Features: DC 5V1A power supply, the input interface is a standard TYPE-C port, and it is also equipped with a USB to TYPE-C cable and a Ni-battery pack + two battery covers, which is very convenient to use. The built-in circuit has overcurrent protection for input current, short circuit protection for output, and overvoltage and reverse polarity protection for battery charging. This product uses a dedicated Ni-battery charging management IC design. When charging, when the Ni-battery voltage reaches 2.85V, it will automatically stop charging, which can effectively protect the controller and Ni-battery pack. It also has overvoltage protection, overcurrent protection, output short circuit protection, and reverse polarity protection. When charging, you can directly see the charging status of the battery pack on the controller from the light-emitting color of the two controller patterns on the front display panel, which is very intuitive. When the input power is sufficient 5V 1A, the maximum charging current for a single controller can reach 300 mA ~ 320mA. When two controllers are charging simultaneously, the maximum charging current can be guaranteed to be 250mA ~ 300mA. : Applicable models: For Battery capacity: 800mAh x2 Material: ABS Color: black Package contents: 1 x for Base 1 x Game Card Holder 1 x Headphone Holder 2 x Ni-battery pack 4 x Battery Cover 1 x USB to TYPE-C cable Only the above package content, other products are not included.
