Wow! You really carry a 200W transmitter on tour? That is pretty extreme.
I go to the other extreme. I carry a smart phone and usually leave it turned off except for a few minutes a day. I could probably go a week on the half ounce battery in the phone with careful use. Also, it wouldn't be the end of the world to run out of battery. I do carry a little 2 AA blinky tail light and a 0.2 oz eGear Pico flashlight, but those typically last me for months on tour with only the batteries in them.
My guess is that most folks are somewhere in between us and miles from either of us in their battery usage.
