EcoFlow vs Jackery is the most common brand question in portable power stations, and for good reason: they make the two best-known lineups. The short version is that Jackery leans toward light, simple, portable units, and EcoFlow leans toward more output and systems you can expand for home backup.
We compare them below using the models we track. We have not tested these stations ourselves. Figures are manufacturer specs and retailer prices, which change often.
Head to head: the 1 kWh models
Most buyers compare the EcoFlow DELTA 3 and Jackery Explorer 1000 v2. They hold almost the same amount of energy and both use long-life LiFePO4 batteries.
| Jackery Explorer 1000 v2 | EcoFlow DELTA 3 | |
|---|---|---|
| Listed price | $499 | $599 |
| Capacity | 1,070 Wh | 1,024 Wh |
| AC output | 1,500 W | 1,800 W |
| Wall recharge (rated) | 60 min | 56 min |
| Max solar input | 400 W | 500 W |
| Expandable | No | Yes, to 5 kWh |
| Weight | 23.8 lb | Check listing |
Where Jackery wins: price and weight. At 23.8 lb, the Explorer 1000 v2 is easy to carry to a campsite or move between rooms, and it's usually the cheaper of the two.
Where EcoFlow wins: output and growth. 1,800 W runs more at once, such as a microwave or a space heater on low, and EcoFlow's X-Boost mode can run some resistive loads above the rated output. You can also add batteries later to reach 5 kWh, which matters for home backup.
Smaller and larger options
Both brands cover more than the 1 kWh class.
- Small and light: Jackery Explorer 300. 292 Wh, 300 W output, and 7.5 lb for $259. Enough to charge phones, laptops, cameras, and run a fan or CPAP overnight. See the Jackery Explorer 300.
- Whole-home scale: EcoFlow DELTA Pro. 3,600 Wh and 3,600 W output, expandable well beyond that and compatible with a transfer switch. It weighs 99 lb, so it stays put. See the EcoFlow DELTA Pro.
Which brand fits your use
- Camping, van life, and tailgating: Jackery. Lighter units at lower prices, and the Explorer 1000 v2 covers a weekend of lights, phones, and a cooler.
- Home backup: EcoFlow. Higher output and the ability to add batteries means you can size it for the outage you actually expect.
- Jobsite: EcoFlow's higher output handles saws and compressors better, but check the surge rating of your tools first.
- Solar charging: EcoFlow takes more solar input, so it refills faster from panels on a long trip.
How long will 1 kWh last?
Roughly, divide the station's capacity by what you're running, then take off about 15 percent for conversion losses. A 1,000 Wh station running a 60 W router and a 150 W average fridge load lasts about 4 hours. Add a few LED lights and phone charging and plan on 3 to 4 hours. For multi-day outages you need several kWh, which is where expandable EcoFlow systems or a larger home backup station come in.
The bottom line
Buy the Jackery Explorer 1000 v2 if you want the lightest, simplest 1 kWh station at a lower price, mostly for camping and short outages. Buy the EcoFlow DELTA 3 if you want more output, faster solar charging, and room to expand for home backup. For more options from Bluetti and Anker, see our best portable power stations page.
