Since Cobra lists no such model, hard to say, but... if it's like all the other LI XXXX series, 2 watts. Very few of the bubblepack radios have more than 2 watts, since they're illegal to sell in Canada if they are over that. Most are 1.25 to 1.9 watts.
If they ran higher power, the tiny little power packs they use would die in an hour.
If you actually want to find out, post the FCC ID number you will find on the back of the radio, possibly under the battery.
