The EcoFlow DELTA 3 wins on raw capability — more continuous AC output and faster charging — and is the pick if you want to run power tools or a full-size appliance. The Jackery Explorer 1000 v2 is the friendlier, quieter unit for camping and light backup. Both use LiFePO4, so both should last years rather than seasons.
How We Picked
We put these two head to head at the same capacity class — 1024Wh for the EcoFlow, 1070Wh for the Jackery — so the comparison is about design rather than size. We looked at continuous AC output, surge headroom, charge speed from wall and solar, battery chemistry, and how each behaves as part of a larger off-grid setup. If you want the wider field rather than a two-way comparison, see our guides to portable power stations, solar generators for home backup, and portable solar panels.
1. Best for Output & Speed: EF ECOFLOW DELTA 3 Portable Power Station (1024Wh)
EF ECOFLOW DELTA 3 Portable Power Station (1024Wh)
EcoFlow
- 1024Wh LiFePO4 battery
- 1800W continuous AC output
- Fast full recharge from a wall outlet
- Expandable with add-on battery
- 4.8★ from 1,331 owners
Why we picked it: The DELTA 3 is the more capable of the two in the ways that decide whether a power station is useful on a work site or in a real outage. Eighteen hundred watts of continuous AC runs a circular saw, a full-size microwave, or a space heater — loads that a 1500W unit will refuse. Wall recharging is fast enough that you can top it up in the gap between outages, and it takes an expansion battery if 1kWh stops being enough. At 4.8 stars from over 1,300 owners it is also the better-reviewed unit here.
2. Best for Camping & Simplicity: Jackery Explorer 1000 v2 Portable Power Station with Carrying Bag
Jackery Explorer 1000 v2 Portable Power Station with Carrying Bag
Jackery
- 1070Wh LiFePO4 battery
- 1500W continuous AC output
- Slightly larger battery than the DELTA 3
- Ships with a carrying bag
- 4.7★ from 137 owners
Why we picked it: Jackery's advantage has always been that the unit gets out of your way — simple controls, a quiet fan profile, and a carry handle that makes a 1kWh box feel portable. This version has a marginally larger battery than the DELTA 3 and moves to LiFePO4, which is the important upgrade over older Jackery models that used a shorter-lived chemistry. Fifteen hundred watts covers camp cooking, CPAP, laptops, and lighting comfortably; it is only when you reach for a power tool that the ceiling matters.
Comparison Table
| Pick | Power station | Capacity | Continuous AC | Best for |
|---|---|---|---|---|
| Best for Output & Speed | EcoFlow DELTA 3 | 1024Wh / 1800W continuous | LiFePO4 | Best for tools and heavy loads |
| Best for Camping & Simplicity | Jackery Explorer 1000 v2 | 1070Wh / 1500W continuous | LiFePO4 | Best for camping and light backup |
What to Look For
Capacity versus output. These are two different numbers and both matter. Capacity (watt-hours) is how long it runs; continuous output (watts) is what it can run at all. These two units are within 50Wh of each other on capacity, so the real difference is the 1800W versus 1500W output ceiling.
Battery chemistry. Both of these use LiFePO4, which is the specification to insist on. It is rated for thousands of cycles rather than the several hundred typical of the older lithium-ion chemistry in earlier power stations, and it is more tolerant of being left at partial charge.
Charge speed. How fast a station refills decides whether it is useful in a rolling outage or a short burst of sun. Wall charging speed is where EcoFlow has generally led; both accept solar input, and both benefit from panels sized near their maximum input rather than a single small panel.
Expandability. A power station you can add a second battery to has a longer useful life than one you cannot, because your loads tend to grow. Check whether the model you are buying supports an expansion battery before you commit to the ecosystem.
Bottom Line: Which Should You Buy?
The better all-rounder: the EcoFlow DELTA 3. Best for tools and heavy loads.
The alternative: the Jackery Explorer 1000 v2. Best for camping and light backup.

Frequently Asked Questions
Is EcoFlow better than Jackery?
At the 1kWh size, EcoFlow's DELTA 3 is the more capable unit — 1800W of continuous output against Jackery's 1500W, plus faster wall charging and battery expansion. Jackery's Explorer 1000 v2 is simpler and easier to carry, which suits camping better. Neither is a bad buy; they are optimised differently.
Do EcoFlow and Jackery use the same batteries?
Both of these models use LiFePO4 (lithium iron phosphate), which is rated for thousands of cycles. Older Jackery and EcoFlow units used a shorter-lived lithium-ion chemistry, so check the specification rather than assuming — chemistry is the single biggest predictor of how many years you get.
Can either one run a refrigerator?
Yes. A household refrigerator running at 150 to 200 watts is well within both units' continuous output, and roughly 1kWh of storage will carry a modern fridge through most of a day depending on how often it is opened.
How long do these power stations last?
LiFePO4 cells in this class are typically rated for several thousand charge cycles to 80% of original capacity — realistically a decade of weekend use, or several years of daily cycling. Keeping the unit out of extreme heat matters more than anything else you can control.
Which is better for off-grid solar?
EcoFlow's higher output and expansion battery make it the better foundation if the power station is doing real work in an off-grid setup. If it is a camping and emergency-lighting unit, the Jackery is lighter to move and simpler to live with.

How We Research
Picks are based on manufacturer specifications, current Amazon availability, and patterns across verified owner reviews. Specs, capacities, and included accessories vary by listing — confirm the current details at the retailer before buying.
Note: Keep either unit out of direct summer heat in a vehicle, charge it to full before storing it for a season, and match your solar panel voltage to the station's input range rather than simply adding more panels.
