The EcoFlow Delta 2 launched at $699 and has been a reference product in portable power stations since (recently, the price has been in the $430-$600 range). It is now $449 on Amazon, which is the largest percentage discount this station has seen since launch and puts a 1,800W, 15-outlet LiFePO4 power station below what gas generators with a fraction of the features cost at regular retail.

1,800W output, 15 outlets, and a full charge in 80 minutes
The Delta 2 delivers 1,800W of continuous AC output across 15 total outlets covering AC plugs, USB-C, USB-A, and DC ports, which handles a refrigerator, a fan, a router, lights, and device charging simultaneously without hitting the ceiling. EcoFlow’s X-Stream charging technology fills the 1,024Wh LiFePO4 battery from zero to 80% in 50 minutes and to full in 80 minutes via a standard wall outlet, which is seven times faster than conventional power station charging and means a full charge is practical even when time is short. Solar input accepts up to 500W of panel capacity for off-grid charging during camping, RV trips, or extended power outages.
The LiFePO4 battery chemistry is rated for 3,000-plus charge cycles while retaining 80% capacity, which EcoFlow translates to a 6-times-longer lifespan than standard lithium-ion power stations. The expandable design supports additional EcoFlow batteries that bring total capacity up to 3kWh, which covers more demanding home backup scenarios without replacing the base unit. The sophisticated battery management system monitors temperature, voltage, and current continuously to keep charging and discharging within safe parameters automatically.
