Power & Performance
The EcoFlow Delta Pro delivers a massive 3600W of continuous AC output, nearly 50% more than the Delta 2 Max’s 2400W. It also supports surges up to 7200W, making it better for heavy-duty appliances like HVAC units or welders. The Delta 2 Max still handles essentials like refrigerators, microwaves, and power tools comfortably but isn’t designed for whole-home loads.
Battery Capacity & Cycle Life

from: EcoFlow
With a 3600Wh base capacity, the Delta Pro doubles the storage of the Delta 2 Max. It’s also expandable up to 25kWh with additional batteries and Smart Home Panel integration. The Delta 2 Max starts at 2048Wh and scales to 6144Wh—plenty for weekend use, but less ideal for long outages or off-grid homes. Both use long-lasting LiFePO4 cells with over 3000 cycles to 80% capacity.
Output Ports & Expandability
Both models offer 15 output ports, including multiple AC, USB-A, USB-C (100W), and DC car outlets. The Delta Pro has a 30A Anderson RV port and supports 240V output via the Double Voltage Hub, making it suitable for more demanding electrical systems. The Delta 2 Max lacks 240V capability but still supports dual extra batteries.
Portability & Weight
At 99 lbs with wheels and a telescoping handle, the Delta Pro is more like a portable power cart. The Delta 2 Max is a true portable unit at 50 lbs—easier for solo users to carry and move around, especially for vanlife or camping.
Charging Options

from: EcoFlow
Both models offer multiple charging options: AC wall charging, solar (with MPPT), car charging, and EcoFlow’s Smart Generator. The Delta Pro charges faster via 240V EV outlets (up to 3000W) and supports grid-tied charging with the EcoFlow Smart Home Panel. The Delta 2 Max is fast via AC (0–80% in ~65 minutes) but limited to 1000W solar input.
Price & Value
The Delta Pro commands a premium at around $3,699 but offers far more scalability, power output, and home integration. The Delta 2 Max sits closer to $1,899 and delivers excellent performance for most users who don’t need 240V or massive capacity. It’s one of the best mid-range solar generators under 60 lbs.
Final Verdict
- Choose the EcoFlow Delta Pro if you need whole-home backup, RV integration, 240V appliances, or long-term off-grid living.
- Choose the EcoFlow Delta 2 Max if you want a lighter, more affordable system for road trips, weekend camping, or basic home backup.
For most users, the Delta 2 Max is the more portable and practical choice. But for serious power needs, the Delta Pro is hard to beat.
FAQs
