EcoFlow’s exclusive Storm Guard Mode monitors severe weather alerts and automatically triggers AC charging remotely using industry-leading X-Stream fast charging tech - so it can be ready long before a disaster hits.
• With the ability to recharge from fuel generators such as gas and propane units @ an 1800W input, recharge to 80% in just 68 mins. The EcoFlow Smart Generator 4000 (Dual Fuel) powers up the Delta 3 Max for storms, outages, and off grid living.
• Solar recharging is an obvious choice for this all new powerstation. Features a 500W Input, at max input charge from 0-80% in 3.43 hours. Pair it with EcoFlow Solar Panels (25% high-efficiency) for reliable power during camping trips, van life, or off-grid living. We would recommend 2x EcoFlow NextGen 220W Portable Solar Panels!
