[0002] A mobile power bank or mobile charger is a portable charger that can be carried by an individual and can store electrical energy. It is mainly used to charge consumer electronic products such as handheld mobile devices. It is especially used in situations where there is no external power supply. Its main components include: a battery for storing electrical energy and a circuit for stabilizing the output voltage. Most mobile power banks come with a charger to charge the built-in battery. When the mobile power bank is actually used, water outside it often enters the interior through the charging port and causes a short circuit.
