Reviewer: Alan Woods from Pollock, ID United States  
Wanted gen to charge boat and camper batt. with dc outlet. Very fast shipping. Fired right up after installing oil and gas. Ran for 4 hours tested with drill with no problems.  Also wanted to be able to run at higher allitudes, currently jetted for up to 4000' but can rejeted for believe up to 7000 feet. Cheaper gens don't have that option.  Found that Hondas are a little more and don't come with charging cord. Also own 3 Yamaha 4-whellers and 1 snowmobile that I have been happy with.
