The short answer

Here are the five large power stations people actually buy for extended outages, ranked by what fits your house, not by spec sheet:

Best overall: EcoFlow DELTA Pro, $1,799. The most tested, most bought large station. 3,600Wh, 3,600W.
Best for well water: EcoFlow DELTA Pro 3, $2,799. The only pick here with native 240 volts for a well pump. 4,096Wh, 4,000W.
Best output per dollar: Anker SOLIX F3800, about $1,999. 6,000 watts of output, also 240 volts. 3,840Wh.
Best seller by volume: Jackery Explorer 2000 v2, about $999. Over 2,000 sold in the latest tracked month. 2,042Wh, 2,200W.
Best expandable value: Bluetti AC200L, about $899. Starts at 2,048Wh and grows to 8,192Wh with extra batteries. 2,400W.

Most roundups rank by specs. This one ranks by what buyers actually do, because a station with a thousand reviews and hundreds of monthly sales has been vetted by real outages in a way a spec sheet never is.

How I picked these five

Two rules. First, the unit has to have a real sales history: hundreds of reviews, or hundreds of units a month moving on Amazon. No unproven newcomers, no matter how good the spec sheet looks. Second, it has to run the things that matter in an outage: a sump pump, a fridge, a furnace blower. Every unit here uses lithium iron phosphate (LiFePO4) batteries, which last thousands of cycles instead of hundreds, and every one is indoor-safe and silent, which is the whole point of a battery over a gas generator.

The one famous name missing is the Jackery Explorer 2000 Plus. It sold well, but Jackery is discontinuing it and new standalone units are already hard to find. Its replacement, the 2000 v2 below, is the one to buy now.

Prices are as of November 2026 and move often, especially around sales. Check the live price before you buy.

1. EcoFlow DELTA Pro, $1,799: best overall

The EcoFlow DELTA Pro is the reference point for home backup in 2026. 3,600 watt-hours, 3,600 watts continuous, 7,200 watts of surge, five AC outlets, 1,600 watts of solar input, and a five year warranty. It has 4.5 stars from more than 1,400 Amazon reviews and 400+ bought in the past month, the strongest review base of any large station.

It runs a sump pump, a fridge, a furnace blower, lights, and phones for a day or two on a charge, and longer with solar. It is 99 pounds on wheels, so one person can move it on flat ground. Its one limit is voltage: 120 volts only, so no well pump and no central air. If you are on city water, this is the one to buy. Full write-up in the companion post.

2. EcoFlow DELTA Pro 3, $2,799: best for well water

The EcoFlow DELTA Pro 3 is the newer flagship, and it exists for one reason: native 240-volt output in a single unit. 4,096 watt-hours, 4,000 watts continuous, 2,600 watts of solar input, expandable to 12,000 watt-hours. It was the most-searched whole-home backup unit of 2026 and moved 1,300+ units in the latest tracked month.

If your house runs on well water, this is the only pick on this list that keeps your water running, because a well pump is a 240-volt motor and every 120-volt station on the market physically cannot start it. It costs about $1,000 more than the original DELTA Pro, and for a well home that $1,000 is not optional. Full write-up in the companion post.

3. Anker SOLIX F3800, about $1,999: best output per dollar

The Anker SOLIX F3800 is the muscle of this list. 3,840 watt-hours, but 6,000 watts of continuous output at 120 or 240 volts, with a 9,000-watt surge. That is half again the output of the DELTA Pro 3 for $800 less, which makes it the best watts-per-dollar in whole-home backup. It has 4.4 stars from 161 reviews and 100+ bought in the past month, and it expands to 26,900 watt-hours with extra batteries.

The tradeoffs are weight and newness. At 132 pounds it is the heaviest unit here, and its review base is smaller because it is a newer, more specialized product. One quirk to know: 240-volt output stops while the unit charges from a 120-volt wall outlet. If you want maximum output for the money and you have a well pump or a big load, this is the value pick in the 240-volt class.

4. Jackery Explorer 2000 v2, about $999: best seller by volume

The Jackery Explorer 2000 v2 is the unit the most people actually buy. Over 2,000 sold in the latest tracked month, 4.6 stars from 869 reviews, and 50+ bought in the past month on Amazon. 2,042 watt-hours, 2,200 watts continuous, 4,400 watts surge, and at 39.5 pounds it is by far the lightest unit on this list. One person carries it with one hand.

It is the smallest capacity here, and it is not expandable, so it will not run a house for days. What it does is cover the essentials for a day: fridge, lights, phones, router, and a sump pump in bursts, since its 4,400-watt surge starts a pump motor. It also has a true UPS function that switches in 20 milliseconds, so a computer or a CPAP never sees the outage. If your budget is under $1,000 and you want the most proven unit at that price, this is it.

5. Bluetti AC200L, about $899: best expandable value

The Bluetti AC200L is the buy-now-grow-later pick. 2,048 watt-hours and 2,400 watts on its own, expandable to 8,192 watt-hours with extra batteries, so the inverter and outlets you already paid for keep working as your needs grow. It recharges from a wall outlet to 80 percent in about 45 minutes, the fastest here, and takes up to 1,200 watts of solar. 4.4 stars from 136 reviews.

It is the cheapest way onto this list and the only one that grows fourfold without buying a second unit. Its limits are the same as the Jackery: 120 volts only, so no well pump, and a smaller review base than the EcoFlow units. If you want to start small and add capacity later instead of buying big up front, this is the one.

How to choose in 30 seconds

On well water? You need 240 volts. Pick the DELTA Pro 3 ($2,799) or the Anker F3800 (~$1,999) for more output per dollar.
On city water and want the best all-around unit? DELTA Pro ($1,799).
Budget under $1,000? Jackery 2000 v2 (~$999) for the most proven unit, or Bluetti AC200L (~$899) if you want to expand later.
Want the most power for the money, period? Anker F3800. 6,000 watts for about $2,000 is unmatched on this list.
Want to carry it with one hand? Jackery 2000 v2 at 39.5 pounds. Everything else here is a two-person lift or a wheeled unit.

What they all share, and what none of them do

Every unit here is a lithium iron phosphate battery with an inverter: silent, indoor-safe, no exhaust, no fuel, no maintenance, and instant-on. That is the case for a battery over a gas generator in the first place. A generator runs longer on fuel and costs less per watt, but it cannot run indoors, it is loud, and it needs gasoline from a station that may also be out of power.

And none of these runs a whole house at once. A 3,600 or 4,000 watt-hour battery covers the essentials for a day or two, longer with solar. The discipline is the same on every unit: run the sump pump in bursts, the fridge in cycles, the furnace blower as needed, and the small stuff continuously. The right station is the one that matches your voltage and your budget, not the biggest number on the box.

Bottom line

If you only remember one thing, remember the voltage question. Well water means 240 volts, and that narrows the list to two: the DELTA Pro 3 and the Anker F3800. City water means 120 volts is fine, and the DELTA Pro is the best all-around buy at $1,799. Under $1,000, the Jackery 2000 v2 is the most proven unit money can buy right now, and the Bluetti AC200L is the one that grows with you. All five have real sales behind them, which is more than a spec sheet can tell you.
