Output Current: USB double adapters come in various configurations, offering different levels of output current for each USB port.The output current is measured in amps (A) and determines how quickly a device can be charged. Higher output currents (e.g., 2.4A or 3.0A) are capable of charging devices faster.
USB Standards: USB double adapters typically support standard USB-A ports, but some newer models may also include USB-C ports, which are becoming increasingly common for charging modern devices.
