The light works just as described. One of the complaints that I’ve read from reviews is that it does not take rechargeable batteries. I don’t think any kind of batteries would last long or provide consistent power for this UVC light because of its quality and intensity. So… I did some research and found a 16.4 FT USB extension cable that works perfectly and enables me to use the wand in any room by simply plugging the USB extension cord into the end of the UVC Wand and the other end of the extension cord into one of my IPhone charging blocks that plug into my wall socket. (I use a 5 watt power block.) To find the 16.4 FT USB extension cord, enter B07CTHWQ1S into the search box on Amazon. The cost is $7.98 and so it’s a LOT cheaper than going through lots and lots if batteries.
