Boliy versus Champion: Boliy vs Champion
Very comparable with some things favoring the Champion but the larger fuel tank on the Bolily is whey I chose it plus newer Boliy's have option of a plug in marine fuel tank for even longer times before refueling.
The seller appears to be biased towards the Champion and I think his profit margin on it is higher. I don't really care or need a trickle or USB port on a generator...that's kind of silly since my generator is usually put 25-50 feet away from my camper so we can barely hear it. The Boliy's battery is kind of weak and good for 2-3 starts only so make sure you have your fuel on and choke on before you attempt electric start-pull start is very easy and starts on 2nd pull when cold.
The champion has 2 120 volt outlets----who cares, I'm only hooking up to the generator with the 30 amp RV outlet plug/cable....
Not sure what the trickle charging feature is on the Champion which the Boliy doesn't have....but never needed this feature as far as I can tell. The Boliy does have a 12 volt output that can be used to charge dead 12V batteries directly if needed.
You can't go wrong with either the champion of Boliy but I favor the Boliy becuase it has served me WELL for many many hours and years. All I have done is change the oil and clean the spark plug once a year.
I use 5w40 diesel oil which has high detergent capability and does better job protecting engine that has no oil filter (none do that i can tell)....being a diesel oil it is designed to suspend soot and crud.
