The power bank appeared in 2001, but it was called \"mobile power\" at that time.

The world's first power bank

At CES 2001, in a similar booth in the CES Sand Stall Pavilion, an international student demonstrated the first concept of \"mobile power\" products, he pieced together several AA batteries through a control circuit, used to power other digital devices. At that time, this humble thing attracted the attention of many exhibitors because it could charge digital products anywhere.

Third, the development of charging treasure
< br >
The first stage: the embryonic stage from 2001 to 2003
< br >
As mentioned above, the charging treasure appeared in 2001, but because the cycle life of the battery at that time was not enough, the battery size was large, the technology of the manufacturing process of the battery was not mature, and the smart phone market had not yet started, the charging treasure had no real market demand, and more was just a new concept speculation.

The second stage: growth period from 2004 to 2006
< br >
In view of the wide use of mobile power and the prospect of the future market, many large domestic manufacturers began to enter the industry.

At this time, the mobile power supply has the basic prototype: the management circuit, the chip, the battery cell is basically perfect, and the basic framework of a mobile power supply is formed. The market is also starting to pick up, but there is still no scale at home.

The third stage: development period from 2007 to 2010

The real popularity of the charging treasure is also the \"credit\" of the iPhone, when the non-removable battery of the iPhone 4 prevailed, most mobile phone manufacturers have followed the trend. In addition, Apple has made the iPhone thinner and thinner, but more and more features, resulting in the phone battery life can not keep up. This has brought opportunities to the charging treasure, and the market demand has begun to be active.
