EcoFlow and Jackery are two of the biggest names in portable power, and their 1 kWh stations are the ones most people compare. The short answer: choose the Jackery Explorer 1000 v2 if you want the lightest, simplest 1 kWh station. Choose the EcoFlow DELTA 2 if you want more output, room to expand and a feature-rich app. Both use LiFePO4 batteries and both can handle essentials like a fridge, router and lights during an outage.
Below we compare the two models side by side, so you can decide which one fits your home, your budget and the way you will use it.
Note: EcoFlow has also released newer DELTA 3 models. We compare the DELTA 2 here because it is widely available and often discounted, but check the current EcoFlow lineup before you buy.

Capacity and Battery Life
On paper the two stations are almost identical in size: 1,070 Wh for the Jackery and 1,024 Wh for the EcoFlow, a difference of less than 5%. Both use LiFePO4 chemistry, which is built for many more charge cycles than older lithium-ion packs. (If you want to understand why that matters, read our guide on LiFePO4 vs Lithium-Ion Power Stations.)
The rated cycle life is where they differ. Jackery lists about 4,000 cycles to 70% capacity, while EcoFlow lists about 3,000 cycles to 80%. Those ratings use different end points, so they are not a perfect apples-to-apples comparison. In practice, either battery should last for many years of occasional backup use.
Output Power: What Can Each One Run?
This is where EcoFlow has a clear edge. The DELTA 2 delivers up to 1,800 W continuous, compared with 1,500 W for the Jackery. That 300 W difference matters for a few appliances:
- Both can run: refrigerators (including startup surge), routers, lights, laptops, TVs, CPAP machines, fans and most kitchen appliances such as a microwave or blender.
- EcoFlow has more headroom for: 1,500 W appliances such as a space heater or hair dryer that sit right at the Jackery’s limit, and for running several devices at once.
- Neither is a good fit for: running heaters, ovens or air conditioners for long, because they drain a 1 kWh battery in under an hour.
The Jackery does list a higher momentary surge rating, which can help motors start, such as a refrigerator compressor. If your main concern is a single motor load, either unit should be fine. If you plan to run several things at once, the EcoFlow gives you more breathing room.
Charging Speed and Solar
Both stations charge quickly from a wall outlet. EcoFlow rates the DELTA 2 at around 80% in about 50 minutes, and Jackery rates the Explorer 1000 v2 at roughly one hour for a full charge. For outages, that means you can top up between short power cuts.
Both accept solar panels, so you can recharge during a longer outage. Solar input limits and the number of solar ports vary, so check the current specs for the panels you plan to use. For help with panels, see our guide on How Many Solar Panels Do I Need to Charge a Power Station?
Weight and Portability
The Jackery Explorer 1000 v2 is the lighter of the two at about 23.8 lb, while the DELTA 2 weighs in the high 20s (listings vary by source and region). A few pounds sounds small, but it adds up when you carry the unit up stairs, to the car or around a campsite. If you will move your power station often, the Jackery is easier to live with.
Expandability and Smart Features
This is the EcoFlow’s second big advantage. The DELTA 2 can be paired with an extra battery to add capacity later, so you can start small and grow your system. The Jackery Explorer 1000 v2 is a standalone unit with no expansion option, so what you buy is what you get.
EcoFlow’s app also offers detailed monitoring, charge scheduling and remote control. Jackery’s app covers the basics, and many buyers like the Jackery’s simplicity. If you enjoy tweaking settings or want automation, EcoFlow wins. If you want a station you can plug in and forget, Jackery is easier.
Warranty and Support
EcoFlow currently lists a 5-year warranty on the DELTA 2, while Jackery lists 3 years plus 2 more when you register the product. On paper both can add up to 5 years, but the terms differ, so read the warranty on the product page before you buy.
Price and Value
Prices for both models change often, and both are frequently discounted around major sales events. Compare the price per watt-hour (price divided by capacity) when you shop. The DELTA 2 often has the lower sticker price, while the Jackery sometimes costs more in exchange for lighter weight and simplicity.

Frequently Asked Questions
Is EcoFlow better than Jackery?
Neither is better for everyone. EcoFlow tends to offer more output, expandability and app features. Jackery tends to offer lighter weight and a simpler experience. The right choice depends on your priorities.
Which one charges faster?
Both recharge from a wall outlet in around an hour for most of the capacity. EcoFlow lists about 80% in roughly 50 minutes, and Jackery lists a full charge in about one hour.
Can either one run a refrigerator?
Yes. Both can run a typical refrigerator for roughly half a day or more, depending on the model and how often the compressor runs. Check our guide on How Long Will a Power Station Run a Refrigerator? for runtimes.
Can I add more battery later?
With the EcoFlow DELTA 2, yes: it supports an extra battery. The Jackery Explorer 1000 v2 is a standalone unit with no expansion option.
Final Verdict
If you want the most capability and room to grow, the EcoFlow DELTA 2 is the stronger choice thanks to its higher output, expandability and app. If you want the easiest, lightest 1 kWh station, the Jackery Explorer 1000 v2 is hard to beat. For a typical outage kit, either will keep your essentials running.
