Yes. Jackery power stations can be used outdoors. However, most Jackery portable power stations are not waterproof, as the outlets and ventilation ports are exposed and should be kept away from water.
The 1500Ultra, has a higher level of water resistance compared to other models. When the input and output ports are covered, all sides except the bottom cooling fan are protected against water exposure.
To avoid damage, we do not recommend using the power station in rainy or wet conditions. Always keep the unit dry and protected from water exposure.
