According to recent news, the portable power supplies with lithium-ion cells are of different security properties. Therefore, some users are worried if laptop charger is secure enough in the process of work.
As to the derivative instruments, portable power supply has three kinds of specifications, including polymer Li-ion battery, Ni-cd and Ni-mh batteries. Since 2009, many more portable chargers are available to mobile phone, digital camera, vidicon, DVD, PDA, and other consumer electronics.
The primary work principle for portable power supply is related to store and transfer power energy. Therefore, we can regard it as a larger lithium-ion battery of small portable laptop charger, larger capacity and more convenient in carrying, performance, capacity and portability.
Compared to original versions, they are cheaper and more suitable to businessmen, young man, travelers and others.
Compared to Ni-mh and Ni-cd batteries, this kind of portable power supply is actually of lower cost while many manufacturers are working hard to improve the product competitiveness in price and quality.
However, recently some news is about the accidents of laptop charger and battery that they run into explosion. Normally, the lithium-ion cells nowadays belong to liquid lithium-ion battery. According to different specifications, these batteries are also of different size. Therefore, under different work situations, they will perform different from each other in internal pressure, work temperature and so on. In some cases, these chargers are possible to be powerful enough as a bomblet.
Therefore, users need to check the internal structure and industrial certification when selecting portable power supplies for laptop, camera, mobile phone and other electronics to avoid overloading, overheating, short circuit and other damages.
