ZAP Double Trouble by PS Products is another light weight (6.9 oz), concealable, yet extremely effective single-handed drive stun device capable of delivering 1.2 million volts from two sets of electrodes. This device delivers stun power better than most traditional stun guns due to it’s space between the points of contact. The robust plastic composite material is also strong enough to take a beating and be used for striking if needed. The Double Trouble device works off of two CR123A lithium batteries and has a soft rubber contour grip. The size is what makes this tool a great take-along self-defense device, easily hidden in a jacket, shorts, purse, etc.
