In most household electrical appliances, the grounding wire is used to prevent electric shock in the event of internal electrical leakage by connecting it to the outer casing.
However, Jackery portable power stations are designed with a highly insulated plastic enclosure, which significantly reduces the risk of electric shock.
Therefore, the grounding wire on the included AC charging cable does not need to be connected. Even without connecting the grounding wire, the portable power station can be used safely under normal conditions.
When charging from a household AC outlet, is it necessary to connect the grounding (earth) wire as stated in the user manual?
