The EcoFlow DELTA 2 portable power station is a highly capable and powerful solution for those who need reliable backup power on the go. With a battery capacity of 1024Wh and peak inverter output of up to 1800W, the DELTA 2 can power a variety of IT hardware and small clusters for a period of time. One of the biggest changes though for the 2nd generation DELTA series is the move to LiFePO4 battery technology, which has a much longer lifespan than prior chemistries.
