A powered tile breaker has an adjustable frame and the frame is further comprised of a handlebar member, a foldable shaft, a base member, and wheels. The base member holds a chiseling assembly which comprises a main electric motor located inside a motor casing. The motor powers a chisel member. The chiseling assembly is angularly adjustable by way of an actuator member which consists in a secondary electric motor driving a piston. The piston has one end rotationally connected to the base member, and the actuator member is rotationally connected to a lever member which extends from the chiseling assembly and which connects at a pivot point.
