Jackery and EcoFlow are often the first two names people compare. Both now use LFP batteries across their main ranges. The differences show up in weight, UPS behaviour, charging and how far each brand scales toward whole-home backup. Based on manufacturer specs and public reviews.
Jackery for the lightest 1 kWh unit and a modular mid-size path (2000 Plus). EcoFlow for the shortest UPS switchover and single-unit 240V whole-home backup (DELTA Pro 3).
1 kWh class: Explorer 1000 v2 vs DELTA 3 Plus
| Model | Capacity | Output | Solar in | Voltage | UPS |
|---|---|---|---|---|---|
| Jackery Explorer 1000 v2 | 1,070 Wh | 1,500 W | check | 120V | about 20 ms |
| EcoFlow DELTA 3 Plus | 1,024 Wh | 1,800 W | 500 W | 120V | < 10 ms |
"check" = not confirmed on the sources we used; verify on the manufacturer page before buying.
- Weight: 23.8 lb (Jackery) vs 27.6 lb (EcoFlow).
- Output: 1,500 W vs 1,800 W continuous: the EcoFlow handles a microwave or kettle more comfortably.
- UPS: about 20 ms vs under 10 ms.
- Wall charging: about 1 h 40 min (about 1 h in app emergency mode) vs about 56 min.
Bigger systems: Explorer 2000 Plus vs DELTA Pro 3
| Model | Capacity | Output | Solar in | Voltage | UPS |
|---|---|---|---|---|---|
| Jackery Explorer 2000 Plus | 2,042 Wh | 3,000 W | check | 120V (240V by pairing two units) | See spec sheet |
| EcoFlow DELTA Pro 3 | 4,096 Wh | 4,000 W | 2,600 W | 120V / 240V | < 10 ms |
"check" = not confirmed on the sources we used; verify on the manufacturer page before buying.
These are different philosophies. The 2000 Plus starts at 2 kWh and 3,000 W and grows with battery packs; 240V needs two linked units. The DELTA Pro 3 is a single 4 kWh, 4,000 W, 120/240V unit from day one. If you know you need 240V for a well pump, the DELTA Pro 3 is simpler; if you want to start smaller and grow, the 2000 Plus is more flexible.

Portable power stations are designed to be used plug-in, like an appliance. Anything wired into your home (inlet box, transfer switch, sub-panel, batteries feeding a circuit) must be installed by a qualified, licensed electrician and comply with local code. Never backfeed a house through an ordinary outlet.
