Best home battery backup power station

A home battery backup power station is a portable battery with an inverter big enough to feed a house, usually through an inlet box or a transfer switch an electrician installs. The question is not which one is best. It is how much of the house you want back, for how long, and who will move the box.

The five below start at 2,764.8 Wh and 83.78 lb and end at a system that can reach 90 kWh. If a fridge and the Wi-Fi are the whole job, the refrigerator guide sizes a far smaller unit. The runtime table turns any of these capacities into hours for common loads, by arithmetic.

Capacity, output and cycle life are the makers' ratings on their own terms, not HoldBackup tests. Anker publishes no surge figure for the F3800 Plus, and BLUETTI's 7,680 W is what it calls lifting power. The DELTA Pro Ultra's weight is two pieces; every other unit is one.

BLUETTI Apex 300

Sold as: BLUETTI Apex 300 Portable Power Station 2764.8Wh 3840W LFP Solar Generator | Battery Backup with 6 3840W AC Ports (7680W Surge), Simultaneous 120V/240V Output & Black Start

The lightest 240 V unit here, and the longest-rated battery: BLUETTI rates it at 6,000 or more cycles to 80%, with 3,840 W of output and 7,680 W of what BLUETTI calls lifting power, from a 14-50R at 120/240 V. It takes up to six B300K or B500K batteries, and three units with eighteen batteries reach 11.52 kW and 58 kWh. Its own solar ports are 2 × 1,200 W at up to 60 V; more needs the SolarX 4K. Turbo charging reaches 80% in BLUETTI's 45 minutes through the P050A port.

How we chose

Split-phase 120/240 V output, so an inlet box or transfer switch can feed the house, and whether both voltages run at once.
Watt-hours and the makers' path to more: how many batteries, and how many units, before the system tops out.
Continuous and surge watts against a furnace blower, a well pump or a compressor start.
Solar input, because a multi-day outage is a recharge problem.
Switchover time as stated, for a desktop or a CPAP on the station.
Weight, because every one of these has to get into the house once.
Warranty as stated for the US, and any CPSC notice: we found none for these five units.

Every number is the maker's, from the spec page or manual linked beside it. HoldBackup has no lab, so nothing on this page was tested by us, and Amazon sets the price the button shows.

Owner lines summarize public forum threads, linked beside them. We don't verify what owners say.

Questions

What does 240 V output get me that a 120 V power station doesn't?

A well pump, a furnace with a 240 V blower, a central air handler or an electric water heater runs on 240 V, and so does an inlet box or transfer switch wired for the whole panel. A 120 V station covers a fridge, lights, the network and a gas furnace's blower on cords. Every unit on this page gives 120 and 240 V. EcoFlow says the DELTA Pro 3 does one at a time, and BLUETTI's page and manual disagree about the Apex 300; the cards quote both.

How long will one of these run a house?

Divide the watt-hours by what you draw. A load averaging 150 W on a 4,000 Wh station comes to about 26 hours before inverter losses, by arithmetic, not a test, and a furnace blower or a well pump shortens that fast. The runtime table on this site does the same arithmetic for common loads.

Do I need an electrician?

For an inlet box, a transfer switch or a smart panel, yes: those connect to the house wiring, and the makers' own kits say so. Plugging appliances into the station on cords needs no one. Never feed a station into a wall outlet.

Are these the same as a Tesla Powerwall?

No. A Powerwall, a FranklinWH or an Enphase battery is a permanently installed system sized and permitted by an installer. The units here plug in, roll on wheels, and can leave with you. HoldBackup writes about the portable kind only.

Where does the price button go?

Straight to Amazon. Amazon sets the price and availability, and both can change.
