DELTA 3 Plus and Explorer 1000 v2

These two published claims sit near 1,000 watt-hours. They are not the same battery. Capacity, continuous watts, and surge watts answer different questions. This page does not pick a winner, and it does not list a price.

The EcoFlow DELTA 3 Plus claim used here is 1,024 Wh, 1,800 W continuous, and 3,600 W surge. The Jackery Explorer 1000 v2 claim used here is 1,070 Wh, 1,500 W continuous, and 3,000 W surge. On a pure watt-hour sort, the Explorer figure is slightly larger. On the published continuous rating, the DELTA 3 Plus figure is larger. Which difference matters depends on your startup watts and your duration, which this page does not know.

Source check on November 7, 2026

The DELTA 3 Plus specifications block matched 1,024 Wh and 1,800 W total with a 3,600 W surge. Another sentence on that page pairs 2,200 W with X-Boost and the same surge. X-Boost is not the continuous rating in this comparison.

The Explorer 1000 v2 specifications row matched 1,070 Wh, 1,500 W rated, and 3,000 W surge. The product description on that same page says 1,024 Wh. The calculator uses 1,070 Wh from the specifications row, and the card also shows the 1,024 Wh sentence.

Neither check was a bench test. “Handles a refrigerator” language on a manufacturer page is their statement, not a result from KeepCold Backup.

Run both through your own kWh on the calculator. For the larger pair, see the 2,000 Wh-class comparison.
