You can even pair two units together to achieve 7200Wh. EcoFlow's X-Stream charging technology isn't just fast, it's safe too. The battery management system ensures safety and longevity while you fully charge DELTA Pro from a standard AC wall outlet in 1.8 hours, and you can also charge up at thousands of electric vehicle stations worldwide, or use solar panels or EcoFlow's optional Smart Generator.
