Detailed overview: EcoFlow Delta 3 Plus 1024Wh power station
The EcoFlow Delta 3 Plus is the enriched version of the Delta 3: it keeps the 1024 Wh LiFePO4 battery (4000 cycles, about 10 years of regular use), the 1800 W output (up to 2400 W with X-Boost technology), the fast 0-100% recharge in 56 minutes from the mains and the expandability from 1 to 5 kWh, while adding three concrete upgrades that justify its higher positioning.
The first is the dual solar input, up to 1000 W split across two MPPT controllers: it halves solar recharge time versus the Delta 3, a decisive asset in a van, a second home or an off-grid setup. The second is the presence of 140 W USB-C ports (versus 100 W on the Delta 3), enough to charge a powerful laptop at full speed without going through the mains socket.
The third, more discreet but important for a connected office, is an advanced inverter (UPS) compatible with the NAS and HID protocols: during an outage, its switchover under 10 ms keeps not only essential devices but also a network storage server and its peripherals running, avoiding the abrupt shutdown that can corrupt data. It offers 4 AC outlets, 2 USB-C 140 W ports, 2 USB-A ports and a 12 V output, and is controlled from the EcoFlow app (Wi-Fi and Bluetooth).
Identical in weight and size to the Delta 3 (12.5 kg), the Delta 3 Plus is for anyone who often recharges via solar, uses powerful USB-C devices or wants to secure a NAS. For simpler use, the base Delta 3 remains an excellent choice at a lower cost.

Rough estimate: real consumption varies, and very power-hungry appliances (heating elements) must stay below the output power.
What is this power station best for?
-
Home & Power cuts Ideal
The Delta 3 Plus is particularly at ease as home backup thanks to its advanced inverter: its UPS switchover under 10 ms protects the router, computer and lighting, and above all it supports the NAS and HID protocols, which shields a network storage server and its peripherals during an outage, where a classic station might cut a NAS and corrupt data. Its 1024 Wh cover these loads for several hours, expandable to 5 kWh with add-on batteries to last through a long outage. Its 1800 W (2400 W X-Boost) handle an occasionally demanding appliance, and its 0-80% recharge in 40 minutes tops it up fast when power returns. LiFePO4 cells (4000 cycles) and a 5-year warranty make it a reliable, scalable backup designed for the connected office.
-
Remote work Ideal
For a demanding mobile workstation, the Delta 3 Plus goes further than the base Delta 3: its two USB-C ports reach 140 W, enough to charge a powerful laptop at full speed while running screens, router and lighting on its 1800 W. Its UPS function (switchover under 10 ms) with NAS and HID support protects an entire connected workstation, down to the storage server, without ever interrupting a render or a video call. Its 1024 Wh ensure long hours of connectivity, expandable to 5 kWh, and its full recharge in 56 minutes brings it back online fast. Compact and quiet (30 dB), it suits a studio, a creative workshop or a shared workspace.
-
Motorhome & Van life Ideal
Expandable to 5 kWh and built for solar, the Delta 3 Plus accompanies a van or motorhome for several days: its 1024 Wh run fridge, lighting, ventilation, water pump and light cooking, and an add-on battery multiplies autonomy. Its dual solar input up to 1000 W (two MPPT controllers) recharges twice as fast as a single input, a real asset at a stopover on a sunny day, and its 56-minute mains recharge tops it up at a service area during a break. Its 1800 W handle an occasionally demanding appliance, and its quiet operation (30 dB) preserves the calm of nights. At 12.5 kg, it adds no weight over the base Delta 3.
-
Off-grid & Solar Suitable
Its dual solar input up to 1000 W (two MPPT) makes the Delta 3 Plus an excellent solar storage core for an off-grid location: cabin, workshop, tiny house or second home. It recharges fast in the sun and runs a fridge, lighting, pump and tools on its 1800 W, while its expansion to 5 kWh increases autonomy as needed. Its LiFePO4 cells (4000 cycles) withstand years of daily cycling, and app control makes it easy to track production and consumption. For year-round permanent self-consumption, add panels and expansion batteries.
-
Job site & Tools Suitable
On an off-grid worksite, the Delta 3 Plus delivers versatile power and fast solar recharging: its 1800 W (3600 W surge) start and run a drill, sander, jigsaw or a small compressor, and its four outlets feed several stations. Its 1024 Wh cover a good part of a day, expandable to 5 kWh, and its 1000 W dual solar input recharges fast on site on a sunny day, without a generator's noise. At 12.5 kg, it moves easily from one spot to another. For very demanding tools or a full intensive day, aim for a higher-capacity station or the expansion.
Our team's recommendations based on the model's capacity, output power and weight.
Comparison
Around $946.45 the EcoFlow Delta 3 Plus compares to power stations of about 1 kWh, targeted by searches like "1000W power station" or "expandable portable battery". Here is how it stands against three references: the EcoFlow Delta 3 (its base version), the Anker SOLIX C1000 and the Bluetti AC180.
| Criterion | EcoFlow Delta 3 Plus | EcoFlow Delta 3 | Anker SOLIX C1000 | Bluetti AC180 |
|---|---|---|---|---|
| Capacity | 1024 Wh | 1024 Wh | 1056 Wh | 1152 Wh |
| AC output | 1800W (X-Boost 2400W) | 1800W (X-Boost 2400W) | 1800W | 1800W |
| Solar input | 1000 W (dual MPPT) | 500 W | 600 W | 500 W |
| USB-C max | 140 W | 100 W | 100 W | 100 W |
| Observed price | ≈ $946.45 | ≈ $878.75 | ≈ $924.78 | ≈ $809.69 |
In short, the Delta 3 Plus stands out with its dual 1000 W solar input (the fastest of the group), its 140 W USB-C ports and its NAS/HID-compatible inverter, advantages that neither the base Delta 3 nor the Anker or Bluetti match. Versus the Delta 3, it charges about $67.70 more for these three features: worth it if you recharge via solar, use a powerful laptop or protect a NAS, superfluous for more basic use. It is the best 1 kWh Delta 3 for a connected office or a solar setup.

Our tester's review: Christophe Delpuech
We compared the Delta 3 Plus to the base Delta 3 over several weeks, and the premium justifies itself as soon as you use one of its three real new features. The dual solar input up to 1000 W is the most telling: with two panels, it recharges visibly faster than a single-input station, a real plus in a van or a second home. The 140 W USB-C ports charge our laptops at full speed, without going through the mains brick. And above all, the inverter's NAS and HID compatibility kept our storage server and its software UPS perfectly stable during our outage tests, where a classic station might have cut the NAS. Otherwise, you get everything that makes the Delta 3 strong: 1024 Wh, 1800 W (2400 W X-Boost), 56-minute recharge and expansion to 5 kWh. One useful point: it is no heavier than the Delta 3, 12.5 kg in both cases, so the premium costs nothing in bulk. The one real caveat: if you use neither fast solar, nor the 140 W, nor the NAS, the base Delta 3 is enough and costs less. But for a connected office or a solar setup, the Plus is the right choice.

Both share 1024 Wh, 1800 W and one expansion port. The Delta 3 Plus adds a dual solar input of up to 1000 W across two regulators (against 500 W on a single one), USB-C ports at 140 W (against 100 W) and NAS and HID support, for around 100 pounds more.
Yes. Its dual solar input, up to 1000 W split across two MPPT controllers, recharges about twice as fast as a single 500 W input, a real asset in a van, a second home or off-grid.
Yes, but not to 5 kWh with just any battery. The Delta 3 Plus has a single expansion port: with a 1024 Wh Delta 3 add-on battery it reaches 2048 Wh. The advertised 5120 Wh requires a 4096 Wh Delta Pro 3 battery, which is far more expensive and far heavier.
Yes, it is one of its assets. Its advanced inverter switches over in under 10 ms and supports the NAS and HID protocols, keeping a network storage server and its peripherals running without an abrupt shutdown, avoiding data corruption.
