How to Do They WorK? 

Using a portable breath alcohol tester is simple. A user, using his mouth, just blows into the nozzle of the tester and the instrument instantly displays the BAC (Blood Alcohol Concentration) up to 3 or 4 digits. The rule of thumb is to wait for at least 10 minutes from the moment you’ve consumed alcohol in order for the device to produce reliable results.

You should wait 15 to 20 seconds immediately after obtaining one reading before doing the next test. These values can vary from product to product so make sure that you check the instruction manual before you use the breathalyzer unit.

Governments have passed strict laws to punish people caught driving on the roads in a drunken condition. Though the minimum acceptable BAC could differ from state to state or country to country, the most practiced norm is a BAC reading of 0.08. Any value higher is considered illegal for driving a vehicle.

Features and Qualities to Look For

All portable breath alcohol testers featured in this list are pocket-sized; some are even keychain models. To ensure safety and reliable results, look for units that have been approved by the FDA. Specs make a big difference. For starters, the number of digits (2, 3, or 4 digits) shown in the digital display does matter. The more digits the unit can display, the more precise the reading.

On a Budget

If you have the budget, it’s recommended that you pick the ones that use Fuel Cell Technology on account of its capability to maintain accuracy over a long period of time, not to mention that it requires less calibration than semiconductor sensors.

The Size of an iPhone

Most are the same size as an iPhone and can easily fit into a palm. They run on replaceable batteries, which come in the pack. The mouthpieces through which one blows have to be kept from any dust or other infections, and each instrument is supplied with a few spare ones so that one need not re-use the same mouthpiece with more than one person.

Featured below are the Best Portable Breath Alcohol Testers currently available in the market. It is for you to go through the reviews and choose the one that suits your needs.

Best Portable Breath Alcohol Testers for 2017

What’s to like about BACtrack S80

A big majority of buyers agreed on a consensus as to the BACtrack S80’s high-accuracy. It’s pretty consistent too. Use it repeatedly and you’re going to get the same results. Its wide array of features really work hand in hand to bring us a breathalyzer that is as accurate as it is reliable.

Moreover, the BACtrack S80 is quick and easy to use. Its compact build and sleek design make it easy to carry around with you in your pocket, which is a big deal considering you’ll want to have it with you when you go out for a drink.

What’s not to like

Final Word

With its nice combination of accuracy, reliability, and efficiency, BACtrack S80 sets the gold standard for breathalyzers. This is pretty well received on the market, averaging an impressive 4.2 out of 5 in terms of customer reviews (80% of reviews gave it at least 4 out of 5).

2. BACtrack Keychain Breathalyzer

BACtrack Keychain Best Portable Alcohol Tester

Click here for current price and more details

Weighing just under an ounce, BreathKey Keychain is the smallest and lightest breath alcohol tester in the world. Even for its small size, this breathalyzer is accurate and performs on a high level, in large part due to its fuel sensor technology. As the name implies, this tester is so small you can use it as a keychain, making it the most portable breathalyzer ever released.

Also deserving mention is the product’s nifty feedback feature, which produces a beep and an error message instructing the user to either “blow hard” or “blow long” if the user didn’t blow on the nozzle the right way.

  • Smallest and lightest breath alcohol tester in the world (weighs less than an ounce)
  • Fuel Cell Sensor Technology (same technology used by police officers)
  • FDA-certified
  • Engineered and built in the US
  • Support and calibration services have a one-day turn around
What’s to like about the BreathKey Keychain

The best thing buyers loved about the BreathKey Keychain is its size and lightweight construction (one customer confirmed that it’s small and portable enough to be stored in a “pocket protector”). Its performance is as equally impressive, with a big majority of buyers complimenting the little device for its exceptional accuracy, with one saying that it reads out in “thousands of a percent.” Impressive indeed!

What’s not to like

As accurate as the product is in terms of results, it does leave a lot of room for human error. The feedback feature compensates for this so it’s really no biggie, but it can be a little annoying at first. Also, you have to wait at least 30 seconds to do the next test, which can be time-consuming if you’re using the device on multiple users at one time.

Final Word

If you’re looking for a breathalyzer you can easily fit inside your pocket (or use as a keychain for that matter), you can’t go wrong with the BreathKey Keychain. It’s not perfect, but it does have a reliable feedback feature to make up for it. It’s pretty well-received too, with 65% of customers giving it a rating of 4 and above out of five.

3. BACtrack S35 Portable BAC Tester

BACtrack S35 Best Portable Alcohol Tester

For everything it does, the S35 is very much affordable. The extra mouthpieces are a welcome bonus as well.

What’s not to like

The S35 received some poor reviews stating that the product didn’t give accurate readings (one didn’t provide a reading above .02). The fact that these accounts run contrary to most of the reviews suggests that these customers might have received defective units. It’s a good thing that the manufacturer offers a one-year warranty, not to mention that they’re great reputation for providing excellent customer service.

Final Word

While prone to damage if not handled carefully, the S35 is for all intents and purposes an excellent product. If you’re on a tight budget, this one can serve you well. It’s received well, with 52% of customer reivews giving it a rating of at least 4 out of 5.

The unit can also be relied upon to provide results almost every single time.

Use this 10 minutes after drinking even just 2 pints of beer and you’re certain to get results. Lastly, it’s just the right size: a little smaller than an iPhone, which makes it more than convenient enough to put inside one’s pocket.

What’s not to like

The disposable mouthpiece sticks out like a sore thumb from the unit, which makes the product a little unwieldy to handle.
