EcoFlow vs Jackery: how do their power stations compare?

"EcoFlow vs Jackery" is really a question about models. Both brands sell small, medium and huge power stations. So the fair way to compare is size class by size class.

We compared these from the makers' published specs; we haven't tested them. Every number below comes from EcoFlow's or Jackery's own product page, checked on October 1, 2026.

Home-backup class: DELTA Pro 3 vs Explorer 5000 Plus

These two are the closest like-for-like pair in our list. Both are big, wheeled, 120/240 V units meant to back up part of a house.

Spec	EcoFlow DELTA Pro 3	Jackery Explorer 5000 Plus
Battery	4,096 Wh	5,040 Wh
AC output (continuous)	4,000 W	7,200 W
Surge	8,000 W	14,400 W
240 V outlet	Yes (L14-30R and 6-20R)	Yes (L14-30R / 14-50R)
Other AC outlets	4 × 5-20R, 1 × TT-30R	4 × 5-20R
Max solar input	2,600 W	Up to 4,000 W (maker's figure)
Battery type	LFP (LiFePO4)	LiFePO4
Cycle rating	4,000 cycles to 80%	4,000 cycles to 70%+
UPS switchover	10 ms	Under 20 ms backup; 0 ms online
Expandable to	Up to 48 kWh (system)	Up to 60 kWh
Warranty	3 years + 2 more on app registration	5 years, when bought from Jackery.com
Weight	See maker page	About 134.5 lb

What stands out: The Jackery has a bigger battery and much more output. The EcoFlow adds a TT-30R RV outlet and a 240 V 6-20R outlet. Both makers rate 4,000 cycles, but not to the same line. EcoFlow says 80% of capacity remains; Jackery says 70% or more. That's a different yardstick, so the two numbers aren't directly comparable.

Either one connects to a house only through a transfer switch or interlock installed by a licensed electrician. Never plug one into a wall outlet to "backfeed" the house.

Mid-size: DELTA 3 Max Plus vs Explorer 1000 v2 (not a like-for-like pair)

These are the mid-size models from each brand on our list. They are not the same size, so don't read this table as a head-to-head. The EcoFlow has about twice the battery and twice the output.

Spec	EcoFlow DELTA 3 Max Plus	Jackery Explorer 1000 v2
Battery	2,048 Wh	1,070 Wh
AC output (continuous)	3,000 W	1,500 W
Surge	6,000 W	3,000 W
Max solar input	1,000 W	400 W
Battery type	LFP (LiFePO4)	LiFePO4
Expansion	2 to 10 kWh with extra batteries	No expansion port listed in the tech specs
Weight	About 50 lb (listed as 22.1 + 0.4 kg)	About 23.8 lb
Warranty	3 years + 2 more on app registration	3 + 2 years at Jackery.com

If you're choosing at the 1 kWh size, compare the Explorer 1000 v2 with other 1 kWh stations instead. Our Jackery 1000 v2 vs Anker C1000 vs BLUETTI Elite 100 V2 page does that.

Small: the RIVER 2 Max 500

EcoFlow's RIVER 2 Max 500 lists 499 Wh, 500 W (1,000 W surge), 220 W of solar input and 13.2 lb. We don't list a Jackery of the same size, so there's no fair pair here. At 500 W, it suits phones, laptops, lights, a Wi-Fi router or a CPAP, not a fridge's start-up surge on most models.

General differences between the brands

These come from the makers' own pages. They can change, so check before you buy.

• Warranty wording. EcoFlow's pages list a 3-year standard warranty, plus 2 more years if you register the unit in the EcoFlow app. Jackery's pages list "3 + 2 years" on the Explorer 1000 v2 and 5 years on the 5000 Plus, and say the full length applies when you buy from Jackery.com.
• Cycle ratings. EcoFlow rates to 80% of capacity. Jackery rates to 70% or more. When a spec sheet says "4,000 cycles," check which line it means.
• Expandability. Both brands sell expandable home-backup units. On our list, EcoFlow's mid-size DELTA 3 Max Plus is expandable; Jackery's Explorer 1000 v2 lists no expansion port.
• Solar input. Among the models here, EcoFlow lists more solar input at the mid size (1,000 W vs 400 W). At the top end, Jackery lists more (up to 4,000 W vs 2,600 W).

How to compare any EcoFlow and Jackery pair

1. Start with Wh. It tells you how long things run. Hours ≈ Wh × 0.85 ÷ watts in use.
2. Check continuous watts. They must be above everything you'll run at once.
3. Check surge watts. They must be above your biggest motor's starting watts, like a fridge or a sump pump.
4. Check the outlets. Need 240 V or a 30 A RV plug? Only some models have them.
5. Check charging. See how long it takes to charge a power station.

Who each suits

• DELTA Pro 3: someone who wants 240 V home backup with an RV (TT-30R) outlet on the same unit, and 10 ms UPS switchover.
• Explorer 5000 Plus: someone who wants the most battery and output in one box from this list, and can move a 134.5 lb unit on its wheels.
• DELTA 3 Max Plus: someone who wants about 2 kWh and 3,000 W on 120 V, with room to add batteries later.
• Explorer 1000 v2: someone who wants about 1 kWh in a unit under 24 lb, for a fridge for part of a day, a CPAP or camping.
• RIVER 2 Max 500: someone who needs light, small loads covered, like phones, lights, a router or a CPAP.
