Quick answer
For most UK buyers EcoFlow is the stronger all-rounder: it charges faster on standard mains mode, adds X-Boost to run resistive kit like kettles and heaters above its rated output, and offers expandable models where Jackery offers none, with its best-value 1kWh unit (the Delta 3 Classic at £399) undercutting Jackery's equivalent by £100. Choose Jackery if you want the simplest range in the market, the lightest unit in every capacity class, a clear 5-year warranty and a proven best seller; its Explorer 1000 v2 is Amazon UK's category best seller for good reason. The split in one line: EcoFlow for charging speed, output headroom and expansion; Jackery for weight, simplicity and warranty. Prices from our September 2026 check.
EcoFlow or Jackery: which power station brand should you buy?
For most UK buyers EcoFlow is the stronger all-rounder, but the honest answer depends on what you weigh most. EcoFlow charges faster on standard mains mode, adds X-Boost to push resistive loads above its rated output, and sells expandable models where nothing in Jackery's current v2 line grows at all. Its best-value 1kWh unit, the Delta 3 Classic at £399, undercuts Jackery's Explorer 1000 v2 at £499 by £100.
Jackery answers with the things a spec sheet undersells: it is the biggest, most proven name in the category, it builds the lightest unit in every capacity class we compare here, its range is the simplest in the market to choose from, and every v2 model carries a published 5-year (3+2) warranty. The Explorer 1000 v2 was Amazon UK's category best seller at our September 2026 check.
So the split is clean. Buy EcoFlow for charging speed, output headroom and the option to expand later. Buy Jackery for the lightest, simplest, best-supported unit at each size, as long as you are certain you will not need to grow it.
EcoFlow in short
EcoFlow moves faster than any other brand we cover, and the engineering backs the pace. Three of its current models recharge fully from the mains in an hour flat, and X-Boost stretches a modest inverter to run resistive kit like kettles and hair dryers by trimming voltage, so a 1,800W unit can drive loads up to 2,400W that its rating alone would rule out.
The range splits into two lines. The River line is the small, carryable end, built around the 286Wh River 3 Plus, which grows by wire-free stacking rather than by buying a bigger box. The Delta line runs from 1,024Wh to 2,048Wh, and on a Delta the word "Plus" signals an expansion port, more solar input and a stronger inverter, not just a bigger battery. Expandability is a real EcoFlow advantage: the Delta 2 grows to roughly 3kWh and the Delta 3 Max Plus expands to 10kWh.
The catch is the naming. EcoFlow's line-up changes so quickly that the labels have stopped making obvious sense: the "River 3 Max" is not a separate model but the River 3 Plus bundled with a stacking battery, and one Delta 3 costs less than the model it outperforms. It is a range that rewards reading the small print.
Jackery in short
Jackery is the biggest name in this market, and the current v2 line earns much of the reputation. It builds the lightest unit in its class at every size, the range is a simple four-model ladder, and every model runs a 20ms UPS switchover for basic backup. The Explorer 1000 v2 is the one most people should look at first, and the crowd agrees: it was Amazon UK's category best seller at our check.
Two things need saying plainly, though, because they shape the whole comparison. Nothing in the v2 line is expandable, so the capacity you buy is the capacity you keep for the life of the unit. And the headline "full in 1 hour" charging figures are app-enabled emergency modes; standard mains charging runs 1.7 to 2 hours depending on the model. Neither is a fault, but both matter when you line Jackery up against EcoFlow.
Where Jackery is hard to beat is weight, simplicity and support. Its SolarSaga panels pair cleanly with every model, and each v2 unit carries a 5-year (3+2) warranty. If you want to buy once, keep it light and not think about accessories, Jackery is built for you.
Tier by tier: EcoFlow vs Jackery
Both brands sell across the same capacity classes, so the fairest way to choose is to compare like with like. Every figure below traces to the manufacturer's UK listing, with prices from our September 2026 check.
Around 300Wh: River 3 Plus vs Explorer 240 v2
The entry tier, for charging phones, cameras, lights and a laptop for a weekend.
| Spec | EcoFlow River 3 Plus | Jackery Explorer 240 v2 |
|---|---|---|
| Capacity | 286Wh LiFePO4 | 256Wh LiFePO4 |
| AC output | 600W (1,200W X-Boost) | 300W (600W surge) |
| Weight | 4.7kg | 3.6kg |
| Mains recharge | 60 min | 120 min standard (60 min app emergency) |
| Solar input | up to 220W | up to 100W |
| Expandable | Yes, to 858Wh by wire-free stacking | No |
| UPS switchover | 10ms | 20ms |
| Rugged rating | IP54 splash, 1m drop rated | Not rated |
| Price | £219 | £189 |
This tier goes to EcoFlow on capability. The River 3 Plus carries double the AC output, twice the solar input, a faster standard recharge, IP54 splash protection with a 1m drop rating, and the trick neither Jackery small unit can match: it stacks wire-free to 858Wh if your needs grow later. The Explorer 240 v2 wins on the two things Jackery always wins on, weight and price: at 3.6kg and £189 it is the lighter, cheaper grab for someone who only ever charges USB kit and never wants to expand. For a small station you might build on, the River 3 Plus is the smarter buy.
Around 1kWh: Delta 3 Classic and Delta 2 vs Explorer 1000 v2
The sweet spot for most buyers, and the tier where this comparison is really decided.
| Spec | EcoFlow Delta 3 Classic | EcoFlow Delta 2 | Jackery Explorer 1000 v2 |
|---|---|---|---|
| Capacity | 1,024Wh LiFePO4 | 1,024Wh LiFePO4 | 1,070Wh LiFePO4 |
| AC output | 1,800W (2,400W X-Boost, 3,600W surge) | 1,800W (2,400W X-Boost, 2,700W surge) | 1,500W (3,000W surge) |
| Weight | 12.1kg | 12kg | 10.8kg |
| Mains recharge | 60 min | 80 min | 102 min standard (60 min app emergency) |
| Solar input | up to 500W | up to 500W | up to 400W |
| 12V car socket | No | Yes | Yes |
| Expandable | No | Yes, to roughly 3kWh | No |
| Cycle rating | 10-year lifespan claim | 3,000 cycles to 80% | 4,000 cycles to 70% |
| Price | £399 | £449 | £499 |
Three points decide it. On price and charging, EcoFlow leads: the Delta 3 Classic is £100 cheaper than the Explorer 1000 v2, recharges fully in a claimed 60 minutes against Jackery's 102-minute standard mode, and pushes 1,800W of output (2,400W with X-Boost) against Jackery's 1,500W. If you charge in short windows and want the strongest inverter for the money, EcoFlow.
But read the Delta 3 Classic's one omission before you buy it: it has no 12V output of any kind, no car socket and no DC barrel ports, so a compressor cool box or any 12V campervan kit is out. Both the Delta 2 and the Explorer 1000 v2 keep a 12V car socket. If you need 12V, EcoFlow's answer is the Delta 2 at £449, which also adds expansion to roughly 3kWh, the one thing no Jackery here can do.
Jackery's case is weight, longevity and the crowd. At 10.8kg the Explorer 1000 v2 is the lightest 1kWh unit of the three and the class best seller, and its 4,000-cycle rating outlasts the Delta 2's 3,000, though note Jackery rates its cycles to 70% of capacity where EcoFlow rates the Delta 2 to 80%, so the two figures are not measured on the same line. For a full head-to-head see EcoFlow Delta 2 vs Jackery Explorer 1000 v2.
Around 2kWh: Delta 3 Max vs Explorer 2000 v2
The tier for campervans, long trips and home backup.
| Spec | EcoFlow Delta 3 Max | Jackery Explorer 2000 v2 |
|---|---|---|
| Capacity | 2,048Wh LiFePO4 | 2,042Wh LiFePO4 |
| AC output | 2,400W (3,200W X-Boost, 4,800W surge) | 2,200W (4,400W surge) |
| Weight | 20.3kg | 17.5kg |
| Mains recharge | 68 min (percentage range unlabelled) | 102 min standard (80 min app emergency) |
| Solar input | up to 500W | up to 400W |
| 12V car socket | Yes | Yes |
| Expandable | No (only the Max Plus expands, to 10kWh) | No |
| Cycle rating | Not published | 4,000 cycles to 70% |
| Price | £999 | £899 |
Closer than the tier above. The Delta 3 Max carries more output (2,400W, or 3,200W with X-Boost) and more solar headroom, but EcoFlow does not clearly publish a 0 to 100% mains figure for it: the spec table lists a 68-minute time without a labelled percentage range, so treat the charging edge here as unproven rather than banked. Neither of these two is expandable, an important note on the EcoFlow side, because expansion belongs to the pricier Delta 3 Max Plus, not this unit.
Jackery again takes weight and price: the Explorer 2000 v2 is nearly 3kg lighter at 17.5kg, which it claims as the lightest in the 2kWh class, and it is £100 cheaper at £899. Its standard 102-minute recharge is the honest everyday figure; the "Super Fast Charge" claim is the app's emergency mode. For the full spec-by-spec breakdown see Jackery Explorer 2000 v2 vs EcoFlow Delta 3 Max.
Around 3kWh: no like-for-like EcoFlow
Here the comparison breaks, and it is worth being straight about it. In our current data EcoFlow has no single ~3kWh portable unit to line up against the Jackery Explorer 3000 v2. EcoFlow's route to that capacity is expansion: the Delta 3 Max Plus is a 2,048Wh unit that grows to 10kWh by adding batteries. Jackery's route is a single fixed box.
| Spec | EcoFlow Delta 3 Max Plus | Jackery Explorer 3000 v2 |
|---|---|---|
| Base capacity | 2,048Wh LiFePO4 | 3,072Wh LiFePO4 |
| Path to 3kWh+ | Add an expansion battery (to 4,096Wh, up to 10kWh) | Fixed at 3,072Wh, no expansion |
| AC output | 3,000W (3,900W X-Boost, 6,000W surge) | 3,600W (7,200W surge) |
| Weight | 22.1kg | 27kg |
| Mains recharge | 0 to 80% in 47 min (full time not labelled) | 108 min standard |
| Solar input | up to 1,000W | up to 1,000W |
| Cold-weather rating | Not published | Discharge rated to -15C |
| Price | £1,099 base | £1,599 |
These are not equivalents, so choose by shape. If you want a genuine 3kWh single unit out of the box with strong 3,600W output and a cold-weather discharge rating down to -15C, the Jackery Explorer 3000 v2 is the straightforward pick, and it also outputs across three AC sockets. If you would rather start at 2kWh and expand only if and when you need it, EcoFlow's Delta 3 Max Plus reaches far higher (10kWh) for a lower entry price, at the cost of buying batteries later.

Which should you buy, by use case
Camping and weekend trips. Jackery for pure carry weight and simplicity: it builds the lightest unit at every size, and the Explorer 1000 v2 is the proven class best seller. EcoFlow if you want faster top-ups between trips or the small River 3 Plus that can stack to 858Wh later.
Campervans. Check the 12V socket first. Jackery keeps a 12V car socket across the v2 line. EcoFlow does too on most models, with one trap: the Delta 3 Classic has no 12V output at all, so avoid it for a compressor fridge and reach for the Delta 2 or a Delta 3 Max instead.
Budget. EcoFlow, at the 1kWh sweet spot: the Delta 3 Classic at £399 is £100 under Jackery's Explorer 1000 v2 and out-specs it on output and charging, as long as you do not need its missing 12V port. At the very bottom, Jackery's Explorer 240 v2 at £189 is the cheapest entry unit here.
Features and expandability. EcoFlow, clearly. X-Boost runs resistive loads above the rated inverter output, standard-mode charging is faster, and expandable models exist (Delta 2 to roughly 3kWh, Delta 3 Max Plus to 10kWh) where no current Jackery v2 grows at all.
Simplicity, weight and warranty. Jackery. Four models, the lightest box in every class, SolarSaga panels that pair without fuss, and a published 5-year (3+2) warranty on every v2 unit. If you want to buy once and not think about it, this is the brand.
