Struggled with which clothes for the work when you open the closet in the morning? what for lunch? Or when you go out, there is “Battery low” suddenly pop up on the system notification? I believe that for most heavy users of mobile phone, the last one is the most pressing worry. With the popularization of power bank, the power anxiety has begun to ease.
Who invented the first power bank in the world? What does it look like? Today, we are going to talk about the growth of the power bank.
At the CES exhibit in 2001, a student displayed the earliest conceptual product of power bank at a booth (similar to street vendor) in the beach pavilion. He put several AA batteries together by controlling the circuit and used it for charging other digital equipment. At that time, this humble thing attracted the attention of many exhibitors as it could charge the digital products anywhere.
1 .Sprout period
Power bank first appeared in 2001, but it was more like a new hype of the time due to those factors: the cycle life of the battery was insufficient, the volume was large and the manufacture technology on battery remained immature; people used the mobile phones with single function in daily life that the battery life could be last for 3 to 4 days, so the demand was lowest; and there was no real market for the power bank when the market for cellphone was not universal.
Until iPhone came along, bring the revolution in mobile phone. The mobile phone was slimmer and more powerful. Internet, gaming, taking pictures and other functions were all contained in a small mobile phone. Meanwhile, it possessed a large touchscreen. Such multifunctionality had inevitably led to an increase in power consumption. Logically speaking, iPhone should be equipped with a larger battery, but Apple configured a built-in non-detachable and tiny battery, on the contrary. This brought market for power bank. After nearly 10-year development, the battery, management circuits, material and other parts have made great progress.
3 .Development and popularization period
Led by the Apple, Samsung, Nokia, Motorola, Sony Ericsson, Huawei, ZTE and other major manufacturers had rapidly developed. They launched many electronic products, such as mobile phones, tablets, cameras, MP4, etc. And the importance of power bank had increasingly been recognized by users. Especially after the increasingly diverse functions of digital products in 2012, power bank was popularized at a fantastic speed to become a very popular product. By 2019, it has become one of the indispensable digital accessories for users.
