Looks Like a Pen. Works Like a Stun Gun.
The Stun Pen measures 6⅜” x ¾” — exactly the profile of a standard ballpoint pen. Made from aluminum alloy rather than plastic, it has the weight and feel of a quality writing instrument. Clip it to your shirt pocket, your jacket, or your notebook and it disappears into the background. That’s the practical value of a disguised stun gun: it’s accessible without being obvious.
At 40,000,000 volts and 2.5 milliamps, the Stun Pen delivers output consistent with full-size stun guns in a form factor that fits in a shirt pocket. The safety switch prevents accidental activation, and the LED battery indicator eliminates guesswork about charge status.
Who This Stun Pen Is For
Office workers, healthcare professionals, and anyone who works in environments where a conventional stun gun would draw unwanted attention. The pen profile means it sits naturally in a pocket or on a desk without raising questions. It’s also practical for commuters — subway riders, bus passengers, and anyone who moves through crowded spaces where drawing a visible defensive tool isn’t ideal.
The USB rechargeable battery makes it compatible with any standard charging setup you already have — laptop, wall adapter, car charger. No proprietary cables, no batteries to replace. The pocket clip keeps it in a consistent, reachable position so there’s no fumbling when you need it.
Is This the Right Choice for You?
Choose the Stun Pen if you want:
- A stun gun that doesn’t look like one — full concealment in a pen profile
- Pocket clip carry without a holster or dedicated pouch
- USB rechargeability with an LED indicator so you always know your charge status
Consider something else if you need:
- Higher milliamp output — larger stun guns deliver more current
- A built-in flashlight for low-light situations
- A wrist strap disable pin safety feature
How It Actually Works
The Stun Pen’s electrodes are positioned at the tip of the device. Activating the safety switch arms the unit; pressing the trigger delivers 40,000,000 volts through whatever makes contact with the electrodes. The aluminum alloy body conducts the discharge precisely — there’s no current transfer to your hand through the grip.
The rechargeable lithium battery powers the device directly via the included USB charging cable. The LED battery status indicator shows whether the device is charged, low, or needs immediate charging — removing the uncertainty that comes with devices that have no charge feedback. A full charge takes a few hours and maintains capacity for extended periods between uses.
The safety switch is a physical toggle that must be in the active position before the trigger functions. This prevents accidental discharge in a pocket or bag, which matters when the device is shaped like something you’d normally carry clipped to your clothes all day. The combination of safety switch and pocket clip makes for a carry setup that’s both secure and accessible.

Frequently Asked Questions
How do I know when the Stun Pen needs to be charged?
The LED battery status indicator on the device shows current charge level. When the indicator shows low charge, connect the included USB cable to any standard USB power source — laptop, wall adapter, or car charger. A full charge typically takes a couple of hours. Charging it after notable use or on a regular weekly schedule keeps it ready without relying on the indicator alone.
Is the safety switch reliable enough to carry in a pocket all day?
Yes. The physical safety switch must be manually toggled to the active position before the trigger can fire. In the safe position, pressing the trigger does nothing. This is the same mechanism used on full-size stun guns and is the standard approach to pocket-safe stun gun carry. Keep the switch in the safe position whenever the device is not in active use.
What’s the difference between volts and milliamps in a stun gun?
Voltage determines the stun gun’s ability to penetrate clothing and reach the body. Amperage (milliamps) determines the intensity of the muscle disruption effect. The Stun Pen’s 40,000,000 volts ensures good penetration through typical clothing layers. The 2.5 milliamp output delivers an effective defensive shock. Both figures matter — voltage without adequate amperage produces a less effective result.
Will the current transfer to my hand when I use it?
No. The electrical discharge travels between the electrodes at the tip of the device, not through the body of the unit. Holding the aluminum alloy handle while activating the stun pen does not transmit current to your hand. This is true of virtually all stun gun designs — the body is insulated from the discharge path.
