Output: DELTA 2 runs more at once

1,800 W continuous vs 1,500 W means the DELTA 2 has more room for a microwave or several appliances simultaneously. The Jackery's 3,000 W surge peak is higher, which helps with brief motor start-up spikes.

Portability: Jackery is smaller and lighter

About 3 lb lighter and noticeably more compact — a real difference when carrying to a campsite.

Capacity and expansion

Base capacity is nearly identical. The decisive difference for outage planning: DELTA 2 can add an extra battery; the Jackery 1000 v2 cannot. Not sure how much you need? Use our sizing guide. Backing up a CPAP? Both cover roughly two heated-humidifier nights; see our CPAP power station guide.

Longevity

Both use LiFePO4 cells (see why that matters). The cycle ratings use different end-of-life thresholds (80% vs 70%), so treat both as long-lived rather than declaring a winner.
