It is not possible to have no chip in the power bank. The chip in the charging treasure is the core component of the charging treasure, which is responsible for controlling and adjusting the power output, power detection, protection circuit and other functions of the charging treasure. If there is no chip in the charging bank, the charging bank will not work properly, and it will not be able to charge and manage the battery. Therefore, there must be a chip in the charging bank to work properly.
In addition, the chip quality in the charging bank will also affect the performance and service life of the charging bank. If the chip quality is poor, it may lead to unstable output of the charging treasure, inaccurate power detection, protection circuit failure and other problems, thus affecting the use of the charging treasure. Therefore, when buying a charging bank, we should choose a brand and model with a good chip to ensure the performance and service life of the charging bank.
The charging bank is not possible without a chip, because the battery cell is full to 4.2V, and the charging voltage must reach 5V
