A stun device is a non-lethal, pain compliance tool that can be used as an effective self-defense tool when it makes direct contact with an attacker. These devices work by creating electrical pulses that send the nerves cells that control the muscles into chaos, causing pain.
Stun devices are designed to be used as a deterrent against attack, to reduce the effects of a violent crime should an attack happen, or to temporarily immobilize an attacker enabling a victim to flee to safety.
There are many voltage claims on similar devices on the market today. However, to accurately measure the electrical current of a stun device, the current must be measured in amperes. Damsel in Defense stun devices measure at 18mA, allowing them to deliver electrical shock to an individual without classifying them in the range of potentially lethal devices.
