Buyer’s Guide

If you don’t know which of the things you have to look at when selecting a 5000-watt generator, then you are at the right place. In this buyer’s guide section, we are going to highlight those things.

Type of Generator

The first thing which you have to do when selecting a 5000-watt generator is to decide which type of generator you want to buy. You can either go for a conventional or an inverter unit.

An inverter generator provides more clean and reliable power to your appliances and electronics. It is fuel-efficient as well makes less noise.

On the other hand, a traditional generator makes more noise, and it is not fuel-efficient, but it is less expensive than an inverter generator.

Single Fuel or Dual Fuel

It is also necessary to determine whether you want a single fuel or a dual fuel generator. It is better to go for a dual fuel generator as it offers you flexibility and freedom of fuel selection. If you have easy access to both fuel options, then a dual fuel generator is the right choice.

LPG is cheaper than gas, so if it is widely available in your area, then it is a good sign for you. Also, propane is more efficient as compared to gas, and you can store propane as much as you can and as long as you can.


Weight of the unit also needs to be considered. If you are going to take your unit outside often, then you should focus on its weight and portability options.

Fuel Tank Capacity and Runtime

Fuel tank capacity also needs to be considered when purchasing a 5000-watt generator. If you are going to run your generator occasionally and for short periods, then a unit with a small tank of 4 gallons is enough for you. But if you are going to use your generator regularly and for more extended periods then more than 6-gallon fuel tank is necessary to buy.

The runtime of a generator differs from unit to unit. Fuel-efficient generators offer more runtime with the same size fuel tank than a non-fuel-efficient unit.  Also, the load changes the runtime. A particular unit will offer different runtime at 25% load and different runtime at 50% and 100% load.

Noise Level

It is also needed to focus on the noise level of your selected product. If you are buying a generator for outdoor activities, then you can forget the noise level. But to use a generator at home with close neighbors, your generator must be noise-free.

Power Outlets

Make sure that the power panel of your generator has the same number and type of power outlets according to the number and type of appliances or electronics you are going to power through your generator.


Your unit must have an automatic voltage regulator. Also, a low-oil shutdown feature is a must. Some units feature a built-in Volt guard to prevent surge power damages. Also, your power outlets must be well covered. Moreover, you must have a spark arrestor in your generator to freely use it outdoors.


A unit with a longer warranty is always suggested to buy. Before giving money to the seller, make sure that your generator is backed by at least a 2-year warranty.
