Best Portable Power Stations to Run a Refrigerator
Yes — a portable power station can run a refrigerator. It's one of the most common home-backup jobs for these units. But a fridge is trickier than a laptop: the compressor pulls a big startup surge, and it cycles on and off all day. The two specs that matter are surge output (can it start the compressor?) and capacity in Wh (how long can it keep cycling?). Every pick below is checked against both.
What a fridge actually draws
Published wattage figures and appliance label data give you three common fridge types:
- Mini / dorm fridges: ~40–80W running, with a modest startup bump of a few hundred watts. Easy for almost any 1kWh-class station.
- Full-size kitchen fridges: ~100–200W running, with a compressor startup surge of ~800–1,200W (sometimes more on older units). The surge is the gatekeeper — a station rated under ~800W surge can trip and shut off when the compressor kicks.
- Chest freezers: ~100–150W running with a similar compressor surge. They cycle less often than fridges, which stretches runtime.
One more thing that matters: fridges don't run constantly. The compressor cycles on roughly a third of the time once the box is cold. So a fridge drawing 150W while running averages closer to ~50W over a day — which is why the runtime estimates below look better than raw division would suggest. Estimates use the standard formula:
If your fridge is old, oversized, or you don't know its wattage, check the label inside the door or on the back — and read our sizing guide for the full math walkthrough.

The 5 picks
EcoFlow RIVER 2 Pro
The spec sheet lists 768Wh of LiFePO4 capacity with 800W of continuous output and a 1,600W surge (via EcoFlow's X-Boost). For a mini fridge drawing ~40–80W, that's comfortable headroom: the surge rating covers the small compressor's startup bump, and the capacity stretches to roughly a day of cycling for a small box. It's also the lightest and cheapest pick here at ~17–18 lbs (sources differ slightly; EcoFlow lists 7.8 kg), which makes it easy to move from the kitchen to a dorm or RV. The headline feature is recharge speed — EcoFlow's X-Stream AC input refills it 0–100% in about 70 minutes, so between outages it bounces back fast.
Pros
- 1,600W surge handles mini-fridge compressor startup
- LiFePO4 cells rated 3,000 cycles to 80% capacity
- ~70-minute AC recharge is best-in-class
- Lightest pick (~17–18 lbs)
Cons
- 768Wh won't carry a full-size fridge long
- 220W solar input ceiling limits off-grid refills
- Not expandable
Jackery Explorer 1000 v2
Jackery's published specs give the Explorer 1000 v2 a 1,070Wh LiFePO4 battery, 1,500W of continuous output, and a 3,000W surge. That surge rating is the standout: it's the most surge headroom in this lineup short of the 1,800W-output units, and it covers full-size fridge compressor startups with room to spare. The LFP chemistry is rated for 4,000 cycles (to ~70% capacity) — the longest cycle life on this page — and the unit weighs about 23.8 lbs, light for a 1kWh station. Standard AC charging takes around 1.7 hours, and there's a published sub-20ms UPS switchover, so a fridge plugged through it won't notice a grid blip.
Pros
- 3,000W surge is plenty for fridge compressor startup
- 4,000-cycle LFP battery — longest life here
- ~23.8 lbs, genuinely portable for the capacity
- UPS-grade switchover (published at under 20ms)
Cons
- Not expandable — capacity is fixed at 1,070Wh
- 400W solar input max
BLUETTI AC180
The AC180's spec sheet shows 1,152Wh of LiFePO4 capacity with an 1,800W continuous pure sine wave inverter and 2,700W of surge — the strongest combination here for a full-size fridge, which needs to clear that ~800–1,200W compressor startup without tripping. BLUETTI rates the battery at 3,500+ cycles to 80%, and the 1,440W turbo AC charging refills the unit in about 1.3 hours. It also takes up to 500W of solar and has a published ≤20ms UPS switchover, so it can sit inline between the wall and your fridge. The trade-off is weight: at about 35.3 lbs it's the heaviest pick on this page, so it's a garage-or-pantry unit rather than a grab-and-go.

Pros
- 1,800W / 2,700W handles full-size fridge surge easily
- 1,152Wh — largest capacity of the fixed units here
- 3,500+ cycle LFP battery
- 500W solar input; ~1.3-hour turbo AC recharge
Cons
- ~35.3 lbs — heaviest pick here
- Not expandable
Anker SOLIX C1000
Anker's published specs list a 1,056Wh LiFePO4 battery, 1,800W continuous output, and 2,400W surge via its SurgePad mode — enough to start a full-size fridge compressor. Two things set it apart in this lineup. First, recharge speed: Anker's HyperFlash AC input refills the unit 0–100% in about 58 minutes, the fastest here — useful when the power flickers back on briefly mid-outage. Second, a published sub-20ms UPS switchover, so it can sit between the wall and the fridge and take over before the compressor notices. The unit weighs about 28.4 lbs and accepts up to 600W of solar. If you think you may need more than a day, Anker sells an expansion battery that doubles the C1000 to 2,112Wh.
Pros
- ~58-minute full recharge is the fastest here
- 1,800W / 2,400W surge covers full-size fridges
- Sub-20ms UPS switchover for inline use
- Expandable to 2,112Wh with Anker's battery pack
Cons
- ~28.4 lbs — middling portability
- Expansion battery adds significant cost
EcoFlow DELTA 2
EcoFlow's spec sheet lists 1,024Wh of LiFePO4 capacity, 1,800W of continuous output, and a 2,700W surge — full-size-fridge capable on both axes. The differentiator is expansion: the DELTA 2 accepts EcoFlow's extra batteries, growing from 1,024Wh to about 3,072Wh with the larger pack — the only pick here that scales into genuine multi-day fridge coverage. It also charges fast on AC (0–80% in about 50 minutes via X-Stream), takes up to 500W of solar, and weighs about 27 lbs. If your outage scenario is "the grid might be down for days," this is the pick that grows with the problem instead of capping out at 1kWh.
Pros
- Expandable to ~3kWh — multi-day fridge runtime
- 1,800W / 2,700W surge handles full-size compressors
- 3,000-cycle LFP battery
- Very fast AC charging (~50 min to 80%)
Cons
- Extra battery is sold separately and costs extra
- Base capacity is the smallest of the 1kWh picks
Fridge runtime estimates
These are estimates from spec math (Wh × 0.85 ÷ watts), assuming the fridge starts cold and the compressor cycles roughly one-third of the time. Real runtime varies with ambient temperature, how often the door opens, and the fridge's age.
| Station | Mini fridge (~60W running) | Full-size fridge (~150W running, ~1/3 duty cycle) | Chest freezer (~125W running, ~1/3 duty cycle) |
|---|---|---|---|
| EcoFlow RIVER 2 Pro (768Wh) | ~11 hrs | ~13 hrs | ~15 hrs |
| Jackery Explorer 1000 v2 (1,070Wh) | ~15 hrs | ~18 hrs | ~22 hrs |
| BLUETTI AC180 (1,152Wh) | ~16 hrs | ~20 hrs | ~23 hrs |
| Anker SOLIX C1000 (1,056Wh) | ~15 hrs | ~18 hrs | ~21 hrs |
| EcoFlow DELTA 2 (1,024Wh, ~3kWh w/ expansion) | ~14 hrs (up to ~44 hrs) | ~17 hrs (up to ~52 hrs) | ~20 hrs (up to ~62 hrs) |
Estimates only — labeled as such because fridges vary. A hot garage, frequent door opening, or an older compressor can cut these figures noticeably.
Before you buy: three checks
For keeping the station itself recharged during a long outage, see our solar generator for blackouts guide — every pick here accepts solar, but input limits (220W on the RIVER 2 Pro vs. 600W on the SOLIX C1000) decide how fast it refills. If you're comparing these stations for general home backup rather than fridges specifically, our home backup guide covers the broader load-planning picture, and a dedicated 12V cooler is worth a look for camping or road trips — see best 12V portable fridges.
