Quick Picks

How We Picked

Cold-weather suitability starts with fuel flexibility. Every generator here supports propane, while several also accept natural gas or gasoline. That matters because propane is convenient to store, but gasoline can be easier to source during a prolonged outage and natural gas can offer an ongoing household supply where a compatible connection is available.

We also prioritized electric or remote electric starting, since pulling a recoil cord in freezing weather is less appealing when the generator is needed immediately. Output was another major factor: higher-wattage models are better suited to transfer-switch installation and larger loads, while smaller units make more sense for selected appliances, RV equipment, or a limited emergency setup. Finally, we considered the stated transfer-switch readiness, RV compatibility, inverter design, and price without assigning performance claims that cannot be verified from the listed specifications.

The 8 Best Picks

1. Generac 12,500 Starting Watt Tri-Fuel Portable Generator, Electric Start

The Generac is a strong all-around choice for homeowners who want propane capability without giving up gasoline or natural gas flexibility. Its 12,500 starting watts put it in the serious home-backup category, while electric start is a welcome feature when temperatures drop. Tri-fuel operation also gives you more ways to keep the generator supplied during a long outage. It is a good fit for a transfer-switch setup and households that want one machine to cover several backup scenarios.

• Pro: Tri-fuel flexibility supports propane, gasoline, and natural gas.
• Pro: Electric start is convenient for cold-weather operation.

Skip it if you only need to run a few essentials or want the lowest-cost option.

2. Westinghouse 14500 Peak Watt Dual Fuel Home Backup Portable Generator

For buyers who want the highest listed output in this group, the Westinghouse 14500 is the standout. It is built around home backup, includes remote electric start, and is transfer-switch ready. Dual-fuel operation keeps propane available for storage-friendly backup while preserving gasoline as an alternative. That combination makes sense for a larger home with several circuits to support, particularly when a generator may be positioned outside and started from indoors. Its premium price is easier to justify when maximum capacity matters more than compactness or fuel variety.

• Pro: The 14,500 peak-watt rating offers the most output here.
• Pro: Remote electric start adds convenience during freezing conditions.
• Con: It costs $1349, making it the most expensive pick.

Skip it if your backup plan is limited to a refrigerator, lights, and a few small appliances.

3. DuroStar DS13000MXT 13,000-Watt 500cc Tri Fuel Portable Generator

The DuroStar DS13000MXT is one of the most compelling value choices for whole-home backup. Its 13,000-watt rating, 500cc engine designation, remote electric start, and transfer-switch readiness give it the equipment list many homeowners want for a serious outage plan. Tri-fuel support is especially useful if propane availability becomes limited or a natural-gas connection is part of the installation. At $999, it undercuts the larger Westinghouse while offering more fuel flexibility than several similarly powerful alternatives.

• Pro: Tri-fuel operation provides propane, gasoline, and natural gas options.
• Pro: Remote electric start and transfer-switch readiness suit home backup.
• Con: Its large output may be excessive for small, appliance-only setups.

Skip it if portability for RV trips or occasional light-duty use is your priority.

4. DuroMax XP5500HX 5,500-Watt Dual Fuel Portable Generator

The DuroMax XP5500HX is a practical middle-ground generator for emergency use. Its 5,500-watt rating is more manageable than the high-output home-backup models, while dual-fuel operation lets you choose propane or gasoline. Electric start is valuable when cold weather makes manual starting less appealing, and the RV-ready design broadens its usefulness beyond a home outage. This is a sensible pick for essential appliances, selected circuits, camping, and backup situations where a transfer-switch-ready large generator would be more machine than you need.

• Pro: Dual-fuel capability gives propane and gasoline flexibility.
• Pro: Electric start and RV readiness make it versatile.
• Con: Its output is not aimed at extensive whole-home loads.

Skip it if you need natural gas support or the capacity to run many large loads at once.

6. Champion 4000-Watt Dual Fuel RV Ready Portable Inverter Generator

The Champion is the specialized choice for RV owners and shoppers who prefer an inverter generator. It supports propane and gasoline, offers a 4,000-watt rating, and is explicitly RV ready. The inverter format makes it appealing when portable power and equipment compatibility are central concerns, rather than maximum household capacity. Dual-fuel operation also helps when propane is the preferred cold-weather fuel but gasoline is easier to obtain on a trip. Its price reflects that more specialized design.

• Pro: Inverter design and RV readiness suit mobile power needs.
• Pro: Dual-fuel operation provides propane and gasoline choices.
• Con: The 4,000-watt rating is modest for broad home backup.

Skip it if your main goal is transfer-switch-ready whole-home power.

7. Westinghouse 13500 Peak Watt Dual Fuel Home Backup Portable Generator

This Westinghouse delivers substantial home-backup capacity at a lower price than the brand’s 14500 model. It has a 13,500-watt peak rating, remote electric start, transfer-switch readiness, and dual-fuel operation. For homeowners who want a large propane-capable generator but do not need tri-fuel flexibility, it is an appealing balance. The remote start is particularly useful when the generator is stationed outside during a winter outage, while the home-backup focus keeps the feature set aligned with fixed emergency use.

• Pro: High output supports demanding home-backup plans.
• Pro: Remote start and transfer-switch readiness add convenience.
• Con: It does not offer natural gas operation.

Skip it if you specifically want three fuel choices or need a smaller RV-oriented unit.

The tri-fuel version gives homeowners the same 13,500-watt peak class with an additional natural gas option. It includes remote electric start and is transfer-switch ready, making it a logical choice for a prepared household that wants propane for storage, gasoline for flexibility, and natural gas when available. At $1249, it costs more than the dual-fuel version, so the extra expense makes sense only if that third fuel source is genuinely useful. Cold-weather buyers will appreciate having alternatives if one supply becomes difficult to access.

• Pro: Tri-fuel operation maximizes fuel flexibility.
• Pro: Remote start and transfer-switch readiness suit home backup.
• Con: It costs $150 more than the comparable dual-fuel model.

Skip it if your home has no practical natural-gas option and propane plus gasoline are sufficient.

Buying Guide

Choose output for your actual loads

Start with the appliances and circuits you truly need during an outage. A smaller generator can cover essentials, while a 13,000-watt-class model is better suited to broader home backup. Remember that motors can demand extra starting power, so compare both the generator’s starting or peak rating and the requirements of your appliances.

Decide whether tri-fuel is worth it

Propane is a convenient primary choice for many cold-weather buyers, but gasoline can provide another supply route. Natural gas adds even more flexibility when a suitable household connection exists. If you will only use propane and gasoline, a dual-fuel model may save money; if fuel availability is uncertain, tri-fuel can be worthwhile.

Plan the cold-weather setup

Electric or remote electric start is preferable when the generator may sit in freezing conditions. Keep the unit outdoors in a safe, ventilated location, protect connections from weather, and arrange any transfer-switch installation with a qualified professional. Never operate a fuel-burning generator indoors, in a garage, or near doors and windows.

Our Verdict

The DuroStar DS13000MXT is our best overall pick because it combines high output, tri-fuel flexibility, remote electric start, transfer-switch readiness, and a $999 price. Choose the Generac for a similarly flexible home-backup approach, the Westinghouse 14500 for maximum listed output, or the WEN when budget matters most. RV owners should look first at the Champion, while the DuroMax offers a useful balance of portability and emergency capacity.

FAQ

Is propane good for cold-weather generator starts?

Propane can be a practical cold-weather fuel because it stores well and avoids the long-term storage concerns associated with gasoline. However, starting performance still depends on the generator’s starting system, battery condition, maintenance, and proper outdoor setup.

Should I choose dual-fuel or tri-fuel?

Choose dual-fuel if propane and gasoline meet your needs. Tri-fuel is better when natural gas is available or you want the broadest range of backup fuel options during a prolonged outage.

Do I need a transfer switch?

A transfer switch is the appropriate way to connect a portable generator to selected household circuits. Use a qualified electrician for installation, and confirm that the generator is specifically described as transfer-switch ready.

Can I run a generator inside a garage during a snowstorm?

No. A portable generator should never run inside a home, garage, basement, or other enclosed area. Place it outdoors in a safe, well-ventilated location away from openings, following the manufacturer’s safety instructions.
