In the following, we analyze the development status of portable power bank:

    1. Portable power bank manufacturers mixed

    This is in the market we can see the portable power bank has a variety of shapes and all kinds of manufacturers. Because portable power bank is in an emerging industry. There is no uniform industry standard, nor is there a fixed standard of judgment. So many manufacturers in order to reduce the price, can only rely on reducing the production cost of portable power bank to reduce the price, so the quality of portable power bank is uneven. There are many unqualified manufacturers mixed in the market.

    2. The market share of portable power bank is relatively scattered

    According to the Internet Consumer Research Center in 2020, the top 50 manufacturers in the entire portable power supply market have a very fragmented market share. It's perfect competition. People only look at the competitive market, not the market share of the unified collaboration. Therefore, the market share of the whole industry is low in the present convenient power bank market.

    It is not difficult to see that the portable power bank is still an emerging product for the current social development, so the research in many aspects is not thorough enough, and everyone's cognition of the market is not clear enough, so the portable power bank still needs innovation.
