The differences that matter
Manufacturer-declared values. - Expandability → DELTA 3 grows to 5 kWh; Explorer 1000 v2 cannot be expanded. - Continuous output, 1800 vs 1500 W → a 1600 W load runs on the first and exceeds the limit of the second. - Warranty, 5 years vs 3 → the warranty, not the 4000 cycles both declare, is what runs out first. - Noise, 30 vs 22 dB → the second suits an occupied room better.
Which one to choose
Choose EcoFlow DELTA 3 if…
you want to start at 1 kWh and add batteries later, or run several devices at once from four outlets. You carry 1.7 kg more.
Choose Jackery Explorer 1000 v2 if…
the unit sits in a room where people live and quiet counts more than output, or you move it often and every kilo shows. You give up expansion and have only two mains outlets.
