parts manual

Can’t find a parts manual anywhere. I need to replace the side enclosure panel. Other than that it seems to be working fine. Just need to go camping and try it out

Has quality written all over it!

Added the oil and gas, started first pull! It also is so very quiet! I am looking forward to many hours of top performance from this little generator.

Great camping unit!

Pick this unit up for camping/boonedocking and was pleasantly surprised by how quiet it is. Generator/inverter is just what we needed, super light with great run time.

Fortunately...

I haven't needed to use it yet. But I added the oil and gas and it started on the first pull! I've started it several times since and let it run for an hour each time and it works just fine. Couldn't ask for more!

Disappointed

I thought the peak power would allow my generator to start my AC unit but it did not.

Best silent generator ever

Extremely silent for the power! Love mine and never got faulty. Easy start and last long on eco mode.
