Every EcoFlow power station sold in the UK, compared (2026)

This is the DELTA 3 Classic with the door left open. Same 1,024Wh LiFePO4 pack, which EcoFlow rates at 4,000 cycles to 80% (it quotes the Classic only as a 10-year life), same 1,800W output, but with an extra-battery port that takes it to 5kWh, dual solar inputs up to 1,000W, 140W USB-C ports and a 56-minute mains recharge. For a home that wants to start with one unit and grow into whole-fridge, whole-day backup, it is the better buy than the Classic; for a home that will never expand, the Classic does the same job for less. EcoFlow's UK store listed it as available to order rather than in stock when we checked; Amazon had it in stock at the same price.

Best for Households that want the fridge, router and phones covered for a long power cut and may add a second battery later — the expandable 1kWh choice.

• Expandable to 5kWh with EcoFlow's extra batteries, and dual solar inputs up to 1,000W — the 1kWh unit you won't outgrow
• LiFePO4 cells rated for 4,000 cycles to 80%, IP65-rated battery pack, five-year UK warranty
• Full mains recharge in 56 minutes, under-10ms UPS switchover, and four mains sockets with 140W USB-C for laptops

• Costs more than the DELTA 3 Classic for the same capacity and output — only worth it if you'll use the expansion port or the solar inputs
• At 12.5kg it is a two-hands carry, not something to move around casually
• Kettles and electric heaters remain off the menu: 1,800W (2,400W with X-Boost) covers essentials, not heating

Who shouldn't buy it: You know you'll never add a battery or solar panels — the DELTA 3 Classic is the same power station without the ports you won't use. And if a fridge isn't on your list, a 300Wh unit or a big power bank covers phones, lights and the router for a fraction of the price.

The DELTA Pro 3 is the top of EcoFlow's portable range: 4,096Wh, 4,000W output rising to 6,000W with X-Boost, 2,600W of solar input and expansion to 12kWh. EcoFlow rates the LiFePO4 pack at 4,000 cycles to 80%. It is a wheeled suitcase-style unit, 51.5kg without extra batteries, built for people who want to run a fridge, freezer and kitchen appliances together. Next to the DELTA 3 Max Plus it offers twice the capacity and a third more output at more than twice the weight; most households will be well served by the smaller unit.

Best for Several days of whole-home essentials and heavy kitchen appliances at once, if you can handle a wheeled 51.5kg unit.

• 4,096Wh and 4,000W, enough to cover several appliances at once
• Up to 2,600W of solar input and expansion to 12kWh
• Wheels and a pull handle, and a rated 4,000 cycles to 80%

• 51.5kg is not a unit to lift; plan where it lives and where it is used
• Costs more than twice as much as the 2kWh units, which suit most single-fridge needs
• One long-term reviewer had the unit cut its output twice with a fault warning that a full power cycle cleared, so keep the reset steps to hand

Who shouldn't buy it: You only need a fridge, router and phones covered: a 1kWh unit does that for a fraction of the cost and weight. Whole-house backup that needs to switch automatically also needs an electrician and a proper changeover, not just this unit.

The home-backup pick in EcoFlow's current range. 2,048Wh and a 3,000W output mean it runs a fridge-freezer, the boiler's pump and controls, the router, lights and chargers at the same time, and X-Boost stretches it to 3,900W for simple resistive loads. It recharges from empty in 68 minutes, takes 1,000W of solar, and its extra-battery port expands the system to 10kWh, which is what separates it from the plain DELTA 3 Max. At 22kg it lives where it is plugged in. EcoFlow does not publish a cycle-life figure for this model on its UK page, which is unusual for the brand, so we have not quoted one.

Best for A whole household through a day-long power cut — fridge-freezer, boiler controls, router, lights and phones together — with room to grow to 10kWh.

• 3,000W output (6,000W surge) runs the fridge-freezer, boiler controls, router and lights together — the step up from the plain DELTA 3 Max, which EcoFlow rates at 2,400W
• Expandable to 10kWh with one or two extra batteries, plus 1,000W of solar input, so it can anchor a proper home-backup setup
• Full recharge in 68 minutes from the mains, Wi-Fi and Bluetooth app control, and a 10ms UPS switchover

• 22kg: this is a stay-put unit, not a carry-to-the-car one
• EcoFlow's UK page states no cycle-life rating for it, unlike the DELTA 3 (4,000 cycles) — ask before you buy if longevity is your reason
• The full five-year warranty needs registration in the EcoFlow app; unregistered it is three years

Who shouldn't buy it: Your realistic power cut is a few hours, not a day: a 1kWh unit keeps the fridge cold and the phones charged for that, at half the price and weight. And if you have a heat pump or electric heating you hope to run, no portable unit does that — this covers essentials, not heating.

The DELTA 3 Max is the fixed-capacity sibling of the DELTA 3 Max Plus: the same 2,048Wh capacity at 20.3kg against the Plus's 22.1kg, but with 2,400W of output where the Plus gives 3,000W, 500W of solar input where the Plus takes 1,000W, and no extra-battery port where the Plus grows to 10kWh. EcoFlow quotes a 3-year warranty plus a 2-year extension. It is the choice for someone who knows 2kWh is the ceiling they need and wants it a little lighter than the DELTA 2 Max; anyone who may add batteries later should pay for the Plus.

Best for Two days of fridge and essentials from one 2kWh unit that is lighter than the DELTA 2 Max.

• 2,048Wh and 2,400W in 20.3kg, about 3kg lighter than the DELTA 2 Max
• AC recharge in roughly 68 minutes on the retailer's figure
• LFP pack with an app and a quiet rating of 25dB at 600W stated by a UK retailer

• No expansion port: capacity stays at 2kWh
• Solar input is 500W, half that of the Max Plus
• Five-year cover relies on registering for the extra two years

Who shouldn't buy it: You may want to grow past 2kWh or run heavier loads: the DELTA 3 Max Plus expands to 10kWh. If you only need a fridge, a 1kWh unit costs much less.

The best-value model in EcoFlow's current 1kWh range, and the lowest-priced of its three: the same 1,800W output and LFP chemistry as the DELTA 2, a slightly faster 45-minute 0-80% mains recharge, and a 10ms UPS switchover. The trade-off is that this 'Classic' model's capacity is fixed: unlike the DELTA 2 there is no extra-battery port, so 1,024Wh is what you get.

Best for Keeping a fridge, router, phones and a few lights running through a multi-hour power cut, for households who won't need to expand capacity later.

• LFP cells EcoFlow rates for a 10-year lifespan, backed by up to 5 years' warranty (3 years standard, 2 more when registered in the EcoFlow app)
• Recharges 0-80% in 45 minutes on the mains (60 minutes to full), with a built-in 10ms UPS switchover for sensitive electronics like a router or NAS
• 1,800W continuous output (3,600W surge; up to 2,400W via X-Boost) covers most household essentials

• Unlike the DELTA 2, there is no extra-battery expansion port, so 1,024Wh is a hard ceiling — the standard DELTA 3 or DELTA 3 Plus (1-5kWh expandable) exist if you might want more later
• No 12V car-style DC output port, unlike the standard DELTA 3 / DELTA 3 Plus
• Only 5 outputs (2 AC, 1 USB-A, 2 USB-C), fewer than EcoFlow's DELTA 3 and DELTA 3 Plus

Who shouldn't buy it: You only need to keep phones, a tablet and a laptop topped up — a much cheaper power bank does that job. And skip this specific 'Classic' model if you think you'll want to add capacity later, since it has no expansion port; the standard DELTA 3 or DELTA 3 Plus do.

A well-judged mid-size unit for household backup: the long-life LFP battery, genuinely fast recharge and quiet operation make it a sensible first power station. Just size it to essentials, not the whole house.

Best for Keeping the essentials going in a power cut — fridge, broadband router, phones and a few lights.

• LFP (lithium iron phosphate) battery rated for roughly 3,000 cycles / ~10 years — far longer-lived than older lithium units
• Recharges 0-100% in about an hour from the mains, so it is ready again quickly between outages
• Light (~6.1kg), quiet, and ships with proper UK 3-pin sockets plus a 100W USB-C port

• 512Wh is modest — enough for low-draw essentials for several hours, not for running a home for a day
• Native 500W output means high-wattage appliances need X-Boost, and it still will not run a kettle, oven or electric heater

Who shouldn't buy it: You want to power high-draw appliances (kettle, microwave, heaters) or keep much of the home running — the capacity and 500W output are too small; step up to a Delta-class unit instead.

The sensible entry point to EcoFlow's current range: a 286Wh LiFePO4 pack rated for 3,000 cycles, three mains sockets, a 100W USB-C and a 12V socket, recharged from the wall in an hour. What sets it apart from other small units is the extra-battery system: an EB300 or EB600 clips on underneath with no cables, taking it to 858Wh if you later decide you want the fridge covered too. The under-10ms switchover means a router or desktop rides through the cut without noticing. Its 600W output (1,200W with X-Boost for simple heating loads) rules out kettles and most heaters, which is true of every unit at this size.

Best for Phones, a router, lights and a laptop through an evening's power cut, in a unit small enough to live in a cupboard — with the option to add capacity later.

• LiFePO4 cells rated for 3,000 cycles to 80% — EcoFlow puts that at roughly ten years of everyday use — with a five-year UK warranty
• Expandable without tools: an EB300 or EB600 extra battery attaches underneath, up to 858Wh, so you can start small
• Full recharge from the mains in 60 minutes, and an under-10ms UPS switchover for a router or home-office kit

• 286Wh on its own is a phones-lights-router unit: a fridge needs the extra battery or a bigger station
• 600W rated output, so kettles, toasters and fan heaters are off the menu even with X-Boost
• The base unit showed as sold out on EcoFlow's own UK store when we checked; Amazon had it at a slightly higher price

Who shouldn't buy it: You only need to keep phones and a tablet going — a 20,000-25,000mAh power bank does that for a fraction of the price. And if the fridge is the reason you're shopping, start at 1,000Wh (the DELTA 3 Classic or BLUETTI Elite 100 V2) rather than buying this and an extra battery.

The RIVER 3 is a small 245Wh unit with one 300W mains socket and a 3.55kg body; X-Boost lets it run some heating-element appliances up to 600W. EcoFlow quotes a one-hour mains recharge and 110W of solar input. It keeps a router, phones and LED lights running for many hours, but one socket and 300W rule out a fridge. Compared with the RIVER 3 Plus already on this page, it is the smaller and cheaper choice; the Plus adds capacity and a 600W output.

Best for Phones, router, lights and a laptop through a short power cut, at a size that fits a shelf or a grab bag.

• 3.55kg and a library-quiet rating under 30dB on EcoFlow's figures
• Full mains recharge in about an hour
• USB-C at 100W charges most laptops

• One mains socket and 300W means no fridge, kettle or heater
• 245Wh runs a router for roughly a day, but not much beyond that
• The standard model's UPS switchover is rated slower than the separate RIVER 3 UPS version

Who shouldn't buy it: You want to keep a fridge cold: step up to a 1kWh unit. If you only charge phones, a large power bank is cheaper.

The RIVER 2 Pro is a 768Wh unit with 800W of output, 1,600W under X-Boost, and 220W of solar input in a 7.8kg body. It is a good fit for a household that wants more than a 250Wh starter unit but not the weight of a 1kWh one. The recurring complaint from reviewers is the fan: EcoFlow's spec sheet gives noise up to 62dB when charging and discharging at high wattage, and testers describe it as intrusive at close range. Next to the 1,024Wh DELTA 3 Classic it has less capacity and no expansion, but it weighs about 4kg less.

Best for Router, lights and a small fridge for a few hours at a time, from a 7.8kg unit.

• 768Wh and 800W for 7.8kg, enough for a small fridge for part of a day
• 70-minute full recharge from the mains
• 220W of solar input

• Fan noise reported as loud during fast charging and heavy loads
• Not expandable, and 768Wh is tight for a fridge plus a freezer
• Older design with 3,000 rated cycles versus 4,000 on the newest EcoFlow units

Who shouldn't buy it: Quiet is a priority or you want to cover a fridge for more than half a day: a DELTA 3 Classic or DELTA 3 Plus has more capacity. For phones and a router alone, the RIVER 3 does the job at a lower cost.

The DELTA 2 Max doubles the DELTA 2's capacity to 2,048Wh and lifts output to 2,400W, with EcoFlow quoting 3,100W under X-Boost. It can take two extra batteries for 6kWh, and 1,000W of solar input is more than most 1kWh units manage. UK reviewers rate it as capable but heavy at 23kg, against about 12kg for the DELTA 2. For a home that wants a day or more of fridge and lighting cover it is a strong middle step; the newer DELTA 3 Max is lighter for the same capacity.

Best for A long power cut with a fridge, freezer, router and a few appliances, if you can live with a 23kg unit.

• 2,048Wh and 2,400W covers a fridge plus a kettle-free set of essentials for much longer than a 1kWh unit
• Expands to 6kWh with two extra batteries
• Up to 1,000W of solar input and a roughly 53-minute AC recharge to 80% on EcoFlow's figures

• 23kg makes it a two-handed lift that reviewers call at the limit of portability
• Fans can be heard under heavy loads on some reviewers' reports, though one long-run test found them unobtrusive at full rated output
• Older design that the lighter DELTA 3 Max now overlaps

Who shouldn't buy it: You will move it often or have steps to climb: the 16.5kg DELTA 3 1500 or a 1kWh unit is easier to handle. If you do not need 2kWh, you are paying for capacity you will not use.

The DELTA 3 1500 sits between the DELTA 3 Plus (1,024Wh) and the 2kWh class, with 1,536Wh, the same 1,800W output and a 16.5kg body. EcoFlow lists expansion to 5.5kWh and a 1,500W AC input that fills it in about 90 minutes. A UK retailer lists a 3,000-cycle LiFePO4 pack, so its cycle rating is below the DELTA 3 Plus's 4,000 on EcoFlow's own figures. It suits a household that finds 1kWh tight for a fridge plus a freezer but does not want the weight of a 2kWh unit.

Best for A middle step between 1kWh and 2kWh: enough for a fridge and essentials for a long evening and next day, at 16.5kg.

• 1,536Wh and 1,800W for 16.5kg, lighter than the 2,048Wh class
• Expands to 5.5kWh and takes 500W of solar
• Full recharge in about 90 minutes from the mains on EcoFlow's figure

• Solar input tops out at 500W, where the DELTA 3 Plus takes 1,000W
• Cycle rating quoted by a retailer is 3,000, below the DELTA 3 Plus's 4,000
• Few independent reviews or owner reports exist for this model yet, and reviewers of the closely related DELTA 3 Plus flag frequent fan noise

Who shouldn't buy it: You have only a fridge to cover: the 1,024Wh DELTA 3 Classic does that for less. If you want heavy appliances or several days of cover, step up to the DELTA 3 Max Plus.
