Specifications
Last checked on 10 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 1,024 Wh |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LFP |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | 4,000 cycles to 80% capacity |
| ExpansionExtra battery units that add storage to the same system. | Up to 5 kWh with the extra batteries of the DELTA 3, DELTA Pro 3, DELTA 2 Max or DELTA 2 |
| Output | |
| AC output (continuous)The power it can deliver all the time. Add up the watts of what you want to run at once and stay below this. | 1,800 W, 4 AC outlets |
| AC output (surge)A short burst above the continuous rating, for appliances that draw more power when they start. | 3,600 W |
| X-BoostA mode that can run some devices above the normal output rating by lowering the voltage it supplies. Not suitable for every device. | Runs devices up to 2,400 W |
| USB-APorts for phones, tablets and small devices. | 2 ports, 36 W max each (fast charging) |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | 2 ports, 140 W max each |
| Car outletA 12 V socket like the one in a car, for car accessories. | 1 outlet, 12.6 V 10 A, 126 W max |
| DC5521A small round DC connector used by routers, cameras and LED lights. | 2 ports, 12.6 V 3 A max each |
| Charging | |
| AC chargingHow fast it charges from a wall socket. Higher means a shorter wait. | 1,500 W |
| Time to charge from the mainsHow long a full charge takes from a wall socket. | 56 minutes (1,500 W) |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | DC input 11-60 V, 2 x 500 W max |
| Solar charging timeHow long a full charge takes from solar panels, in the conditions the maker names. | 70 minutes (at 2 x 500 W) |
| Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road. | 800 W (alternator charger), 1.3 hours |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | Under 10 ms (UPS), with HID support for NAS/UPS use |
| Housing and warranty | |
| Dimensions (L × W × H)Check the space before you buy, including room around it for airflow and cables. | 398 × 200 × 284 mm (EcoFlow does not say which number is which axis; the DELTA 3 Extra Battery is 398 × 200 × 198 mm) |
| WeightMatters for lifting, wall mounting and moving it. | 12.5 kg or less (one figure for the DELTA 3 and DELTA 3 Plus) |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Not stated |
| Noise levelFan noise while working. | Below 30 dB at 600 W; below 40 dB at 1,200 W |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP65 for the battery pack |
| ConnectivityHow you monitor and control it, usually through an app. | EcoFlow app (time-of-use and storm-warning features) |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 5 years |
How long will it run your devices?

The estimate assumes 85% of the rated capacity is usable after conversion losses. EcoFlow does not state this figure, so we use a cautious assumption. Real running times vary with temperature, battery age and how each device draws power.

Rules where you live
A portable power station is not wired into your home, so it is simple to use almost anywhere. Connecting one to your home circuits to power the house is different, and the rules for that vary by country. See our country guides for the rules, incentives and prices where you live.

Where this information comes from
We have not tested the DELTA 3 Plus. Every figure above comes from the DELTA 3 Series page on EcoFlow's UK site, which has one specification table for the DELTA 3 and the DELTA 3 Plus; we only show the DELTA 3 Plus values, last checked on 10 November 2026. A value that the page does not state is shown as not stated. The DELTA 3 Plus is a different product from the DELTA 3 Classic and the DELTA 3 Max.
We do not show prices, because they change often and differ between sellers.

What can the DELTA 3 Plus run?
EcoFlow rates it at 1,800 W continuous and 3,600 W surge, with X-Boost reaching 2,400 W for suitable devices. That covers a fridge, TV and computer, and with X-Boost some kettles and hair dryers. Divide 1,024 Wh by the load for a rough running time.
How much can the DELTA 3 Plus store?
One unit holds 1,024 Wh. EcoFlow lists expansion to 5 kWh with extra batteries from the DELTA 3, DELTA Pro 3, DELTA 2 Max or DELTA 2.
What is the difference between the DELTA 3 and DELTA 3 Plus?
On EcoFlow's table the Plus has two 500 W solar inputs (the DELTA 3 has one), 36 W USB-A and 140 W USB-C ports (18 W and 100 W on the DELTA 3) and HID support for UPS use. Both list 1,024 Wh and 1,800 W.
