Rated 5 out of 5 by from Great for camping First time out had 3 people comment on how quiet this generator is and what kind was it. We can have a quiet conversation sitting right next to it. I am very pleased with its performance...more than adequate power to keep everything running. Highly recommend it.

Rated 4 out of 5 by from Pleased, so far The inverter does everything it says it will. I'm having a bit of an issue with it holding a steady idle, which I attribute to an after-market tri-fuel conversion kit. It's a very simple design mechanically (no fuel pump or even filter) so there is not a lot that can go wrong. The unit is not that heavy and is very easy to move around. I'm planning to use a siphon hose to change the oil, Finally, while the unit is quiet, the exhaust is rich with fuel, Perhaps this is causing my idling issue- I don't yet feel like taking the entire thing apart again to find out. I'll update this review in the future if there is any issue with the inverter itself.
