Side by Side Comparison

Detailed Feature Comparisons

Design and Construction: The Delta 2 Max is larger and heavier due to its expanded capacity, making it less portable but more durable for home backup setups. The Delta 2 is compact and easier to carry, ideal for camping and quick outdoor use.

Battery Capacity: The Delta 2 Max holds 2048Wh, which can run appliances like refrigerators for hours, while the Delta 2 offers 1024Wh suited for smaller devices and short trips. The extra storage in the Max makes it better for extended outages.

AC Output: The Delta 2 Max supports 2400W continuous output, allowing it to power multiple heavy-duty appliances. In contrast, the Delta 2 peaks at 1800W, suitable for laptops, TVs, and smaller kitchen devices.

Expandability: With the Max, users can extend capacity up to 6kWh by adding extra batteries, while the Delta 2 caps expansion at 3kWh. This makes the Max better for users who may scale up their needs in the future.

Charging Speed: Both models support fast charging, but the Delta 2 Max takes longer to recharge because of its larger battery. However, its ability to handle higher solar input makes it more efficient for off-grid setups.

Solar Compatibility: The Max accepts up to 1000W solar input, doubling the Delta 2’s 500W limit. This gives it a strong advantage for outdoor enthusiasts or households aiming for renewable backup power.

Cycle Life: Both use LFP chemistry with over 3000 cycles before capacity drops significantly, ensuring long-term use with consistent reliability.

Portability: The Delta 2 is far easier to move around thanks to its lighter design. The Max, while more powerful, is better left in a fixed spot like a cabin or home emergency station.

Smart Features: Both units connect to the EcoFlow app, letting users monitor charging, usage, and firmware updates from a phone.
