Best overall
EcoFlow DELTA 3 Plus
Why it ranks here
The most complete refrigerator-backup package in the 1kWh set, especially when solar recharge or later expansion is part of the plan.
- Direct price
- $669
- Rated capacity
- 1,024 Wh
- Continuous AC
- 1,800 W
- Published peak
- 3,600 W
- Solar input
- 1,000 W
- Weight
- 27.6 lb
Value context: Mid-pack direct price in this 1kWh group. The value case is strongest when its 1,000W solar input or expansion path will actually be used.
- Best for
- A flexible home-outage setup that may grow beyond one refrigerator.
- Skip it if
- You want the lowest weight or do not expect to use its higher solar input and expansion options.
What works
- 1,000W maximum solar input
- Published 3,600W surge rating
- Expansion path beyond the built-in 1,024Wh
Tradeoffs
- Heaviest model in the 1kWh comparison
- Costs more than the lowest captured direct-price options
Best lightweight pick
Jackery Explorer 1000 v2
Why it ranks here
The easiest station in this group to move between storage, the kitchen, and a vehicle while retaining a published 3,000W peak.
- Direct price
- $549
- Rated capacity
- 1,070 Wh
- Continuous AC
- 1,500 W
- Published peak
- 3,000 W
- Solar input
- 400 W
- Weight
- 23.8 lb
Value context: One of the lower captured direct prices in the 1kWh set. Its strongest value argument is the 23.8 lb carrying weight, not solar throughput.
- Best for
- Buyers who expect to carry the station often and have modest solar requirements.
- Skip it if
- A 400W solar ceiling would materially slow your recharge plan.
What works
- Lightest at 23.8 lb
- Slightly larger 1,070Wh rated capacity
- Published 3,000W surge peak
Tradeoffs
- Lowest solar input in the group
- Lower continuous output than EcoFlow, BLUETTI, and Anker
Best solar value
BLUETTI Elite 100 V2
Why it ranks here
The strongest captured combination of direct price, 1,000W solar input, and roughly 25 lb portability.
- Direct price
- $499
- Rated capacity
- 1,024 Wh
- Continuous AC
- 1,800 W
- Published peak
- Not separately published
- Solar input
- 1,000 W
- Weight
- 25.3 lb
Value context: The lowest captured direct price in this 1kWh group, paired with 1,000W solar input. The missing general surge rating remains the main value tradeoff for motor loads.
- Best for
- A solar-supported refrigerator plan where high panel input matters more than a published surge figure.
- Skip it if
- You need a manufacturer-published general surge rating before attempting a compressor load.
What works
- 1,000W maximum solar input
- Low captured direct price
- 25.3 lb body
Tradeoffs
- No separate general surge rating found in the current US manual
- Power Lifting is not counted as compressor-start support
Best for output headroom
Anker SOLIX C1000 Gen 2
Why it ranks here
The highest continuous AC output in this 1kWh group, paired with a fast manufacturer-stated AC recharge mode.
- Direct price
- $529.99
- Rated capacity
- 1,024 Wh
- Continuous AC
- 2,000 W
- Published peak
- 3,000 W
- Solar input
- 600 W
- Weight
- 24.9 lb
Value context: A low captured direct price for the highest continuous output in this 1kWh group. The tradeoff is a fixed, non-expandable 1,024Wh capacity.
- Best for
- A refrigerator that shares the station with additional short-duration household loads.
- Skip it if
- Expandable capacity matters more than output or recharge speed.
What works
- 2,000W continuous AC output
- Published 3,000W peak
- 24.9 lb body with 49-minute fast-charge claim
Tradeoffs
- Capacity is not expandable
- Solar input is lower than EcoFlow and BLUETTI

Calculation: rated capacity × 80% after reserve × 88% AC efficiency × 95% environmental factor, divided by the cycling average load.
These are conservative planning inputs, not a universal refrigerator specification. Automatic defrost, room temperature, door openings, and the exact compressor can materially change the result.
Solar refill floor is rated capacity divided by maximum published solar input. It excludes weather, panel angle, temperature, charge taper, and conversion losses. Runtime does not prove voltage, startup, transfer, wiring, medical, flood-prevention, or combustion safety compatibility.
Research method
How we ranked refrigerator backup stations
The ranking starts with electrical compatibility, then separates products by the practical reason a refrigerator owner would choose one over another.
We compare official specifications, manuals, support records, current manufacturer pricing, and transparent planning calculations. We do not assign lab scores or claim hands-on testing that did not occur.
- Compressor startup
- A separately published peak rating is useful evidence, but the exact refrigerator start still needs verification.
- Usable energy
- Rated capacity is compared within a narrow class, then adjusted through the site calculator rather than treated as delivered AC energy.
- Recharge plan
- Solar input, AC recharge, and expansion matter only when the outage plan can use them.
- Portability and value
- Weight and current direct price decide whether added capability is worth carrying and paying for.

Every eligible completed product record in this guide's capacity class appears in the ranking. This does not mean every power station on the market was reviewed, and the list is never padded with models whose critical evidence is incomplete.
- Planning capacity

- Startup gate
- Model specificA compressor start can disqualify a station that otherwise has enough capacity.
- Food-safety clock

Questions that change the decision
Is a 1,000Wh power station enough for a refrigerator?
Often, but not universally. The station must clear compressor startup and hold enough usable energy for the refrigerator's measured daily consumption plus reserve.
Should I buy the model with the highest inverter output?
Only when your refrigerator or shared load needs that headroom. After startup is covered, usable energy, recharge access, weight, and price may matter more.
