The differences that matter
- Capacity 1.024 kWh vs 2.042 kWh → at a 1000 W load, in theory and without losses, about 1 hour vs about 2 hours.
- Expandable to 5 kWh vs not expandable → the EcoFlow grows with need, the Jackery stays at its starting capacity.
- Mains outlets 4 vs 2 → four appliances plugged in directly, no power strip.
- Warranty 5 years vs 3 → at one cycle a day the cover lasts 1825 cycles vs 1095, fewer than the 4000 both declare.
Which one to choose
Choose EcoFlow DELTA 3 if…
you plug up to four appliances in directly and want to add capacity later. It weighs 12.5 kg against 17.5 and its solar input reaches 500 W, against 400 W. You accept starting from a single kWh and 1800 W continuous instead of 2200.
Choose Jackery Explorer 2000 v2 if…
you want the whole store in one block and loads of up to 2200 W continuous (4400 W peak), with a declared 0–80% recharge in 52 minutes. You accept fewer mains outlets, no expansion and 5 kg more.
