What is Power bank? Power bank also called "mobile battery", "external battery", "spare battery", "digital charging companion", and "charging stick". It also has a very personal name: "mobile phone lover". "Power bank" concept has been developed along with the rapid growth and popularization of digital products, and its definition is: portable power supply which is easy to carry with large capacity.
In the light of the growing diversity of digital products features, more frequent usage, as well as closer and closer work association with our daily life, the problems how to increase the use time of digital products and electronic products, how to facilitate human living, how to add power supply, and how to play its full role have no time to delay. Power bank, is the best solution designed to address these problems. Carrying a mobile power can achieve outside charging for a variety of digital products anytime, anywhere.
Power banks quality depend largely on the quality of both batteries and protection board. High quality battery cells are the basis of mobile power life. The normal lithium polymer batteries have a longer life expectancy than 18,650 cylindrical lithium ion batteries, and their security risk is relatively low. The former one normally can be used for two or three years. Mobile power bank circuit board can be treated as a control system, which is mainly responsible for power distribution and transformation. It converts the voltage provided by lithium batteries into the standard voltage to provide electricity for charging device. Good Protection board has a conversion rate of up to 90%, while a general one has 80 ~ 85% and a bad one has only 70%. It the conversion rate is less than 80%, it means that the power bank suffers large line loss, and the battery cell itself suffers large calorific value.
What is Power bank? Power Bank is called mobile power pack for short, also called "mobile battery", "external battery", "spare battery", and "travel charger".
Power bank first appeared in 2001 on the CES Exhibition. At that time there was just a small booth at the CES Sand Museum. An oversea student pieced several AA batteries together with a control circuit. This small thing, because it can charge the digital products in no place, attracted the attention of many exhibitors. After found by the spies, many businessmen followed suit. It seemed like they would big play this new products. Mobile power concept was developed as the 2012 rapid growth and development of digital products. From 2012, digital products features have become more and more various and have been used more frequently. So how to improve digital products use of time, and how to play their full role are important. Having a power bank, people can charge various types digital products whenever and wherever possible.
