Prime Day deals on travel-ready carbon monoxide detectors

In an ideal world, travel should be fun, safe and hassle-free — but we know that’s not always the case. Flight delays, bad weather and overbooked hotels can always put a damper on a vacation, and it’s best to be prepared for the worst so you can mitigate any potential travel snafus.

One gadget — which is cheap and compact enough to easily travel with, but often overlooked — is a portable carbon monoxide detector. Having one can help ensure that your accommodations are safe and habitable.

For some, that might sound extreme, but in recent years, there have been a number of incidents at hotels and other accommodations in popular vacation destinations related to carbon monoxide poisoning — including one last year at a luxury Hyatt resort in Mexico that resulted in two fatalities. To us, that is reason enough to pack one of these handy, compact devices in your suitcase.

Carbon monoxide is nearly impossible to detect without assistance from a detector. At home, we sleep safely, knowing carbon monoxide detectors are working in the background to keep us safe. In some destinations abroad, hotels are not required to install carbon monoxide detectors in rooms, so it’s a good idea to have your own — just in case.

According to the U.S. Centers for Disease Control and Prevention, “Carbon monoxide (CO) is an odorless, colorless gas” that can kill and is produced by furnaces, gas ranges, grills, stoves, fireplaces, lanterns and engines. It affects people of all ages, but certain groups — including infants, elderly people, those with breathing problems and those with heart disease — are more at risk of getting sick.

Be sure to keep an eye out for the symptoms of carbon monoxide poisoning, especially if you (or someone in your party) is especially tired, drunk or intoxicated — this is when people are most vulnerable to carbon monoxide poisoning, since they will likely be unaware of the symptoms they’re experiencing. The CDC says the most common symptoms of carbon monoxide poisoning include:

• Headache
• Dizziness
• Weakness
• Upset stomach
• Vomiting
• Chest pain
• Confusion

Andrea Rotondo, travel expert and TPG’s director of content operations, explained why she brings a carbon monoxide detector when she travels:

Not all destinations have the same robust building codes or safety measures that we enjoy here in the U.S. I try to be hyperaware of my surroundings and potential safety issues. When I heard about several tragedies involving carbon monoxide deaths in hotels and vacation rentals in the Caribbean and Mexico, I knew I needed my own plan to keep my family safe. Now, on every trip, I carry a lightweight, portable carbon monoxide detector. It’s small enough that there’s always room for it in my carry-on, so there’s no reason not to bring it along for peace of mind.

With all of that in mind, you can feel comfortable and safe on your next trip by ordering one of the best carbon monoxide detectors.

It can easily sit on any tabletop at a hotel or Airbnb and has thousands of five-star reviews on Amazon. If the device detects carbon monoxide, an 85-decibel alarm will sound, and a red LED indicator will light up, providing both audible and visual cues that something isn’t right.

“It’s super lightweight,” said Nick Ewen, TPG’s director of content. “Since the batteries can be popped out and put back in, there’s no need to worry about it going off in a suitcase if the test button is accidentally pushed.”
