Personal Alarm Vs. Stun Gun – Which Provides the Best Protection

Large Call to Action Headline

You will have encountered stun guns if you have been searching for a non-lethal self-defense weapon.

Not to be confused with Tasers, which fire a projectile, stun guns are handheld devices that deliver an electric shock when held to an assailant's body.

Stun guns undoubtedly look impressive and will bring an attacker to their knees. But how practical are they in real-world situations, and how do they stack up against a personal alarm?

Deciding on which type of self-defense product will be best for you can be tricky. So, in this post, we compare the pros and cons of stun guns and personal alarms to help you make an informed decision.

Personal Alarm Pros and Cons

Personal alarms are inexpensive self-defense devices that emit a loud siren when activated. They can be purchased by anyone and carried anywhere.

The sound of a personal alarm will attract attention, which is what a criminal fears the most. An alarm could bring the police or help from bystanders, which could lead to an assailant's arrest.

Personal alarms are very loud. Consequently, they can cause discomfort and disorientation. However, a personal alarm will not injure anyone, which some see as a disadvantage of these devices. Still, many people don't want to fight with anyone physically; they would rather have a passive self-defense device like a personal alarm.

Here's a summary of the pros and cons of personal alarms:


  • Inexpensive
  • Effective
  • Reusable
  • Anyone can buy one
  • Permitted on airplanes
  • Permitted on college campuses
  • OK for children
  • Do not cause injury


  • Do not disable an attacker
  • Batteries need replacing
  • Could be grabbed by an assailant
  • Might be ineffective in a remote area

Example Personal Alarm

KOSIN Safe Sound Personal Alarm

KOSIN Safe Sound Personal Alarm

The KOSIN Safe Sound Personal Alarm is a straightforward device and an excellent example of this type of alarm. It has a 140dB alarm siren and keychain and is activated by pulling the pin from the body with a lanyard.

Stun Gun Pros and Cons

Stun guns deliver a powerful electric shock, causing intense pain and muscle spasms, disabling an attacker. The electric charge is delivered through metal probes, so you must get close to an attacker for these products to be effective. However, firing a stun gun into the air will cause sparks and loud noise, acting as a deterrent.


  • Excellent stopping power
  • Reusable
  • Works in all weather conditions
  • Can dissuade an attacker


  • Prohibited in some states
  • Prohibited in some locations
  • Prohibited in some countries
  • Need to get close to an attacker
  • Purchase Restrictions
  • Not suitable for children
  • Need recharging

Example Stun Gun

VIPERTEK VTS-989 Heavy Duty Stun Gun

VIPERTEK VTS-989 Heavy Duty Stun Gun

Our example stun gun is the VIPERTEK VTS-989 Heavy Duty Stun Gun. This rechargeable stun gun is compact, easy to carry, and incorporates a flashlight. When used against an attacker, the device causes extreme pain and temporary immobility.


A stun gun undoubtedly has excellent stopping power. However, you need to get up close to an assailant to use a stun gun to its full effect. Another significant drawback of stun guns is that they are prohibited in some states and locations.

It is also worth pointing out that stun guns cause extreme pain; you must be prepared for that if you use one. Plus, stun guns can be fatal if used on someone with a heart condition.

On the other hand, personal alarms won't bring an attacker to their knees. Still, the sound of an alarm siren is sufficient to deter most criminals. And anyone can use a personal alarm, even children. Furthermore, there are no restrictions on where you can carry a self-defense alarm.

So, personal alarms are your best bet if you want a self-defense device you take anywhere. Likewise, if you want to buy a personal protection product for a child or college student, an attack alarm would be best. But, if you are after stopping power, a stun gun wins hands down.
