Hi i believe its 1 W as a max output when the settings are set to high it doesnt state on the radio what it would be i just remember reading somewhere its 1W and i believe that aslong as the radio can be programmed the programming cable works ! I have programmed all my radios with this one cable

@@cwhatimdoing Ok thanks for the answer. I was thinking that the RT622 is the European version of the RT22 US version and that one got 2W and they are both identical i think and the only differens is the watts.

@@cwhatimdoing I just sent an email to Retevis and askes how many watts the high setting is. I will be back as fast as they get back to me.

@@Jakelol1980 sounds good to me I swear somewhere i read 1 or 2w but i alos guess that asks the question of how long will the battery life be outputting on 1w or 2 as this could be either 2 or 4 times the standard power output

@@cwhatimdoing Yeah the battery life will be a lot shortsen for sure but if i get 2W instead of 0.5W Im happy even if the battery life is like only 5 hours.
