Two of the most popular 1kWh power stations take very different approaches. The Jackery Explorer 1000 V2 bets on light weight, a lower price, and simple portability. The EcoFlow DELTA 3 Plus bets on higher output, much faster solar charging, and room to grow with extra batteries. Here is how they compare on the numbers that matter.
Key Specifications
- Jackery Explorer 1000 V2 capacity: 1,070Wh LiFePO4, 4,000 cycles to 70%
- Jackery AC output: 1,500W continuous, 3,000W surge
- Jackery charging: 0 to 100% in 1 hour in emergency mode via the app, about 1.7 hours standard; 400W max solar input
- Jackery weight: 23.8 lbs
- Jackery price: US$499 at Jackery.com, checked October 26, 2026 (list US$559)
- EcoFlow DELTA 3 Plus capacity: 1,024Wh LiFePO4, 4,000 cycles to 80%, expandable to 5kWh with extra batteries
- EcoFlow AC output: 1,800W continuous, 3,600W surge, X-Boost up to 2,400W
- EcoFlow charging: 0 to 100% in 56 minutes on AC; 1,000W max solar input across two 500W inputs
- EcoFlow weight: 27.6 lbs
- EcoFlow price: US$699 at REI, checked October 26, 2026
What Stands Out
The Jackery is the easier unit to live with day to day. It is almost 4 lbs lighter, has a fold-flat handle, and costs about US$200 less, yet it still holds slightly more energy at 1,070Wh. For a home office, a fridge during a short outage, or camping weekends, that combination is hard to argue with.
The EcoFlow is the stronger performer. Its 1,800W inverter runs loads the Jackery cannot, like many kettles and larger microwaves, and the under-10ms UPS switchover keeps a desktop or network gear running through a blackout. The 1,000W solar input is the biggest gap in this comparison: in good sun the DELTA 3 Plus can refill from solar in about 70 minutes, while the Jackery caps at 400W. Add the option to expand to 5kWh later, and the EcoFlow is the one that can grow from a camping unit into a small home backup system.
Things to Know
The Jackery battery is not expandable, so what you buy is what you get. Its 1-hour charge also needs emergency mode switched on in the app, with standard charging closer to 1.7 hours. The EcoFlow costs more, weighs more, and its expansion batteries add real money on top of the US$699 starting price. Both units carry 5-year warranties and use long-life LiFePO4 cells.
Who Is It Best For?
Pick the Jackery Explorer 1000 V2 if you want the lightest, simplest, best-value 1kWh station for outages, road trips, and camping. Pick the EcoFlow DELTA 3 Plus if you need the higher output, plan to charge from solar often, want true UPS behaviour for a home office, or like the idea of adding capacity later.
Verdict
On value and portability, the Jackery wins. On output, solar speed, and flexibility, the EcoFlow wins. If your budget is firm and your loads are modest, take the Jackery and the savings. If you will push the inverter hard or build a bigger system over time, the DELTA 3 Plus earns its premium.
