Differences EcoFlow Delta 2 vs EcoFlow River 2 Pro
Below is a summary of the specifications:
Battery Capacity and Expandability
The EcoFlow Delta 2 has a larger battery capacity of 1,024Wh, which can be expanded up to 3,000Wh with additional battery packs. This makes it a versatile option for home backup, RV trips, and longer off-grid adventures.
The EcoFlow River 2 Pro, in contrast, features a 768Wh battery, which is smaller but still suitable for weekend camping, travel, and basic power needs. However, it does not support battery expansion, which limits its usability for extended off-grid power needs.
Winner: EcoFlow Delta 2
With higher capacity and expandability, the Delta 2 is the clear winner for users needing extended runtime.
Power Output and Device Compatibility
A power station’s wattage output determines what devices it can run.
The EcoFlow Delta 2 delivers 1,800W continuous output with a 2,400W surge capacity, making it capable of running high-power appliances like refrigerators, power tools, microwaves, and coffee makers.
The EcoFlow River 2 Pro has an 800W continuous output and a 1,600W surge capacity, which is sufficient for laptops, small kitchen appliances, lights, and mini-fridges, but it struggles with heavy-duty appliances.
Winner: EcoFlow Delta 2
With more than double the power output, the Delta 2 is better for demanding appliances and home backup use.
Charging Speed and Solar Input
Both models feature EcoFlow’s X-Stream fast charging, making them some of the fastest-charging power stations on the market.
The EcoFlow Delta 2 supports up to 500W of solar input, allowing it to fully recharge in about 3 hours with solar panels. It also charges fully in 1.3 hours using AC power.

Winner: EcoFlow Delta 2
With higher solar input and equally fast AC charging, the Delta 2 is a better choice for solar users and off-grid applications.
Portability and Weight
For users prioritizing portability, the EcoFlow River 2 Pro is lighter at 17.2 lbs (7.8 kg), making it easier to carry on camping trips and outdoor adventures.
The EcoFlow Delta 2 weighs 27 lbs (12 kg), making it heavier but still manageable for transport.
Winner: EcoFlow River 2 Pro
For ultra-portability and travel convenience, the River 2 Pro is the better option.
