Jackery vs EcoFlow: which power station brand for a UK home?

How the two ranges line up

Jackery and EcoFlow both sell units at the two sizes that matter most in a power cut. At about 1kWh, Jackery’s Explorer 1000 v2 (1,070Wh, 1,500W) sits against EcoFlow’s DELTA 3 Plus (1,024Wh, 1,800W). At about 2kWh, the Explorer 2000 v2 (2,042Wh, 2,200W) sits against the DELTA 3 Max Plus (2,048Wh, 3,000W). All four use lithium iron phosphate cells and have a 12V car socket, by their makers’ spec tables, and three of the four quote a UPS switchover time for running a router or fridge through the unit.

One naming point matters before anything else. Jackery’s plain “v2” units are fixed-capacity: its own comparison pages list the 1000 v2 as “non-expandable” and the 2000 v2 as “not supported” for extra batteries. Jackery also sells an Explorer 1000 Plus v2 and 2000 Plus v2 that do take extra batteries and are closer rivals to EcoFlow’s “Plus” units; they are not in our catalogue, so this guide compares the units we track and says where the Plus v2 siblings change the answer.

If you haven’t settled on a size, start with what size power station do I need, and if you are weighing a battery against a petrol generator, read power station vs generator first. Store stock changes often; the cards on this page show live prices and availability.

About 1kWh: Explorer 1000 v2 vs DELTA 3 Plus

The capacities are near enough equal, 1,070Wh against 1,024Wh, and both makers rate the pack at 4,000 cycles, though to different end points: Jackery to 70% or more of original capacity, EcoFlow to 80%. The headline differences are output and sockets. EcoFlow’s spec table gives the DELTA 3 Plus 1,800W continuous and 3,600W surge through four UK mains sockets; Jackery’s gives the 1000 v2 1,500W continuous and 3,000W surge through two. EcoFlow adds X-Boost to 2,400W for heaters and kettles, which its manual says is off by default on the Plus and unavailable while the unit is charging.

Jackery’s unit is the lighter and smaller box: 10.8kg and roughly 33 × 22 × 25cm on Jackery’s spec table, against about 12.5kg and 40 × 20 × 28cm for the DELTA 3 Plus on EcoFlow’s. For USB, Jackery lists one 100W and one 30W USB-C plus an 18W USB-A; EcoFlow lists two USB-C at up to 140W each and two USB-A at up to 36W. The DELTA 3 Plus is rated IP65 against dust and water on EcoFlow’s page; Jackery’s UK page gives no rating for the 1000 v2, so we don’t either.

This is the size for a fridge-freezer. Its compressor cycles, so its average draw is far below its running draw: our sizing guide plans on 40–80W, and dividing the kWh/annum on the energy label by 8.76 gives your own model’s average. Jackery’s comparison page works out runtimes as capacity × 0.85 ÷ load; on that sum, 40–80W gives roughly 11–22 hours on either unit, an estimate only. Check the compressor’s start-up demand against the surge rating, as Jackery’s tables advise. Read power cut food safety before powering a fridge at all, and power station for a fridge freezer for the settings.

Choose the DELTA 3 Plus for more sockets, more output headroom, 1,000W of solar input and the option of adding a battery. Choose the Explorer 1000 v2 if weight matters more than headroom and you want a fixed, simpler unit; if you want Jackery and expansion, Jackery’s 1000 Plus v2 is the one to compare, not the 1000 v2.

About 2kWh: Explorer 2000 v2 vs DELTA 3 Max Plus

Here the brands part company on output. EcoFlow’s spec table gives the DELTA 3 Max Plus 3,000W continuous, 6,000W surge and 3,900W with X-Boost, through four sockets rated at 13A each. Jackery’s table gives the Explorer 2000 v2 2,200W continuous and 4,400W surge through two sockets, 10A maximum. Kettles run up to 3kW, so the Max Plus is the only one of the four rated to run a 3kW kettle within its continuous rating, at the limit, with nothing else on; on the 2000 v2 a 3kW kettle exceeds the rating. Check the plate on your own kettle.

Jackery’s answer is weight and a published cycle figure. The Explorer 2000 v2 is 17.5kg on Jackery’s UK spec table against about 22.1kg for the Max Plus on EcoFlow’s, and Jackery describes it as the lightest and smallest 2kWh lithium iron phosphate unit, a maker’s claim. Jackery rates it for 4,000 cycles to 70% or more; EcoFlow’s UK page says the Max Plus delivers power “for over 10 years” but prints no cycle count, so the two can’t be compared on that. Noise is quoted at different points, under 30dB for the Jackery and 25dB or less at 600W for the EcoFlow, so neither figure shows which is quieter.

The Max Plus takes DELTA Pro 3 and other EcoFlow extra batteries to 10kWh, per its spec table; the 2000 v2 takes none. Jackery’s own comparison page makes a point that holds for both brands: extra batteries add cost, weight and the energy needed to recharge, and do not raise continuous output. For home oxygen, EcoFlow’s manuals say its power stations are not intended for life-sustaining medical equipment; the Jackery pages we read say nothing either way. Plan on the back-up cylinder your oxygen supplier provides, and read running medical equipment in a power cut.

Choose the DELTA 3 Max Plus to run several appliances at once, boil a 3kW kettle or add storage later. Choose the Explorer 2000 v2 if it has to be carried upstairs or to a car, you want a quoted cycle rating, and 2,200W covers what you’d actually plug in.

Charging and solar

Mains recharging is EcoFlow’s clearest win. EcoFlow’s spec tables give the DELTA 3 Plus 0–100% in 56 minutes from a 1,500W input and the DELTA 3 Max Plus 0–80% in 47 minutes and full in 68 from 2,300W. Jackery’s tables give both the 1000 v2 and 2000 v2 about 1.7 hours as standard, with a faster “Emergency” charge set in the app: about an hour on the 1000 v2 and 1.33 hours on the 2000 v2. Jackery’s own buying guide says frequent use of that mode can stress the battery and is best saved for last-minute needs, so plan on the 1.7-hour figure for everyday use.

Solar is a wider gap. Jackery lists a maximum solar input of 400W on both units; EcoFlow lists 1,000W (two 500W inputs) on both of its, which its tables turn into 70 minutes to full on the DELTA 3 Plus. Jackery quotes roughly 3.8 hours for the 1000 v2 from two of its 200W panels, though its pages give different figures for the 2000 v2, so take any solar time as a fair-weather estimate. Jackery’s 2000 v2 FAQ says some of its own panel models need their adaptor removed and others need it kept, so check which connector your panel needs. See solar backup for a power cut.

From a car, Jackery quotes about 12 hours for the 1000 v2 and about 24 for the 2000 v2 from a 12V socket; the 1000 v2’s car cable is sold separately. EcoFlow quotes far faster figures, 1.3 hours to full on the DELTA 3 Plus and 0–80% in 95 minutes on the Max Plus, but only through its separately sold alternator chargers; its plain 12V car input is 8A. For a home that will mostly recharge from the mains between cuts, none of this decides it.

Switchover, apps and settings before a cut

These units can sit between the wall and a router or fridge as a UPS: mains passes through until it fails, then the battery takes over. EcoFlow quotes under 10 milliseconds on the DELTA 3 Plus; the DELTA 3 Max Plus spec table we read gives no switchover figure, so ask EcoFlow if UPS use matters. Jackery quotes 20 milliseconds or under on both the 1000 v2 and 2000 v2, and lists the 2000 v2 as UL1778 certificated. Either quoted time is quick enough for most routers, but it is not a guarantee: test your own router on the unit, both while it charges and once it is full.

The settings matter more than the brand. EcoFlow’s manuals say the AC output switches off after a set idle time, which can catch a fridge between compressor cycles, so set the AC timeout to “never” in the EcoFlow app; X-Boost also lives there. Jackery’s UK pages document fewer such settings for the v2 units, with Emergency and quiet charging set in its app and charging schedules and a battery reserve documented only on the 1000 Plus v2. Fewer documented settings is not proof there is no auto-off, so read the manual and run a trial night.

For a CPAP, ResMed’s battery guide puts its AirMini and AirSense 10 at roughly 4–20W from 12V with the humidifier off and strongly recommends its DC converter from the car socket over an inverter; it says most of its heated humidifiers must not be used with an inverter. All four units have a 12V socket at 10A. Agree it with your sleep service first, and read power station for a CPAP. Update either brand’s firmware while the power is on, never during a cut.

Neither brand puts carbon monoxide in your home: these are batteries, not engines. The CO warning belongs to petrol and diesel generators, which GOV.UK says must never run indoors and should sit at least 6 metres from the house with the exhaust facing away from windows and doors.

Where Jackery is the better choice

Weight. On the makers’ UK spec tables, the Explorer 1000 v2 is 10.8kg to the DELTA 3 Plus’s 12.5kg, and the Explorer 2000 v2 is 17.5kg to the Max Plus’s 22.1kg. If the unit lives in a cupboard and comes out for the fridge, the lighter box gets used.

A quoted cycle rating at 2kWh. Jackery rates the 2000 v2 for 4,000 cycles to 70% or more; EcoFlow says “over 10 years” for the Max Plus but gives no cycle figure. For a few cuts a year neither will wear out, but if you’ll cycle daily with solar, Jackery is the one that publishes a number.

Simplicity. Two sockets, no boost mode, fewer app settings documented: less to get wrong at 2am. Jackery’s pages also list a quiet charging mode, under 22dB on one page and under 30dB on another, for a bedroom. If you want Jackery with expansion, its 1000 Plus v2 and 2000 Plus v2 take extra batteries and are rated by Jackery for 6,000 cycles, so the choice is not “EcoFlow expands, Jackery doesn’t”. Where EcoFlow is plainly ahead on these units: output, sockets, mains and solar charging speed, a faster switchover claim on the DELTA 3 Plus, integrated expansion, and a flat five-year warranty and IP65 on the DELTA 3 Plus.

UK warranty and support: what each brand publishes

EcoFlow UK’s warranty table gives the DELTA 3 Plus five years and the DELTA 3 Max Plus three years plus two more on registration in the EcoFlow app. Jackery’s UK product pages for both the 1000 v2 and 2000 v2 carry a “3+2 years” line, and the 2000 v2 page says to register for the extended warranty through Jackery’s online form; its extension page adds that channel-partner orders with several packages need a separate request for each product. The pages we read don’t say whether a direct purchase needs the form, so submit it wherever you buy, Amazon or Jackery’s own store.

Both publish UK company details. Jackery’s UK terms give a company number and a London address; EcoFlow’s contact page gives a company number, a London address, an email and a UK freephone support line on weekdays, 08:00 to 16:00. Jackery’s user-guides page lists a UK freephone line seven days a week, 07:00 to 19:00, while its policy page gives weekday hours for a phone line, so check which applies before you rely on it. A UK address and phone line are not evidence of service quality either way.

Owner reviews of both brands praise the build and performance, and both brands also attract complaints about slow replies and drawn-out warranty claims, so register your purchase on day one and keep the receipt. Owners of both also mention paid add-ons at checkout, such as delivery protection or extra cover; decide on those before you reach the basket. Waiting for a sale?
