You can safely use it with an RV. However, note that since it’s rated at 4000 surge and 3500 running watts it cannot be treated as a comprehensive portable power solution.

You will find it easy to start and operate thanks to the E-Z 1-Pull Recoil Cord.

It has a heavy duty frame providing the necessary protection from falls and some weather elements.

It has a maximum run time of 8 hours @ 50% maximum output.

Thanks to a built-in muffler it is not very noisy.

4. Great Value for Money – DuroMax XP4400E 4,400 Watt 7.0 HP OHV

While being significantly cheaperDuromax XP4400E portable generator than some of its competitors, Duromax XP4400E does it job very well.

Just like its cousin XP4000S it provides 3500 running watts – enough for jobsites requiring the use of such tools as grinders, drills or reciprocating saws.

The difference here is the higher surge wattage – it basically means the number of watts a plugged device needs when started. Pay attention to this number – it can often be significantly higher than its demand for running power.

Air compressors (1HP) are one such device requiring approx 4400 starting (surge) watts and the ongoing wattage of only 1600.

Duromax XP4400E provides just enough power to cater to one such air compressor.

Unfortunately, unlike XP4000S this generator is NOT CARB compliant.

On plus side XP4400E has a 4-gallon tank allowing for the total run time of around 8 hours on half load before it runs empty.

This generator has got several different types of outlets: 2 x 120V, 1 x 120/240V, 1 x 12V utility outlet and 1 x 30 amp twist-lock. These are definitely more than enough to cater to different kinds of appliances as well as RV.

Read more about the characteristics of Duromax XP4400E here

  • Cheap
  • Long running time
  • Easy to use
  • Several various types of outlets
  • Non-CARB Compliant – NOT FOR SALE in California

5. A Very Quiet Inverter Generator – Generac 6866 IQ2000

If noise levels and portability are your primary criteriaGenerac6866 when looking for a portable generator than inverter generators are the ones you should primarily consider.

Generac 6866 IQ2000 is one such generator, offering all major advantages of inverter technology such as the presence of an alternator which converts output power from DC to AC.

Just like other quality inverters, it is also very quiet. This makes it a preferred choice for camping, RV and tailgating.

You can regulate its OHV engine by choosing from one of the 3 settings to balance the performance and power saving.

Smart LED dashboard is a handy feature allowing you to monitor things like wattage used of fuel levels easily.

While 2000 watts is certainly not a huge amount of power, you can double this by connecting two inverter generators together. (REMEMBER: they should preferably be the same models or at least have the exact same wattage!)

  • Very quiet
  • Modern design
  • Intuitive use
  • Lightweight
  • Just like other inverters it cannot be used to power multiple major devices at a time

6. A Powerful Choice- DuroMax XP10000E 10,000 Watt

At 10000 running watts Duromax Xp10000Eduromax xp 10000 portable generator is the most powerful generator on this list.

It has more than enough wattage to handle multiple large household appliances and high amperage electric tools.

Thanks to a dual fuel technology it can operate both on gas and propane. The choice is yours which one you prefer to use.

Worrying that such powerful portable generator might not necessarily be the most environmental choice? No reasons for concerns at all. Duromax XP10000E is both EPA and CARB compliant meaning that even the residents of California – the state (in)famous for its strict environmental protection laws can use this generator.

An interesting feature of this model is an Idle Control mechanism. It will automatically detect whenever the generator is not used and lower its engine’s RPM (revolutions per minute). This feature alone can mean huge potential savings in the amount of fuel consumed.

If you are looking for a whole house backup power solution, XP10000E is as close as it gets to be a viable alternative for much more expensive and less flexible standby generators. 10000 running watts will give you peace of mind in emergencies and provide enough power for most of the large appliances in your home.

Read more detailed info about Duromax XP10000E here.

  • Very durable and powerful
  • Great alternative to bulky standby generators
  • Idle Control mechanism is a truly awesome feature
  • Easy to clean – an often under-looked feature
  • CARB and EPA compliant
  • It is quite bulky and takes some elbow grease to move
  • As you can probably guess by now – it is not particularly cheap

7. Champion Power Equipment 41135 6800-watt 338CC

Champion Power Equipment 41135 generatorChampion 41135 is indeed a very well designed solid portable generator.

It comes highly recommended for those who are looking for a generator for a jobsite. General contractors and construction workers are going to like this model a lot.

That’s because with its 6800 rated watts it is definitely strong enough to power multiple large work tools such as welders, air compressors, circular saws and so on. At the same time, it still maintains the best feature of portable generators – you can move it from one place to another without major hassle.

While I generally like Westinghouse Wgen7500 more, Champion 41135 makes a good alternative for a slightly lower price tag.

This particularly applies to Californians – this generator is fully CARB compliant.

It has all the useful features you would expect from a good quality generator such as auto low-oil shutdown mechanisms, electronic control and so on.

Generac is one of the most trusted manufacturersGenerac3250 of portable generators on the market. This American company has already established its position as one of the industry leaders.
