To set up your EcoFlow Delta 3, simply unbox the unit and ensure it's fully charged before first use. Connect the included AC charging cable to a standard wall outlet. The power station will automatically begin its rapid charging process. For optimal performance, always charge in a well-ventilated area. The Delta 3 is compatible with a wide array of devices and appliances thanks to its diverse output ports, including multiple AC outlets. Its capacity is expandable with compatible EcoFlow extra batteries (sold separately), allowing you to scale your power storage from 1.5kWh up to 5.5kWh. For care, store the unit in a cool, dry place away from direct sunlight and extreme temperatures. It's recommended to discharge and recharge the battery every 3-6 months to maintain battery health if not in regular use. Clean the exterior with a soft, dry cloth. Do not expose the unit to water or harsh chemicals. Ensure all ports are free of dust and debris before use. Always refer to the user manual for detailed safety guidelines and specific operating instructions.
