EcoFlow DELTA Pro review: what stands out?
The DELTA Pro stands out for its 3600Wh LFP capacity, 3600W AC output and expansion to 25kWh with compatible equipment. Five AC outlets and several USB, DC and car outputs provide options for different devices.
EF ECOFLOW Portable Power Station 3600Wh DELTA: Best for expandable home backup
- 3600Wh LFP battery
- 3600W AC output
- Expandable to 25kWh
- 5 AC outlets
A large-capacity power station with 3600W AC output, app control and several charging paths. Expansion can raise capacity to 25kWh with compatible extra batteries or Smart Generators.
Pros
- 3600Wh LFP battery capacity
- Capacity expands up to 25kWh
- Five AC outlets and multiple USB and DC ports
- Five charging methods
Cons
- 99 lb weight makes moving it a two-person planning task
- Expansion depends on compatible add-ons
- High output does not mean every appliance can run at once
Its app works over Wi-Fi or Bluetooth and can show charge level, temperature and charge or discharge times. The app also offers controls for settings such as battery life and input or output.
Those features make the unit flexible, but they don't tell you how long it will run a particular load. Runtime depends on the appliance and the power it draws, so estimate your needs before relying on it for an outage.
When does the original EcoFlow DELTA Pro make sense?
Choose the original when its 3600Wh capacity and 3600W AC output match your planned loads, and you value the option to expand later. It can make sense for a home backup setup that also needs to supply power outdoors.
Consider other models if you need a higher stated capacity or 240V support. The EcoFlow DELTA 3 Ultra review and EcoFlow DELTA 3 Max review can help you compare newer options.
What do 3600Wh and 3600W mean in practice?
3600Wh describes stored energy, while 3600W describes the DELTA Pro's AC output rating. The first helps you estimate how much energy is available; the second helps you assess whether a device can draw power from the station.
For a rough runtime estimate, divide usable watt-hours by the device's average watt draw. Real runtime can be lower due to conversion losses, device cycling and other loads, so treat the estimate as a planning aid.
Check both running power and startup power for appliances with motors or compressors. Then add the loads you'll run together and compare that total with the station's AC output.
EcoFlow says X-Boost can raise output to 4500W. It also says two DELTA Pro units can pair for 7200W, but that setup requires another unit and should be planned around the specific loads and connections you need.
For a broader look at comparable high-output options, see our guide to the best EcoFlow power stations for 2000W loads.
How does the DELTA Pro handle expansion and charging?
The DELTA Pro can expand from 3.6kWh to 25kWh with DELTA Pro Extra Batteries or Smart Generators. It supports EV station, solar, wall outlet, Smart Generator and car outlet charging.
EcoFlow gives example charging times of 1.8 hours from a 240V outlet at 3000W, 2.7 hours from an 1800W wall outlet and 2.8 hours with four 400W solar panels. Those times apply to the stated inputs and setup, so don't assume every outlet or panel arrangement will recharge it at the same rate.
Expansion may help if your backup plan includes longer outages or more loads, but it adds equipment to buy, store and connect. Start by listing the devices you want to keep running and how long you need them powered.

Is the DELTA Pro solar bundle worth considering?
The solar bundle pairs the DELTA Pro with a 400W foldable panel. It's a straightforward option if you want a panel included and expect to use solar charging, though the panel and station arrive in separate packages.
EF ECOFLOW Solar Generator 3.6KWh DELTA Pro: Best for a panel included
- 3600Wh DELTA Pro
- 400W portable solar panel
- 15 outputs
- App control
This bundle pairs the DELTA Pro with a 400W foldable solar panel, so it suits buyers who want solar charging equipment in the same package. The station and panel arrive separately.
Pros
- Includes a 400W foldable panel
- DELTA Pro has 15 outputs
- Panel has an adjustable carry case
- App control over Wi-Fi or Bluetooth
Cons
- Panel and station arrive in separate packages
- A single panel takes longer to recharge than multiple panels
- Station weighs 99 lb
EcoFlow states that one 400W panel can recharge the station in 11 hours, while three 400W panels take 3.5 hours. Actual solar input depends on conditions and setup, so plan for variable sunlight and allow time beyond the stated examples.
The panel weighs 16kg (35.3 lb), has an adjustable carry case and is rated IP68 for dust and water protection. That makes portability part of the bundle, but the station itself remains a 99 lb unit.
If you already own compatible solar panels, compare their output and connections with the DELTA Pro before choosing a bundle. If you don't, consider whether you have a suitable area to place and reposition the panel.
How does the DELTA Pro compare with the DELTA Pro 3?
The DELTA Pro 3 offers 4096Wh capacity, 4000W output and 120V/240V support, while the original DELTA Pro has 3600Wh capacity and 3600W AC output. The Pro 3 also weighs 115 lb, compared with 99 lb for the original.
EF ECOFLOW DELTA Pro 3 Portable Power: Best for higher capacity and 240V
- 4096Wh LFP battery
- 4000W AC output
- 120V and 240V support
- Expandable to 48kWh
The DELTA Pro 3 raises capacity and output, supports 120V and 240V, and can expand to 48kWh with extra batteries or Smart Generators. It is heavier than the original DELTA Pro.
Pros
- 4096Wh LFP battery capacity
- 120V and 240V support
- Expandable up to 48kWh
- Seven unique and 18 combo charging methods
Cons
- 115 lb weight
- Expansion requires compatible add-ons
- Higher output does not remove the need to check appliance starting and running loads
The DELTA Pro 3 can expand to 48kWh with extra batteries or Smart Generators. It has seven unique and 18 combo charging methods, according to EcoFlow, and supports X-Boost up to 6000W.
Those higher figures may matter if your setup needs more stored energy or 240V support. They don't automatically make it a better fit: check the appliance requirements, space and moving plan, then compare the capacity you expect to use.

What practical trade-offs should you weigh?
The DELTA Pro's 99 lb weight is a key ownership trade-off. It may be manageable when the unit stays in one planned location, but less convenient if you need to carry it between a vehicle, campsite or storage space.
Measure doorways and the place where you plan to keep it. Think through how you'll move the unit safely before an outage, rather than during one.
Capacity expansion is another planning choice. Extra batteries or Smart Generators can increase capacity, but they require compatible equipment, storage space and a clear setup plan.
Finally, match output to actual loads. A high wattage rating doesn't mean every appliance can run together or that the station will run them for a full day.
Add up likely simultaneous loads and estimate runtime before you decide.
Is the EcoFlow DELTA Pro worth it?
The EcoFlow DELTA Pro is a strong fit when you need 3600Wh, 3600W AC output, several charging options and room to expand. It is less convenient when you need a lighter station for frequent carrying or a higher-capacity setup out of the box.
Pick the original DELTA Pro if its output and expansion path cover your plan. Choose the solar bundle if you also want a 400W panel, or compare the DELTA Pro 3 if 120V/240V support and its higher capacity fit your loads.
