Shaded rows are our picks. Assumed load: A full-size fridge averaging 60W, a router and modem at 20W, LED lights at 30W, and phone charging at 10W: 120W on average, with the fridge's 1,200W startup surge.
Start with a list, not a product
Write down what must stay on, then add up the watts. Our list is a full-size fridge averaging 60W, a router and modem at 20W, a few LED lights at 30W, and phone charging at 10W. That comes to 120W on average.
A watt measures how fast power is being used. A watt-hour measures how much is used over time: one watt for one hour. So 120W for a full day is 2,880 watt-hours.
The table shows what that means. A 1,000Wh unit covers about 7.3 hours. A 2,000Wh unit covers about 14.5. The EcoFlow Delta Pro 3, the largest here, covers 29.0.
Your list will differ. Add a CPAP machine at 40W and the total is 160W, so every runtime drops by a quarter. The 14.5 hours becomes about 10.9.
The fridge sets the minimum size
The fridge averages only 60W because its compressor, the pump that does the cooling, pulls about 150W and runs about 40% of the time. Starting that compressor is another matter. It takes about 1,200W for an instant, which is called startup surge.
The three 300W units have 600W surge ratings, so they cannot start a fridge. The EcoFlow River 3 Plus is exactly at its 1,200W surge limit and lists only 2.0 hours. From the Bluetti AC70 up, every unit starts the fridge.
Stretching the hours
The fridge is half the list. A fridge that stays shut holds its cold for a few hours without power, so you can rest it for stretches with the door closed. While it rests, the load is 60W and the battery drains half as fast. A thermometer inside tells you when to plug it back in. Food should stay at 40 degrees F or below.
Overnight, switch off the lights. If nobody is online, switch off the router too.
Multi-day outages need expansion or solar
Two specs matter once an outage passes a day.
The first is expansion. The Anker C2000 Gen 2 grows to 4,096Wh and the EcoFlow Delta 3 Plus to 5kWh. The Delta Pro 3 and the Anker Solix F3800 also take add-on batteries.
The second is solar input, the most panel power a station can accept. A day of the essentials takes about 3,400Wh out of the battery after losses. A unit that accepts 800W to 1,000W can take in that much in about four hours of strong sun, if you own enough panels. A 400W input would need more than eight hours of full output, which a winter day does not give.
What not to plug in
Leave off anything that makes heat. A 1,500W space heater empties a 1,000Wh unit in about 36 minutes, as the space heater guide shows. Electric stoves and clothes dryers need even more power and are not jobs for a battery.
Connecting to the house
Any unit works with extension cords run to the fridge and the router. To feed house circuits directly, you need a 120/240V unit, which means the Delta Pro 3 or the Anker F3800, and an electrician to install a transfer switch. That is a switch that moves chosen circuits from grid power to backup power so the two never connect.
Never plug a power station into a wall outlet to feed the house. It can kill.
The picks in detail
Anker Solix C2000 Gen 2
- 14.5 hr
- Outage essentials (fridge, internet, lights, phones)
- $899.99
- $0.44 per Wh
- 41.7 lb
- Weight
It lists 14.5 hours on the 120W essentials list, enough to run from dinner through the next morning. Its 4,000W surge rating is more than three times the fridge's 1,200W start. For longer outages, one expansion battery takes it to 4,096Wh, and it accepts up to 800W of solar. Anker lists a 9W idle draw, which is low for this size and matters when the load is only 120W.
What fits
- 14.5 hours on the essentials list
- Expandable to 4,096Wh, with 800W solar input
- 10 ms UPS switchover
What does not
- 14.5 hours will not cover a second night without solar or expansion
- 41.7 lb
Anker's list price is $1,499.99. Anker lists a 9W idle draw, which is low for this size.
Bluetti Elite 100 V2
- 7.3 hr
- Outage essentials (fridge, internet, lights, phones)
- $489
- $0.48 per Wh
- 25 lb
- Weight
At $489 this is the lowest-priced 1,000Wh unit, and it covers an evening: 7.3 hours on the essentials list. It accepts 1,000W of solar, which only the EcoFlow Delta 3 Plus matches in its class, at $180 more. In a multi-day outage that lets a large set of panels refill it far faster than the 400W Jackery can accept. Its 3,600W surge rating is three times the fridge's 1,200W start.
What fits
- 7.3 hours for $489
- 1,000W solar input
- 10 ms UPS switchover
What does not
- 7.3 hours will not cover a full night
- Cannot be expanded with extra batteries
Sale prices under $400 have appeared.
EcoFlow Delta 3 Plus
- 7.3 hr
- Outage essentials (fridge, internet, lights, phones)
- $669
- $0.65 per Wh
- 27.6 lb
- Weight
This suits someone who wants to spend less now and add capacity after seeing how the first outage goes. It starts at 1,024Wh and 7.3 hours, and add-on batteries take it up to 5kWh. It has a 1,000W solar input and a UPS mode that takes over from the wall in 10 ms, so the router and modem can stay plugged into it all year. The catch is price. $669 is $0.65 per watt-hour, well above the other 1,000Wh units.
What fits
- Expandable up to 5kWh with add-on batteries
- 10 ms UPS switchover
- 1,000W solar input
What does not
- $0.65 per watt-hour
- 27.6 lb, the heaviest 1,000Wh unit
EcoFlow's list price is $799.
EcoFlow Delta Pro 3
- 29.0 hr
- Outage essentials (fridge, internet, lights, phones)
- $2,799
- $0.68 per Wh
- 113.5 lb
- Weight
This is one of two units here with 120/240V output, the kind an electrician can connect to your home's breaker panel. It lists 29.0 hours on the essentials list, takes add-on batteries and up to 2,600W of solar, and has a 10 ms UPS switchover. The Anker Solix F3800 is the other 120/240V unit. It costs about $820 less and lists 27.2 hours, with a 20 ms switchover and no wall charge time listed.
What fits
- 29.0 hours on the essentials list
- 120/240V output for a transfer switch
- Recharges to 80% in 50 minutes when power returns
What does not
- $2,799, or $0.68 per watt-hour
- 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
Buy the Anker Solix C2000 Gen 2 if you want one unit that carries the fridge, internet, lights and phones overnight, with the option to double it later. Buy the Bluetti Elite 100 V2 if your outages are short and $489 is the budget. Choose the EcoFlow Delta 3 Plus if you want to start at 1,000Wh and add batteries. Go to the EcoFlow Delta Pro 3 or Anker Solix F3800 only if you want backup power tied into the panel. Skip the 300W units, because they cannot start a fridge.
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
