Bullet car charging -- full of expectation

Car charging must conform to a principle. For the battery charging of small consumer electronic equipment, the USB port of bullet car charging is an economic and practical power supply. In order to fully comply with the USB 2.0 specification, the load connected to the USB port must be able to communicate with the host in two directions.

The load must also meet power management requirements, including low power consumption mode, and means for the host to determine when it needs to draw large current from the port. Although some compatible systems can adapt to most USB hosts, unexpected results sometimes appear. Only a good understanding of USB specification requirements and load expectations can achieve a good balance between specification compatibility and load complexity. So USB car charging, from interface conversion to voltage conversion, and current power requirements match the needs of electrical appliances Sometimes you will encounter that the USB you purchased can't charge your appliance, so there may be matching problems.
