turn it over). Assuming you've done everything carefully, it still takes at least 2 cycles (20 minutes) to disinfect both sides of the phone. Remember, disinfectant wipes can result in a 99.9% reduction (3 log reduction) and can be done in seconds. Wireless charging is nice. special feature. Small items such as headphones, keys, etc. work perfectly. But the container is too shallow, most sunglasses are too thick (such as bent okley) to fit in, which limits their use. primary disinfection method.
