Buying Guide

With the new trend of going on vacations with an RV, it is becoming quite important to own a premium quality generator. After all, it’s no fun to be in an RV that doesn’t really have any kind of electricity in it.

But to get a generator, there are quite a few things that you need to know so that you are able to get a value-for-money product. There are true as many bad generators as there are good ones.

If you’ve gone through the list above, you will have realized the many nuances that go into making a generator. There’s the power rating, the number, and voltage of outlets, the fuel tank, fuel type, and other add-ons that make maintenance of a generator easy.

So, to make things a bit clearer, the following will outline some of the main components that you need to be careful about, before buying a generator. It will also guide you regarding what you need to ensure on your part.

Indeed, there’s no point in purchasing such a machine if you don’t know what you want yourself. So, with that in mind, this guide has been prepared for newbies and experts alike, in order for you to take some important pointers related to generators.


Generators are heavy machines with heavy engines that consist of numerous moving parts. This means they are bound to make some level of noise. But it is still not desirable to have a generator that makes a lot of noise.

This is especially true if you want to take the generator for an RV trip. Constantly having to listen to the buzzing of the engine, enjoying a nice, peaceful camping trip can be nothing less than difficult.

However, many heavy-duty generators do not make a lot of noise. You can find out about the noise levels through the decibel rating advertised for the generator.

So, for instance, if a generator has a decibel rating of 59 dBA, its noise levels is just below those of a normal conversation – which stands at 60 dBA.

Heavy-duty generators have a decibel rating of around 76 dBA. So, it’s a bit loud but not as much. And of course, this is probably at 50% of the load. If you operate the generator at full load, then it’s surely going to make a lot of noise.

Engine’s Durability

A generator is no good if you can’t get a good engine. After all, it’s the engine that does the magic behind the scenes. A strong and durable engine can go a long way in ensuring that you get a good return on your investment.

It is however, not practical to assess the quality of an engine manually before purchasing. Most of the times, you wouldn’t even know the many parts that an engine is made of.

A convenient way is to go for well-known brands in the market. Honda’s engine for example, carries a rich lineage and is known for its resilience and incredible power.

Apart from that, you may also get yourself familiar with the types of engines available. When it comes to generators, the primary engine type that is used is the 4-stroke OHV engine.

To understand this, you need to know that a generator’s engine works on the principle of burning fuel and thereby producing energy, which is eventually transformed into electricity.

In short, an engine is made of a cylinder and a piston within. There are some additional parts that are connected to the piston. These parts first begin by causing the piston to move down in the cylinder.

This leaves some space and allows the fuel to flow into the cylinder. The moving parts then cause the piston to move up. This compresses the fuel and builds pressure. The pressure then causes the fuel to burn, which in turn, causes the piston to move down.

The process then keeps on going until you switch off the engine. If you want an engine that can give you a lot of run times and provide a lot of power, then you might want to buy an engine that has a lot of displacement.

Displacement simply tells how far a piston moves down in a cylinder. If it moves down by a lot, then that leaves a lot of space for a considerable amount of fuel to flow in. And this means that a lot of fuel can be burnt when the piston moves.

That is, a higher displacement produces more power since more fuel can be burnt at a time. But then again, this uses up a lot of fuel. Engine displacement is usually advertised in cubic centimeters, or for short.

Then there’s the V-Twin OHV engine. A simple OHV engine has a single cylinder and single piston within. In V-Twin, there are two cylinders joined together in a V-shape. So, this obviously gives more power. But generators with V-Twin are more expensive.

Self-maintaining Features

Generators can be a bit troublesome to maintain. You need to ensure that it’s properly cleaned, the oil is regularly re-filled, there’s not too much load on the generator all the time and the list goes on.

But how would you know when to clean, when to re-fill, and if the generator is overloaded? More complicated still, it’s quite difficult to clean the insides. You never know how much dirt an engine might be accumulating inside.

So, to help you with such troubles, generators usually come with some add-on features. For instance, there can be a low-oil shutdown mechanism, which automatically switches off the generator whenever oil levels are low.

Similarly, an automatic voltage regulator (AVR) on a generator helps in controlling the voltage levels and gives protection from sudden power surges.

Also, you can check to see if the generator you are buying comes with the proper oil and air filters. This makes sure that oil and air are cleaned before they reach the engine. This helps in prolonging the engine’s life.

Such features help you with the generator’s maintenance.

Fuel cost

The purchasing cost is not the only cost associated with a generator. You need fuel to operate it, and as we all know, fuel is one of the most expensive things on planet earth. So, you need to buy a generator that is fuel-efficient.

This means that the generator’s engine should be such that it uses less fuel to produce more energy or power. A few things can ensure this.

For example, getting a generator that has dual-fuel capability might be helpful. Gasoline is expensive, but if the generator can work on LPG and provide ample power, then it would be better to run the generator on LPG since LPG is a bit cheaper.

Also, if the generator comes with inverter technology, then this ensures the generator’s engine reduces its speed whenever there is less load. This means that fuel consumption will be dynamic and adjusted according to the needs.

There are generators with idle-control technology as well. What this does is shut down the generator automatically if the generator detects that there are no running appliances.

Output Wattage

Every generator will have two types of wattage that show how much power you can get from it. There’s the running wattage and then there’s the starting wattage or peak wattage.

Peak wattage shows the power that the generator will provide at start-up. This is the power that causes the connected appliances to power up. The running wattage is the power that the generator provides to keep the appliances running.

Running wattage is always going to be less than starting wattage. Make sure you calculate the power needs of your house or RV so that you know what number of running and starting watts you might be needing.


As you can see, getting a generator is a considerable investment. So, it’s important that you know exactly what you want in order to reduce the risk of making a wrong decision.

You are strongly advised to go through the guide above if you are going to buy a generator for the first time. There are a lot of options out there. Although it’s good to have variety, it, however, makes it a bit difficult to choose.

To ensure that you get the right thing, list down your own requirements as clearly as possible and then check for the things mentioned above as per your needs.

What is remote key fob start?

Some generators come with a facility that allows you to start them remotely. So, you can be at a considerable distance from the generator itself. The key fob has a button that you can then press to power up the generator from afar.

This saves you the trouble of doing a recoil start or actually being near the panel to start up the generator.

What does CARB Compliant mean?

If you are someone who lives in California, then you need to make sure the generator you are getting is CARB compliant.

CARB stands for California Air Resource Board. It has set some emission standards that a generator must fulfill. If it doesn’t, then the generator is deemed to be harming the environment.

Is there any protection from circuit breaks in generators?

Some generators do have built-in features that cut off the power supply to an appliance whenever there’s a circuit fault. For example, GFCI outlets break the circuit to cut off power in order to protect the appliance from any damage.
