Best RV Generator Reviews

When you go camping or boondocking, the best RV generator is a top item on your packing list. Whatever the circumstances, it’ll let you have lights, a working water pump, and an air conditioner. It’ll power up your RV outlets and save your smartphone battery from going flat so that you can call for help once you need it.

The generators for RV vehicles differ greatly depending on the task (heavy / light duty) and other factors. Looking for a power station for your RV, check the following parameters:

  • Wattage. Depending on the number of appliances used in your RV, you might need a more or less powerful generator. The specs of the devices should also be considered. The generator might be enough to power 400W TV and several 100W lamps but be insufficient to start the 3,500W air conditioner (15,000 BTU often used in RVs).
  • Fuel. Gas, gasoline, diesel, or propane — each type of generators can be efficient for a particular task, while the fuel consumption and noise level differ.
  • Run time. Small generators running approximately 4 hours on a single tank, fit the light-duty camping purposes, while the 8-10 -hours generators secure your RV better in case of shore supply fail or any emergency.
  • Noise level. The quieter the better. Generator noise differs from audible buzzing to roaring.
  • Operation. Automatic start is preferable to the manual pulling at the cord, both for safety, efficiency and comfort.

Buyer’s Guide

What Size Generator for RV Should I Pick?

Among both seasoned and beginner RV-ers, the question like “What size generator for 30-Amp RV?” has probably already hit the top questions list. In order to determine the generator size, consider the following factors:

  • Wattage consumption. Draw a table, and include every appliance you’re planning to use during your RV trips. Make two columns, one for running power and another for starting wattage requirements. Remember to list the devices that would need a charge once and then, like a smartphone, flashlight, or wireless speaker. Then, think of the actual situation and what appliances you would use simultaneously. Draw another table, where list the situations and maximum starting and running consumption. This will let you understand your power needs and calculate the generator’s size (remember to add some 100-400 watts to avoid overloading issues). If your maximum wattage doesn’t exceed 600W — you’ll be good with the 800A and more generator. If it falls between 1,000W and 2,000W, consider more powerful models (e.g. for 1,900 running watts and 2,400 starting ones).
  • Noise. The rule of thumb is “more power — more noise”, the dBs ranging from 50 on small generators (lower than 1,000W) to 78 on large models (3,500W and more).
  • Size & weight. The more power the generator produces, the heavier and larger it is. The generators below 1,000W can be 16 x 13 x 14 inches, while the high-capacity 4,000W and more generators are closer to the 39 x 25 x 23 inches dimensions.

The 30 Amp RV will be fine with most of the 1,000W-3,000W generators. If you’re interested in what size generator for 50-Amp RV you‘ll need, it could be the same 3,000W. Still, to satisfy all your RV needs at once, you’ll need the large 5,000W+ models.

How to Start RV Generator

  1. Get through the manual. However boring it might seem, the manual will provide an understanding of the principle of work of the very model you have, and the way to start it. The safety rules and maintenance chapter should also be read before you set to start your generator.
  2. Get prepared. Disconnect all cables and check the level of oil and fuel. In the case of a new generator, the oil should be changed before the first start.
  3. Turn the fuel valve into the “On” position to let the fuel go to the carb.
  4. Close the choke. Turn the relevant dial or lever to the left.
  5. Activate the engine pressing the relevant switch.
  6. Pull at the recoil until you feel the vibration and release it gently. Repeat if necessary. If the engine is still, try to move the choke to the half-open position.
  7. Upon the engine working for a few minutes, set the choke to open / run position.

The modern generators become more automatic and some of RV power stations also provide that option. With a fully automatic start model, all you need to do upon the preparation stage is to press the “Start” button. With half-automatic machines, you might need to operate the choke manually and activate the engine through the electric start button.

How to Charge RV Battery with Generator

There are several ways to charge the battery of your RV with the onboard or stand-alone generator. However, in most cases, this will take more time than with the electricity network, due to the lower amperage of the generator. The usual generator load should also be considered. Before starting to charge the power pack, do the following:

  • Disconnect all other connections if possible. If not, turn off as many hooked up appliances as possible.
  • Fill the generator with fuel or hook it to the shore power source.
  • Maintain the battery. Clean the leads and pour the distilled water if needed (applied to the non-sealed lead-acid power banks only).

Ways to feed your RV battery with the generator:

  • From the DC outlet on the generator. If you have a battery charger, you can plug it into the port and trickle charge the RV battery.
  • From RV outlets. While the generator powers up the RV network, it provides a steady current for the electricity system. Plug a battery charger into the outlet and connect it to the power bank.
  • Through generator leads or plugged-in leads. You can try to power your RV battery via the direct generator leads or using the relevant leads appliance connected to the generator outlet.
