Best Personal Alarms

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 devices 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 and battery capacity 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 alarms available, 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 personal alarms have the loudest volume, longest battery life, and most painful sounds. We have our preferences, but these are all the best on the market.

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, or purse strap, with your hand grasping it. Just pull to sound the alarm. When met with unexpected danger, 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
  • 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 it waterproof. Watch out for fakes with this one, as there are some copycats that are real junk.

Vigilant PPS8

This Vigilant safety device uses AAA batteries instead of the watch batteries that are used in typical personal alarms. The result is a little more bulky device with a lot longer alarm runtime and one of the loudest personal alarms on the market. 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 activation, which we prefer, but it also has a button-press activation.

Vigilant PPS8 Personal Alarm
  • Best Battery Life
  • Loud (130 DB)
  • Good Customer Support
  • Large Size
  • Poor Build Quality

Vigilant PPS23

The Vigilant PPS23 uses standard watch batteries to maintain a small but easy to grasp size. This is more of a classic design, with upgraded and modern technology.

One of the worst complaints we saw with this personal alarm was that 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 good build quality!

Vigilant PPS23 Personal Alarm
  • U.S. Based Company
  • Designed in the United States
  • Easy Battery Replacement
  • Loud (130 DB)
  • Sensitive Button
  • Not Purse or Pocket Safe

The push button design will be preferred by some, especially since it’s a more traditional style that someone older may be more comfortable with. But, this makes accidentally setting it off more likely 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 that we found in an otherwise well designed and classic personal alarm.

Peroom Personal Alarm

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

This personal security alarm is very loud and will definitely draw attention.

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 alarms, but they are louder and have comparable construction quality.

Peroom Personal 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 2018.

Feedback is always appreciated!
