My Buying Guides on Best Personal Alarm Keychain 2020
When I set out to find the best personal alarm keychain in 2020, I quickly realized there are several important factors to consider. A personal alarm is a compact, easy-to-carry device that can provide an extra layer of security by emitting a loud noise to deter attackers or attract help. Here’s what I learned and what helped me choose the perfect one for my needs.
1. Loudness and Volume
One of the first things I checked was the decibel level of the alarm. Ideally, a good personal alarm keychain should produce at least 120 decibels. This level is loud enough to startle an attacker and alert people nearby. I found that some models advertise their decibel range clearly, so I made sure to pick one that was tested for loudness.
2. Size and Portability
Since I wanted to carry the alarm every day, size and weight mattered a lot. A keychain alarm should be lightweight and compact so it can easily attach to my keys or bag without being bulky. I preferred a sleek design that didn’t add extra weight or take up much space.
3. Activation Mechanism
The ease of activating the alarm is crucial in an emergency. Most personal alarms work by pulling a pin or pressing a button. I personally opted for an alarm with a quick-pull pin that was easy to use under stress but secure enough to avoid accidental activation. Some even have a button press combined with a twist for extra security.
4. Battery Life and Replaceability
I wanted a device with long-lasting battery life because there’s no point in having an alarm that fails when you need it most. Many alarms use standard batteries that can be replaced easily. I looked for models with clear instructions on how to change batteries and ones that included spare batteries or charging cables if rechargeable.
5. Additional Features
Some personal alarm keychains come with extra features like built-in flashlights, LED indicators, or even GPS tracking. While these were not my top priorities, I found them useful in certain situations. A flashlight can help if you are walking alone at night, and GPS tracking can add another security layer when paired with a smartphone app.
6. Durability and Build Quality
Since the alarm is something I would carry daily, durability was a must. I chose models made from sturdy materials that could withstand drops and rough handling. Water resistance was also a plus because I didn’t want my alarm to fail if caught in the rain.
7. Price and Warranty
Finally, I compared prices to find the best value for my budget. Personal alarm keychains come in a range of prices, but I found that mid-range options often offered the best combination of features and reliability. I also checked if the product came with a warranty or satisfaction guarantee, which gave me extra confidence in my purchase.
My Final Thoughts
Choosing the best personal alarm keychain in 2020 required balancing loudness, portability, ease of use, and durability. By focusing on these factors and reading reviews from other users, I found a device that made me feel safer without sacrificing convenience. If you’re considering one for yourself, I recommend prioritizing what matters most to your lifestyle and testing the alarm’s loudness before making a decision. Stay safe!
