“Cartool”is a wireless power tool brand founded by Charles LEI.
In November 2019, Charles LEI and his friends drove through the no-man's land in Lop Nur. One of the cars had a flat tire. The weather was cold and the plateau climate was cold. They took turns changing tires,everyone is exhausted. He realized how important it was to have a portable set of power tools outdoors.
The creative Charles immediately organized the R&D team for development,and after many researches and tests, the first cordless impact wrench was developed in 2021. It adopts a brushless motor and has a large torque of 700N.m, which can easily screw 50 sets of screws.
At the same time, Charles thought of his self-driving experience and found that in addition to changing tires outdoors, he also needs to pump air, wash the car, and vacuum, so that he can better maintain the car. As a result, a series of power tools such as Cordless Tire Inflator, Cordless Pressure Washer, and Cordless Vacuum Cleaner were developed.
