Best Whole-Home
★★★★☆
4.3 out of 5 · 145 ratings
Capacity: 6144Wh, expandable, 7200W output at 120/240V
Fuel: None, no gas, no fumes, no engine noise
Best for: Whole-home backup for anyone who wants power to just come back on
What we like: 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 runs essential circuits for a long stretch.
What we don't: The price is the price. This is a serious purchase 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."
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.
Best Mid-Range
★★★★★
4.6 out of 5 · 597 ratings
Capacity: 3600Wh, 3600W AC output, expandable
Fast charge: Full charge from an outlet in about 2.7 hours
Best for: A middle ground between the Ultra and a small solar generator
What we like: 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 feels like more than you need, this is the sensible step down. It still runs real appliances and still charges fast.
Best Value
★★★★★
4.6 out of 5 · 828 ratings
Capacity: 2042Wh LiFePO4 battery
Charging: USB-C PD 100W fast charging
Best for: Home backup at a more accessible price than the DELTA units
What we like: Over 2000Wh of LiFePO4 capacity at roughly half the price of the EcoFlow DELTA Pro, a strong capacity-to-price ratio.
What we don't: Lower peak output than the EcoFlow units, fine for most household essentials, not for running everything at once.
Jackery's reputation and this unit's capacity make it the pick for anyone who wants real battery backup without spending EcoFlow DELTA Pro money.
Best Budget
★★★★★
4.7 out of 5 · 1,300 ratings
Capacity: 1,024Wh LiFePO4 battery
Charging: Full charge in 49 minutes
Rating: 4.7 stars, the highest of any pick on this page
What we like: The fastest charge time on this page by a wide margin, and the highest star rating too, a genuinely strong budget entry into battery backup.
What we don't: Lower total capacity than the Jackery or EcoFlow units, covers essentials, not a whole home.
For anyone dipping a toe into battery backup without committing to four figures, this is the smartest budget entry point.
Best Solar Bundle
★★★★☆
4.5 out of 5 · 1,300 ratings
Includes: 200W solar panel bundled in
Capacity: 1070Wh LiFePO4 battery
Best for: Off-grid recharging without a wall outlet nearby
What we like: Bundling in a 200W solar panel solves the actual weakness of battery backup, recharging when the grid is down for days, not hours.
What we don't: Solar recharging is weather-dependent and slower than plugging into an outlet.
If an outage might stretch past a day or two, the included solar panel means you're not just running down a battery you can't refill.

Battery Backup vs. Gas Generator
Battery systems 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 for an extended stretch. Gas and dual-fuel generators give more raw power per dollar and can run indefinitely as long as you have fuel.
How Many Watt-Hours Do You Actually Need?
A fridge, some lights, and a WiFi router can run for a day or more on 1,000Wh, which is why budget units like the Anker cover more households than people expect. For running larger appliances or a well pump over multiple days, you're looking at the 3,000Wh-plus range.
Solar Recharging: Worth the Extra Cost?
A solar panel bundle only pays off if your outage might stretch past what your battery alone can cover. For short outages, a wall outlet recharge is faster and doesn't depend on weather. For multi-day off-grid situations, solar is the only way to keep going.
Our Verdict
Most households don't need the DELTA Pro Ultra, as tempting as silent whole-home backup is. The Anker SOLIX C1000 covers real essentials at a genuinely accessible price, and the Jackery Explorer 2000 v2 is the smart step up if you want more capacity without EcoFlow DELTA Pro money. If outages in your area tend to run long, the Jackery solar bundle is worth the extra cost.
