Jackery vs EcoFlow

1. The Short Verdict

Jackery and EcoFlow are the two names most people shortlist, and at a glance their catalogues look interchangeable: a 1 kWh box, a 2 kWh box, an expandable home-backup unit and a large 120/240V system. Line the current models up spec for spec, though, and a consistent pattern appears. EcoFlow puts more inverter, more charging power and more solar input into each size class. Jackery builds lighter units and keeps the interface simpler.

At 1 kWh, the EcoFlow DELTA 3 Plus gives you 1800W of continuous AC output against 1500W on the Jackery Explorer 1000 v2, takes 1000W of solar against 400W, and expands to 5 kWh where the Explorer does not expand at all. The Explorer, in turn, is nearly four pounds lighter and slightly bigger in capacity. At 2 kWh and at the whole-home end, the same pattern repeats with one notable exception: Jackery's Explorer 5000 Plus out-muscles EcoFlow's DELTA Pro 3 on output and solar, at the cost of more than 20 extra pounds.

That is why our best portable power station guide names an EcoFlow as the best overall pick and a Jackery as the best value and first-time buy. The EcoFlow DELTA 2 that leads that guide has now been succeeded on EcoFlow's US store by the DELTA 3 family, which carries the same 1024 Wh capacity with a faster charger and a longer cycle rating, so everything that made the DELTA 2 our top pick applies to its successor.

The rest of this page goes size by size using the makers' own published specifications, then through the categories that matter after purchase: cycle ratings, wall and solar charging, UPS switchover, app and noise, and warranty. If you have not yet worked out how much capacity you need, do that first with our guide to what size portable power station you need, because picking the right size matters more than picking the right brand.

2. 1 kWh: Jackery Explorer 1000 v2 vs EcoFlow DELTA 3 Plus

This is the size most people buy: enough to keep a fridge, a router and some lights going through an evening outage, or to run a campsite for a weekend. Jackery's entry is the Explorer 1000 v2. EcoFlow's is the DELTA 3 family, of which the DELTA 3 Plus is the version to compare, since it adds a second solar input and a faster 140W USB-C port over the plain DELTA 3 for a modest premium.

On paper the DELTA 3 Plus wins most rows. Its 1800W inverter runs a 1500W space heater or a full-size microwave with headroom to spare, where the Explorer's 1500W limit makes those borderline. Its six AC outlets against three matter more than they sound during an outage, when you are otherwise daisy-chaining a power strip. And its 1000W solar ceiling means two or three mid-size panels can refill it in an afternoon, where the Explorer tops out at two 200W panels.

The Explorer's advantages are real but narrower. It is 3.8 pounds lighter, which you notice carrying it to a campsite or up from a basement. It holds 46 Wh more energy. And its spec sheet is simpler: three outlets, one charging mode switch in the app, nothing to configure. For someone buying their first power station mainly for camping and the occasional outage, that simplicity has value, and it is why the Explorer 1000 v2 is the value pick in our roundup.

If you think you might want more capacity later, Jackery's answer at this size is the newer HomePower 1000 Plus v2, a 1024 Wh unit with 1800W of output, 3600W peak, a sub-10 ms UPS switchover and expansion to 11 kWh using 2 kWh battery packs. That makes it a direct rival to the DELTA 3 Plus on paper, and the choice between them comes down to price on the day and whose battery ecosystem you would rather buy into.

Our verdict at this size: the DELTA 3 Plus is the more capable machine and the better choice for home backup. The Explorer 1000 v2 is the better choice if weight and simplicity top your list and you are confident 1 kWh and 1500W are all you will ever need.

3. 2 kWh: Explorer 2000 v2 and HomePower 2000 Plus v2 vs DELTA 3 Max

At 2 kWh both brands split their lineup in two: a fixed-capacity unit and an expandable one. Jackery's fixed unit is the Explorer 2000 v2; its expandable model is the HomePower 2000 Plus v2, which replaces the Explorer 2000 Plus that many older comparisons still reference. EcoFlow's equivalents are the DELTA 3 Max and the expandable DELTA 3 Max Plus, with the older DELTA 2 Max still on sale alongside them.

Fixed capacity: Explorer 2000 v2 vs DELTA 3 Max

This is the closest pairing in either lineup. The Jackery is about five pounds lighter and the EcoFlow has a bit more output, one more outlet and slightly more solar headroom. Neither is sold as expandable. If you want a 2 kWh unit that you will carry between a house and a cabin or an RV, the Explorer 2000 v2's weight advantage is a reasonable tiebreaker. If it will sit in a utility room as backup, the DELTA 3 Max's output and quicker UPS switchover are worth more.

Expandable: HomePower 2000 Plus v2 vs DELTA 3 Max Plus

Here the EcoFlow's 3000W inverter is the headline. That is enough to start most well pumps, run a window air conditioner and a fridge together, or run a full-size microwave with other loads on, where 2400W gets tight. The Jackery counters with a battery rated for 6,000-plus cycles and a weight Jackery says is 34 percent lower than the 61.5-pound Explorer 2000 Plus it replaces, which makes it genuinely movable by one person. Its Priority Routing feature, which sheds non-essential outlets at a battery threshold you set, is a thoughtful touch for outages.

The older DELTA 2 Max is worth a look if you find it discounted: 2400W, 1000W of solar input, 3,000 cycles to 80 percent and expansion with up to two extra batteries, at 50 pounds. It is heavier and has a lower cycle rating than either newer unit, but the core specification is still competitive.

4. Whole Home: Jackery Explorer 5000 Plus vs EcoFlow DELTA Pro 3

At the top end both brands sell 120/240V systems meant to power well pumps, central air handlers and sub-panels through a transfer switch. This is the one size class where Jackery out-specs EcoFlow on raw output, and the trade-off is weight.

The Explorer 5000 Plus is the bigger machine: 23 percent more capacity, 7200W of continuous output and high-voltage solar input that Jackery says fully recharges it in 1.7 hours with enough panels. That much output runs a 240V well pump and central air handler together in a way the DELTA Pro 3's 4000W cannot. Jackery also lists an online UPS mode with zero switchover, which suits anything that cannot tolerate even a brief interruption.

The DELTA Pro 3 is the more practical unit to live with. It is 21 pounds lighter, charges to 80 percent from the wall in 50 minutes against three and a half hours for the Jackery, and EcoFlow's Smart Home Panel 2 and Smart Generator integrations are more mature. If your home backup plan leans on a wall outlet or a generator to recharge between outages, that charging speed matters more than the extra kilowatt-hour.

At this level the system matters more than the box. Budget for a transfer switch or smart panel installed by an electrician; our guide to transfer switch types and installation explains what each option involves. And compare full kits, including panels, because both brands sell these units mostly as bundles, which is where a lot of the real price difference sits.

5. Battery Chemistry, Cycle Ratings and Warranty

Every current Jackery and EcoFlow model in this comparison uses LiFePO4, lithium iron phosphate, cells. That is a meaningful change from a few years ago, when Jackery's original Explorer line used NMC lithium-ion rated for roughly 500 cycles. LiFePO4 trades a little energy density for far longer cycle life and better thermal stability, and our explainer on LiFePO4 vs lithium-ion power stations covers why that trade is worth making for anything you plan to keep.

The cycle numbers themselves need reading carefully, because the two brands rate to different end points. Jackery typically quotes cycles to 70 percent of original capacity: 4,000 cycles to 70 percent on the Explorer 1000 v2, 2000 v2 and 5000 Plus. EcoFlow quotes cycles to 80 percent: 4,000 cycles to 80 percent on the DELTA 3, DELTA 3 Plus and DELTA Pro 3. Reaching 80 percent is a stricter standard than reaching 70 percent, so a 4,000-cycle EcoFlow rating is, on its face, the stronger claim of the two.

Jackery's newer HomePower v2 line moves the goalposts the other way, with 6,000-plus cycles quoted for the HomePower 2000 Plus v2. In practice, all of these ratings are far beyond what most owners use. Even daily full cycling, which almost no backup or camping owner does, would take more than ten years to reach 4,000 cycles. For a typical owner the battery will outlast the electronics around it, and the cycle figure is a tiebreaker, not a deciding factor.

Warranty is where the fine print matters more. Jackery lists most current models as 3 plus 2 years, meaning a three-year standard warranty with two extra years when you buy from Jackery directly or an authorised seller. EcoFlow lists five years on its current DELTA models, which on several product pages is described as a three-year standard warranty plus two years on registration in the EcoFlow app. Either way, register the unit the day it arrives and keep the receipt, because the extended years are not automatic.

6. Wall Charging Speed and Solar Input

Charging speed is EcoFlow's strongest category. Its X-Stream charging pulls 1500W from a wall outlet on the DELTA 3 Plus, refilling it in 56 minutes, and 1800W on the 2 kWh DELTA 3 Max models, reaching 80 percent in 64 to 68 minutes. Jackery's standard charging is slower, 1.58 hours on the Explorer 1000 v2 and 1.75 hours on the Explorer 2000 v2, though both have an emergency fast-charge mode, switched on in the app, that brings the 1000 v2 down to about an hour and the 2000 v2 to about 1.3 hours.

Why that matters: if a storm is forecast and your unit is at 30 percent, you can top up an EcoFlow in the gap between the warning and the outage. In a long outage with a generator, faster charging also means less generator run time per refill. For camping or occasional use, where the unit sits on a charger overnight, the difference is close to irrelevant.

Solar input is the bigger practical gap. At 1 kWh, EcoFlow accepts 1000W of solar across two inputs against 400W on the Explorer 1000 v2. At 2 kWh, the DELTA 3 Max Plus takes 1000W against 800W on the HomePower 2000 Plus v2, and the non-expandable models take 500W and 400W respectively. If you plan to run off solar for days at a time, that ceiling decides how many panels you can usefully connect and how fast a short sunny window refills the battery.

Both brands use their own connectors on their panels but accept standard panels within their voltage windows, which run roughly 11 to 60 volts on the smaller units. Our best portable solar panels guide covers matching panels to these inputs, and if you would rather buy a matched kit, our best solar generator roundup compares the bundles directly. Remember that a panel's rated wattage is a lab figure; in real sun expect roughly 60 to 80 percent of it.

7. UPS Switchover, App and Noise

Both brands sell their units as uninterruptible power supplies, meaning devices stay plugged into the station, the station stays plugged into the wall, and it takes over when the grid drops. The figure to compare is switchover time. EcoFlow lists under 10 ms across the DELTA 3 family and 10 ms on the DELTA Pro 3. Jackery lists under 20 ms on the Explorer 1000 v2 and the Explorer 5000 Plus in backup mode, under 10 ms on the HomePower 1000 Plus v2, and 0 ms in the 5000 Plus's online mode.

Most desktop computers and network gear ride through 20 ms without noticing, but some sensitive equipment, older desktop power supplies and some aquarium or medical controllers can reset on a longer gap. If the reason you are buying is to keep a desktop PC or a home server running through flickers, the faster switchover is worth paying attention to, and the EcoFlow DELTA 3 models or Jackery's newer HomePower v2 units are the safer bets.

Both apps connect over Wi-Fi and Bluetooth and let you monitor input and output, toggle outlets, and set charge limits. EcoFlow's app is the more ambitious of the two, with time-of-use charging and a storm warning mode that charges the unit automatically when severe weather is forecast. Jackery's app is simpler and gates its emergency fast charge mode, which is worth knowing because you need the app to get the advertised charge times.

On noise, both brands now quote very quiet figures under light loads: EcoFlow under 30 dB at up to 600W on the DELTA 3 and 25 dB at 600W on the DELTA 3 Max models, and Jackery 30 dB in its quiet mode. Under heavy load or fast charging, the cooling fans on any of these units become clearly audible, so if it will live in a bedroom, plan to charge it during the day.

8. Who Should Buy Which

Buy EcoFlow if your priority is home backup. Its higher inverter output at every size below the whole-home class, its faster wall charging, its larger solar input and its sub-10 ms UPS switchover all point the same way: it is the better machine for keeping a house running. The DELTA 3 Plus is the sweet spot for most households, and the DELTA 3 Max Plus is the one to choose if you need to start a well pump or run a window air conditioner alongside a fridge.

Buy Jackery if you value low weight and simplicity, particularly for camping, RV use or a first power station that someone else in the household also needs to operate. The Explorer 1000 v2, which Jackery bills as the smallest and lightest 1 kWh LiFePO4 unit on the market, has the simplest controls here, and the HomePower 2000 Plus v2 makes a 2 kWh expandable system that one person can actually carry. At the very top end, the Explorer 5000 Plus is the pick if you need 7200W of 240V output and do not need to move it.

If you are torn, decide by the one number that matters most to you. Need more than 1500W from a 1 kWh unit? EcoFlow. Need it under 25 pounds? Jackery. Need to refill quickly from the wall before a storm? EcoFlow. Need the most raw 240V output for the money? Jackery's 5000 Plus. Most buyers find one of those questions settles it.

Whichever brand you lean toward, check how the unit compares to the other LiFePO4 options from Bluetti and Anker before you buy.
