EcoFlow Power Stations and Solar Generators: Which Model to Buy

Quick answer

EcoFlow’s US lineup in our catalog is the DELTA 3 family: the 1,024 Wh DELTA 3 for camping and short outages, the 2,048 Wh DELTA 3 Max Plus for RVs and home offices, and the 3,072 Wh Ultra Plus and 4,096 Wh DELTA Pro 3 for home backup. All declare a 5-year warranty and expansion.

EcoFlow’s US lineup in our catalog is the DELTA 3 family: four stations from 1,024 Wh to 4,096 Wh, plus two solar kits built on the DELTA 3. Every model declares LiFePO4 cells, a 5-year warranty and an expansion path. This page covers what each model offers on paper and which one to pick.

We have not tested these units. Every figure comes from the Amazon listing, and we point out where EcoFlow leaves a spec out.

What are EcoFlow’s strengths on paper?

Consistent warranties, strong output and expansion on every station.

  • Expansion everywhere. The DELTA 3 grows to 5,000 Wh, the Max Plus to 10,000 Wh, the Ultra Plus to 11,000 Wh and the DELTA Pro 3 to 48,000 Wh.
  • Fast UPS on the bigger units. The Max Plus, Ultra Plus and Pro 3 each declare a 10 ms switchover.
  • High output per kWh. The Max Plus delivers 3,000 W from 2,048 Wh, more than most 2 kWh stations we list.
  • 5-year warranty on every EcoFlow station and kit in our catalog.

Where are the gaps?

Missing solar and cycle data on the larger models, and no UPS time on the DELTA 3. The Max Plus, Ultra Plus and DELTA Pro 3 listings do not publish maximum solar input or cycle life. That makes it hard to plan a large solar array from the listing alone.

The DELTA 3 publishes solar input (500 W) and cycles (4,000) but no UPS switchover time. Weight also climbs quickly: the DELTA Pro 3 weighs 52.2 kg (115.1 lb).

Which EcoFlow should I buy?

Pick by use, not by the biggest number.

What should I check before buying an EcoFlow?

Confirm solar input, expansion packs and weight for the model you want. For the Max Plus, Ultra Plus and DELTA Pro 3, read the solar input limit in the manual before buying panels, since the listings leave it out. If you plan to expand, check which extra battery packs EcoFlow lists as compatible with your exact model; packs are sold separately and are not in our catalog.

Finally, weigh the carry. The DELTA 3 at 12.5 kg (27.6 lb) is a one-person lift, the Max Plus at 22.2 kg (48.9 lb) is a firm two-hand carry, and the two biggest units are best kept in one place.

How does EcoFlow compare with other brands?

It has the widest size range with a declared UPS and expansion. Jackery’s Explorer 2000 v2 is lighter per kWh, and Anker’s F3000 publishes much higher solar input. Compare them on the Jackery and Anker SOLIX pages, or see every brand ranked together in the best portable power stations.

Frequently asked questions

Which EcoFlow power station is best for most people?

The DELTA 3. It pairs 1,024 Wh and 1,800 W with 500 W of solar input at 12.5 kg (27.6 lb), and it expands to 5,000 Wh.

Which EcoFlow models have a UPS?

The DELTA 3 Max Plus, DELTA 3 Ultra Plus and DELTA Pro 3 listings declare a 10 ms switchover. The DELTA 3 listing does not state a UPS time.

Are EcoFlow power stations LiFePO4?

Yes. Every EcoFlow station and kit in our US catalog declares LiFePO4 (LFP) cells.

What is the difference between the EcoFlow DELTA 3 kits?

Both bundle the same DELTA 3 station; one adds a 160 W panel and the other a 220 W panel. The 220 W kit refills the station faster from the sun.
