How Do I Choose The Best Gas-Powered Generator?

We all know that natural disasters can happen at any time. You’re only a step away from having to survive without the comforts of your home. Most people don’t like hearing those words, but this is the reality we are talking about and making preparations for it should be one of your current focuses. We’ll start by recommending a generator that can be used during times of need, as well as an alternative power source in case some disaster, will occur and your home won’t have electricity for several days, weeks or even months.

You know you don’t want to lose the food in your freezer or refrigerator. You also want to make sure that you have access to water, both in your bathtub and kitchen sink and most importantly, uninterrupted access to light during nighttime hours. A portable generator offers all those things along with more benefits which we’ll bring up shortly. Continue reading below to learn our list of the Top 3 Best Gas-Powered Generators available on the market today!

Gas-powered generators operate from gasoline or diesel fuel stored on site. They’re attached to the outside of your home by running an extension cord to reach a power outlet. They’re one of the most reliable sources for emergency backup power, and they eliminate the need for costly installation work or long-distance extension cords.

Sizing a Generator Correctly

Before choosing a portable generator, you’ll have to measure the electrical load of your house and determine how much power you need it to supply. After that, you should calculate the wattage provided by your backup generator.

If you are looking for a backup solution for your home (not for emergencies) then you can opt for a smaller generator which costs less money than bigger ones, but their purpose is limited because they don’t deliver enough power to run multiple appliances at once as bigger models do. Also, keep in mind that some states limit the number of hours per week when generators can be operated. These limitations usually apply during winter time, when heating loads – and thus electricity usage increases significantly.

Buying Options

2-cylinder gas models – are often used for construction sites while 4-cycle models – are more common around households. They both have their advantages depending on what you need them for. The most popular portable generators on the market are 2-cycle models. They’re affordable and lightweight so they won’t cost you too much to use them for backup power purposes, or simply for recreational activities. These machines are also easier to maintain because of their 1-piece engine design and as a result, it costs less money out of your pocket in the long run. However, if you want the added benefits of more power and longer running times, 4-cycle models are definitely worth checking out!

Keep an eye on the wattage capacity of the generator

When choosing the best gas generator for your needs, it is important to keep track of the wattage capacity. You’ll want to know how much juice (measured in watts) each unit can produce – especially if you’re planning on using them regularly around your home. Keep in mind that a higher wattage allows units to power more appliances at once and they will work with less strain on their engine. This means that they have a longer working life! As you probably know, the amount of watts an appliance uses determines whether or not it’s suitable for backup purposes – so if you have a lot of devices running around your house, be sure to get something with enough power output! Running Time Many customers consider running time as being one of the most important factors when it comes to choosing a portable gas-powered generator. The more time these machines can keep their engines running, the less you’ll have to worry about your devices draining power out of them while they’re in use! To put this into perspective – Honda’s portables are one of the best choices if you want quality over quantity. Models like the EU1000i and EU2000i only produce 1000 and 2000 watts respectively, but they can run for up to 12 hours on a single tank full! This is why we highly recommend checking out its product line if you’re looking for something with long-lasting capabilities.

Generator Safety

During times of power outages/emergencies, safety has to become one of your priorities – regardless of what you’re doing. Portable gas-powered generators are as safe as they get during this type of situation because they don’t require any installation work before being used. Just fill them with fuel and plug them into a wall socket near where you need power. That said, we recommend reading these 5 tips for using portable gas generators safely and efficiently:

  • Run the machine for short periods of time only – Running your generator constantly will result in it overheating, which can lead to an accident or fire. Try to run it for just a few minutes at a time, depending on how much power you need. For example, if you’re powering up your refrigerator, allow the machine to run for no longer than 10-15 minutes before turning it off to let it cool down for 30 minutes or so. You can then turn the generator back on and do this two more times throughout the day. This way you’ll give your backup power source enough rest time between uses in order to prevent running into any serious problems later on!
  • Don’t connect the generator to your house’s electrical system – This is one of the most common mistakes people make when running a generator. The last thing you want to do is hooking it up to your home’s main source of electricity! Doing so can result in electrocution or starting an electrical fire, which will cause a lot more damage than a power outage ever could. If you’re using portable gas generators for emergency backup purposes, look for models that come with inverter technology. These machines are specifically designed for load sharing applications and they transform direct current (DC) electricity into alternating current (AC), which they then distribute via household outlets just like regular utility wires would. If you need extra stability while using this type of equipment, attach surge protectors in-between the generator and your devices to help regulate voltage levels.
  • Check that all gas/vent/water connections are firmly in place – These types of accidents can occur as a result of negligent handling, which is why it’s important to pay attention when connecting and disconnecting these components. Not only will you want to make sure they’re properly secured, but you’ll also want to make sure they’re not leaking fuel or water at any point (which would cause a fire).
  • Use proper safety equipment while running your generator – Regardless of how many years of experience you have with operating generators, we highly suggest wearing protective gear like dust masks when using them. This type of mask will protect your lungs from dust particles triggered by the machine’s constant running and it will ensure your health is not jeopardized in the event of an accident.
  • Don’t use a generator indoors – This is another thing you should never do while using portable gas-powered generators. Your best bet is to find an open space that has at least 3 feet (1 meter) of clear air around it for proper ventilation purposes. Be sure to check out our guide on how to choose a safe location for your unit if you’re not sure where you can place it outdoors!

Running Time

Portable gas generators generally range from about 500 to 7,000 Watts and can run for 4 or more hours on a full tank of gas. That’s the average running time you can expect from the Honda portable generator set shown above – 6,200 watts/8.2 amps @ 120VAC with a peak surge of 10,000 watts/16.5 amps @ 120VAC.

Running times are affected by several factors including: Load type (inductive loads like refrigerators should not be used), climate conditions and fuel quality (low octane gasoline or diesel fuel will reduce your engine’s performance).

Control Panel Features

Generators usually come with a power control panel where you can set up the timing for automatic start and shut down, run time types (continuous or ignition controlled) and wattage output. Most models on the market also have an electric coil to automatically restart your generator after utility power is restored. These features are all included in your best gas-powered generators review below!

The control panel is the main user interface of your generator. It’s where you should find several useful indicators that will tell you how to run the machine safely and efficiently.

Amp/hour meter – displays how long you can operate each load, including electrical (lightning) loads, heating loads, etc. kWh meter – measures total energy use in kilowatt hours over a period of time you pre-select from the settings on the generator

Frequently Asked Questions

How Much Power Do I Need?

Picking the ‘right’ generator will always be a bit of trial-and-error. You need to know how many watts are needed for your home and then go from there, using the best gas-powered portable generator in that watt range. The small differences in two factors such as wattage or gallons per hour (gph) can make quite a difference when it comes to necessary runtime or overall output capacity for any given emergency situation. If you’re looking for something with long-lasting durability and power capacity, we would strongly recommend checking out Honda’s line of products as they have a proven track record of quality in this department.

What is the difference between starting and running watts?

The big distinction between the two is that initial power requirements are usually related to a home’s heating, ventilation, and air conditioning (HVAC) system. Running capacity requirements are more or less directly tied to appliances such as refrigerators, freezers, washing machines, dishwashers, etc. Both of these capacities have to be met during a power outage emergency situation; however, you can determine which one takes priority based on your personal needs and circumstances. For example: if an HVAC system fails during cold weather it will do so nearly instantly while appliances will simply fail after drawing too much power. So, if you have a 20,000-watt generator but it only has 10,000 in starting power – that’s not going to be the best option for you.

How to connect a generator to a house without a transfer switch?

There are two ways to get the power from your generator inside: a temporary hookup and a permanent hookup.

Temporary Hookup

First, you’ll need to find an outlet outside (one that is not attached to your house’s NEMA box) – one that is plugged into either a GFCI or double pole breaker. Then, unplug the device that was previously plugged into it and plug in the cord of your generator. This way if there’s any kind of fault within the wiring between your house and the outside outlet, only the extension cord will be affected!

Permanent Hookup

If you want to make your generator permanently hooked up then you’ll have to hire an electrician who can provide a permanent transfer switch. He can connect your generator to the power lines that feed your house and make sure they’re properly grounded.

Can I plug my generator into an existing outlet?

Yes. You can plug into any grounded 120-volt outlet (up to 15 amps). If there is no pre-existing GFCI receptacle, install one with either a 30 amp or 50 amp breaker depending on your location and needs. A receptacle wired with a smaller wire gauge than 14 AWG may overheat and trip the circuit breaker or blow a fuse when used with a generator.

Does Your Generator Need to Be Grounded?

Most generators come with a three-prong plug, but they can still be dangerous. If you’re using the generator outdoors, then it needs to be grounded to protect both you and your home. It does this by creating an alternative path for electricity in the case of a short circuit. You should have an electrician check the generator before using it, especially if you’ll be running a large appliance off of it.

How far should a generator be from the house?

Generators need some space around them in order to operate effectively, especially if you’re using it during the winter months for heating purposes! *Basically any time you have a gas-powered device with an engine inside, there’s going to be exhaust fumes hence it needs some distance so as not to breathe in those.*  Usually 8 feet is sufficient with 4 feet being ideal.

If you live in an area where it snows, then that’s usually another good indication to not place your generator too close to the house. Otherwise, if your generator is placed next to a siding or wall then it will also heat up quite a bit more than normal since its exhaust fumes will have nowhere else to go but back through itself! This can cause some serious risk of a fire or explosion so make sure there’s enough distance so as not to damage the paint on your house!

Is It Safe To Run A Generator?

Generators are relatively safe when used correctly and according to direction; however, there are still certain dangers associated with them if they’re operated improperly. For instance: having loose extension cords running across driveways, worn-out spark plugs, or even just using it in an enclosed space without proper ventilation. 


The most important thing you can do is take some time to plan exactly what your generator will be used for before purchasing one. Make sure you don’t overdo it! Too much power can damage certain appliances or worse yet, the wiring in your house. So take some time and make sure everything is thoroughly thought out before investing a lot of money into this big purchase.
