The Developments of Power Bank

If someone asks you, when is the most anxious time during your whole day? When getting up in the morning? When you need to communicate with colleagues at work? Or when your digital devices, such as smartphones, earphones, or laptops, run out of battery? And I believe that most of us are anxious about the third one. Fortunately, the power bank is emerged. However, do you know who invented the first power bank in the world? What does it look like?

First Generation: 2001-2006

The world's first power bank first appeared in the CES exhibition in 2001. An international student showed the earliest product with "mobile power" concept. He put several AA batteries together with a control circuit to power other digital devices. At the time, this small thing attracted the attention of many exhibitors because it could charge digital products anywhere. After continuous optimization and upgrading, the preliminary power bank product was formed.

At this stage, the function was initially improved, and the product has officially entered the life of consumers. And the product at this stage mainly used lead-acid batteries, with small capacity and small output power, and there was almost no safety protection. At this stage, the technology was always applied in walkman, repeater, recorder, MP3, etc.

Second Generation: 2007-2010

The industry chains of power bank product were formed, and the polymer battery technology made breakthroughs, which started to be applied to power bank. Besides, the capacity began to increase.

So the features of the product at this stage were large and bulky, which were not convenient for carrying out. At the same time, the technology was always applied in mobile phone, camera, DV and so on.

Third Generation: 2011-2013

When iPhone 4 became popular, the smartphone market began to explode. However, iPhone was going to be thinner and thinner. And with more and more functions, which results in a decline in battery life of smartphones. Besides, the battery cannot be removed from the phones. However, this change drove the rapid development of power bank. Mainly with 18650 batteries, large-capacity power bank become popular.

At this stage, the products were characterized by large capacity and output power, and they began to pay attention to product safety protection.

So, the products that were typically applied to this technology were smartphones.

Fourth Generation: 2014-2018

The market competition was fierce, the industry was more mature, and the safety of polymer batteries was improved, so the power bank had begun to be widely popularized; The industry-leading battery manufacturers had begun to intervene in the production of power bank batteries; Meanwhile, the fast charging technology has begun to appear and be fully popularized to the public, and the charging speed has been greatly improved; The new national standards for power bank had been implemented, and there were clear specifications and requirements of the power bank from the national level.

At this stage, the features of the power bank on market were fast charging power bank, personalized power bank, ultra-thin power bank (Xiaomi ATL polymer power bank was released in November 2014; the first QC2.0 certified power bank was released in March 2015). And the technology was always used for smartphone, tablet, etc.

Fifth Generation: 2019-Now

By 2019, the power bank has become an indispensable digital accessory for consumers. In addition, the development of new energy vehicles has led to continuous breakthroughs in battery cell technology. The energy density of the battery cell is continuously improved, the size is smaller, and the power bank is safer. At the same time, fast charging technology is mature, fast charging protocols are more abundant, compatibility is better, and security is also enhanced.

For power banks, the products at this stage are more refined and compact, the texture is comprehensively improved, the charging speed is faster, the experience is better, and it is safer and more reliable.

So the power bank is always applied for smartphone, tablet, laptop, etc.

Today, power bank is a necessary accessory for most people, some accessory manufacturers that focus on quality, brand building, and R&D innovation have in-depth insights into the needs of consumers, and have launched feature-rich power bank series.

UGREEN, the manufacturer of electronic accessories and consumer technology products. To solve the security point that most people worry about, UGREEN has designed a new series of power bank with the first-class level chip, which are going to be launched. Are you curious about it?
