Personal Safety Alarms

Personal alarms have always seemed like a great idea that just didn’t quite work as good as expected. They were never loud enough to be painful, and most would not even get the attention of people a few hundred feet away before it was far too late to matter. In a parking lot with other noises around you, all the alarm did was make you feel better by clutching your electronic safety blanket while you were an easy target.

But that was in the past. Electronics have improved incredibly over the last 10 years, and there are some real contenders in the personal alarm market now. We are going to shortlist the top 4 that we would give to our grandmothers. We were going to list the top 5 personal alarm options available anywhere, but we are way too picky at The High Tech Society and could not find a 5th one that was worthy of our list.

These keychain alarms have the loudest volume, longest life, and most painful sounds. We have our preferences, but these are all the best to use in an emergency.

BASU eAlarm+

The BASU eAlarm+ (aka: Robocopp) came on the scene in 2016 and made a huge splash with its innovative design. This personal alarm is designed like a hand grenade. Keep it on your keychain, belt loop, bag, or purse strap, with your hand grasping it. Just pull the key ring to sound the alarm. When met with unexpected danger or a sudden attack, the natural human reaction is to jump. The brilliance of this design is that it exploits that to sound the alarm so that you do not have to think about turning it on or fumble for a switch.

BASU eAlarm 130db Alarms
  • Great Design
  • Easy to Trigger
  • Loud (120 to 130 DB)
  • Waterproof Alarm
  • TSA Approved
  • Fits Anywhere
  • The battery cannot be changed
  • Beware of fakes with this


Battery life is about 5 years, so not being able to change it is not a huge problem when you consider that is the compromise for having a waterproof alarm. Watch out for fakes with this one, as some copycats are real junk.

Vigilant Security Alarm

This 130db personal alarm uses AAA’s instead of the watch batteries that are used in typical a personal alarm. The result is a little more bulky device with a lot longer alarm runtime and a keychain with an alarm which is one of the loudest ever tested. The batteries are also easily replaceable.

With the extra power, it can also run a small integrated LED flashlight, which is nice for those dark key-fumbling moments when you are trying to hurry to get out of a lonely parking lot.

Like the Robocopp above, it has a ripcord style alarm, which we prefer in an emergency, but it also has a button-press activation.

Vigilant 130db Personal Alarm with Backup Whistle
  • Best Battery Life
  • Loud (130db)
  • Good Customer Support
  • Large Case Size
  • Poor Build Quality

Vigilant 130db Alarm

The alarm uses standard watch batteries to keep it small but easy to grasp on your keychain. This is more of a time tested classic design, with upgraded and modern technology.

One of the worst complaints we saw with this personal alarm was where someone dropped it in a puddle in a parking lot and it went off and wouldn’t stop. They tried everything to stop it, including submerging it in water for 10 minutes, stomping on it, and even running it over with their car 8 times! Their complaint was that they couldn’t make it stop or break it!

It is not sold as waterproof, but that’s pretty well built for an emergency situation!

Vigilant 130db Personal Alarm Keychain
  • U.S. Based Company
  • Designed in the United States
  • Easy Battery Replacement
  • Loud (130 DB)
  • Sensitive Alarm Button
  • Not Purse or Pocket Safe

The push button design will be preferred by some, especially since it’s a more traditional alarm that someone older may be more comfortable with. But, this means that the keychain safety alarm can be activated too easily as the button is easy to depress, so if you have it in your purse or pocket you could easily set it off accidentally. This was the biggest negative found in an otherwise well made and classic personal alarm.

Peroom Personal Alarm

The Peroom Personal Alarm is by far the loudest, lowest priced, and best-rated self-defense alarm available. It has some of the classic design of the Vigilant models while keeping the pull-pin method of activating the alarm. Because it uses a clip and lanyard cord, it can be easier to activate the personal alarm in an attack or emergency.

This personal security alarm is very loud and will definitely draw attention when you need help.

We are VERY critical of low priced things made in China and expected to breeze passed this. Instead, we found ourselves wondering why a 3-pack of these costs less than the Vigilant personal alarm above, but they are louder and have comparable construction quality.

Peroom 140db Emergency Personal Panic Alarm
  • Loudest (140 DB)
  • Price
  • No Push-Buton Activation

In the end, this is the personal alarm that we would give to someone we cared about. It comes in a 3-pack and has a pull-pin activation, so carrying 2 and activating both devices simultaneously is easy (put two straps on your wrist) and makes more noise than anything else on the market. Overall, this is the best personal alarm of 2019.

Feedback is always appreciated!
