Built in lithium battery ???? The wireless controller contains 500 MAH lithium battery, which saves the trouble of installing battery, supports continuous operation for 5-6 hours, and a 2.65-foot charging cable is distributed in the package. ???? Double vibration feedback ???? The controller is equipped with a vibration motor, which brings you a variety of vibration experiences, such as head explosion, explosion and collision in the game, making you feel like you are on the battlefield, full of realism. ???? Support multiplayer games ???? The wireless handle can be used by 2-4 people at the same time.
