Yamaha 3000iSEB......
We chose this unit for features, price and portability. It was purchased through Mayberry's, no tax, free shipping. They "verbally" advertised the boost as up to 4500 watts with continuous of 2800......We use the inverter at night and recharge during the day, usually every third day, takes about 5-6 hrs to crank the 4 T-105's back up to full charge.
The only down side to a portable of this size is weight, at 150lbs it is a pita to load and unload. I use an engine hoist to accomplish these tasks and leave the unit in the truck in camp. I use a full plastic smoker cover to keep it out of the weather......great unit............
Mayberry's no longer sells Yamaha units.....................
