How we assign awards →The differences that matter
- 2.05 → 3.07 kWh: with a 1,000 W load, about one hour more runtime on the Jackery.
- 2,400 → 3,600 W continuous: above 2,400 W the DELTA 3 Max is not enough.
- 4,800 → 7,200 W peak: the Jackery handles heavier start-ups.
- 500 → 1,000 W solar input: the Jackery takes more panels, so it recharges from the sun in less time.
