A home backup power station has one job: keep your refrigerator, internet, medical devices and lights running through a power outage until the grid comes back. The right size depends on what you need to run and for how long, not on the biggest number printed on the box.
We compared the home backup models from Jackery, EcoFlow, BLUETTI and Anker SOLIX that are on sale in the US right now, using each brand’s spec sheet (checked September 27, 2026) and our own runtime math, to find the best portable power station for home backup at each level of need: a short blackout, a multi-day outage after a hurricane or winter storm, or whole-home backup. BackupPowerHub doesn’t run lab tests (see our editorial guidelines), so every runtime on this page is a calculation you can check. Prices update automatically from each brand’s store.
- EcoFlow DELTA Pro Ultra: best whole-home system, 7,200W and up to 90kWh.
- Anker SOLIX F3800: best for 240V appliances and EV charging, 6,000W split-phase.
- EcoFlow DELTA Pro 3: best all-rounder, 120/240V and 80% in 50 minutes from the wall.
- Jackery Explorer 5000 Plus: biggest all-in-one battery, 5,040Wh and 7,200W.
- Jackery HomePower 3600 Plus: best to start small and expand, 3,584Wh now and up to 21.5kWh.
- BLUETTI Apex 300: best modular system, from 2.8kWh to 58kWh.
- BLUETTI Elite 200 V2: best budget pick for essentials, 2,073.6Wh.

How Much Capacity Does Your Home Need?
Start with what must keep running in an emergency, then pick the output and capacity to match. Most homes fall into one of three groups.
Essentials
Refrigerator, Wi-Fi, lights, phones and a CPAP. All 120V, low power.
Look for: 2 to 4kWh and at least 2,000W.
Essentials + 240V
Add a well pump, a 240V space heater or a window AC on a dedicated circuit.
Look for: 240V output, 4 to 8kWh and 4,000W or more.
Whole home
Central AC, electric range, dryer, several circuits at once.
Look for: 7,200W or more, 10kWh or more and a smart panel.
The 0.85 factor accounts for inverter losses, so it gives you the energy you can actually use. In the picks below, we use two reference loads: a full-size fridge averaging 120W, and a 300W essentials load (fridge, internet, LED lights, phone charging and a CPAP). Your own mix will differ, so run your devices through the power station calculator before you buy, or read what size power station you need.

#1 EcoFlow DELTA Pro Ultra: Best Whole-Home System
EcoFlow DELTA Pro Ultra
6,144Wh · 7,200W output · Lowest tracked: $3,989 (Oct 8)
Lowest we have tracked
Built to grow into a true whole-home system, up to 21.6kW and 90kWh.
See the deal on EcoFlow Read our reviewThe DELTA Pro Ultra is built like a home battery that happens to have wheels. The inverter and the 6,144Wh battery are two separate boxes, and you add batteries (up to 90kWh) or inverters (up to 21.6kW) as your needs grow. One inverter delivers 7,200W at 120/240V, which EcoFlow says is enough for a house with central AC.
Pair it with the EcoFlow Smart Home Panel 2 and it switches over automatically when the grid fails, circuit by circuit. EcoFlow says it is the only portable power station certified to both UL 1973 and UL 9540, and the battery heats itself below 32°F.

How to Connect a Power Station to Your Home
Plug the fridge and a power strip straight into the station. No electrician, works with every pick.
Feeds selected circuits from a 240V outlet such as a NEMA 14-50 or L14-30. Installed by an electrician.
Panels such as the EcoFlow Smart Home Panel 2 switch over automatically when the grid fails. Jackery’s Smart Transfer Switch pairs with the Explorer 5000 Plus.
Never plug a power station into a wall outlet to backfeed your house. It can energize the utility lines and injure line workers. Any connection to your panel must go through a transfer switch or an interlock installed by a licensed electrician. Our transfer switch installation guide explains the options and the questions to ask.
Power Station or Gas Generator?
Power station
- Safe to run indoors: no exhaust, no carbon monoxide
- Silent, with no fuel to store
- Switches over automatically, fast enough for computers and CPAP machines
- Recharges from solar during a long outage
Gas generator
- Runs as long as you have fuel
- Lower upfront cost per watt
- Must run outdoors, away from windows
- Needs fuel runs and maintenance
Many homes end up with both: a power station for silent, instant backup and a generator to recharge it when the outage runs into days. The DELTA Pro 3 and DELTA Pro Ultra support EcoFlow’s dual-fuel Smart Generator for exactly that. For longer events, see our multi-day outage planning guide.

Frequently Asked Questions
What is the best portable power station for home backup?
It depends on what you need to run. For most homes, the EcoFlow DELTA Pro 3 covers essentials and 240V loads with room to grow to 48kWh. For whole-home backup with central AC, the EcoFlow DELTA Pro Ultra scales to 90kWh. For a well pump or EV charging, the Anker SOLIX F3800 delivers 6,000W at 240V. If you only need the refrigerator, internet and lights, the BLUETTI Elite 200 V2 does the job for much less.
What size power station do I need for home backup?
For essentials, 2 to 4kWh is a good range: a fridge, internet and some lights (about 200W) run for roughly 8 to 17 hours on that. A fridge averaging 120W runs about 15 hours on a 2,073.6Wh unit and about 25 hours on a 3,584Wh unit. Add a well pump or other 240V loads and you need 240V output and 4kWh or more. For your exact devices, use the power station calculator.
Can a portable power station run a whole house?
A few can, with the right setup. The EcoFlow DELTA Pro Ultra delivers 7,200W per inverter and scales to 21.6kW and 90kWh, and the Jackery Explorer 5000 Plus delivers 7,200W at 120/240V. Running central AC, an electric range and a dryer at once still takes a smart panel and more than one battery. For most homes, backing up essential circuits is the realistic goal.
Do I need 240V for home backup?
Only if you need to run 240V loads such as a well pump, central AC, an electric dryer or an EV charger. Among our picks, the DELTA Pro Ultra, F3800, DELTA Pro 3, Explorer 5000 Plus and Apex 300 provide 240V from one unit. The HomePower 3600 Plus needs two linked units, and the Elite 200 V2 is 120V only.
Can I connect a power station to my electrical panel?
Yes, through a transfer switch, an interlock kit or a smart panel installed by a licensed electrician. Never backfeed through a regular wall outlet. See our transfer switch installation guide.
How long will a power station run during a power outage?
Divide the usable capacity (about 85% of the rated watt-hours) by the load. A refrigerator averaging 120W runs about 15 hours on 2,073.6Wh, about 25 hours on 3,584Wh and about 44 hours on 6,144Wh. With several devices running, runtime drops fast: a 300W essentials load gets about 6, 10 and 17 hours on the same three units. Solar panels or a generator stretch that during a multi-day blackout.
How long does a home backup power station last?
The picks here use LiFePO4 batteries rated from 3,000 cycles (Anker SOLIX F3800) to 6,000 cycles (BLUETTI Apex 300 and Elite 200 V2, Jackery HomePower 3600 Plus). A home backup unit that sits on standby and runs through a handful of outages a year will take many years to use those cycles.
Can I recharge with solar during an outage?
Yes, all seven accept solar panels. Solar input ranges from 1,000W (HomePower 3600 Plus, Elite 200 V2) to 5,600W per inverter (DELTA Pro Ultra). The higher the input, the faster you refill during a sunny day between outages.
