When the power goes out for most of a day, the losses add up fast: a freezer full of food, a basement that floods when the sump pump stops, a modem that takes your work offline. That is the case for a portable power station on a small property. Not camping or tailgating, but keeping a few essentials running until the grid comes back. Well pumps are a special case, because most need a 240V source; our solar generator for a well pump guide covers the units that can run one.
The technology has improved a lot in the last few years. Every unit here uses a LiFePO4 (lithium iron phosphate) battery rated for 3,000 to 4,000 charge cycles, where older NMC stations were typically rated for about 500 to 800. LiFePO4 is also much less prone to thermal runaway. For a backup unit that spends most of its life waiting for an emergency, that long cycle life and safety margin make it the chemistry to choose.
Here’s what actually matters when choosing one. Capacity (Wh) tells you how long it runs. A full-size fridge typically uses about 1 to 2 kWh a day (check its EnergyGuide label), and a 1000Wh unit delivers roughly 800Wh after conversion losses, so expect about half a day to most of a day. Continuous output (W) tells you what you can run at all. Surge rating covers the brief spike when a motor starts: a fridge that runs at roughly 100 to 200W can need roughly 600 to 1,200W for a moment to start its compressor, so a unit with too little surge headroom will trip even with a full battery. Power Lifting, X-Boost and SurgePad modes are different: they run heating appliances at reduced power and do not help start motors. And recharge speed matters when grid power flickers back briefly or you’re topping up from solar between cloudy days.
Below are six units we recommend for small-property backup, from a budget overnight unit to a high-capacity station.
EcoFlow DELTA 3
The DELTA 3 is our pick if you want one power station that does most of what a small property needs. It hits the center of the market with 1024Wh of LiFePO4 capacity and 1800W of continuous AC output. That continuous rating gives common household essentials plenty of running headroom. Startup requirements still vary by appliance, so check the starting watts on any refrigerator, freezer, or pump against the unit’s operating guidance.
After conversion losses, the 1024Wh battery delivers roughly 800Wh to AC loads, enough to run a typical fridge for about half a day or a bit more, depending on its EnergyGuide rating and how often the door opens. If you need more runtime, the system expands up to 5kWh using compatible EcoFlow battery packs. For a one-or-two-room essentials setup during an outage, running the fridge, the modem and router, phone chargers, and a few lights, the DELTA 3 is the practical sweet spot.
Recharge speed is the other standout. With up to 1500W of AC input, it reaches a full charge in about 56 minutes. It also accepts up to 500W of solar input. The LiFePO4 cells are rated for 4,000 cycles to 80% capacity and a 10-year lifespan, and the battery pack is rated IP65.
The practical trade-off is capacity. The base unit is still a 1024Wh power station, so multi-day coverage calls for compatible expansion, and solar input tops out at 500W. Buy it for fast wall charging and an expansion path, then size that path to the outage you actually need to cover.
EcoFlow RIVER 3 Max
Not everyone needs to run a refrigerator. If your outage plan is “keep the lights on, charge the phones, run the modem so I can work, and power a CPAP overnight,” the RIVER 3 Max covers that in a lower price tier than a 1kWh unit. It comes as two pieces: a 286Wh RIVER 3 Plus station and a 286Wh extra battery that clips onto it, for 572Wh in all (EcoFlow’s RIVER 3 page lists it that way). Unclip the battery and the station alone weighs 10.4 pounds.
The LiFePO4 cells are rated for 3,000 cycles to 80% capacity. Rated AC output is 600W across three outlets, plus a 100W USB-C port and a car outlet, and the extra battery adds a 140W USB-C port. EcoFlow lists X-Boost up to 1,200W, but like the other boost modes above, it runs heating appliances at reduced power and does not start motors. That’s the limit to respect: this is a small-device unit, not a fridge unit.
For a renter, an apartment, or as a second small unit next to a larger one, it is an easy first buy. Just be realistic about what 572Wh means. A typical 10 to 20W router plus a couple of LED bulbs runs for roughly 10 hours or more, and a steady 60W load for about 6 to 8 hours, but it won’t carry a refrigerator through a long outage.
Anker SOLIX C1000
If your single biggest worry in an outage is the refrigerator, the Anker SOLIX C1000 is a strong fit for the job. It packs 1056Wh of LiFePO4 capacity and 1800W of continuous output. Anker also lists a 2400W SurgePad rating, but its SurgePad explainer says that mode is for heating appliances and is not recommended for motor-driven appliances such as refrigerators. For a fridge, the 1800W continuous rating is the number to use: it sits above the roughly 600 to 1,200W starting draw commonly estimated for household fridges and chest freezers, though you should check your model’s rating. Like the DELTA 3, the capacity covers roughly half a day or more of fridge runtime, depending on the model.
The C1000 is compact for its capacity: about 28 pounds and a little smaller than the DELTA 3, though not lighter. Recharging is quick, roughly 43 minutes to 80% on AC once fast charging is set in the Anker app. It’s expandable to 2112Wh with the add-on battery, so if a day of fridge runtime isn’t enough you can extend it into a multi-day setup without buying a whole new unit.
Anker backs it with a five-year warranty, and the eleven ports cover essentially anything you’d plug in during an outage. The two real downsides are cost-related: the expansion battery is a meaningful additional spend, and a few of the smarter features (like setting charge limits to preserve battery health) live in the app rather than on the unit itself. For a fridge-first backup plan, though, this is the one to beat.
Anker SOLIX C2000 Gen 2
When 1kWh isn’t enough, the Anker SOLIX C2000 Gen 2 is where serious backup begins. It carries 2,048Wh of LiFePO4 capacity (twice the units above) and 2,400W of rated output, which gives running headroom for bigger 120V loads such as a sump pump. Motors still need a start-up burst, so check your pump’s starting watts against Anker’s spec before you count on it. It is a 120V-only unit, so it cannot run a 240V well pump, which is what most submersible well pumps are; our well-pump guide covers the units that can.
The TT-30 RV outlet is a tell about who this is for. With an inlet and transfer switch installed by a licensed electrician, it can power selected 120V household circuits instead of running extension cords. And with Anker’s add-on battery it grows to about 4kWh, enough to stretch a multi-day outage if you’re recharging from solar during the day.
It accepts up to 800W of solar input and reaches a full charge in about 88 minutes on AC, per Anker’s spec sheet. The trade-offs are physical and financial. At about 42 pounds it’s a two-hand lift, not something you carry room to room all day. And it costs considerably more than a 1kWh unit. But for longer outages and bigger 120V loads, it is the step up from the 1kWh class.
Bluetti AC180
The AC180 is a good base for a small solar backup kit. With 1152Wh of LiFePO4 capacity and 1800W output (2700W surge), it covers the same fridge-and-essentials duty as the DELTA 3. It accepts up to 500W of solar input, the same as the DELTA 3, so a pair of 200-watt panels can refill much of the battery on a sunny day. Panels are sold separately.
That matters for off-grid use and for outages that stretch past a single day. A power station alone is a battery; once it’s empty during a multi-day grid failure, it’s a paperweight unless you can recharge it. Solar input solves that, and the AC180’s recharge flexibility (AC, solar, car, or generator) gives you options when the grid is down for a while.
On AC it hits 0-80% in 45 minutes, matching the fastest units here. Four AC outlets and 11 outputs in total cover a typical essentials load. The catch is that the solar panels are a separate purchase, so budget for them, and there’s only one USB-C PD port, which feels stingy in 2026. As a standalone backup unit it’s perfectly good; as the heart of a small solar setup, it’s excellent.
Jackery Explorer 1000 v2
The Explorer 1000 v2 is the most plug-and-play unit on this list: turn it on, plug in, done. Everyday use needs no app, with clear labeling and a layout that makes sense the first time you look at it. For someone buying their first power station who feels intimidated by specs, that simplicity has real value.
The v2 is a genuine upgrade over the original. It now uses a 1070Wh LiFePO4 battery (the old version was NMC), with 1500W continuous output and a 3000W surge. At about 23.8 pounds it’s the lightest of the 1kWh-class units here, which makes it easy to move room to room. A 1-hour emergency charge mode, switched on in the Jackery app, is useful when grid power comes back briefly.
The one spec to weigh is the 1500W continuous ceiling. It’s plenty for a fridge, a freezer, most power tools, and a coffee maker, but it’s lower than the 1800W units, so a high-draw space heater or a large microwave can push it. And the 1000 v2 is not expandable, so it’s not a “grow into it” platform. For a straightforward, reliable, easy-to-use first backup unit, though, it’s hard to go wrong.
How We Picked These
We compared manufacturer specifications, manuals and warranty terms using these criteria:
Battery chemistry. We only considered units with LiFePO4 (LFP) cells. For a backup unit that spends most of its life in storage, LFP’s 3,000+ cycle ratings and lower thermal-runaway risk make it the better choice over older NMC chemistry.
Output that matches real loads. A power station is useless if it trips when your fridge compressor starts. We weighed continuous output and surge ratings against the startup demands of refrigerators, freezers and sump pumps. Well pumps, which are usually 240V, get their own guide.
Capacity for the intended use. We judged each unit within its tier. A 572Wh budget unit is here for how well it handles lights and devices, not for whether it can run a fridge for a day.
Recharge flexibility. AC recharge speed matters when the grid flickers back briefly. Solar input matters for outages that outlast the battery. We favored units that recharge fast and from multiple sources.
Brand reliability and support. These are emergency tools. We stuck with established brands (EcoFlow, Anker, Bluetti, Jackery) that publish full specifications and warranty terms.
