I've had a BAOFENG UV-8R, and according to several watt meters and service monitors, the maximum output is five watts. It's considered a "throw-away," so if it lasts a few years, then so be it. I've had it for 4-5 years (I think), and it gets the job done. Of course, I had to upgrade to a better antenna which cost more than the BAOFENG!
I don't have to worry about it, as I would with one of my Kenwood, Yaesu, Alinco, or Icom portable radios.
