First, you should consider your needs for purchasing a power station and for running what kind of equipment.
Secondly, you need to know the power of this equipment and whether the model can run your equipment and meet your needs.
Generally, there will be voltage and current specified on the body of household electrical equipment. You need to determine whether the voltage is within the allowable range of model. If it is, you can use this information to calculate the power of your equipment and determine whether the model can run all the equipment you require.

All of our power stations are equipped with a Battery Management System (BMS) to prevent them from overcharging. To maintain and prolong the health of the battery, we do suggest unplugging the unit from the charger after the battery has reached 100%.
If the battery is to be unused for a long time (more than 3 months), it should be maintained at 60-80% of the rated capacity (it’s recommended to check and charge every 3 months). Store it in a dry and cool place with temperature range between 0°C~40°C, and humidity 0%~60%. Avoid contact with corrosive substances, and far from fire and heat sources.
