The most common max power on a new radio is 100 watts, although some of the more expensive radios could have more. With the stock 100 watt radio, depending on atmospheric conditions, your antenna type, and the height of your antenna, you could talk to most all countries, but not on demand. What I mean by demand is that you can't control when you will make each contact, but each day, or night, you may contact some part of the world.
Watts are amount of power used, and is figured by mulitplying the volts times the amps. So if a car is using 5 amps, at 12 volts, to run the headlights, it is using 60 watts of power. (5 x 12). But most people think of batteries as amps and volts only, hardly ever think of watts. Headlights are rated at watts, such as high beam 55 watts, low beam 35 watts.
