The short answer

On published specs, Jackery is the cheaper line per watt-hour (a median of $0.57 across the 21 Jackery models we track prices for, against $0.71 across 19 EcoFlow models) and lists the higher cycle counts (4,000 to 6,000 on the LiFePO4 models compared here, against 3,000 to 4,000 for EcoFlow, though Jackery’s stated end point is 70% of capacity and EcoFlow’s 80%). EcoFlow lists more AC output (median 2,300 W against 1,850 W), though the two tie from about 3 to 3.6 kWh, where Jackery’s HomePower 3000 and 3600 Plus list 3,600 W continuous and 7,200 W surge, the same as EcoFlow’s DELTA 3 Ultra. Warranties are close: most EcoFlow models we have a warranty term for carry 5 years, and Jackery gives its current v2, Plus and HomePower models 3 years plus 2 more (5 in total) when bought from Jackery or registered. Buy Jackery for the lowest cost per Wh from 700 Wh upward, or for one box that reaches 5,040 Wh. Buy EcoFlow for 3,000 W from a 2,048 Wh unit (the DELTA 3 Max Plus), 4,000 W from the 4,096 Wh DELTA Pro 3, or the largest expandable system from either brand: EcoFlow lists the DELTA Pro Ultra at 7,200 W per inverter with about 6 kWh battery packs, expandable to 90 kWh, against about 60 kWh for Jackery’s 5000 Plus with add-on packs.

Every figure here comes from the makers’ published specifications, not from using the units.

The two line-ups in numbers

Each median in the table covers the models we have that figure for.

Size-by-size match-ups

Each table sets the closest-capacity EcoFlow and Jackery models side by side, with a second EcoFlow model where a sibling is a near match. A warranty of 3+2 means 3 years plus 2 more: Jackery adds the 2 when the unit is bought from Jackery or registered, EcoFlow when it is registered in the EcoFlow app. W per Wh is AC output divided by capacity; Wh per lb is capacity divided by weight.

Small: under 700 Wh

The 250 to 300 Wh pair is close: the RIVER 2 and Explorer 300 Plus both list 300 W, and Jackery stores slightly more per pound (34.7 Wh per lb against 33.2). EcoFlow’s RIVER 3 Plus is the nearer capacity match (286 Wh against 288 Wh) and lists 600 W, about 2.1 W per Wh against 1.04, though at 10.4 lb it is the heaviest of the three; it also takes an add-on battery. EcoFlow lists 600 W of surge, 3,000 cycles and 110 W of solar input for the RIVER 2 (spec page) and 1,200 W of surge, 3,000 cycles and 220 W of solar input for the RIVER 3 Plus (spec page), both checked October 2026, with 5-year terms under its warranty policy.

Jackery’s US store now sends its Explorer 300 Plus page to the Explorer 300 v2, which Jackery lists at 288 Wh of LiFePO4, 300 W (600 W surge peak), 4,000 cycles to 70% capacity, 8.16 lb and 3 years plus 2, for $299 (maker list price, October 2026). It showed as sold out in mid-October 2026, and the sold-out notice links to the original Explorer 300, an older lithium-ion unit with 293 Wh and 300 W (500 W surge) that Jackery rates at 800 cycles to 80% capacity, with 2 years plus 1 of warranty, for $289 (maker list price, October 2026). Its cycle rating is a fifth of the 300 v2’s for $10 less, so check which 300 you are buying. Jackery no longer lists the Explorer 500 in the US; its old page forwards to the HomePower 1000 v2, and the 640 Wh Explorer 600 v2 (LiFePO4, 500 W, 1,000 W surge) also showed as sold out.

Across the six small EcoFlow models and five Jackery models we track prices for, EcoFlow’s median is $0.86 per Wh against $1.04 for Jackery. See River 2 vs River 3 and Jackery 300 vs 300 Plus.

Mid: 700 to 1,600 Wh

EcoFlow has three models in this bracket against six for Jackery: the Classic, the DELTA 3 Plus (also 1,024 Wh, with 1,800 W, 4,000 cycles to 80% capacity, a 5-year term and add-on battery support) and the original DELTA at 1,260 Wh. EcoFlow lists 3,600 W of surge, 1,000 W of solar input, 1,500 W of AC charging and 27.6 lb for the DELTA 3 Plus (spec page checked October 2026), and gives no cycle count for the Classic, only an estimated 10-year battery life (spec page). Both 1,024 Wh models list 1,800 W of rated output and 3,600 W of surge; the larger figures on their pages, 2,200 W for the Plus and 2,600 W for the Classic, are X-Boost figures, the largest appliance EcoFlow says each can run in that mode, not rated output. Jackery lists a 3,000 W surge and 400 W of solar input for the Explorer 1000 v2 (spec page checked October 2026). The Classic’s 1,400 W AC charging would refill 1,024 Wh in about 44 minutes at the full rate (1,024 / 1,400 = 0.73 h; real charging slows near full). Jackery’s HomePower 1000 v2 matches its 1,024 Wh and lists 6,000 cycles. Median cost per Wh is $0.54 across Jackery’s six and $0.75 across EcoFlow’s three, all three of them “Solar Generator” bundle prices.

Jackery’s two 1,536 Wh units sit at the top of this bracket. The Explorer 1500 Ultra lists 1,800 W continuous, the same as the DELTA 3 Classic, with a 3,600 W peak for 5 seconds and 2,000 W for up to 15 minutes; it adds an IP65 rating, 800 W of solar input, 4,000 cycles to 70% capacity, about 38.6 lb and 3 years plus 2, for $1,199 (maker list price, October 2026). The Explorer 1500 v2 lists more continuous output, 2,000 W with a 4,000 W surge, plus 6,000 cycles and 31.97 lb, for $949 (maker list price, October 2026). See Delta 3 vs Delta 3 Classic and Jackery 1000 v2 vs 1000 Plus.

Large: 1,600 to 3,000 Wh

Same capacity, and 2,400 W against 2,200 W; both carry 5 years as 3 plus 2, Jackery’s when bought direct or registered and EcoFlow’s on app registration. Jackery lists 4,000 cycles and 400 W of solar input for the 2000 v2 (spec page checked October 2026), while EcoFlow gives an estimated 10-year life for the DELTA 3 Max rather than a cycle count and lists 2,400 W continuous, 4,800 W of surge and 500 W of solar input for it (product page, checked October 2026). The 3,000 W 2 kWh EcoFlow is the DELTA 3 Max Plus: the same 2,048 Wh with 3,000 W continuous, 6,000 W of surge, 1,000 W of solar input, about 48.7 lb and the same 3-plus-2 term (spec page), so check which model you are buying. The 3,400 W (Max) and 3,800 W (Max Plus) figures EcoFlow also quotes are X-Boost figures, not rated output. Jackery’s six models in this bracket include the HomePower 2000 Plus v2 (2,048 Wh, 2,400 W, 6,000 cycles), and their median of $0.44 per Wh is the lowest of any bracket for either brand, against $0.71 for EcoFlow’s three.

Home backup: over 3,000 Wh

The DELTA 3 Ultra and HomePower 3000 tie on output at 3,600 W continuous and 7,200 W surge. The HomePower 3000 takes more solar input (1,000 W against 800 W) and weighs less (59.5 lb against 72.1 lb); EcoFlow lists 32.7 kg for the DELTA 3 Ultra and gives an estimated 10-year life rather than a cycle count (spec page), and Jackery lists 4,000 cycles and 1,000 W of solar input for the HomePower 3000 (spec page), both checked October 2026. The next pair ties on output too: DELTA Pro (3,600 Wh, 3,600 W, 5 years) against HomePower 3600 Plus (3,584 Wh, 3,600 W, 6,000 cycles, 3 years plus 2 when bought direct or registered, 77.2 lb). Above 3,600 Wh the field narrows. The Jackery Solar Generator 5000 PlusCheck price on Amazon↗ lists 5,040 Wh, 7,200 W, 4,000 cycles, 5 years and 134.5 lb. EcoFlow’s DELTA Pro 3 lists 4,096 Wh, 4,000 W, 4,000 cycles and 2,600 W of solar input, takes add-on batteries, and carries 5 years under EcoFlow’s warranty policy (checked October 2026). EcoFlow’s biggest system is the DELTA Pro Ultra, which EcoFlow lists at 7,200 W per inverter with about 6 kWh per battery pack, expandable to 90 kWh across several inverters and packs. EcoFlow’s other products above 3,600 Wh are not comparable power stations: one is a fuel-burning generator and two are 5,000 Wh LFP batteries.

Leaving those two batteries out, the median is $0.53 per Wh across four Jackery models against $0.63 across five EcoFlow models.

Where each brand wins, and where it loses

EcoFlow

• Wins on output from 1 to 2 kWh. More AC watts in two of the four pairs: 1,800 against 1,500 W and 2,400 against 2,200 W, or 3,000 W from the DELTA 3 Max Plus. The small RIVER 2 pair ties at 300 W, though the RIVER 3 Plus lists 600 W from 286 Wh, and the 3 kWh pair ties at 3,600 W.
• Ties on warranty. 8 of the 10 EcoFlow models we have a warranty term for carry 5 years, and EcoFlow’s warranty policy sets the DELTA 3 Classic, DELTA 3 Max, DELTA 3 Max Plus and DELTA 3 Ultra at 3 years plus 2 on registration, the same structure as Jackery’s (checked October 2026). Most Jackery models carry 3 years as standard, but Jackery adds 2 years on its current v2, Plus and HomePower models when bought from Jackery or registered, and the Solar Generator 5000 Plus carries 5.
• Wins on small units. Median $0.86 per Wh against $1.04 under 700 Wh.
• Loses on cost from 1,000 Wh up. A median of $0.67 per Wh across 11 EcoFlow models (battery-only products left out) against $0.52 across 16 Jackery models.
• Loses on weight per Wh. Less energy per pound in each pair: 33.2 against 34.7, 38.4 against 45.0 and 45.7 against 51.7 Wh per lb, and at 3,072 Wh the DELTA 3 Ultra weighs 72.1 lb against 59.5 lb for the HomePower 3000.
• Fewer published cycle ratings. EcoFlow quotes an estimated 10-year battery life rather than a cycle count for the DELTA 3 Classic, DELTA 3 Max, DELTA 3 Max Plus and DELTA 3 Ultra, so cycle life is harder to compare than with Jackery.

Jackery

• Wins on cost from 700 Wh up. Medians of $0.54 (mid), $0.44 (large) and $0.53 (over 3,000 Wh).
• Wins on rated cycles. 14 of the 16 Jackery models with a rating list 4,000 or 6,000; the other two are 800-cycle Li-ion units.
• Wins on single-box size. 5,040 Wh at 7,200 W in one unit, against 4,096 Wh at 4,000 W for EcoFlow’s DELTA Pro 3. EcoFlow’s DELTA Pro Ultra goes bigger (7,200 W per inverter, 6 kWh battery packs) but stacks an inverter on separate battery modules.
• Loses on output from 1 to 2 kWh. 1,500 W against 1,800 W and 2,200 W against 2,400 W (3,000 W for the DELTA 3 Max Plus) in those pairs, and a median of 1,850 W. Around 3 kWh it ties at 3,600 W.
• Still sells an older lithium-ion model. The original Explorer 300 is rated 800 cycles to 80% capacity, against 4,000 or more for the Jackery LiFePO4 models compared here. Every model in the size tables, from either brand, uses LiFePO4.

Charging speed is the claim people repeat most, and the published figures cannot settle it, because the two makers state it differently. EcoFlow gives AC charging power: 1,400 W for the DELTA 3 Classic, 1,500 W for the DELTA 3 Plus and 1,800 W for the DELTA 3 Max and DELTA 3 Ultra. Jackery gives AC charge times instead, among them 1.75 hours for 2,042 Wh (2000 v2), 2.5 hours for 3,584 Wh (HomePower 3600 Plus) and 3.5 hours for 5,040 Wh (5000 Plus). Capacity divided by time gives about 1,170 W, 1,430 W and 1,440 W, an average over the whole charge, while EcoFlow’s figures are peak input and charging slows near full, so the two cannot be compared directly and neither brand is a clear winner.

Connecting to your home panel

Running house circuits, rather than plugging appliances into the unit, takes switch hardware between the battery and your breaker panel. CPSC warns never to power house wiring by plugging a generator into a wall outlet, which it calls backfeeding, because it puts utility workers and neighbors on the same transformer at risk of electrocution (CPSC safety alert). Both brands sell their own hardware for the job, and both route installation through an electrician.

EcoFlow lists the Smart Home Panel 2 as expandable to 90 kWh with 21.6 kW of output, and it can also take a 3 to 12 kW portable gas generator. Jackery’s Smart Transfer Switch is not waterproof and goes indoors or somewhere sheltered from rain. Neither compatibility list includes the units in the 3 kWh match-up. Jackery says the HomePower 3000 can keep up to six essential circuits running through a manual transfer switch and sells a 120 V, 30 A switch as an add-on on that unit’s page for $399; it lists that 120 V switch for the 2000 Plus and 3600 Plus too, and a 240 V, 50 A switch for the 5000 Plus, or two 3600 Plus units through a parallel combiner, at $550 (maker list prices, October 2026). EcoFlow names a manual transfer switch or an inlet box as the two ways to connect the DELTA 3 Ultra to a home, and sells it in a bundle with a 125 V, 30 A transfer switch, which showed as sold out in mid-October 2026. See manual transfer switches for how they work.

Who should buy which

• Phones, a laptop and a CPAP: either brand under 700 Wh, with EcoFlow cheaper per Wh there. A CPAP uses about 320 Wh a night from an AC outlet with the humidifier off (240 Wh on a DC cable) and 640 Wh with it on, so a 256 to 288 Wh unit covers at most one humidifier-off night, run from DC; see CPAP watts and runtimes.
• A fridge through an outage: a modern full-size fridge uses about 1,000 to 2,000 Wh a day, so aim at 2,000 Wh or more. Both brands clear a fridge’s startup surge, so cost per Wh decides, which favors Jackery (fridge power draw).
• Solar panels on a van or cabin: EcoFlow lists 500 to 1,000 W of solar input for its 1 to 2 kWh DELTA units and 1,600 to 5,600 W for its large ones (DELTA Pro, DELTA Pro 3, DELTA Pro Ultra); Jackery lists 400 W for the Explorer 1000 v2 and 2000 v2 and 1,000 W for the HomePower 3000, so EcoFlow accepts more solar at 1 to 2 kWh. Panel sizing is in how to size a solar system, and sizing the unit itself in what size power station.
• 3,000 W or more at once, from 2,000 to 4,096 Wh: EcoFlow at 2,048 Wh (3,000 W from the DELTA 3 Max Plus) and 4,096 Wh (4,000 W); from 3,072 to 3,600 Wh the brands tie at 3,600 W (DELTA 3 Ultra and DELTA Pro against HomePower 3000 and 3600 Plus). A single box above 4,096 Wh: Jackery’s 5,040 Wh at 7,200 W. The largest expandable system: EcoFlow’s DELTA Pro Ultra, 7,200 W per inverter with about 6 kWh battery packs and up to 90 kWh. For circuits and transfer switches see home battery backup and manual transfer switches.
• Lowest cost per Wh overall: neither line. BLUETTI’s median is $0.515, below both, and ALLPOWERS, OUPES and Pecron sit at $0.37 to $0.38; see Bluetti vs EcoFlow and Bluetti vs Jackery.

Frequently asked questions

Is EcoFlow or Jackery better for home backup?

It depends on the biggest load and how much you want in one box. At about 3 kWh the two tie: EcoFlow’s DELTA 3 Ultra and Jackery’s HomePower 3000 (both 3,072 Wh) list 3,600 W continuous and 7,200 W surge. EcoFlow lists more at 2,048 Wh (3,000 W from the DELTA 3 Max Plus) and at 4,096 Wh (4,000 W from the DELTA Pro 3). Above 4,096 Wh, Jackery’s 5000 Plus (5,040 Wh, 7,200 W) is the largest single unit, while EcoFlow’s DELTA Pro Ultra (7,200 W per inverter, about 6 kWh battery packs, expandable to 90 kWh) is the larger expandable system; the 5000 Plus reaches about 60 kWh with add-on packs.

Which brand’s batteries last longer?

Jackery lists the higher counts: 4,000 cycles to 70% of original capacity for the Explorer 1000 v2, 2000 v2 and 1500 Ultra and the HomePower 3000, and 6,000 for the HomePower 3600 Plus. EcoFlow lists 3,000 for the RIVER 2 and RIVER 3 Plus, 3,500 for the DELTA Pro and DELTA Pro Ultra and 4,000 for the DELTA 3 Plus and DELTA Pro 3, all to 80%, and a 10-year life estimate instead of a count for the DELTA 3 Classic, Max, Max Plus and Ultra. Warranties are similar: 5 years on most EcoFlow models we have a term for, and 3 years plus 2 on current Jackery models bought direct or registered. For occasional use neither binds: one full cycle a week is 52 a year, so 3,000 cycles lasts about 58 years. At a daily cycle, 3,000 cycles is 8.2 years and 4,000 is 11. These are maker ratings, not evidence of lifespan in use.

Can I add capacity later?

We have confirmed that 9 EcoFlow models and 5 Jackery models here take add-on batteries (the Jackery ones are the 2000 Plus, HomePower 2000 Plus v2, Explorer 2000 Plus, HomePower 3600 Plus and 5000 Plus), and we track current expansion batteries for both brands: 6 for EcoFlow and 4 for Jackery, the Jackery ones built for the 2000 Plus, 3600 Plus and 5000 Plus lines. Confirm a pack fits your exact model before buying.
