auertech portable washing machine is vibrating like crazy during spin cycle, how do i fix this?

Let's get that stabilized. First, make sure the unit is on a level, solid surface and adjust the feet if it rocks. Second, for the spin basket, you must wring out excess water from the clothes first and then distribute them evenly inside. Don't exceed 4.4 pounds in the spin basket. An unbalanced load is the most common cause of shaking.
