Differences EcoFlow Delta 2 Max vs EcoFlow Delta Pro
Below is a summary of the specifications:
Battery Capacity and Expandability
When it comes to battery capacity, the EcoFlow Delta Pro is the undisputed winner. With a massive 3,600Wh LiFePO₄ battery, it offers nearly twice the base capacity of the Delta 2 Max (2,048Wh). Additionally, the Delta Pro can be expanded up to 25,000Wh by connecting extra EcoFlow Smart Batteries and the EcoFlow Smart Generator, making it a true whole-home backup system.
The EcoFlow Delta 2 Max features expandable battery support up to 6,144Wh, which is more than sufficient for RV users, campers, and moderate home backup needs. However, it cannot compete with the Delta Pro’s unmatched capacity and scalability.
Winner: EcoFlow Delta Pro
With a higher base capacity and significantly greater expandability, the Delta Pro is the superior choice for whole-home power backup and large-scale off-grid needs.

Power Output and Appliance Compatibility
The EcoFlow Delta Pro offers an impressive 3,600W continuous power output with a surge capacity of 7,200W, making it suitable for running high-wattage appliances such as refrigerators, air conditioners, electric stoves, and heavy power tools. Additionally, it supports 120V and 240V output, allowing it to power large appliances or even an entire home through the EcoFlow Smart Home Panel.
The EcoFlow Delta 2 Max, while still powerful, delivers 2,400W continuous output and 5,000W surge capacity, making it ideal for moderate energy needs such as charging electronics, powering small appliances, and running essential devices during power outages. However, it does not support 240V output, which limits its ability to run certain heavy-duty appliances.
Winner: EcoFlow Delta Pro
With higher continuous output, greater surge power, and 240V support, the Delta Pro is the best choice for powering high-wattage devices.
Solar Charging and Recharging Speed
Both models excel in fast recharging, but there are key differences.
The EcoFlow Delta 2 Max supports 1,000W of solar input, allowing it to fully charge in 2-3 hours under optimal sunlight conditions. Additionally, its AC charging speed is faster, recharging from 0 to 100% in just 1.1 to 1.6 hours using 2,400W AC input.
The EcoFlow Delta Pro supports a higher 1,600W solar input, meaning it recharges faster via solar panels, making it an excellent choice for extended off-grid living. However, its AC recharge speed is slightly slower, taking 1.8 to 2.3 hours due to its larger battery size.
Winner: Tie
- Delta 2 Max wins in AC recharge speed
- Delta Pro wins in solar efficiency

Portability and Design
Portability is another major factor when choosing between these two models.
The EcoFlow Delta 2 Max, weighing only 50 lbs (22.7 kg), is significantly lighter and easier to transport. It features integrated handles, making it ideal for RV trips, camping, and outdoor adventures.
The EcoFlow Delta Pro, at 99 lbs (45 kg), is twice as heavy. However, it compensates for this with built-in wheels and a telescopic handle, making it easier to maneuver despite its weight.
Winner: EcoFlow Delta 2 Max
For portability and ease of transport, the Delta 2 Max is the better option.
