SMART Keychain Stun Gun – Key Features: SMART delivers 24 million volts through contact electrodes, creating electrical current that disrupts neuromuscular control. High voltage overcomes clothing resistance more effectively than lower-voltage units. The electrical discharge causes involuntary muscle contractions, temporarily incapacitating the target and providing opportunity for escape or further action. Duration of effect depends on contact time and target physiology, but brief contact typically provides several seconds of disruption.
The integrated LED serves dual purposes: illumination for navigation and target identification. Rechargeable lithium battery eliminates battery logistics while providing reliable power across multiple discharge cycles. USB charging interface works with standard phone chargers and portable power banks. Keychain attachment ensures constant availability—the most effective defensive tool is the one actually accessible when needed. Safety switch prevents pocket activation during normal carry. The SMART Keychain Stun Gun is available in black and pink color options.

SMART Keychain Stun Gun – Frequently Asked Questions
What does 24,000,000 volts actually mean for stopping power?
Voltage ratings indicate electrical pressure but don’t tell the complete story. What matters for incapacitation is sufficient voltage to overcome resistance (clothing, skin) combined with adequate amperage to disrupt neuromuscular function. The 24M volt rating ensures voltage is not the limiting factor. Current flow (measured in milliamps) creates the incapacitation effect. This unit provides both sufficient voltage and current for reliable neuromuscular disruption.
How long should I maintain contact for effective incapacitation?
Contact duration correlates with effect intensity. Half-second contact causes pain and muscle contraction. One to two seconds creates dazed condition and muscle weakness. Three to five seconds produces disorientation and loss of balance. Longer contact increases recovery time. Under stress, maintain contact until threat is neutralized—don’t release prematurely due to concern about over-application.
Will this work through heavy clothing like winter coats?
High voltage overcomes clothing resistance more effectively than lower-voltage units. The 24M volt output penetrates most clothing barriers including heavy winter garments. Direct skin contact produces maximum effect but isn’t required for incapacitation. Thick leather or multiple fabric layers may reduce effectiveness—target exposed areas when possible.
