The Pow Glove, or Power Glove, is the second item you have in your inventory upon starting.
You can use the Pow Glove to pick up Workbenches and other table like objects to move them. When picked up, the placeable item will be automatically equipped. At this point the player can unequip the item to place it safely back into the inventory. To pick up another placeable item, the Pow Glove will have to be re-equipped.
