Buying Guide for 4500-watt Inverter RV Generator

You can find various inverter generators at the stores. But not all of them may work with RVs or trailers. So, we are here to help in making your purchase more successful. Keep these below facts in mind before buying a 4500-watt inverter generator:


By size, we refer to the measurement of the fuel tank and the whole unit.

In the fuel tank case, it has a major role in setting the generator’s runtime. There is a possibility of getting longer runtime if your selected machine has a larger fuel tank. But it also has a negative issue as a larger tank adds extra weight to the unit.

Alternatively, camping or RV inverter generators must be compact for better storage and easy movement. You may usually find 10-15” size generators for recreational vehicles. But you can select a larger one depending on your needs. Therefore, we suggest you choose a compact size as it saves space you can use to carry other stuffs.

Power Delivery

If you want an RV inverter generator, pick one that can deliver sufficient power to charge or run different devices and appliances. In this case, a 4500-watt inverter generator is a good one.

You may find specific generators if you want to charge handy devices like smartphones, smartwatches, tablets, or laptops. Even some devices can power the air conditioner of RVs and appliances.

We suggest you avoid powering all the devices at once. It can overload the circuit breaker and invite unexpected situations. Primarily when you use the air conditioner in your RV, try not to power other devices unless the generator is powerful enough like our mentioned ones.

Noise Level

It cannot be delightful if you need to turn off the generator while you are camping. Also, loud noises are harmful to the ears. Generators are technically noisy devices which is a drawback. But the good thing is modern inverter generators produce less noise.

You can check the product description to know the noise levels. Hence, generators producing 60-70 dBA or decibels suit anyone. You can run your regular conversation peacefully even if you stay close to the device.


Many RV owners may ignore this fact – the portability of the inverter generator. But this device should be handy to carry and store. You should not pick one that weighs a lot or has no option to move.

Generally, portable generators have never-flat-type wheels and user-friendly handles. These things help to load and unload the machine in the RVs. Also, you may find some alternatives that are permanently installed on the RV. They are connected to batteries or onboard fuel sources. But they may not offer sufficient features like portable ones.

On average, a standard inverter generator weighs 95-120 pounds. You should pick one that weighs less while keeping other factors in mind.

Number of Outlets

Inverter generators for RV typically have multiple outlets to power your gears. These outlets can be household, automotive-style, USB adapters, etc. Household outlets are suitable to connect and power household equipment. Similarly, a USB adapter outlet is great for charging portable devices like phones or laptops.

Check if your selected model offers these outlets or not. At least, it must have one USB port which is very useful on a trip or camping with RVs.

Frequently Asked Questions

Some common queries found online are here when you look for a quality 4500-watt inverter generator:

Q: Who makes the best 4500-watt generator?

We cannot claim a single manufacturer as the “best maker” of the 4500-watt generator. But compared to most brands, you can find several of them are better than average ones. For example, we have discovered Champion Power Equipment, Pulsar, WEN etc., have great demand in the market. They produce unique generators that last for years. Even they meet CARB compliances for maintaining regulations. Also, they are suitable for the budget, fuel efficiency, features, and performance.

Q: What can a 4500-watt inverter generator run?

A 4500-watt inverter generator means it starts with 4500 watts but runs 3500-3700 watts. This power output can power one AC, a battery charger, a TV, and a WIFI router at minimum. Thus, you may see instructions or a user manual to know which devices you can use with the inverter generator.

Q: What size generator is good for an RV?

Typically, a 30-amp RV with an air conditioner can run with a 2500–2800-watt generator. But it is ideal to use a device that produces more power as many of us do not only want to run the AC only. The more powerful generator you can have, the more machines you can operate without worrying about power output. In this case, generators with 3500+ watts can be a suitable choice for any of the items discussed in this guide.

Q: Is there a generator that is not noisy?

Yes, many inverter generators produce less noise just like our regular conversation. Our guide has mentioned five less noisy products ideal for trailing, tailgating, or camping. Consequently, you should pick a generator that produces nearly 60 decibels (written on the package or manual).

Q: What is best, the inverter or the generator?

Conventional generators can produce comparatively more power and noise than inverters. They require lower initial costs and fewer expenses to have one. But, they are susceptible to sparks and heating issues. Even they cannot provide a long or consistent runtime for power output. Alternatively, inverter or inverter generators have no heating or spark issues. You can get clean and stable power from them.

Final Words

The journey of the best 4500-watt inverter generator for RV ends here. We hope we have resolved the problem of choosing the correct item for your RV.

All these five generators are excellent in their ways. They have high power and consistent output without producing lots of noise. Also, you can carry them anywhere and store them easily.

For best runtime, you can use a Pulsar G450RN inverter generator. If you move a lot with an RV, select Champion Power Equipment 200986 inverter generator. Similarly, WEN GN4500 can be the most affordable choice.
