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.
- Solar input 1000 W vs 400 W → in theory, in full sun and without losses, about 1 hour to fill the EcoFlow and about 5 hours for the Jackery.
- Warranty 5 years vs 3 → at one cycle a day the cover lasts 1825 cycles vs 1095.
Which one to choose
Choose EcoFlow DELTA 3 Plus if…
you start from 1 kWh and want room to grow, or you have plenty of panels to use up in one morning. It weighs 12.5 kg against 17.5 and its USB-C reaches 140 W (100 W on the Jackery). You accept a smaller store and 1800 W continuous instead of 2200.
Choose Jackery Explorer 2000 v2 if…
you want the big store in a single block and loads of up to 2200 W continuous (4400 W peak), with a declared 0–80% recharge in 52 minutes. You accept no expansion, slower solar charging and 5 kg more to carry.
