FiiO CP13 Portable Stereo Cassette Player (Sky Blue)

The CP13's motor is powered by a high voltage 4.2V power supply, more than the 1.8V or 3V typically found in today's cassette players. This power supply works in tandem with a motor speed stabilization circuit, which increases the drag on the motor as necessary to ensure stable movement speeds - which mitigates unwanted pitch changes and also allows the CP13 to be able to handle more cassette tape types.

The CP13 features a carefully crafted dual-color all-aluminum chassis. The clearly visible "0" screws that act as a perfect complement to the square yet round design mean the CP13 is an example of beauty coexisting in harmony with ergonomics. The buttons of the CP13 undergo hard oxidation, making them more wear and corrosion- resistant. Behind the aluminum alloy volume knob is a large analog volume potentiometer, which compared to the fial potentiometers used in cassette players is not only more reliable and provides more stable sound, but also simply feels better when used.

The CP13 employs an 1800mAh lithium cobalt oxide battery, chosen for its ability to provide robust power for longer periods of time than ordinary batteries. In fact, the CP13's battery allows it to achieve 13 hours of battery life and 268 days of standby time.

The CP13 is powered by a lithium battery, which can be recharged through the USB Type-C port when connected to a 5V power adapter. And FIlO's vast experience in designing safe charging circuits with protection mechanisms ensures you can use the CP13 while charging worry-free.
