EcoFlow is best known for portable power stations: big rechargeable batteries with household outlets that can run a fridge, a laptop or a CPAP machine during a blackout or on a camping trip. The brand also makes a dual fuel Smart Generator that runs on gasoline or propane and is designed to recharge its largest power stations, so you can keep the lights on for days rather than hours. If you searched for an EcoFlow gas generator, the key thing to understand is that EcoFlow’s generator is built to pair with a battery, not replace it.
The six options below range from the generator on its own, to a DELTA Pro 3 bundle with the generator included, to battery-only power stations from the large DELTA Pro down to the compact DELTA 3 Classic and its solar kit.

EF ECOFLOW 3200W DC Fast Charging
Best for: DELTA Pro or Pro 3 owners
Pros
- Gasoline or propane fuel
- 3200W DC fast charging
- CO and oil alerts with auto shutdown
- 3-year warranty
Cons
- Works only with DELTA Pro models
- Needs firmware update to pair
The EF ECOFLOW 3200W DC Fast Charging Dual Fuel Smart Generator is EcoFlow’s gas generator. It burns gasoline or LPG (propane), and rather than simply offering outlets like a traditional generator, it is designed to send up to 3200W of DC power straight into a compatible power station. EcoFlow says this saves 40% of fuel when fully charging the DELTA Pro 3, which it describes as about 1kWh more power per gallon. A 20 lb propane tank provides up to 24kWh of power, and one full gasoline tank produces 8kWh, according to the listing.
Starting and stopping is made simple with 7 start and 6 shutdown methods, plus four automatic start modes: customizable start, night-care mode, PV-priority mode (which lets solar go first) and smart reverse charging, which starts the generator when the battery runs low. The EcoFlow app shows real-time alerts for carbon monoxide levels, high and low temperatures, engine oil and overloads, and all of these except fuel alerts trigger automatic shutdown. It has a 4-stroke engine, a 4-liter tank, electronic ignition and 8 outlets, with a 3-year warranty.
Very important: the listing states the Smart Generator is currently compatible only with the DELTA Pro 3 and the original DELTA Pro, and both need the latest firmware. It suits people who already own one of those. If you are buying everything new, the bundle below is simpler. As with any fuel-burning generator, run it outdoors only.
EF ECOFLOW 4096Wh Delta Pro 3 with Dual Fuel Generator for Whole-Home Backup

EF ECOFLOW 4096Wh Delta Pro 3 Power Station With 3200W Dual Fuel Generator
Price and specifications are read from the Amazon product page and can change.
EF ECOFLOW 4096Wh Delta Pro 3
Best for: Whole-home backup from scratch
Pros
- 4096Wh LFP battery
- Expandable to 48kWh
- Dual fuel generator included
- 240V output
Cons
- Ships in two separate packages
- Engine type listed inconsistently
The EF ECOFLOW 4096Wh Delta Pro 3 bundle is the EcoFlow DELTA Pro 3 with generator in one purchase. The power station has a 4096Wh LFP battery (LFP, or lithium iron phosphate, is a long-lasting, stable battery chemistry), expandable to 48kWh with extra batteries or Smart Generators. EcoFlow says this can provide 2 to 4 days of whole-home backup. It lists 4000W output and 240V, which matters because some larger home appliances run on 240V.
The DELTA Pro 3 lists 7 charging methods and 18 combinations, including wall outlets, solar panels, gas generators and EV charging piles. The included dual fuel generator carries the same gasoline and propane figures and safety alerts described above. The station and the generator arrive in separate packages. One oddity: the bundle specs list a 2-stroke engine, while the generator’s own listing says 4-stroke, so rely on the generator listing for engine details.
This bundle suits homeowners planning serious outage backup with no existing EcoFlow gear. For a smaller home or apartment, the DELTA 3 Max is far more manageable.
EF ECOFLOW Portable Power Station 3600Wh DELTA Pro for Flexible Charging
Best for: Protecting computers and small appliances
Pros
- 0-80% in 45 minutes
- Under 10ms UPS switchover
- 1024Wh LiFePO4 battery
Cons
- Not expandable with listed extra batteries
- Solar panel sold separately

EF ECOFLOW Portable Power Station 3600Wh DELTA Pro, 120V 3600W AC Output
Price and specifications are read from the Amazon product page and can change.
EF ECOFLOW Portable Power Station 3600Wh
Best for: Home backup plus EV-station charging
Pros
- 3600Wh LFP battery
- Up to 4500W with X-Boost
- 15 output methods
- Charges from EV stations
Cons
- Generator sold separately
- Pairing two units needed for 7200W
The EF ECOFLOW Portable Power Station 3600Wh is the original EcoFlow DELTA Pro. It has a 3600Wh LFP battery that can grow from 3.6kWh up to 25kWh with extra batteries or Smart Generators, and 3600W of AC output that X-Boost can stretch to 4500W. X-Boost is EcoFlow’s way of running some higher-wattage devices by gently lowering voltage. Two units can be paired for 7200W.
It offers 15 output methods and five ways to charge: EV charging stations, solar, wall outlets, the Smart Generator and a car outlet. EcoFlow lists a full recharge in 1.8 hours on a 240V outlet at 3000W, 2.7 hours on an 1800W wall outlet or 2.8 hours with four 400W solar panels. The app works over Wi-Fi or Bluetooth for monitoring charge level, temperature and timing.
The DELTA Pro suits buyers who want generator compatibility without buying the newest model. If you want a lighter unit for road trips, the DELTA 3 Max is smaller. For comparison with other large battery units, our guide to the portable power station category covers more options.
EF ECOFLOW DELTA 3 Max Portable for RVs and Mid-Size Backup

EF ECOFLOW DELTA 3 Max Portable Power Station, 2048Wh LFP Battery, 2400W
Price and specifications are read from the Amazon product page and can change.
EF ECOFLOW DELTA 3 Max Portable
Best for: RV trips and mid-size home backup
Pros
- 2048Wh LiFePO4 battery
- 3400W X-Boost output
- 0-80% in 1.13 hours
- Under 10ms transfer time
Cons
- Generator pairing not confirmed
- Outlet count listed unclearly
The EF ECOFLOW DELTA 3 Max Portable power station, the EcoFlow DELTA 3 Max, has a 2048Wh LiFePO4 battery rated for 10 years of daily use and 2400W of output, with up to 3400W in X-Boost mode. EcoFlow says it can run fridges, microwaves and power tools.
It recharges from 0 to 80% in about 1.13 hours with X-Stream fast charging, and switches to battery in under 10ms during an outage, which is fast enough to keep a computer running without a restart. The listing also highlights ultra-quiet operation, a lighter build for carrying between home and an RV, and app control for scheduling charging and setting priorities. Some spec fields are unclear, such as “Total Power Outlets: 3” and “Runtime: 10 hours” without context, and the listing does not confirm Smart Generator compatibility, so do not plan on pairing it with the dual fuel generator.
This suits families who want solid blackout backup and weekend RV power. If you mainly protect a desk setup, the DELTA 3 Classic is smaller.
EF ECOFLOW Portable Power Station Delta 3 Classic for Everyday Essentials
The EF ECOFLOW Portable Power Station Delta 3 Classic is the compact entry into the lineup, a 1024Wh unit with 1800W output, 3600W surge and up to 2600W with X-Boost. It charges from 0 to 80% in 45 minutes on AC power and in about 2.5 hours from an optional 500W solar panel.
Its under-10ms UPS feature (an uninterruptible power supply that switches over instantly) protects PCs and medical devices. It uses LiFePO4 cells rated for 10+ years of daily use and a smart battery management system, and the app offers modes like Storm Alert and Self-Powered Mode. The listing notes it is not compatible with the DELTA 2 or DELTA 3 Series Smart Extra Batteries, so its capacity cannot grow with those.
This suits apartments, home offices and campers who need a fridge or laptop running for a while. If you need days of power, look to the DELTA Pro models.
EF ECOFLOW Solar Generator Delta 3 Classic with 220W Panel for Off-Grid Trips
Best for: Campers wanting solar in one box
Pros
- 220W bifacial panel included
- Up to 25% panel efficiency
- 1800W output, 3600W surge
Cons
- 8 hours to solar charge
- Panel and station ship separately
The EF ECOFLOW Solar Generator Delta 3 Classic kit pairs the same 1024Wh station with a 220W bifacial solar panel. An EcoFlow solar generator is simply a power station plus panels: no fuel, no fumes. The panel uses N-Type cells with up to 25% conversion efficiency, and bifacial means it can collect light from both sides.
With this panel, EcoFlow lists a full recharge in about 5.8 hours of sun. You get the same 1800W output, 3600W surge, 45-minute 0 to 80% AC charging, under-10ms UPS and LiFePO4 cells. The station measures 7.9 x 11.1 x 15.7 inches. The two items ship separately.
This suits campers and gift buyers who want a ready-made solar kit. For more on sun-powered setups, see our guide to the solar generator category.
How to Choose the Right EcoFlow Gas Generator Setup
Battery first, generator second. The power station stores electricity and runs your devices quietly indoors. The dual fuel generator refills that battery from outside. You need both only for multi-day outages.
Check compatibility. The Smart Generator lists only the DELTA Pro 3 and DELTA Pro. If you want a generator in your plan, choose one of those.
Match capacity to needs. Watt-hours (Wh) tell you how much energy is stored; watts (W) tell you how much it can deliver at once. A 1024Wh unit covers essentials for a short time, 2048Wh handles more, and 3600 to 4096Wh is home-backup territory.
Solar or fuel. Solar is silent and free once installed but depends on weather. Propane stores well for emergencies, and the generator gives up to 24kWh from a 20 lb tank.
FAQ
Which EcoFlow should I buy?
For whole-home backup, the DELTA Pro 3 bundle. For an existing DELTA Pro, the Smart Generator alone. For RVs, the DELTA 3 Max. For desks and camping, the DELTA 3 Classic or its solar kit.
Can the Smart Generator charge a DELTA 3 Max or Classic?
The generator listing names only the DELTA Pro 3 and DELTA Pro as compatible, so the listings do not support pairing it with the DELTA 3 models.
What fuel does the EcoFlow dual fuel generator use?
Gasoline or LPG (propane). A full gasoline tank gives 8kWh, and a 20 lb propane tank gives up to 24kWh.
Is the EcoFlow generator safe to use?
It lists carbon monoxide, temperature, oil and overload alerts with automatic shutdown. Like all fuel generators, use it only outdoors, away from windows.
What does LFP or LiFePO4 mean?
Both are names for lithium iron phosphate, a battery chemistry known for long life and stability. Every EcoFlow station here uses it.
