These three are the large portable power stations most often shortlisted for home backup. All use LFP batteries and carry a 5-year warranty, but they differ in ways that matter once the power goes out: whether you can add batteries, whether they supply 240 V, how fast solar refills them and what each watt-hour costs.
Quick answer
EcoFlow DELTA Pro 3 is the most complete single unit: 4,096 Wh[src], 4,000 W at 120 V or 240 V, expandable and rated for 4,000 cycles to 80%. Anker SOLIX F3800 Plus is cheaper on sale, takes the most solar (3,200 W[src]) and expands furthest, but delivers 3,300 W as a single unit. Jackery HomePower 3000 costs the least ($1,349 on sale) and weighs about half as much, but it is 120 V only and cannot be expanded.
Key takeaways
- Capacity: DELTA Pro 3 4,096 Wh, F3800 Plus 3,840 Wh, HomePower 3000 3,072 Wh.
- Expansion: EcoFlow lists systems up to 48 kWh, Anker up to 53.8 kWh; Jackery none.
- 240 V output: EcoFlow and Anker yes; Jackery no.
- Solar input: Anker 3,200 W, EcoFlow 2,600 W, Jackery 1,000 W.
- Price per Wh on sale: Jackery $0.44, Anker $0.62, EcoFlow $0.68.

Capacity and expansion
Out of the box, the DELTA Pro 3 holds the most energy, with the F3800 Plus close behind and the HomePower 3000 about a quarter smaller. For a fridge alone that is the difference between roughly two days and a day and a half on one charge.
The bigger gap is what happens next. EcoFlow sells extra batteries for the DELTA Pro 3 and lists a range of 4 to 48 kWh. Anker sells 3.84 kWh expansion batteries (up to six per F3800 Plus) and lists systems of up to 53.8 kWh. The largest figures from both makers involve linking more than one unit, so check the configuration before you count on them. Jackery’s FAQ says the HomePower 3000 cannot take expansion batteries; it points buyers who want that to other models. If you might want more backup later, that rules the Jackery out.
Power and 240 V appliances
Most household outlets are 120 V, but well pumps, central air, electric dryers and some heat pumps need 240 V. Both the DELTA Pro 3 and the F3800 Plus can supply it:
- EcoFlow delivers up to 4,000 W from a single unit. Its FAQ explains that it switches between a 120 V mode and a 240 V mode, so you cannot use both sets of outlets at once.
- Anker advertises 6,000 W, but its product page notes this needs at least one expansion battery: a single F3800 Plus delivers 3,300 W. Anker also notes that the 240 V output cannot be used while the unit charges from a 120 V outlet.
- Jackery offers 3,600 W continuous and 7,200 W surge, but only at 120 V.
All three can feed selected house circuits through a manual transfer switch or the maker’s home panel, which an electrician should install.
Charging from solar and the wall
In a multi-day outage, recharging speed decides how much of your stored energy you get back each day. Anker accepts up to 3,200 W of solar, EcoFlow up to 2,600 W (across a high-voltage and a low-voltage input) and Jackery up to 1,000 W. Those are maximums: you need that many watts of panels in full sun to reach them, and real output in an outage is usually far lower.
From a standard 120 V outlet, EcoFlow lists 2,000 W of charging and Jackery quotes 2.2 hours for a full AC charge. Anker can also charge from a 240 V outlet or a 240 V generator at up to 6,000 W.
UPS: keeping devices on when the grid drops
All three can act as an uninterruptible power supply for devices plugged into them. EcoFlow quotes a 10 ms switchover and Jackery about 20 ms. Anker lists UPS operation for some of its 120 V outlets but does not publish a switchover time. For computers and routers, any of these is usually fine; for medical equipment, check with the device maker and the station’s manual first.
Price, cycle life and weight
| Model | Price on sale | Price per Wh | Rated cycles | Weight |
|---|---|---|---|---|
| EcoFlow DELTA Pro 3 | $2,799 | $0.68 | 4,000 to 80% | 113.5 lb |
| Anker SOLIX F3800 Plus | $2,399.99 | $0.62 | 3,000+ (retention not stated) | 136.7 lb |
| Jackery HomePower 3000 | $1,349 | $0.44 | 4,000 to 70% | 59.5 lb |
The Jackery is the cheapest per watt-hour by a clear margin and by far the lightest. The DELTA Pro 3 costs the most per watt-hour, but its rating of 4,000 cycles to 80% capacity is the strongest of the three. Anker lists 3,000+ cycles without stating the remaining capacity, and at 136.7 lb it is the heaviest.
