A portable mixer and method include providing a support frame having wheels and an opposite handle, an outer drum having a rotational drive mounted on the support frame, a rotatable drum, and a removable mixing container held inside the rotatable drum. A pivot arm handle extends at least one meter from the outer drum center of gravity. At least two spaced apart top handles on the removable mixing container are positioned axially spaced apart from at least two spaced apart bottom grippers. A handle extends from the support frame a distance at least one meter from the wheels. A mixer blade promotes thorough mixing. A keyway groove secures the removable mixing container within the rotatable drum. The keyway groove also serves as the mixer blade. A sidewall key on the rotatable drum expands into and holds the removable mixing container. A lock-in insert on the rotatable drum expands into and holds the removable mixing container.
