Best Portable Generators for Home Backup (2026)

A storm knocks the power out and you find out real fast whether your setup was worth the money. We looked at generators built for actual home backup rather than a weekend at the campsite, from loud-but-proven gas units to battery systems quiet enough to run in the garage without waking the neighborhood.

Best Whole-Home Backup
1. EcoFlow DELTA Pro Ultra 6144Wh Power Station $3,999.00
★★★★☆ 4.3 out of 5 · 145 ratings
EcoFlow DELTA Pro Ultra 6144Wh Power Station
Capacity: 6144Wh, expandable, with 7200W output at 120/240V Fuel: None, it's a battery system, no gas, no fumes, no engine noise Best for: Whole-home backup for anyone who wants power to just come back on
This is the closest thing to a real whole-home standby generator you can get without an electrician and a permit. Silent, no fuel to store, and it can run essential circuits for a long stretch.
What we don't: The price is the price. This is a serious purchase, and it's meant for people who've decided battery backup is worth it over a traditional generator.

"The best generator is the one you don't hear running at 2am during a storm. This is that generator."

We're putting this at the top because for a lot of homeowners, this is genuinely the last generator purchase they'll need to think about. No gas runs, no carbon monoxide risk, no engine maintenance. It costs what it costs, but it's solving the problem completely rather than partially.

Best Gas Backup Generator
2. DuroMax XP13000EH 13,000-Watt Dual Fuel Generator $1,299.00
★★★★★ 4.5 out of 5 · 3,900 ratings
DuroMax XP13000EH 13000 Watt Dual Fuel Portable Generator
Output: 13,000 watts, enough to run a whole home through a transfer switch Fuel: Gas or propane, electric start Rating volume: Nearly 3,900 ratings, the most of any pick on this page
This much output at this price is hard to beat, and dual fuel means you're not stuck if gas is scarce during a real emergency.
What we don't: It's loud and it's heavy. This lives in a garage or shed, not somewhere you can tuck it away easily.

If you want maximum output for the money and you're fine with the noise and the fuel runs, this is the pick. Nearly 3,900 ratings at 4.5 stars is a track record most generators never come close to, and 13,000 watts covers a genuinely large home setup.

Best Quiet Gas Generator
3. Honda EU2200i 2200-Watt Inverter Generator $1,199.00
★★★★★ 4.7 out of 5 · 3,200 ratings
Honda EU2200i 2200 Watt Inverter Generator
Output: 2,200 watts, inverter-clean power safe for electronics Noise: Notably quieter than standard gas generators Best for: Keeping a fridge, WiFi, and essentials running without a huge footprint
Honda's reputation for reliability here isn't marketing, it's earned. Inverter technology means clean power that won't fry sensitive electronics.
What we don't: 2,200 watts is enough for essentials, not a whole house. Know what you're actually powering before you buy.

This isn't the generator that runs your whole home, but it might be the one you actually reach for. It's quiet enough to run near the house, clean enough to charge laptops safely, and reliable enough that Honda owners tend to become Honda owners for life.

Best Mid-Range Battery Backup
4. EcoFlow DELTA Pro 3600Wh Power Station $1,599.00
★★★★★ 4.6 out of 5 · 597 ratings
EcoFlow DELTA Pro 3600Wh Portable Power Station
Capacity: 3600Wh, 3600W AC output, expandable with add-on batteries Fast charge: Full charge from an outlet in about 2.7 hours Best for: A middle ground between the Ultra above and a small solar generator
Real capacity without the Ultra's price tag, and it's expandable if your needs grow later. Fast charging matters more than people expect when a storm is already rolling in.
What we don't: Still a meaningful purchase, this isn't an impulse buy category.

If the Ultra above feels like more than you need, this is the sensible step down. It still runs real appliances, still charges fast, and 597 ratings at 4.6 stars says owners are getting what they paid for.

Best Value Dual-Fuel
5. Westinghouse 7600W Dual Fuel Portable Generator $1,199.99
★★★★☆ 4.3 out of 5 · 2,300 ratings
Westinghouse 7600W Dual Fuel Portable Inverter Generator
Output: 7,600 watts, gas or propane, electric start Rating volume: 2,300 ratings Best for: Solid mid-size backup without the DuroMax's bulk
A genuinely capable generator that covers most household essentials without the price or size of the biggest units on this list.
What we don't: Still a traditional combustion generator, so it needs the same fuel storage and ventilation planning as any gas unit.

This is the practical middle ground for a lot of households, enough output to matter, dual fuel flexibility, and a price that doesn't require the same conversation as the units above it. Good option if you want real backup power without going all in.

Battery Backup vs. Gas Generator

Gas and dual-fuel generators give you more raw power per dollar and can run indefinitely as long as you have fuel. Battery systems like the EcoFlow units are silent, require zero maintenance, and are safe to use indoors or in a garage, but they're limited by their battery capacity once you're off the grid. A lot of households end up choosing based on how long their outages typically last, and how much they value quiet.

How Many Watts Do You Actually Need?

A fridge, some lights, and a WiFi router can run comfortably on 2,000 to 2,500 watts, which is why the Honda EU2200i covers more households than people expect. If you want to run a well pump, central air, or multiple large appliances at once, you're looking at the 7,000 watt-plus range or higher.

Do You Need a Transfer Switch?

If you want a generator to power circuits in your home directly rather than running extension cords to individual devices, you'll want a transfer switch installed by a licensed electrician. It's an added cost, but it's the difference between plugging in a lamp and actually keeping your fridge and furnace running during an outage.

Our Verdict

Most households don't need the DELTA Pro Ultra, as tempting as silent whole-home backup is. The Honda EU2200i covers real essentials for most people without asking for a huge budget, and the DuroMax is the pick if raw output per dollar is what matters most. If you can swing it though, battery backup is genuinely a better long-term experience than another gas can in the garage.
