Table Caption: EcoFlow Delta Pro vs Delta 2 Specs Comparison
Power & Performance
The EcoFlow Delta Pro offers significantly more power with a 3600W inverter (7200W surge), compared to the Delta 2’s 1800W. This makes the Delta Pro suitable for high-demand appliances like electric dryers, HVAC units, and well pumps—ideal for off-grid homes or full backup scenarios.
The Delta 2, while less powerful, still handles most household devices like refrigerators, laptops, lights, and TVs with ease.
Battery Capacity & Cycle Life
EcoFlow DELTA 2 Portable Power Station
from: EcoFlow
Battery size is one of the biggest differences. The Delta 2 has a 1024Wh LiFePO4 battery, while the Delta Pro boasts a 3600Wh base capacity and can scale up to 25kWh with external batteries and smart panels.
Both use long-lasting LiFePO4 batteries, but the Delta Pro includes slightly better cycle life (3500+ cycles to 80% vs. Delta 2’s 3000+).
Output Ports & Expandability
The Delta Pro has more output options, including 240V support (when paired with a second unit), EV-grade outputs, and additional modular ports for EcoFlow’s Smart Home Panel. It’s built for expandability.
The Delta 2 has fewer ports but includes six 1800W-rated AC outlets, which is still excellent for a mid-size unit.
Portability & Weight
Here’s where the Delta 2 shines: it’s just 27 lbs, making it easy to carry, travel with, or store in a van or closet.
The Delta Pro, at 99 lbs, is heavy but includes wheels and a suitcase-style handle for mobility.
If you need true portability, the Delta 2 wins. If you want maximum backup power, the Delta Pro justifies the weight.
Charging Options
Both units offer fast AC and solar charging, but the Delta Pro has far more flexibility. It supports:
- EV station charging
- Smart Generator integration
- 1600W solar input
- Up to 6500W combined input (AC + solar + EV)
The Delta 2 maxes out at 500W solar input and 1200W AC charging. Fast, but not nearly as versatile.
Price & Value
The EcoFlow Delta 2 retails around $999 and often sells for less. For most users needing 1kWh of backup or a portable RV/van option, it’s one of the best-value stations on the market.
The Delta Pro costs about $3,599 but delivers industrial-level power and expandability. For whole-home backup or long-term off-grid setups, it’s worth the premium.
Final Verdict
- Choose the EcoFlow Delta 2 if you want an affordable, portable, and powerful unit for everyday use, camping, or light backup.
- Choose the EcoFlow Delta Pro if you need serious power for home backup, off-grid living, or large-scale solar setups.
Both are excellent, but they serve different roles.
FAQs
Can the Delta 2 power a refrigerator during an outage?
Yes. With its 1024Wh capacity and 1800W output, it can run a standard refrigerator for 6–12 hours depending on usage.
Is the Delta Pro overkill for most users?
For basic needs, yes. But for off-grid cabins, RVs with AC, or full-home solar integration, it’s one of the best options available.
Can either unit be charged with solar panels?
Yes. Both support solar input, though the Delta Pro accepts up to 1600W, while the Delta 2 is limited to 500W.
Does the EcoFlow app work with both models?
Yes. Both offer app connectivity via WiFi and Bluetooth for remote monitoring and control.
