The only downside to owning it is that it isn’t CARB-compliant. This is a problem especially for those who live in California.
- HouseholdMe
At 94 pounds, the DuroStar DS4000S is relatively heavy to carry or move around without wheels. You may have to acquire a wheel kit at an extra cost. The one year warranty is relatively short when compared to that offered by other manufacturers. With a noise rating of 69 decibels, this generator is considered loud. You have to place it far away from your residence if you are to enjoy some tranquility. This comes at a cost in the form of extra extension cables. Poor packaging. Unnecessary oil spillage when changing the oil due to the lack of a long and angled funnel. The manufacturer doesn’t provide enough tools. You can check the generator’s manual from here. Fuel consumption is high especially in the initial period of using the generator. Lacks a watt or amp meter. Sales representatives are not that reliable. You will require making an oil change every 20 hours. This interval is very small and carrying out oil changes every 20 hours is quite tiring. It’s also not CARB compliant.
- Generator Mag
Only 1 Year Warranty. Noise level a bit too high
- Generator Grid
Needs the optional wheel kit. Not CARB-approved. One-year warranty
- Portable Generator Guide
Will not produce as much power as other generators, but it certainly is effective. It is not carb compliant. No spark arrestor. Requires frequent oil changes.. Not recommended for electronics
- Generator Power Source
Inconvenient oil fill and change. Poor packing. Insufficient tools supplied. Not CARB compliant. Wheel kit not standard.

An Overview On Portable Generators

It’s never a good time for a power outage. Chances are the weather isn’t ideal, leaving you to either swelter or freeze in your house for hours or, worse, days. You can’t even use a fan or space heater to keep your family comfortable. As you watch the battery on your smartphone slowly die, you continue to monitor your local utility company’s online outage report, to no avail.

A generator can keep you up and running, whether an outage lasts an hour or three weeks. Just fill up a gas can at your local station, bring it home and fill up the generator to get started. Depending on the type of generator you buy, filing up one gas can may be enough to last you multiple days, and refilling is easy.

One decision you’ll need to make before you start shopping is whether you want an inverter or a conventional generator. Although inverter generators are more expensive, they’re generally quieter, more efficient and have a longer runtime than their conventional counterparts. If your home suffers only the occasional power outage, it might not be worth the extra price to have those benefits, but you’ll appreciate them if your power ever goes out for days at a time.

How you’ll connect up your generator is also important. You can set up a small generator in a safe area of your house and individually connect the items you use directly to it. Your generator will need to be at least 10 feet from any openings to your house to keep you safe. At that point, you can run one long extension cord from the generator into your home, and then plug multiple items into that. You can alternately run several extension cords into your home for the different appliances you’ll need to use, depending on the power outlets available on your generator.

The other way to use a generator is to hook it up to the transfer switch for your house. This is the safest method since the cord method requires ensuring you have the correct gauge and length of wire. You’ll need a power transfer system, which will have everything necessary to connect a portable generator to a home. The benefit of these systems is that you won’t have to connect individual appliances. You can run the items you need as you normally would, although you’ll still want to conserve energy to avoid multiple trips to the gas station during your outage.

The Portable Generator Buying Guide

  • If your power goes out, chances are you’ll be using your generator for only those things you absolutely need. Still, it’s important to check the capacity.
  • For those who live in colder climates where conditions like ice storms tend to cause extended power outages, a unit with cold start technology helps to ensure you can still run it when the temperature drops.
  • One common issue with generators is a fluctuation in power that can make it difficult to run appliances and electronics. A generator with automatic voltage regulation keeps those fluctuations at bay.
  • When it comes to capacity, wattage is everything. Look for generators with a higher wattage if you’re concerned about keeping your refrigerator going while also intermittently using devices like your stove, toaster and smartphone.
  • If you plan to connect your generator directly to appliances rather than hooking it up to your home’s transfer switch, pay close attention to the electrical outlets included.
  • If you’ve ever heard a generator, you know they can be distractingly noisy. Generators are getting better about this, though. Check the dBA of generators you are considering. The lower the dBA, the quieter the generator will be.
  • In the event of an outage that lasts days, fuel capacity will be more important than any other factor.
  • Before you buy, consider whether portability is an issue. If you plan to leave it in one place most of the time, you probably won’t prioritize that feature.
