Are you in the market for a 30A generator to power your RV or home? If so, you have to choose one that will provide you with enough power and is both efficient and economical to use. A good generator must be able to power several home electrical appliances simultaneously without showing any sign of getting overloaded.
Factors to Consider When Buying a 30 Amp Generator
Contents
When you’re looking for a generator to buy, your choice will be informed by what you want to use the generator for.
Do you give much weight to portability or power output? Are you interested in fuel economy, and you are looking for aesthetics? These are some of the questions that will help you pick a generator that suits your taste. Here are the factors to consider when you want to buy a generator.
-
Generator power output
This is an important factor when it comes to choosing generators. If anything, we buy generators to supply us with power. You’ll choose a generator depending on the number of appliances you have at home and their power requirements.
A good generator should be able to run all the appliances you have at home, even if you have to run them simultaneously. The power output of a generator will determine its operating costs. So there’s no need to buy a 5000-watt generator when a 3000-watt generator can serve your needs.
-
Parallel connections
You may be in a situation in which one 3000-watt generator suffices to supply all your power needs. What about if you buy new appliances that require additional power? If your appliances need more power than what one generator can provide, it would be better to connect a second generator to the first one for additional power.
However, this can only be possible if your first generator allows a parallel connection. So when buying your first generator, check whether it allows parallel connection so you wouldn’t have any power issues if your power needs increase.
-
Noise Level
Generators are rated differently on matters of the noise level. So this is a factor you need to consider when buying a generator. Noise is disruptive and may not allow you to enjoy a quiet time at home. Furthermore, it may also cause friction between you and your neighbors.
Different jurisdictions also have laws that govern acceptable noise levels. All these issues make noise an important factor in choosing generators. It’s all about your comfort, that of your neighbors, and abiding by the law.
Powerful generators tend to produce more noise than less powerful generators, so you have to balance your power requirements and noise level. Also, generators produce more noise when operating at 100% of their load capacity. Keeping the load low will ensure your generator doesn’t produce much noise. All in all, check the noise level rating of a generator before you buy it.
-
Fuel Type
Most generators run on diesel, propane, or gas. If your RV uses diesel, it would help if your generator uses the same fuel. Again. If your RV runs on gas, buy a generator that runs on gas.
Inverter generators are more fuel-efficient and, therefore, more economical to use than standard generators. The advantage of propane is that it has an indefinite shelf life. This makes it the best fuel to stock to take care of unexpected power outages.
Propane also produces clean energy, making it an environmentally-friendly fuel. However, this fuel may be hard to find in some regions.
The good news is that we have dual-fuel generators, meaning they can be powered by two different fuels.
Buying a dual-fuel generator is the best way to ensure you always have a backup in case you run out of one type of fuel, or if one type of fuel becomes scarce. Even though the dual-generators are economical to use, they tend to be more expensive than ordinary generators.
-
Portability
Most people buy generators to use away from home. That’s why portability is an important factor in choosing a generator. Even if you are using your generator at home, you may want to move it from one place to another from time to time. So you have to consider how portable the generator you are buying is.
Most 30A are heavy, but some have handles and wheels that can be used to move them. So when buying a generator, check its weight and also find out if it has wheels or handles that you can use to move.
-
Performance
When shopping for a generator, you have to consider how best it will serve you. Is it easy to start and operate? How much fuel does it consume, and how much power do you get per gallon? A good generator should have a longer runtime per gallon of fuel. You also have to consider other factors such as ease of use and whether it will need regular maintenance.
-
Cost
Generators come at different price points. High-end generators are more expensive, but they perform better than cheap generators. In buying a generator, you’ll actually get what you pay for. If you want a good generator that lasts longer, you must be prepared to dig deeper into your pockets.

The Honda EU3000iS is a user-friendly generator that packs many useful features. It is known to be power-packed and fuel-efficient. This generator performs better than many generators at its price range.
Design
The Honda EU3000iS generator weighs 131 and measures 17.6×25.9x 22.0 inches. It is the heaviest and the biggest of the 3000-watt Honda models. However, it has two handles on both sides to help in carrying it. In fact, most users don’t mind its weight because it is overshadowed by the power it provides.
The two handles aren’t the only features contributing to its portability. It also has a wheel kit (purchased separately) that you can use to roll it around. The kit is quite easy to install, whether you use the 2-wheel set or the 4-wheel set.
Performance
On matters of power generation, this generator beats many generators in its class. Its 196cc engine produces a running power of 2800 watts and a peak power of 3000 watts. When you fill its tank to capacity, you’ll get about 20 hours of the power supply when it’s running at 25% of its capacity. When running at full load, you’ll get about 7.1 hours runtime.
The greatest advantage of this generator is that it can give you extra surge power to start loads that are difficult to start with many 3000-watt generators. This is perhaps the strongest selling point of this unit. Some of the heavy loads that this generator can start and run include air conditioners, circular saws, sump pumps, and water pumps.
Additionally, you can power these heavy loads alongside other electrical appliances that do not require much power. All in all, this unit will provide enough power for any type of tailgating or RV you use.
Noise level
Noise level is one of the factors considered when buying a generator. Luckily, this source of power is good in terms of the noise level. With all its power, its noise level when running at 25% of its load is 49dBA. At full load, the noise level is only 58dBA. This makes it to be the quietest generator among the 3000-watt Honda generators.
Fuel efficiency
This generator has a capacity of 3.4 gallons. From the manufacturers, when it is full of gas, it should give a runtime of 21 hours at 25% load. However, many reviews from the users of this generator show that it can perform better than that.
Some users claim it offers 15% better performance than what is officially advertised, especially when using ethanol-free gasoline. The reason behind this is that non-ethanol gasoline produces more energy per gallon of fuel.
This machine features an Eco-Throttle that you can turn on to increase fuel efficiency. This system automatically adjusts the generator, so it only produces the power needed for the load plugged in.
Ease of use
Honda’s EU3000iS is quite easy to use. This is because it uses an electric starter and also has a recoil switch. The electric starter can be used when the engine is in START position. And once you start the engine, you can switch it to the ON position.
What we liked
- Provides a reliable performance even with big loads
- Up to 21 hours runtime
- Ideal for the job site and for RV (off-grid) living
What we didn’t like
- It’s expensive
- Oil funnel and wheel kit bought separately.
