COVID-19 Emergency - Using UV Lamps to sanitize Face Masks overnight
KaneTW:
UVC LEDs are like 2% efficient, and that bag claims to use 10W (5V/2A). .2W of UVC is way too little to get germicidal action on a surface in a reasonable time frame. Batteries will die before it does anything.

Of course it's a scam. The website says they're an American company, but I doubt it.

Perhaps a prominent YouTuber such as Dave or Big Clive, should do a video on this.

I wonder why they don't salvage flyback transformers from discarded CRT TVs (should be fairly easy to find a lot that still work due to the sheer number) and just use an arc as the UV source. It would also generate ozone, so it would even be dual action sanitation.
That said, I'm getting the impression masks are a lot easier to get now and just having a bunch of them to rotate through would probably be the easiest solution.
Simon:
You just wash the masks and have a few.
