The EcoFlow DELTA Pro 3 is a whole-home class station with 4,096 Wh of LiFePO4 storage, 4,000 W of output (8,000 W surge, 6,000 W with X-Boost) and both 120V and 240V outlets for large appliances. It charges to 80% in about 50 minutes, takes up to 2,600 W of solar, and can add extra batteries or connect to a transfer switch. At 113.5 lb and a high price, it makes sense for serious home backup rather than camping.

From a full charge, the DELTA Pro 3 runs a full-size fridge for about 77 hours, just over three days. A CPAP with its heated humidifier gets about 12 nights, and a 1/3 HP sump pump running 10% of the time lasts about 44 hours. A 1,500 W space heater cycling on its thermostat drains it in under 5 hours.
One device at a time, from a full charge. Devices that cycle on and off (fridges, freezers, heaters, pumps) use their average draw.
Battery Wh × 0.85 ÷ the device’s average watts. “Can’t run it” means the device needs more than 4,000 W or a start-up surge above 8,000 W. Try your own mix in the calculator.
A full answer for each device on the EcoFlow DELTA Pro 3: hours, start-up surge and other units to consider.
No other single box on this site holds more. At 4,096 Wh it is a little ahead of the Anker SOLIX F3800 Plus (3,840 Wh) and well ahead of the Jackery HomePower 3000 (3,072 Wh). It suits a house that loses power for days at a time and has one or two heavy or 240V loads, such as a well pump, that do not all need to run at once.
Wall charging is where it pulls ahead. It reaches 80% in about 50 minutes, while the F3800 Plus needs an estimated 3 hours and the HomePower 3000 about 2.2 hours to full. If the grid comes back for an hour mid-storm, or you run a generator for a short while, you end up with a mostly full battery. Its 10 ms UPS switch-over is also the quickest of the big units, apart from the two 0 ms outlets on the BLUETTI Apex 300.
Output is the trade-off. At 4,000 W continuous it cannot run as many heavy loads at once as the F3800 Plus’s 6,000 W, and X-Boost only helps simple heating loads, up to 6,000 W. Expansion stops at 12,000 Wh, less than half of the Anker’s 26,880 Wh. It weighs 113.5 lb on wheels, and its DC power comes from Anderson and DC5521 ports, not a car-style socket, so a 12V cooler with a car plug cannot plug straight in.
3,840 Wh · 6,000 W output · 136.7 lb
Pick the F3800 Plus if you need more running at the same time or plan to expand a lot. It puts out 6,000 W, takes 3,200 W of solar, grows to 26,880 Wh and usually costs less. It is 23 lb heavier and much slower to charge from the wall.
3,072 Wh · 3,600 W output · 59.5 lb
Pick the HomePower 3000 if your home runs on 120V loads and you want to spend far less. It holds 3,072 Wh, weighs 59.5 lb and has a car port, but it cannot add batteries and does not list 240V output.

Estimates: battery Wh × 0.85 ÷ the device’s average draw. Real runtime depends on temperature, battery age and how hard the device works.
