The EcoFlow DELTA 3 Plus is the upgraded DELTA 3, with the same 1,024 Wh battery and 1,800 W output plus a second solar input (1,000 W total) and faster 140 W USB-C ports. Its 10 ms UPS switch-over keeps computers and medical gear running through outages, making it a strong all-round pick for a fridge, CPAP or home office during a blackout. The main limit is size: at 27.6 lb it is a two-hand carry.

A CPAP with its heated humidifier runs about 26 hours, three full nights, and a laptop gets about 22 hours of use. Run a full-size fridge and that CPAP together and you get about 11 hours, enough to carry both through one night of an outage.
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 1,800 W or a start-up surge above 3,600 W. Try your own mix in the calculator.
A full answer for each device on the EcoFlow DELTA 3 Plus: hours, start-up surge and other units to consider.
Buy the Plus for solar. It has two solar inputs that take 500 W each, 1,000 W in all, twice what the plain DELTA 3 accepts. A full-size fridge uses about 1,100 Wh a day. With enough panels, a few good hours of sun can put most of that back, which is what makes a multi-day outage or a week in a van workable.
Everything else matches the DELTA 3: 1,024 Wh, 1,800 W of output, 3,600 W surge, a 56-minute wall recharge, six AC outlets, 27.6 lb and expansion to 5,000 Wh. The other upgrades are small. Its two USB-C ports give 140 W each instead of 100 W, which charges a large laptop at full speed, and it has three 12V outlets instead of two. If you will not use either, the DELTA 3 runs the same devices for the same time.
Against the DJI Power 1000 V2, it has less output (1,800 W against 2,600 W) and a lower expansion ceiling (5,000 Wh against 11,264 Wh). It wins on surge, starting a 1/2 HP well pump the DJI cannot, and it has a car socket and solar inputs built in. Its limits are weight, at 27.6 lb, and an output that rules out an 1,875 W hair dryer at full heat.
1,024 Wh · 1,800 W output · 27.6 lb
Pick the DELTA 3 if you charge mostly from the wall. You keep the same battery, output, weight and expansion. You give up half the solar input (500 W), 40 W of USB-C speed and one 12V outlet, and you usually pay less.
1,024 Wh · 2,600 W output · 31.3 lb
Pick the DJI for home backup that may grow large. It has 2,600 W of output, expands to 11,264 Wh (about nine days of fridge power) and usually costs less. It cannot start a well pump, has no car socket and needs a DJI add-on for solar.
