The FT-891 can transmit at 5w, but as you'll see from statistics, you may as well be transmitting at 10w, or 15w, because you're really not saving much by running QRP.Getting off track here -- I recently purchased an incredible Lifepo4 12.8v, 10Ah battery with massive 20amp current draw, and I'm in portable heaven with this rig

It can also function as a strong SSB portable option, provided you bring enough battery, and maybe a voltage meter, if you feel you need one
