Generators are great for domestic, industrial or commercial purposes. They can provide electricity in power cuts, when camping or onsite.
The tank size is the main feature to consider; a larger tank has a longer running time. A fuel indicator level is another useful feature, this enable you to see how much fuel is left so you don’t run out mid use. Some generators produce little noise which is a nice if you intend to use the generator when camping.
Modern generators are often compact and lightweight making them easy to transport and store.
