Getting started with your EcoFlow RIVER 3 is straightforward. To set up, simply plug the power station into a wall outlet using the provided AC charging cable to achieve a full charge in approximately one hour. For compatibility, the RIVER 3 can connect and power up to 5 appliances simultaneously through its various output ports (details on specific port types not provided, but generally include AC, USB, and DC outlets). When utilizing the X-Boost feature, ensure that the appliance's total wattage is within the 600W limit and that it's not a device with strict voltage requirements, such as sensitive medical equipment or certain heating elements. For care, the IP54 water-resistant battery pack offers protection against light rain and dust, but it should not be submerged in water. Always store the unit in a dry place, away from extreme temperatures. The 1-hour fast charging technology is designed to preserve battery health, allowing frequent charging without significant degradation.
