Debunking the Voltage Myth: Understanding Stun Guns and Electric Current

Stun guns have become a popular self-defense tool, but there’s a lot of misinformation surrounding their functionality. One of the most common misconceptions is the emphasis on voltage. This article aims to debunk the voltage myth and shed light on the true factors that determine a stun gun’s effectiveness.

Understanding Stun Guns

Stun guns are devices designed to incapacitate a potential threat without causing long-term harm. They work by delivering an electric shock that disrupts the target’s muscle function. However, it’s not just about the voltage. The real effectiveness of a stun gun lies in its electric current, specifically, the amperage.

The Voltage Myth

Many believe that a higher voltage means a more potent stun gun. This misconception might stem from the dramatic sparks some high-voltage stun guns produce. However, voltage alone doesn’t determine the impact. It’s merely the force pushing the electric current. Think of it as water pressure in a hose; it dictates how fast the water travels but not the volume of water.

The Role of Amperage

Amperage, or current, is the real game-changer. It determines the intensity of the shock. A stun gun might have high voltage to ensure the current passes through clothing, but it’s the amperage that incapacitates the target. For instance, a lightning bolt has millions of volts, but the amperage is what makes it deadly.

Factors to Consider

Apart from voltage and amperage, other factors play a role in a stun gun’s effectiveness. The spark gap, waveform, and duration of the shock can all influence the outcome. For those considering purchasing the best stun gun in 2023, it’s essential to look beyond just the voltage.

Safety Considerations

While stun guns are a non-lethal self-defense tool, they should be used responsibly. Misuse can lead to unintended injuries. It’s crucial to understand the device’s capabilities and limitations and always adhere to local laws and regulations.


Are stun guns with higher voltage more effective?

Not necessarily. While voltage can help the current penetrate clothing, it’s the amperage that determines the effectiveness.

Is stun gun voltage the main factor in incapacitating an attacker?

No, amperage plays a more significant role in incapacitating a target.

Can stun guns cause permanent damage due to their voltage?

Typically, stun guns are designed to incapacitate without causing long-term harm. However, misuse can lead to injuries.

Are stun guns dangerous for the user?

When used correctly, stun guns are safe for the user. However, it’s essential to understand the device and use it responsibly.


The world of stun guns is more complex than just high voltage numbers. By understanding the role of amperage and other factors, one can make informed decisions and debunk common myths. Let’s spread awareness and ensure that misconceptions about stun gun voltage and amperage become a thing of the past.
