How we assign awards →The differences that matter
- 1.024 kWh vs 3.072 kWh → a 1000 W load lasts about an hour against three.
- 1800 W vs 3600 W continuous → two kitchen appliances together exceed the EcoFlow's limit; the Jackery carries them.
- 500 W vs 1000 W solar input → with full sun a full recharge takes about two hours against three: the small one fills sooner but holds a third of the energy.
- Expandable up to 5 kWh vs not expandable → the EcoFlow can grow, the Jackery stays as it is.
Which one to choose
Choose EcoFlow DELTA 3 if…
you want a 12.5 kg battery with four mains outlets, for a weekend away or for a PC and router in a blackout, and one you can expand up to 5 kWh. A 1000 W load lasts about an hour and above 1800 W it will not cope; it carries a five-year warranty and switches over as a UPS in 10 ms.
Choose Jackery Explorer 3000 v2 if…
you want to power loads up to 3600 W together, with surges of 7200 W, and hold a 1000 W load for about three hours. It cannot be expanded, weighs 27 kg, has three mains outlets and a three-year warranty.
