EcoFlow DELTA 2 1024Wh is a portable power station built around a 1,024Wh LiFePO4 battery, six AC outlets, and a continuous 1,800W output. The US model is identified as ZMR330-US, giving the unit a precise place in EcoFlow's DELTA lineup.

Capacity And Output

The unit stores 1,024Wh at 51.2V and uses lithium iron phosphate cells. Its AC section supplies 1,800W through six outlets, while surge output reaches 2,700W for short demand spikes.

EcoFlow lists a 27-pound net weight and dimensions of 15.7 by 8.3 by 11.1 inches. Those figures put the DELTA 2 below the weight of many larger backup batteries, although the enclosure still requires two-handed carrying when loaded into a vehicle or storage area.

Charging And Connections

AC charging reaches 80 percent in 50 minutes and 100 percent in 80 minutes under the published charging specification. Solar input accepts up to 500W, while the car input supports 12V and 24V batteries.

The connection layout includes two USB-A ports rated at 12W each, two USB-C ports rated up to 100W each, two DC5521 outputs, and one car outlet rated at 126W. Wi-Fi and Bluetooth allow settings and status monitoring through the EcoFlow app.

Expansion And Longevity

EcoFlow states that the DELTA 2 can expand to 2,048Wh with the DELTA 2 Extra Battery and to 3,040Wh with the DELTA Max Extra Battery. The expansion figures apply to compatible EcoFlow batteries rather than to the base unit alone.

The LFP battery is rated for 3,000 cycles to 80 percent or more of its original capacity in EcoFlow's published comparison information. The manufacturer also lists a five-year warranty for the DELTA 2, which is longer than the two-year coverage shown for some competing portable power stations.

Use Case And Limits

At $999.00 in the Best Buy listing dated 01/17/2025, the DELTA 2 sits in the higher-capacity portable power station class. Its 1,800W output suits refrigerators, networking equipment, lights, chargers, and other appliances within that limit.

The 27-pound enclosure favors stationary backup, car camping, and short-distance transport over extended carrying. Compared with smaller power stations, it offers more outlets and higher output; compared with larger systems, its 1,024Wh capacity limits runtime for high-wattage appliances.
