The Best Keychain Gadgets & Accessories In 2021

1. Tile Pro High Performance Keychain Tracker

Are you always losing your keys, phone, or anything else? Find your stuff faster with the Tile Pro High Performance Keychain Tracker.

There are several ways you can take advantage of a Tile Pro and the Tile App:

If you keep a Tile Pro on your keychain, you can use your phone to find your keys or you can use your keys to find your phone – just try not to lose both at once!

Buy on Amazon

2. elago Keyring Headphone Splitter

If you want to watch videos with a friend in public on an electronic device, you’ll need the elago Keyring Headphone Splitter.

Unlike some headphone splitters, this one distributes the sound to both sides of both headphones rather than just one ear of each.

The clever impact-resistant key shape makes it super convenient to take with you everywhere. It’s perfect for traveling – watch movies together on your next flight.

Note that if you have a newer phone or tablet, you may not have a headphone jack, so this won’t work for you unless you have an adapter.

3. RovyVon Aurora 1000 Lumen LED Flashlight

Sometimes your phone’s flashlight just won’t cut it, or you’ll need a flashlight in a situation you wouldn’t want to risk your phone in (like a downpour).

Make sure you always have a sturdy, water-resistant flashlight handy with the RovyVon Aurora 1000 Lumen LED Flashlight.

This flashlight will adjust to any need with its 7 brightness levels, all the way up to 1000 lumens, which can shine farther than the length of a football field.

Since the battery is both rechargeable and replaceable (with an additional battery, sold separately), this flashlight will always be ready when you need it.

4. Original Self Defense Keychain Security Alarm

Scare off would-be attackers with the Original Self Defense Keychain Security Alarm.

Activating the alarm is as simple as yanking it from the clip attaching it to your keychain.

The battery should last about a year, but it’s also replaceable, so this keychain security alarm won’t become useless when the battery dies.

This item is also perfect for seniors who live alone and are at risk of falls.

Buy on Amazon

5. BACtrack Keychain Breathalyzer

Picture this: You had a few beers while watching the game with your friends, and now it’s time to drive home. You don’t feel impaired, but you could still be driving over the legal limit.

Avoid getting a DUI by using the BACtrack Keychain Breathalyzer. Small enough to fit in your pocket or purse, now you can test your blood alcohol content anywhere.

It’s easy to use: Simply fold out the mouthpiece, turn it on, and blow. You’ll find out your BAC in seconds and know whether you can legally drive or if you need to find another way home.
