Of these three, Jackery Explorer 2000 v2 is the easiest to move. It weighs 5.3 pounds less than DELTA 3 Max and about 13.5 pounds less than BLUETTI Elite 200 V2. With a measured 1.0 kWh per day, all three reach about 1.7 planning days before recharge. BLUETTI is the choice for extra inverter headroom and EcoFlow for expansion and app control.

How long a refrigerator runs depends on compressor startup, ambient temperature and cycling, and not only on the label wattage.
By the numbers
What we found across the portable power stations we compare, plus the checked facts behind each finding.
Only 2 of the 50 models checked meet every need here: “My priority is keeping food cold”, “It will run beside a bed or desk”, “I need quiet power for my CPAP overnight”, and “I want backup power for the essentials at home”.
2 models fit, out of 50 checkedJackery Explorer 2000 v2 lists 2,042 Wh for battery capacity, 84% above the 1,111 Wh median.
How we countedThe count uses each product's current fit ratings for “My priority is keeping food cold”, “It will run beside a bed or desk”, “I need quiet power for my CPAP overnight”, and “I want backup power for the essentials at home”. A need with no documented match is not counted.
How we calculatedThese are nominal watt-hour ratings. How much energy you get out depends on inverter losses, temperature and load. The median draws on the 50 of 50 models that publish comparable figures.

Decision guide
Run a full-day measurement on the refrigerator and confirm that compressor startup works. If all three can start it, weight and system features matter more than base energy, which is nearly equal.
For a short moment, a compressor pulls more than its steady running load. Before an outage, test your exact refrigerator and any transfer behavior. A surge rating gives useful context but does not prove compatibility.
As room temperature and door openings change, a refrigerator cycles on and off. Measuring watt-hours over 24 hours captures that behavior better than the wattage printed on the appliance label.
Battery capacity is essentially tied with the other two, but this unit moves more easily. That makes it the practical default when the station has to go back and forth between storage and the kitchen.
BLUETTI gives you more output headroom, while EcoFlow supports expansion and deeper control. Go with either one when those capabilities have a named job in the backup plan.
An example with real numbers
Each of the three base batteries is counted at an 85 percent usable-energy allowance in the table.
The mathnominal watt-hours × 0.85 ÷ measured daily watt-hours
| Situation | Jackery | BLUETTI | EcoFlow |
|---|---|---|---|
| 1.0 kWh per day | 1.74 days | 1.76 days | 1.74 days |
| 1.5 kWh per day | 1.16 days | 1.18 days | 1.16 days |
What it tells youOn runtime it is effectively a tie, so weight, output headroom and expansion are better tiebreakers.
Watch out forThese estimates can come up short because of door openings, room heat, inverter idle draw and battery condition.
3 options
Jackery, Explorer 2000 v2
Weighing just 39.5 pounds, this compact 2,042Wh station is built more for quiet refrigerator or overnight backup than for expansion.
Top pick if2kWh appliance backup that’s light and quiet
Capacity can’t be changed, and solar input is modest compared with expandable home-backup systems.
BLUETTI, Elite 200 V2
This densely packed 2,073.6Wh station offers 2,600W output, fast charging and a handy mix of AC, DC and USB ports.
Pick this instead ifIt is the pick when refrigerator startup or another appliance needs the most inverter headroom on this shortlist.
It weighs roughly 53 pounds, which makes it awkward to carry, and it has neither wheels nor an expansion-battery port.
EcoFlow, DELTA 3 Max 2048Wh
This 44.8-pound, 2,048Wh station puts out 2,400W, recharges quickly from AC and is documented as exceptionally quiet under low loads.
Pick this instead ifIt is the pick when expansion, schedules and app control count for more than the added 5.3 pounds.
This page covers the 2,400W DELTA 3 Max. It does not cover the 3,000W Max Plus, and retailer pages at present sometimes lump both variants together.
