Shaded rows are our picks. Assumed load: A typical US home averaging 1,200W across the day, about 29 kilowatt-hours, with a 4,000W surge when a large motor starts. Feeding a home panel takes 240V, so only 120/240V models qualify.
One battery is not whole-house backup
A typical US home uses about 1,200W on average across the day. A watt measures how fast power is being used. A watt-hour measures how much is used over time: one watt for one hour. A kilowatt-hour (kWh) is 1,000 of those. At 1,200W, a home uses about 29 kWh a day.
The largest unit here, the EcoFlow Delta Pro 3, holds 4,096Wh. At 1,200W it lasts 2.9 hours. The Anker Solix F3800 holds 3,840Wh and lasts 2.7. A full day would take about 34 kWh out of the battery after losses, more than eight times what the Delta Pro 3 holds.
So one power station can carry a whole house through a short outage, or part of a house through a long one. It cannot do both.
Why only two models qualify
To back up a house, the power station has to feed the breaker panel, the metal box where every circuit in the home starts. A panel takes 240 volts. Voltage is the push behind electricity, like pressure in a water pipe. Wall outlets use 120V, and large appliances use 240V.
Only the Delta Pro 3 and the F3800 list 120/240V output. The other 13 models list 120V only, so the table marks every one of them as unable to do this job.
Peaks matter as much as the average
A house does not draw its 1,200W evenly. When a large motor starts, such as a well pump or a central air conditioner, the draw jumps to about 4,000W for a moment in our numbers. Both picks cover that. Their surge ratings, the most they can supply for an instant, are 8,000W and 9,000W.
Steady heavy loads are the harder problem. An electric clothes dryer or an electric water heater can pull 4,000W or more by itself. That is the whole output of the Delta Pro 3 and two thirds of the F3800’s 6,000W. Ask a station for more than its output and it shuts off. And at a steady 4,000W, the Delta Pro 3 would be empty in under an hour.
On battery power, anything that makes heat with electricity should stay off.
Cut the house down to essentials
This is the change that makes the math work. The power outages guide adds up a fridge, the internet, a few LED lights and phone charging. Together they average 120W, one tenth of the whole-house figure.
At 120W the Delta Pro 3 lasts 29.0 hours and the F3800 lasts 27.2. The batteries are the same. The hours are ten times longer.
A transfer switch can be set up so that only the circuits you choose get backup power. Decide which ones before the outage, not during it. A gas furnace adds about 600W while its blower runs, and the gas furnace guide covers that math.
Expansion batteries and solar
Both makers sell extra batteries that connect to these units. Stored energy and hours rise together, so doubling the watt-hours doubles every runtime here. Check each maker’s page for how many batteries its unit accepts and what the total comes to.
Solar input is the most panel power a station can take in. The Delta Pro 3 accepts up to 2,600W and the F3800 up to 2,400W. Take five hours of strong sun at the full 2,600W as a best case. That is 13,000Wh. It is under half of a 29 kWh day, but enough for more than three days of the 120W essentials list.
The hookup is an electrician’s job
Connecting a power station to a home panel takes a transfer switch. That is a switch that moves circuits from grid power to backup power, so the two can never be connected at once. A licensed electrician has to install it, and the work is part of the real cost of the system. Get the quote before you buy.
Never plug a power station into a wall outlet to feed the house. It can kill.
The picks in detail
Anker Solix F3800
- 2.7 hr
- Whole house, average use
- $1,979.99
- $0.52 per Wh
- 132.3 lb
- Weight
A house panel needs watts as well as hours, and this unit has the most: 6,000W of output and a 9,000W surge rating, more than double the 4,000W burst when a large motor starts. At the 1,200W average it lists 2.7 hours. That is short, so plan on the expansion batteries Anker sells for it and on its 2,400W solar input. At $1,979.99, or $0.52 per watt-hour, it is the cheaper way in.
What fits
- 6,000W output, 2,000W more than the Delta Pro 3
- $0.52 per watt-hour
- Expansion batteries available
What does not
- 2.7 hours at the average home's 1,200W
- 20 ms UPS switchover, against 10 ms on the Delta Pro 3
- 132.3 lb
Anker's list price is $2,199.99. A newer F3800 Plus is sold alongside it for more.
EcoFlow Delta Pro 3
- 2.9 hr
- Whole house, average use
- $2,799
- $0.68 per Wh
- 113.5 lb
- Weight
The Delta Pro 3 lists 2.9 hours at 1,200W, the longest here and still under three. Its 4,000W output and 8,000W surge rating cover the average and the 4,000W motor start, with less room for big appliances than the Anker. Where it leads is refilling. It reaches 80% in 50 minutes from the wall, accepts up to 2,600W of solar, and switches over in 10 ms. Add-on batteries are available. It costs $2,799, or $0.68 per watt-hour.
What fits
- 2.9 hours at 1,200W, the longest here
- Recharges to 80% in 50 minutes
- 2,600W solar input and a 10 ms switchover
What does not
- $819 more than the Anker for 0.2 hours more
- 4,000W output, 2,000W less than the Anker
- 113.5 lb, though it has wheels and a pull handle
EcoFlow's list price is $3,699. It has wheels and a pull handle; at 113.5 lb you will need them.
Verdict
Do not buy either one expecting it to run a whole house for a day. No single unit can. Buy the Anker Solix F3800 if you want the most output for the money as the base of a system you will expand. Choose the EcoFlow Delta Pro 3 if fast refills from the wall or from a large solar array matter more to you than $819. If what you really need is the fridge, internet, lights and phones, a much smaller unit does that job. Whichever you pick, price the electrician and the transfer switch first.
How these numbers were worked out. Runtime = battery capacity × efficiency ÷ average watts. We use 85% efficiency for AC outlets and 90% for DC and USB ports, because some energy is lost as heat on the way out. A model is marked "can't run it" when the device needs more watts than the outlet gives, or a bigger startup surge than the unit is rated for. Your own device may draw more or less than our assumed load, so treat these as estimates. Prices were checked on 2026-10-04 and change often. Full method
