The Best Emergency Backup Generators, Gas Generators, and Portable Generator Systems for Every Situation

Best Emegency Generators

Emergency backup generators and portable generator systems are a godsend during any situation in which your access to power becomes suddenly and unexpectedly compromised, providing access to contingency electricity for light, heat, cooking, and running essential appliances or devices.

There are almost countless emergency situations in which you may find yourself cut off from the power grid and in every one, a reliable portable emergency generator can make the difference between keeping the lights on or having to make do without electricity.

The best outdoor generators and emergency backup generator systems mean that if you find yourself without power, you’ll be able to bring things back online with minimal effort.

In an age of instant energy on switch, it can be all too easy to forget that our access to readily available power is actually the exception rather than the rule and that this luxury is a mere natural disaster or unexpected emergency situation away from disappearing.

If you’ve ever found yourself without electricity, due to an extreme weather event or a major power outage, you’re probably all too aware of just how difficult things can quickly get if the situation becomes prolonged and you’ve not got a backup system in place.

In these instances, having a backup power plan in place forms a core component as the foundation of any survival strategy.

Once physical safety, adequate shelter, clean drinking water, and access to sufficient nutrition are covered, ensuring a connection to a reliable power source when needed is almost certainly the critical thing to make sure you have in place if you find yourself in a situation suddenly unplugged from the grid.

Gas Powered Generators VS Solar Generators

Before we get into breaking down the best emergency backup generators for the money, it’s a good idea to briefly talk about the main differences between the two kinds of emergency generator on the market – those powered by some form of gas or similar fuel and solar powered generators that derive their energy from the sun.

While the main difference between these two kinds of generators seems obvious, it’s the specific (and significant) pros and cons of each which need to be looked at in detail when deciding on the best generator for your needs.

When we talk about a solar generator system, what we’re really describing is a combination of photovoltaic (solar) panels connected to a long-lasting, high capacity battery unit which is used to store the captured solar energy and which you can draw upon for power when needed.

The obvious advantages over this kind of generator system are that firstly, solar energy is free and unlike conventional gas fuels, doesn’t need to be stored, and secondly, no moving parts means that operating this kind of generator setup is silent.

The swing side of these benefits are equally obvious however, and by far the biggest drawback of solar generator systems is that – you guessed it – they’re totally dependent on the sun shining. While you’re going to get some energy captured on overcast days, the return is going to be significantly lower than on a bright sunny day.

Of course the main idea of this kind of system is that you will collect and store the energy when times are good (and when the sun is shining) and can then call on your fully charged batteries when times are not so good, however for many people, this may not be an acceptable solution as a power redundancy for an unexpected emergency that could strike at any moment.

Gas powered emergency generators on the other hand (which we’ll be covering in this guide are not dependent on favorable weather conditions to begin generating power meaning so long as you’ve got an adequate supply of fuel stocked up, you can be up and running again immediately. Batteries can still be charged from the generator if required, but this is an optional extra with this kind of generator.

The major drawbacks of emergency gas powered generators come in the form of operating conditions (gas generators can be both noisy and almost always have to be operated outside or in an area with adequate ventilation) and the fact that they require a stored supply of fuel to ensure continued operation.

Ultimately, there are good and bad points to both kinds of emergency generator systems and the decision of which type is best for you will really depend on your individual preferences, requirements, and circumstances.

The Best Emergency Backup Generators for Every Eventuality

In this guide, we’ve taken a look at the very best gas-powered emergency generators for getting your power supply back online with minimal downtime.

If disaster strikes and the lights go out, these high performance power generators are durable workhorses designed to keep you up and running no matter the emergency.

The Best Dual Fuel Generators

As you’d probably expect from the name, the major benefit of dual fuel generators over their single fuel siblings is the ability to effortlessly switch between either petroleum or propane as the main source of fuel.

There are a couple of major advantages to this kind of generator system and these go beyond the obvious benefit of the increased flexibility of choice.

Generally speaking, gasoline (petroleum) is considered easier to get hold of for use during an emergency and there are often economic benefits of this fuel source over a propane alternative.

On the other side of the coin, propane often represents a ‘cleaner’ fuel which is less likely to cause your generator the kinds of longer-term maintenance issues that are associated with gasoline and is also more shelf stable than gasoline, making it a solid choice for storing over long periods without deterioration.

In this section of the guide, we’ve taken a look at the best dual fuel backup generators for use at home or on the road during an emergency situation.

DuroMax XP4400E 4,400 Watt Gas Powered Portable Generator

This emergency generator is as versatile as it is durable and utilizes a dual fuel system meaning it can operate on either standard gasoline or alternatively, on liquid propane (which burns cleaner and can significantly increase run time).

Other than the operating efficiency, there are a few other benefits to being able to run on this kind of fuel such as the ability to store it for years at a time (gasoline begins to deteriorate over time) and the clean-running characteristics of propane mean it’s not going to accumulate or build-up within the carburetor of the generator in the same way that gasoline would.

Beyond this, the build quality and ease of use of the Duromax XP4400EH means that this is a solid backup generator choice if you’re looking for an emergency power redundancy that delivers a Max AC output of 4400 watts and the ability to run for between 8 and 20 hours depending on fuel type.


In terms of performance and feature set, the Duromax XP4400EH portable generator packs a lot of features (and power) into it’s small frame.

As mentioned earlier, the 7 HP unit utilizes both propane and gasoline for maximum adaptability to help meet your needs and you can expect a rated AC output of 3500 watts with the Max output stretching to 4400.

Construction and build quality are always important practical consideration when it comes to a portable backup generator that’s likely to see action in less than favorable conditions and in this case, the XP4400EH with it’s heavy-duty steel frame, four gallon fuel tank capacity, and air cooling.

Coming in at around 132 lbs when empty, the XP4400EH is just about manageable enough to move where you need it most by hand and is perfectly suited either as a home emergency backup generator or as a portable generator for packing as part of a vehicle load-out if you find yourself needing to evacuate quickly by road. Expect to factor in around another 24 lbs for gasoline to this equation, but the inclusion of all-terrain, never-flat tires and handles effectively negates this when you need to move the unit around.

Technical Specifications:

Run time:20 Hours Propane, 8 Hours Gasoline
Noise Level:69 Db
Output:Max AC output 4400 watt, rated AC output 3500 watt
Generator Unit Dimensions:23.8 x 18 x 20 inches
Generator Unit Weight:Empty: 132 lbs, With Gasoline: 156 lbs
