Just wondering if these are any good ?? Black Ridge Generator 800W Inverter

I would think a 2.1 litre single cylinder engine would be subject to a little bit of vibration:-)

The 64db rating is fairly noisy. The Hondas and Yamahas are in the 45-50 db range which is a big difference.
A yamaha 1000watt is 50cc ,so the 2.1 litre is a mistake.

Other cheapies have claimed to have pure sine wave invertors and have destroyed equipment.The warranty does not include that.
The cheapies often suck juice at a heavy rate.
The 800 watt rating usually means a its good for about 650 watts

You didnt say what you want it for ,but as a camping generator its going to be fairly limited as to where and what you can use it for.

If you dont want top of the range ,get a Kipor which is establishing itself as one of the better chinese jobs.

If your patient,barely used Hondas and Yammys come up for sale in various classifieds at good prices.
I heard of one owner who claims 7000 hrs from his Yamaha.

P,

Consider the noise level carefully. For every 3db increase the noise doubles.

A two stroke chainsaw puts about 100db and can be heard for miles. A 1000 watt Honda/Yamaha/Kipor Generator puts out about 50db and makes less noise than people chatting in the next campsite.

64db is not quiet in the bush. I guess it depends where you camp. Some people are very sensitive about generator noise.

Cheers,

Jim.

Thank you everyone for the info and knowledge. Plenty for me to think about
