The specs, compared
Why these made the list
We built this guide from a pool of 47 inverter generators listed in the catalog. We shortlisted 15 that cover a range of wattage classes, fuel options, and features such as RV readiness, electric start, and CO sensors. We selected only from the given pool, and we did not test any unit. Prices on this page are live, read directly from the store listing at the time shown. All specifications come from the product listings; when a spec is not listed, we say so. We prioritized established brands and avoided near-duplicate models.
Things to weigh before buying
Understand wattage and starting watts
Inverter generators are rated by running watts and peak (starting) watts. The pool uses ranges like “under 3000 W” or “over 9000 W”. For lights and phone charging, a 2000W unit works. For a refrigerator, you need around 2000W running and more at start. For a 30A RV air conditioner, look for at least 3000W. Always check the peak wattage, which is often higher than running wattage, to handle motor starts.
Choose the right fuel type
Gasoline is the most common and easy to store, but it degrades over time. Dual fuel models also run on propane, which stores longer and burns cleaner. Tri fuel adds natural gas, which is ideal for home backup if you have a gas line. Consider your fuel availability and storage before deciding. Propane and natural gas also produce fewer carbon monoxide emissions per unit of fuel, though all generators need proper ventilation.
Look for RV readiness and outlets
If you plan to power an RV, look for a 30A outlet. Many models in this list are marked “RV Ready”. This lets you plug directly into the RV's power cord without an adapter. Some also have 50A outlets for larger RVs or whole-home transfer switches. Check the outlet type on the product listing to match your needs.
Prioritize CO sensors and safety
Carbon monoxide (CO) is a deadly, odorless gas. The CPSC warns never to use a generator inside a home or garage, and to place it at least 20 feet from doors, windows, and vents. Many modern inverters include a CO sensor that automatically shuts off the generator when CO levels rise. The pool includes several models with this feature. If safety is a top concern, choose one with a CO sensor, and always use a battery-operated CO alarm indoors. Sources: CPSC, CDC, EPA.
Consider electric start and remote features
Electric start lets you start the generator with a push button, avoiding the pull cord. Remote start adds convenience, especially for large units that are hard to reach. Some models also offer Bluetooth monitoring for status alerts. These features add weight and cost, so decide if they are worth it for your intended use. For a small camping unit, pull start may be fine; for a heavy home standby, electric start is a must.
Assess weight and portability
Compact inverter generators under 3000W often have wheels or a lightweight frame, making them easy to move. Larger units can weigh over 100 pounds and are best left in a stationary spot. If you plan to take the generator on camping trips or tailgates, prioritize a model under 5000W and with wheels or a handle. For home backup, weight is less of an issue, but still plan a safe, outdoor location.
Questions
What is the difference between an inverter generator and a conventional generator?
An inverter generator roundup focuses on models that produce cleaner, more stable power by electronically converting DC to AC, which is safer for sensitive electronics like laptops and phones. They are typically quieter and more fuel-efficient at partial loads. Conventional generators run at a constant speed and can cause voltage fluctuations, making them less ideal for small devices. All models in this guide are inverter type, as per the pool filter.
How far away should I place a generator from my home?
The CPSC and CDC recommend placing generators at least 20 feet away from any window, door, or vent, with the exhaust pointing away. Never use a generator indoors, in a garage, basement, or shed, even with doors open. Carbon monoxide can build up quickly and kill you in minutes. Always have a working CO alarm inside your home. Sources: CPSC, CDC, EPA.
Can I run an inverter generator in the rain?
No, generators produce electricity and water is a danger. Most are not weatherproof and should only be used in dry conditions. Place the generator on a dry surface under a canopy or cover, but never inside a building. Always keep it away from moisture to prevent electric shock or equipment damage. Follow the manufacturer's instructions on weather protection.
What does dual fuel mean and is it better than single fuel?
Dual fuel means the generator can run on either gasoline or propane. Propane stores indefinitely, while gasoline can degrade in months. Dual fuel offers flexibility: if one fuel runs out, you can switch to the other. It adds a bit of weight and cost, but for many users the convenience is worth it. Tri fuel adds natural gas, which is ideal for home backup if you have a gas line.
How many watts do I need to power a refrigerator?
A standard refrigerator draws about 600-800 running watts and may need 1200-2000 watts at start. A 2000W inverter generator will usually handle it, but you should check the appliance label. For a larger RV with air conditioning, look for a 3000W or higher unit. Always add a margin for starting surges. The pool's wattage ranges help you match the right output.
Are inverter generators safer than conventional ones?
Inverter generators are not inherently safer in terms of carbon monoxide output; all generators produce CO. However, many inverter models now include CO sensors that automatically shut off the generator when dangerous CO levels are detected near the unit. These sensors can add a layer of protection. Always follow outdoor placement rules and install CO alarms in your home, regardless of generator type. Sources: CPSC, EPA.
