Đèn pin này hoạt động theo định luật cảm ứng điện từ Faraday. Khi cầm đèn pin và bóp, nam châm chạy xuyên qua cuộn dây, từ đầu này đến đầu kia và ngược lại. Khi nam châm di chuyển, số lượng đường sức của từ trường đi xuyên qua mặt cắt của cuộn dây thay đổi theo thời gian. Khi đó, dòng điện xuất hiện trong cuộn dây khép kín: Cơ năng chuyển thành điện năng. Cục pin sạc sẽ nạp điện từ cuộn dây để giúp đèn phát sáng. Đèn pin không dùng pin rất tiện lợi, có thể sử dụng bất cứ khi nào, ở đâu.
