Detailed overview: EcoFlow Delta 3 1024Wh portable power station
The EcoFlow Delta 3 is a 1024 Wh portable power station designed to be the do-it-all solution: powerful enough for the home, compact enough for travel. It is built on a LiFePO4 (lithium iron phosphate) battery that offers 4000 charge cycles before dropping to 80% capacity, meaning up to ten years of regular use, 25% above the industry standard.
On power, it delivers 1800 W of continuous output, with X-Boost technology pushing up to 2400 W to run demanding resistive appliances (kettle, hair dryer, hob, small tools). Enough to run the vast majority of household devices. Its recharge is one of its flagship strengths: 0 to 100% in just 56 minutes from a mains socket, with five recharge methods in total (mains, solar up to 500 W, alternator charger, smart generator and combined mains + solar charging).
Its capacity is expandable from 1 to 5 kWh by adding Delta 3, Delta Pro 3, Delta 2 or Delta 2 Max extra batteries, letting you start small then grow as needed. In a power cut, its inverter function (automatic switchover) takes over to keep your essential devices powered. EcoFlow backs it with a 5-year warranty.
Compact, fast to recharge and scalable, the Delta 3 is for anyone who wants a versatile power station for camping, remote work, the motorhome or home backup power, with the longevity of LiFePO4 chemistry.

What is this power station best for?
-
Motorhome & Van life Ideal
Expandable to 5 kWh and recharged in under an hour, the Delta 3 accompanies a van or motorhome for several days: its base 1024 Wh power the fridge, lighting, ventilation, water pump and light cooking, and adding an extra battery multiplies autonomy for long trips. Its 1800 W occasionally accept a hungrier appliance, and its four outlets share power without a strip. A full recharge in 56 minutes tops up at a service area during a break, and a solar input up to 500 W ensures autonomy in the wild. Compact (12.5 kg) and quiet (30 dB), it preserves the calm of nights aboard.
-
Remote work Ideal
The Delta 3 is a reliable base for a mobile workstation: its 1800 W run a computer, one or two monitors, a printer, the router and lighting, and its UPS function (switchover under 10 ms) protects your data at the slightest micro-cut, never interrupting a video call or a render. Its 1024 Wh ensure long hours of connectivity, expandable to 5 kWh to cover several days without an outlet. Its two 100 W USB-C ports recharge laptops and tablets along the way, and a full recharge in 56 minutes brings it back online quickly between meetings. Compact (12.5 kg), it moves easily from office to garden or co-working spot.
-
Home & Power cuts Suitable
During an outage, the Delta 3 secures the essentials with top-tier responsiveness: its UPS function switches over in under 10 ms, an imperceptible delay that keeps the internet box, computer, lighting and a fridge running without a reboot. Its 1024 Wh cover these loads for several hours, and its expansion to 5 kWh with add-on batteries lets it last much longer during a prolonged failure. Its 1800 W accept an occasionally hungry appliance, and a full recharge in 56 minutes tops it up quickly once power returns. LiFePO4 chemistry (4000 cycles) and a 5-year warranty make it a reliable, scalable backup; to cover a whole home for several days from the start, choose a higher capacity or the expansion.
-
Job site & Tools Suitable
On an off-grid site, the Delta 3 brings versatile power in a light format: its 1800 W (3600 W peak) start and run a drill, sander, jigsaw or small compressor, and its four outlets feed several stations. Its 1024 Wh cover a good part of the day, and its express recharge (56 minutes) tops it up between tasks, without the noise or fumes of a generator. At 12.5 kg it moves easily from point to point. For very hungry tools or a full day, expansion to 5 kWh brings the needed margin.
-
Photo & Video Suitable
On a multi-hour shoot, the Delta 3 makes a reliable power station: its 1024 Wh and fast USB-C charging replenish many mirrorless camera batteries, drone packs and mics, and its 1800 W run an LED light, an on-set monitor or a multi-charging station. Its four outlets and USB-C ports cover all the gear without a strip, and its 30 dB operation stays discreet on set. A full recharge in 56 minutes cuts downtime between sequences, and expansion to 5 kWh covers a long production day without watching the gauge.

A selection of photovoltaic panels that suit this station's solar input (up to 60V / 500W), best match first.
Comparison
At around £599 to £770, the EcoFlow Delta 3 compares with roughly 1 kWh power stations, targeted by searches such as "portable power station" or "1000W power bank". Here is how it sits against three references: the Anker SOLIX C1000, the Bluetti AC180 and the Jackery Explorer 1000 v2.
| Criterion | EcoFlow Delta 3 | Anker SOLIX C1000 | Bluetti AC180 | Jackery Explorer 1000 v2 |
|---|---|---|---|---|
| Capacity | 1024 Wh | 1056 Wh | 1152 Wh | 1070 Wh |
| AC output | 1800W (X-Boost 2400W) | 1800W | 1800W | 1500W |
| Recharge 0-100% | 56 min | 58 min | 90 min | 60 min |
| Expandable | Yes (up to 5 kWh) | Yes | No | No |
| Observed price | ≈ £649 | ≈ £683 | ≈ £598 | ≈ £683 |
In short, the Delta 3 stands out for one of the fastest recharges in the segment, its X-Boost that pushes the power ceiling and its expandability up to 5 kWh, where the Bluetti and Jackery are not expandable. The Anker SOLIX C1000 is its most direct rival, with near-identical capacity and recharge. For a scalable, fast 1 kWh station, the Delta 3 offers one of the best feature-to-price ratios.

Our tester's review: Christophe Delpuech
We used the Delta 3 both at home, to cover power cuts, and on weekends in a van, and it is its versatility that stands out. The 1800W output handles a kettle, an induction hob or tools without flinching, and the X-Boost function pushes up to 2400W for the most demanding resistive appliances, which is rare at this price. The recharge is striking: plugged into the wall, it goes from 0 to 100% in under an hour, you top it up during a meal before setting off again. The LiFePO4 battery is reassuring, 4000 cycles claimed, meaning a decade of regular use, and its quiet operation makes it pleasant indoors. As backup, the automatic switchover during a cut kept our router and fridge running without us noticing. Two honest caveats: 1024Wh is a mid-range capacity, you need the add-on batteries to last several days, and the weight (around 12 kg) makes it transportable but not light. For a reliable, fast do-it-all station, it is a safe bet.
