This is normal if the heat is within safe limits.
1. Cable/plug: Slight warmth is normal due to current flow. Surface temperature below 60°C is within the normal range. Make sure the cable is fully inserted and avoid charging on very bumpy roads.
2. Portable power station: The exterior may feel warm during charging. Surface temperature below 60°C is safe.
