7. Siepem Personal Alarm Keychain High Decibel Self Defense

SIEPEM Personal Alarm KeychainCheck Latest Price on Amazon What we love about this product is its versatility. One thing about personal alarm key chain is that its principal use, the alarm, is not frequently used, which is a good thing because it means you are not facing a situation that calls for it, but we can certainly appreciate wanting a multi-purpose alarm that has more every day uses. This product offers exactly that. It can be plugged into your phone or laptop, and can be used as a speaker! Also, other than the alarm being 130 dB loud, the alarm is human voice calling for help, which cuts down the possibility of your alarm being mistaken as other loud sounds such as a car alarm. In addition, it has an LED flashlight and another light to complement the alarm. Pulling out the pin activates the alarm and red and blue lights blink alternatively, resembling a police car light. This device is rechargeable, with a USB port and a battery life indicator to make sure you have your alarm fully charged before going out with it. It is designed like an adorable ladybug and it looks great as a personal accessory on your bag or on your keys. It is also waterproof and high temperature resistant, two great features to make it usable in adverse conditions, say if you go hiking or trekking or on rainy days.

8. EPOSGEAR Metallic Mini Minder

EPOSGEAR Metallic Mini Minder Loud Personal Staff Panic Rape Attack Safety Security Alarm 140dbCheck Latest Price on Amazon This is a great choice of personal alarm if you are looking for a professional level quality. This product has been accredited by the UK Police, which proves its reliability. It has a metallic colored body and has a very loud alarm of 140 dB. Most alarm key chains are 130 dB loud (which is certainly loud enough) so the extra 10dB here is slightly overkill,  however for some this extra 10 dB might be the definition of "best personal alarm key chain " considering it has the highest output of any in our list.  For instance, those spending a lot of time in the outdoors would get a lot of value from that extended range. A pin attached to a cord is used to activate the alarm and a separate key ring is used to hang it from your bag strap or belt loop. This is an important feature because it helps to avoid accidental removal of the pin, which would cause a false alarm.


  • 140 dB alarm
  • Alarm cord and key ring are separate
  • Wrist strap
  • Accredited Product


  • Not as small as other alarms

What to keep in mind when buying a personal alarm key chain

Now that you know about the eight best personal alarm key chains in the market, we will give a quick overview of the things you may consider to buy one:


How active are you? Would you carry it cycling, jogging, and solo-adventures? If it is going to undergo rough movements, make sure the key ring is strong enough to not let the alarm fall.

Is the attachment ring separate from the activation pin

For some products, the key ring or the pin is same as the ring that the alarm is hung from your bag strap or your key and this might be a problem since it may cause the pin to be pulled out accidentally which will cause a false alarm.

Activation system

Is it a pin or a button? How easy do you want it to be to turn on and off the alarm?


In most cases, it is going to be a part of your accessories so make sure it goes well with your overall style. Do you want a standard design, a cute one for your children or one with a little more flare?


Some use AAA batteries, some use watch batteries and some are rechargeable using a USB cable.

Additional features

Some have flashlights and speakers that can be more practical for every day use.
