Nice Generator

This is a great generator. It's one of the smallest propane generators available in California. I only just got the wheel kit assembled and a short 20 min run. It started flawlessly (the battery was well charged so no need for a pull start). I have only tested the 110v 20 amp outputs, but a 75 watt lamp didn't make the generator flinch. I look forward to a lot of good use from this unit.

Rugged Beastly Generator

Only took a few days to arrive. Very pleased with the quality! LP is so much better than just gas, and for me is easier to obtain. Thanks for the great generator and the versatility.
