How Does Pass-Through Charging Work in External USB Batteries?
Pass-through charging allows an external USB battery to charge itself while simultaneously powering another device. This process involves several key components. The external USB battery contains a battery management system that controls the charging and discharging of power. When you connect the battery to a power source, it receives energy, which is stored in its internal battery.
Simultaneously, if you connect a device, such as a smartphone, to the battery’s output USB port, the battery management system directs power to both the internal battery and the connected device. The system prioritizes the device if it requires immediate power. Once the connected device is charged, the remaining energy continues to charge the external battery.
This method of charging is efficient. It ensures that your device remains powered without waiting for the battery to fully charge first. The logical flow includes connecting the battery to a power source, connecting the device to the battery, and allowing the battery management system to balance power distribution. In summary, pass-through charging enables external USB batteries to charge while providing power to other devices effectively and simultaneously.
