As shown in the image below, when a USB is connected, the 5K is designed to receive power directly from the USB, not the battery. Out of the 5V 500mA provided by a typical PC USB port, 200mA is used for battery charging, while the remaining 300mA is used for the 5 K's operation.
This design is crucial in maximizing the battery's lifespan. If the system continues using battery power while charging, the lifespan will significantly shorten.
The built-in battery is not used when using the 5K as a USB DAC, and the entire system operates solely on USB power.
Even without the battery, the system operates well when connected to USB power.
Once charging is complete, the internal charging circuit cuts the current to the battery, and the battery enters a state of free discharge with all connections cut off.
Battery lifespan and device stability are not affected even if the 5K is always connected to a charger or PC USB port.
