well mine puts out about 3-3.6 watts depending on where you are on
the band.. it is not turned up all the way and it seems very happy
and performs super.. this is off a only-partially charged 4ah gel
cell and has been running for hours and hours without having to
recharge the battery.. kinda wanta see how long it will go.
