Jackery Explorer 1000 Plus vs EcoFlow DELTA 3 Plus
Jackery Explorer 1000 Plus (1,264 Wh, 2,000 W) vs EcoFlow DELTA 3 Plus (1,024 Wh, 1,800 W). The Explorer 1000 Plus has the bigger battery, so it runs your devices longer. Here is where each one comes out ahead, based on the manufacturers' published specs.
Each row has its own scale, and the longer bar fills the row. Figures are the manufacturers' published specs.
Choose the Explorer 1000 Plus for…
- longer runtime: 23% more battery (1,264 Wh vs 1,024 Wh)
- high-power appliances: 2,000 W vs 1,800 W continuous output
Choose the DELTA 3 Plus for…
- faster solar charging: up to 1,000 W vs 800 W of panels
- UPS use: 10 ms switchover vs 20 ms
- portability: 4.4 lb lighter (27.6 lb)
- fast wall charging: 1,500 W vs 1,200 W AC input

Our verdict
If runtime is all you care about, the Jackery wins. Its battery is 1,264 Wh against 1,024 Wh, about 23% more, which our calculator turns into roughly 18 and a half hours on a typical fridge against 15. It's also rated higher for output: 2,000 W continuous and 4,000 W surge, against 1,800 W and 3,600 W.
Almost everything else favors the EcoFlow. The DELTA 3 Plus takes 1,000 W of solar against 800 W, charges from the wall at 1,500 W against 1,200 W and switches over in 10 ms against 20 ms. It has 140 W USB-C instead of 100 W and six AC outlets instead of three. And it's 4.4 lb lighter, 27.6 lb against 32 lb.
Expansion is where you need to look closely. On paper both grow to about 5 kWh. But Jackery has discontinued its Battery Pack 1000 Plus, so the 1000 Plus's upgrade path may not be there when you want it. EcoFlow lists its extra batteries as compatible with the DELTA 3 Plus.
So: buy the 1000 Plus if you want the most runtime from one box and you're fine with it staying that size. Buy the DELTA 3 Plus if you care about solar, fast charging or adding capacity later.
How we compared: the makers' published specs plus our runtime calculations. We haven't bench-tested these units ourselves.
