How to choose
What to check before buying a home battery backup Watt-hour capacity and continuous output watts determine which devices a unit can run and for how long. A 1000Wh station covers a refrigerator for several hours, while a 2000Wh-plus unit like the Bluetti AC200L or Anker SOLIX F2000 stretches into multi-day territory. Recharge speed on AC power matters too, since a station that refills in under an hour handles back-to-back outages better than one needing several hours.
Portable power station or whole-home UPS? Camping trips, garages, and rolling blackouts favor portable stations like the Jackery Explorer 1000 v2 or EcoFlow DELTA 2, since power needs to move with you. A UPS such as the APC Back-UPS Pro BR1500MS2 stays plugged in permanently and switches instantly when grid power drops, which matters more for computers and medical monitors than for appliances. Mobility versus instant, always-on protection is the real tradeoff between the two.
Matching capacity to household size and budget Renters or smaller households covering just phones, routers, and a lamp can get by with something like the Jackery Explorer 300 Plus at a fraction of the cost of larger stations. A sump pump, CPAP machine, or medical refrigeration pushes the requirement to at least 1000Wh, ideally with an expandable system such as the Bluetti AC200L. Undersizing a battery backup to save money means it fails exactly when it’s needed most.
Solar charging for off-grid backup Input wattage matters more than raw battery capacity for anyone planning to recharge via solar during extended outages. Up to 600W of solar input, with Goal Zero’s boost accessory, cuts recharge time significantly on the Yeti 1500X compared to standard panels alone. Off-grid cabins and disaster-prone regions benefit most from this pairing, since grid recharging isn’t guaranteed to be available.

Good to know
What size battery backup do I need for my home?
Most households need at least 1000Wh to run a refrigerator, phone chargers, and a few lights for several hours. Homes relying on medical equipment or a sump pump should look at 1500Wh to 2000Wh or larger, expandable options like the Bluetti AC200L.
How long does a home battery backup last during an outage?
Runtime depends on what’s plugged in. A 1000Wh unit like the EcoFlow DELTA 2 can power a refrigerator for roughly 8 to 10 hours, but that drops sharply once a space heater or other high-draw device joins the load.
Portable power station vs UPS, which is better for home backup?
A portable power station like the Jackery Explorer 1000 v2 covers appliances and larger loads during extended outages. A UPS like the APC Back-UPS Pro BR1500MS2 switches instantly for computers and medical devices but only lasts minutes, not hours.
Can a battery backup run a refrigerator?
Yes. Units with 1000Wh or more and at least 1500W continuous output, such as the EcoFlow DELTA 2 or Jackery Explorer 1000 v2, can run a standard refrigerator for multiple hours per charge.
Is a whole-home battery backup worth it?
For homes in areas with frequent multi-day outages, an expandable system like the Anker SOLIX F2000 or Bluetti AC200L justifies the higher upfront cost. Occasional short outages may not justify the expense over a smaller portable unit.
What’s the best battery backup for medical devices like CPAP machines?
A UPS with instant switchover, such as the APC Back-UPS Pro BR1500MS2, or a portable station with pure sine wave output like the EcoFlow DELTA 2, both work well for CPAP and other sensitive medical electronics.
Can I recharge a battery backup with solar panels?
Most modern power stations accept solar input, but capacity varies widely. The Goal Zero Yeti 1500X accepts up to 600W with its boost accessory, making it one of the faster options for solar recharging.
What’s the best budget battery backup for home use?
The Jackery Explorer 300 Plus offers the lowest cost of entry here, covering phones, routers, and small electronics, though its 288Wh capacity isn’t enough for major appliances.
How is a battery backup different from a generator?
A battery backup switches on instantly and runs silently indoors, unlike a fuel generator that needs ventilation and refueling. Capacity limits mean most battery units suit shorter outages better than multi-day generator runtime.
Do battery backups work for CPAP machines overnight?
Most CPAP machines draw under 60W, so a 1000Wh unit like the EcoFlow DELTA 2 can typically run one for multiple nights between recharges, though exact runtime depends on the specific machine and humidifier settings.
Our pick
The EcoFlow DELTA 2 is the strongest all-around pick, pairing fast AC recharging with enough output for a refrigerator and multiple devices at once. Households needing multi-day, whole-home coverage should choose the Bluetti AC200L instead, since its expandable battery packs handle extended outages the DELTA 2 can’t match. Anyone on a tight budget covering just phones and a lamp will do fine with the Jackery Explorer 300 Plus.
