Choosing portable power in the residential outdoor power equipment space often comes down to one fork: do you need whole-home backup that can handle heavy appliances, or a lighter station for weekends, short outages, and electronics? The four EcoFlow listings here split cleanly into two camps. Two are DELTA Pro Ultra 12kWh stations aimed at whole-home power-cut backup, and two are DELTA 3 stations aimed at more portable use.
Quick take
The two DELTA Pro Ultra 12kWh listings share the same headline power specs and differ mainly by listed price and condition wording: one is the lower-priced DELTA Pro Ultra, and the other carries Certified Refurbished in its title. On the portable side, the DELTA 3 Classic and DELTA 3 Plus offer the same core capacity and output, but the Plus adds extra AC outlets, faster AC charging, and a longer rated cycle life.

Product notes
EcoFlow DELTA Pro Ultra 12kWh LiFePo4 Power Station, Whole Home Power-cut Backup
If whole-home backup is the goal, this is the lower-priced way into the DELTA Pro Ultra 12kWh platform at USD 4,799.00. The core unit provides 6144Wh and can be expanded to 90kWh, with 120V/240V output totaling 7200W. That output is what lets you think about heavier appliances during a power-cut, and the LFP chemistry is rated for 3500 cycles to 80%+ capacity over a 10-year span. The trade-off: it does not carry the Certified Refurbished label that appears on the other DELTA Pro Ultra listing. If that wording matters to you, the Certified Refurbished listing is the one to consider.
EcoFlow DELTA Pro Ultra 12kWh Power Station Lifepo4, Certified Refurbished
This is the DELTA Pro Ultra 12kWh listing with Certified Refurbished stated directly in the title. It has the same 6144Wh core capacity, 90kWh expansion limit, 7200W total output, and 120V/240V support as the other DELTA Pro Ultra, so the choice between the two comes down to whether you want that certification wording for USD 200 more. The listed price is USD 4,999.00, making it the highest price in this comparison. If you are shopping for whole-home backup and the certification label is the deciding factor, this listing is the one that states it.
EcoFlow 1024Wh 1800W DELTA 3 Classic LiFePO4 PPortable Power Station for Backup
At USD 486.25, this is the entry point to the DELTA 3 family. It offers 1024Wh of capacity and 1800W output, with a 3600W surge and X-Boost expansion up to 2600W for heavier loads. The LiFePO4 cells are rated for 3000+ cycles, and the unit includes Wi-Fi and Bluetooth communication. For camping, weekend trips, or keeping essentials running during a short outage, it covers a lot of ground at a lower listed price than the other 1024Wh station here. The limit is capacity: 1024Wh is enough for portable essentials, which is a different class from the DELTA Pro Ultra units aimed at whole-home backup.
EcoFlow DELTA 3 Plus 1024Wh 1800W Portable Power Station LFP Battery Refurbished
This station shares the 1024Wh capacity and 1800W output with the DELTA 3 Classic, but it comes with six AC outlets and a 3600W surge, so it is easier to plug in several devices at once. Charging is another differentiator: 1500W AC input brings it to 80% in around 40 minutes, and the LFP battery is rated for 4000 cycles to 80% capacity. The battery pack also carries an IP65 rating for splash, dust, and oil resistance. The listed price is USD 598.75, which is USD 112.50 more than the DELTA 3 Classic. That extra amount buys more outlets, faster AC charging, and a longer rated cycle life.
Final recommendation by use case
- For whole-home backup at a lower listed price, choose the DELTA Pro Ultra 12kWh that is not the Certified Refurbished listing.
- If you want the Certified Refurbished wording in the title, pick the other DELTA Pro Ultra 12kWh.
- For a portable station that leaves the most budget room, go with the DELTA 3 Classic.
- For more AC outlets and faster AC charging in a portable station, go with the DELTA 3 Plus.
