With the development of science and technology, solar fast wireless power bank has brought many conveniences to people's lives, but there are also some potential safety hazards during the charging process.
First, overheating is a common problem. During solar charging, if the light intensity is too high and the duration is long, and the heat dissipation system inside the mobile power bank is not well designed, the heat cannot be dissipated in time, which may cause the temperature of the battery and related circuit components to rise sharply. Excessive temperature will not only reduce the service life of the battery, but may also cause serious consequences such as battery bulging, leakage, and even explosion. During the wireless charging process, a certain amount of heat will also be generated due to energy conversion. If the wireless charging transmitter and receiver are not well matched or the heat dissipation is poor, local overheating will also occur.
Secondly, overcharging cannot be ignored. Whether it is solar charging or wired charging, if the charging management system of the mobile power bank has defects and cannot accurately monitor the battery power and automatically stop charging when it is full, the battery will continue to be in a charging state. Overcharging will increase the internal pressure of the battery, which may damage the structure of the battery, cause the battery performance to decline, and even cause safety accidents. In particular, some mobile power banks with poor quality may have an overcharge protection mechanism that is virtually non-existent.
In addition, short circuit risk is also a major hidden danger. In the charging circuit, if the positive and negative poles are short-circuited due to poor manufacturing process, circuit aging or external force damage, a huge current will be generated instantly. This may burn components in the charging circuit, such as fuses, control chips, etc. If the short circuit is not cut off in time, it may also cause serious consequences such as fire. For the wireless charging part, if its electromagnetic shielding measures are not in place, foreign metal foreign objects enter the charging area, which may cause electromagnetic induction anomalies and indirectly cause short circuits.
In addition, when charging with solar energy, if there is bad weather, such as thunder and lightning weather, the solar panel may be struck by lightning, and the strong lightning current may impact the mobile power bank along the charging line, causing devastating damage to its internal circuit and possibly endangering the safety of people using it around. In short, the safety hazards of solar fast wireless power bank during charging involve many aspects, which requires manufacturers to strictly control product quality and improve safety protection measures. At the same time, users must also correctly operate and maintain mobile power banks to reduce safety risks and protect themselves and their property.
