Dual USB charger

The dual-port USB charger has two charging ports that can charge two USB charging devices at the same time, making full use of the socket space.

Dual-port USB is developed with the increase of electronic portable devices in recent years and the birth of some devices with large charging current. Previous mobile phones, MP3 and other portable devices have smaller battery capacity and less demand for chargers. Generally, the charging current is within 0.5A. In recent years, smartphones and tablets have developed rapidly, and these devices have been increasingly equipped with larger capacity batteries due to their high power consumption, and are generally equipped with larger capacity batteries. In particular, the birth of the IPAD has raised the rated charging current to 2.1A, and conventional chargers have been unable to provide such a large charging current. This resulted in a number of chargers rated at more than 2.1A or even 3.1A. At the same time, in order to meet the charging requirements of more and more digital devices, the charger with larger rated current is usually set to two charging ports, which is convenient for charging the tablet and one other digital device at the same time.

Not only that, but now the mainstream charging treasure is basically set to two charging ports for the same reason. A large current port, a conventional current port.
