Cheap Generators – What Are The Best Buys?

A cheap generator does by no means refer to a bad generator. There is a good selection of reasonably priced and low-priced generators available on the market – some of which should, without, doubt, be avoided.

In this post, we’re going to take a look at the 5 best cheap generators that you can buy. In each mini-review, we’ll go through all of the points that are great about the generator, as well as those that could be improved. We’ll provide a non-biased recommendation, as well as suggestions as to which generators are best for which uses.

DuroStar DS4000S – The All Rounder

The Durostar DS4000S is a powerful generator that runs on gasoline. Its maximum wattage is 4000 watts and it runs at a continuous wattage of 3300 watts. We consider the DS4000S to be the best all-rounder cheap generator on our list for a number of reasons. It’s powerful, very well priced, and offers numerous features that are often found on more high-class generators.

As with every generator on the market, there are good things and some points where there is room for improvement. Luckily, in the case of the DS4000S there are a great many points that underpin why its place on our list of the best cheap generators is well-earned.

The DuroStar brand has always been regarded for providing high-quality products, at prices that are considered fair. The DS4000S is designed to be as usable as possible while maintaining high-build quality, with vast reserves of power.

The DS4000S comes fitted with a traditional pull start designed for the easist possible use. Generator users often complain about recoil starters, but the recoil start on this unit is very well reviewed. People comment on how easy it is to start both on cold days and when it hasn’t been used for a period of time.

It’s fitted with all of the safety features that you would expect from a high-quality generator as well. It comes with a system that will automatically detect if the oil level in the engine drops to too low a level. When this happens, the generator will automatically shut down to prevent any major engine damage, which also helps the avoidance of large repair bills.

The control panel is on the front of the generator and has been very ergonomically designed. There is a voltmeter as well as a fuel gauge on this control panel. These are handy features to have as you will be able to see how much power you’re using, and how much fuel you have left. Assuming an eye is kept on the fuel gauge, there won’t be any problems with unexpected losses of power.

The DS4000S from Durostar is a generator that has been designed with rugged use in mind. It isn’t considered particularly lightweight as it weighs in at 94 pounds. However, this is  due to a sturdy steel encasing that enables it to be moved around without concern of breakage. If you would like to make the generator even easier to move around, there is also an optional wheel kit available to buy.

Key Features

  • A maximum power output of 4000 watts, a continuous power output of 3300 watts
  • Portable – the DS4000S can be fitted with a wheel that makes it very portable

The Cons

  • On the heavy side
  • Warranty invalidates if regular recommended maintenance procedures are not applied

The XP4850EH is a unit that’s very capable of handling both small and large loads. However, the sacrifice with a generator that’s this cheap and powerful is the lack of inverter that it has.
