This electric wrench is powered by the car's 12-volt cigarette lighter, making it ideal for use on the road. It is designed specifically for motorists who want to handle wheel changes independently and effortlessly in all conditions. The nut driver is equipped with a powerful motor that delivers up to 271 Nm of torque, making it easy to unscrew even the tightest bolts. This is especially useful in emergency situations when you need to quickly change a wheel on the road. For ease of use, the tool has a built-in LED indicator that illuminates the working area, making it easier to work in the dark. The kit includes two different sized impact heads (11/16 inch and 3/4 inch) that fit most standard wheel bolts.
