These are the two most cross-shopped 1,000Wh power stations on the market, and they're closer than the spec sheet suggests — both are LiFePO4, both run a CPAP for ~14–15 hours, both start a typical fridge. The decision comes down to three real differences.

Output and headroom. The Delta 2's 1,800W (2,700W surge) gives more room to run high-wattage gear than the Jackery's 1,500W (3,000W surge). If you'll push a microwave, kettle, or several big draws at once, the EcoFlow has the edge — understand why peak draw matters in Surge Watts vs Running Watts.

Battery life. The Jackery's 4,000-cycle rating beats the Delta 2's 3,000. Over a decade of regular use that's a real gap, and it's the spec that decides long-term value — see LiFePO4 vs NMC.

Weight and software. The Jackery is ~3 lbs lighter and easier to find at retail (simpler returns). The Delta 2's app is the best in the category for live power monitoring and is expandable with extra batteries.

Both also come as solar bundles — see the Delta 2 Solar Generator (currently $684.00) and Jackery 1000 v2 Solar Generator (currently $699.00) if you want a panel included.
