Home Battery Power Backup: 5 Best Picks for Outages in 2026

By Lauren Holland

Updated November 2026

If you are looking for home battery power backup, the main question is how many watt-hours you need to keep the essentials running when the grid goes down. A refrigerator, a CPAP machine, a sump pump and a few lights can draw very different amounts of energy, and the right unit depends on how long you want to stay powered and how much you can recharge between outages. The picks below were chosen by checking manufacturer specifications, brand reputation for battery life and safety, and the usage patterns owners commonly describe. We have not tested these units ourselves, so treat the specs as manufacturer-stated figures and verify them against your own loads.

Buying Guide

Capacity in watt-hours

Add up the wattage of each device you need, multiply by hours of use, and sum the results. Divide by about 0.85 to account for conversion losses. A refrigerator averaging around 100 to 150 watts running 24 hours can consume roughly 1 to 3.6kWh per day depending on the model and compressor cycling. Check your appliance nameplate and any energy guide label.

Continuous and surge output

Refrigerators, well pumps and sump pumps have motor starting surges that can be several times their running wattage. Confirm the unit’s surge rating against the locked-rotor amps on your pump label.

Battery chemistry

LiFePO4 and LFP batteries are widely associated with long cycle life and stable thermal behavior compared with some other lithium chemistries. Check the manufacturer’s stated cycle rating if longevity matters to you.

Recharge options

Look at AC wall charging speed, and whether the unit accepts solar input. Fast charge helps you recover between storms, while solar extends runtime for multi-day outages. Confirm the maximum input wattage listed by the manufacturer.

Portability and size

Measure where the unit will sit. Larger expandable systems are heavier and may need a dedicated spot, while compact units can be moved between rooms or carried to a car during an evacuation.

Protection and switchover

If you run computers or networking gear, check switchover time. Some units advertise UPS-style switching in milliseconds, which can prevent reboots. This matters less for a refrigerator, which tolerates brief interruptions.

Safe operation and care

Never run a portable power station indoors near flammable materials, keep it dry and ventilated, and do not connect it to your home wiring unless a licensed electrician installs an appropriate transfer switch. Store the battery at moderate temperatures and recharge it periodically during long storage.

FAQ

How long will a home battery power backup run a refrigerator?

It depends on the refrigerator’s average daily consumption and the battery’s usable capacity. A rough estimate is watt-hours divided by average wattage, then reduced for conversion losses. Check your refrigerator’s energy label for daily kWh and plan accordingly.

Can a portable unit run a CPAP overnight?

Many CPAP machines draw modest power, so a mid-size battery can often cover a night. Confirm your device’s wattage on its label and consult your sleep provider or medical equipment supplier before relying on any backup for medical use.

Can I run a sump pump on battery backup?

Yes, if the unit’s surge rating covers the pump’s starting current and its capacity covers the expected run time during heavy rain. Sump pumps can run frequently in storms, so calculate for a realistic duty cycle and consult a licensed electrician about a dedicated circuit.

Do I need a transfer switch?

To power household circuits directly, a transfer switch installed by a licensed electrician is the safe method. Plugging a generator or power station into a wall outlet can create dangerous backfeed to utility lines.

How often should I recharge the battery?

Recharge after each use and periodically during long storage, following the manufacturer’s guidance. Keeping a lithium battery at a moderate charge level generally helps preserve capacity over time.

Is a UPS the same as a power station?

No. A UPS is designed for short backup of electronics and surge protection, while a power station stores more energy for appliances over longer periods. Choose based on what you need to run and for how long.

Conclusion

For most households, home battery power backup starts with a clear list of essential loads and realistic outage durations. The Jackery HomePower 3600 Plus Power Station suits whole-essentials backup, the Jackery Explorer 300 Portable Power Station fits a bedroom or small kitchen, and the EF ECOFLOW Delta 3 Portable Power Station works for a home office with some appliances.
