About this item ALL-IN-ONE DESIGN: HOTO cordless screwdriver set contains 12 2-IN S2 steel long bits with hardness up to 60HRC, which are resilient, and durable. The screwdriver and 12 bits are stored in the frosted Al alloy storage box that has soft rubber top handle, creating comfortability and portability for users. MANEUVERABILITY: The screwdriver is maneuverable by screw-unscrew buttons and the circular LED shadowless lamp, which will be turned off automatically 10s after releasing the button. The lightweight of the screwdriver is 0.55lb and a double-layered soft grip made of high-strength plastic and TPE rubber enables users to operate the screwdriver using one hand. With a four-staged rotary knob and built-in intelligent chip, people can adjust the torque precisely to meet various needs. MINIMALIST BUT HIGHLY FUNCTIONAL: The 1500mAH large capacity battery, which is experienced 37 battery-related tests, provides ultra-long endurance that the screwdriver can run more than 1000 screws when it is fully charged. The high-speed magnetic motor and metallic gearbox provide strong and stable power output to the cordless screwdriver. And the universal Type-C charging interface makes the charging of the screwdriver convenient. HIGHLY RESPONSIVE: The built-in circuit board of the electric screwdriver can sense and stop the rotation as soon as the button is released, leaving no scratch or dent on the screws. And it is helpful to avoid injuring users' fingers due to over-rotation.
