Electric power personnel remind that the internal capacity of power strips with USB interfaces is limited, so the electronic components are very close together, which can easily affect each other and cause damage. If you frequently use incompatible mobile phone chargers and data cables, it is easy to cause poor contact with the phone, leading to electrical leakage and short circuits in the power strip.
