The Charger is a 2014 Water Warriors blaster that holds 725mL of water. It takes its styling cues from the Drench 'n Blast, and looks very similar to it, unless it is the pump. It has 2 selectable nozzles mounted on a nozzle selector, a rather rare sight when it comes to water blasters; as nozzle selectors usually have 3 or more settings. Although the body looks similar to that of a Drench 'n Blast, the pump looks very similar to that of the 2 Steady Streams. It is classified as an air blaster. It has a special mechanism, the first seen in such water blasters, but the trigger mechanism had been used on Max-D blasters. After the initial filling and pressurization, one has a full secondary chamber, with the space behind it open to the atmosphere via a passageway in the valve's o-ring assembly. Pulling the trigger not only opens the nozzle, but also changes the 3-way valve configuration, linking the rear of the piston and the air pressure from the first reservoir together. The patents for the mechanism, patents US20130193161 and US20130192576, give examples of having 50 psi pneumatic pressure behind the piston, causing a force to act on it. The 2 heads of the piston are not the same size, which allows the magnification of force by reducing the area the force acts upon. By manipulating the piston head cross section ratio, one could have the smaller head exerting, say, 90 psi of pressure on the water in the secondary chamber. Since this is higher than within the reservoir, the check valve connecting the two stays closed. After the piston moves forward and forces the water through the nozzle, the entire system will be equalized. The air behind the piston is the same pressure as the water at the front of the secondary chamber, so the piston no longer moves. At this point, the system behaves like a normal air pressure blaster, with water exiting the reservoir through a check valve and going out the nozzle. If one releases the trigger before the system is completely depressurized, two things happen. First, the 3-way valve returns to its starting position, emptying out the air behind the piston. Second, water from the reservoir (having nothing opposing it in the secondary chamber) once again fills the secondary chamber until the piston is at maximum displacement.
