DELTA Gen4 stretches backup power for the fridge
Both DELTA models cut their own power draw by up to 70%, according to EcoFlow. They use 14W with AC on and no load, and 3W in standby. EcoFlow says industry averages are over 20W and 10W. A Fridge Runtime Boost feature reduces wasted energy between refrigerator cooling cycles. EcoFlow says that helps keep food cold for two to three days.
