EcoFlow DELTA 3 Plus vs Jackery Explorer 1000 v2
Technical comparison · Home backup
Two home stations of about 1 kWh with LFP cells: solar input and room to grow settle it. One takes up to 1000 W of panels and can be expanded; the other stops at 400 W and stays as it is. Power figures are declared by the manufacturer.

The differences that matter
- Solar input 1000 W vs 400 W → in theory, in full sun and without losses, the EcoFlow fills in about 1 hour, the Jackery in about 3.
- Expandable to 5 kWh vs fixed capacity → the EcoFlow grows with your consumption; the Jackery has to be replaced.
- Switchover 10 ms (UPS) vs 20 ms with a gap (EPS) → the EcoFlow is built to keep supply uninterrupted; the Jackery declares a brief pause.
- Warranty 5 years vs 3 → at one cycle a day the cover lasts 1825 cycles vs 1095, fewer than the 4000 declared: the years decide, not the cycles.
Which one to choose
Choose EcoFlow DELTA 3 Plus if…
you need up to 1800 W (the Jackery stops at 1500 W) and want a unit that can grow instead of being replaced when 1 kWh is no longer enough. The trade-off is 12.5 kg to carry instead of 10.8.
Choose Jackery Explorer 1000 v2 if…
you move it often and every kilo counts: 10.8 kg, 22 dB declared and two mains outlets. You accept slower solar charging, no expansion and a short gap in supply when the grid drops.
