Some may think going for a power generator with starting wattage of around 12000 watts is a must for 50 amp RVs. But it isn’t. A generator with such power can be expensive and unnecessary if you don’t have too many appliances to run.
So what could be an economic generator for your 50 amp RV? Check out the super-economical XP8500E model from Duromax here. This gas-powered generator provides an amperage of 36.6 amp, which you may think is a matter of concern for your 50 amp RV.
But you can easily resolve it using an adapter. Its 120V/240V electrical system and wattage rating (8500 starting watts and 7000 running watts) are perfectly suitable for your 50A motorhome electronics.
Apart from using the adapter, it sets you right up regarding the assembly. The box includes a toolset, oil funnel, spark plug wrench, dc charging cables, wheel kit, handle, and an instruction manual. So you can assemble and do the whole installation part easily on your own. Simply, add oil to get started in no real-time.
In terms of fuel efficiency, the recently integrated Auto Throttle or Idle Control technology appears to operate well in terms of maintaining RPM under various loads in order to improve fuel efficiency. Its run time is pretty much close to the claimed 11.5 hours even after running common appliances at 50% load. There’s no eco-mode and probably not required as well.
The electric start is convenient, while you also have the pull-string start as the second option. It’s completely RV-ready with a range of 120V AC outlets(four) and 120/240V 30 amp twist lock outlet (one). But you’ll need an adapter to use it for your 50 amp RV. There’s no parallel ready socket as well. Duromax’s exclusive MX2 Technology helps draw maximum power from each of its receptacles.
It seems well built with high-quality steel. The compact footprints, wheels, and handle make it pretty convenient to maneuver and transport. The inclusion of a 50 amp RV outlet could’ve improved its value.
Its major downside is the rattling noise(72 dBA) and a not-so-convincing warranty or after-sales support. DuroMax should look to improve it.
