Jackery vs EcoFlow (2026): Which Power Station?

Jackery and EcoFlow both sell portable power stations on Amazon through their own stores and through Amazon.com, both have moved to LiFePO4 cells, and at each size their stations look alike on paper. They differ on weight, on how they count battery life, on solar panel rules and on how fast they take over when the power goes out. We compare them at three sizes, on the makers' own numbers.

How we chose: we did not test these stations; everything below comes from the Amazon listings, the makers' spec sheets and the CPSC, and each pick was sold by Jackery, EcoFlow or Amazon.com and in stock on September 29, 2026.

Six stations, three sizes

Prices are Amazon's, as of the time shown, and subject to change. Details

Figures are from the listings and the spec sheets for Jackery's Explorer 1000 v2 and EcoFlow's Delta 3 and River 3 Plus. Our portable power stations guide explains watt-hours, chemistry and solar input in more depth.

Weight: Jackery is lighter at every size we could compare

At 1 kWh, the Explorer 1000 v2 weighs 23.8 lb for 1,070 Wh and the Delta 3 weighs 27.6 lb for 1,024 Wh. At the small end, Jackery's 240D is 4.85 lb and EcoFlow's River 3 Plus is 10.4 lb, though the Jackery has no AC outlet. EcoFlow's Delta 3 Max listing gives no weight, so we can't compare at 2 kWh.

For a station that goes in and out of the car on every trip, 4 lb is noticeable. For one that sits in a van or a garage, it is not.

Battery life: same number, different promise

Both brands use LiFePO4 cells now, but they count differently. Jackery rates the Explorer 1000 v2 for 4,000 cycles "to 70%+ capacity"; EcoFlow rates the Delta 3 for 4,000 cycles "to 80+% capacity." EcoFlow's promise is the stronger one: 80% of the original capacity left at the same cycle count.

The small stations flip the picture. Jackery's 240D listing claims at least 70% after 6,000 cycles, and EcoFlow's River 3 Plus gives 3,000 cycles to 80%.

At one charge a weekend, even 3,000 cycles is decades. The rating matters more if you cycle the station daily from solar.

Solar: Jackery's panels, or any panel within EcoFlow's limits

This is the biggest practical difference for overlanders. The Explorer 1000 v2 listing says it "is compatible only with Jackery solar panels for solar charging," and Jackery's spec sheet caps solar input at 400 W. If you already own panels from another brand, that rules the Jackery out or means buying new panels.

EcoFlow gives an input range instead: 500 W for the Delta 3 and 220 W for the River 3 Plus, per their listings. Any panel inside the station's watt and voltage limits will charge it.

Backup at home: switchover time

If the station will also cover a power cut at home, look at the UPS figure. EcoFlow lists under 10 ms for the Delta 3, Delta 3 Max and River 3 Plus. Jackery lists 20 ms for the Explorer 2000 v2, with UL 1778 certification for uninterruptible power systems, but gives no switchover time for the Explorer 1000 v2 on its spec sheet. For a desktop computer or a CPAP, ask the device maker how short a gap it tolerates.

Cold weather

Jackery's Explorer 1000 v2 spec sheet gives a charging range of 32 to 113°F and a discharge range of 14 to 113°F. EcoFlow's River 3 Plus spec sheet gives the same, and 68 to 86°F as the best range for use and storage. EcoFlow's Delta 3 page gives no range. The Jackery 240D listing says it operates from -4°F.

At either brand, charge in the warm car on a frosty morning.

Warranty and recalls

Jackery's spec sheet lists a warranty of "3+2 Years" for the Explorer 1000 v2, and EcoFlow lists 5 years for the Delta 3. Read each maker's terms for what the extra years require.

On recalls, the record is lopsided. The CPSC's Delta Max 2000 notice covers about 25,030 EcoFlow units, model EFD310, sold from July 2022 to May 2025, after six reported fires; the remedy is a free firmware update. If you are buying a used EcoFlow, check the nameplate for EFD310. We found no CPSC recall of a Jackery power station on September 29, 2026. The recall covers model EFD310 only.

Who each brand suits

• Buy Jackery if the station travels every trip and weight matters, if you are starting from scratch with Jackery panels, or if all your gear charges by USB-C (the 240D).
• Buy EcoFlow if the station doubles as home backup, if you already own panels from another brand, if you want the 80% cycle rating and 5-year warranty, or if you need AC in a small station (the River 3 Plus).
• At 2 kWh, pick the EcoFlow Delta 3 Max for high-draw appliances and the faster UPS, and the Jackery Explorer 2000 v2 if its stated 39.5 lb matters.

Frequently Asked Questions

Can I connect a Jackery and an EcoFlow together?

Not as one system; neither maker lists the other's batteries as compatible. EcoFlow lists Delta 2, Delta 2 Max, Delta Pro 3 and Delta 3 extra batteries as compatible with the Delta 3.

Which one is quieter?

Both say about 30 dB in their quiet modes: Jackery for the Explorer 1000 v2's overnight charging mode, EcoFlow for the Delta 3 under 600 W and the River 3 Plus.

Is the Jackery 240D a power station or a power bank?

Jackery calls it a "power bank station." It has 256 Wh and no AC inverter, so it runs anything that charges by USB-C or USB-A, but not a device with a wall plug.
