Top 15 Essential Safety Gadgets for Solo Hotel Travelers

As a rather clumsy youngster, my mother frequently advised me to remain vigilant about my surroundings. This cautionary advice transformed into something profound when she reiterated it just as I was about to study overseas in London during my second year of university. Indeed, London appeared to be a safe destination, yet it was significantly larger than the small island of Bermuda where I was raised.

Fast forward to the present, and I’ve been traveling alone for more than ten years; while I comprehend how exhilarating this can be, it also necessitates a degree of preparation to maximize these solo adventures. Fortunately, there are numerous travel safety gadgets you can pack to enhance your sense of security, particularly during solitary nights in a hotel: consider door stop alerts and portable carbon monoxide alarms that will provide reassurance. And, the majority of these are just a click away on Amazon.

Travel more safely and intelligently in 2025 by gathering these 15 top personal safety devices for hotel rooms, Airbnbs, and even your residence.

Sabre Wedge Door Stop Alarm 

I enjoy arriving at a new hotel: I envelop myself in the soft robe and settle in as I get accustomed to all the facilities. Yet, when it’s time to retire for the evening, I often feel a bit uneasy about knowingly being alone in an unfamiliar place. This door stop alarm alleviates my concerns about someone entering the room in the middle of the night, as the 120-decibel sound would halt anyone in their tracks (and wake me!); additionally, the grip prevents the door from swinging open farther. Its lightweight and compact structure facilitates easy packing in any carry-on or suitcase.

Sliding Door Security Bar

Since not every entrance operates on a hinge, this sliding door security bar is ideal for an atypical entryway. Its adjustable length also enables it to secure windows effectively, as noted by one Amazon reviewer who mentioned they used it for “a smaller sliding window, and [it] performs just as well.” That same reviewer utilized it under a doorknob to prevent anyone from accessing the handle from the outside. While the proportions of the bar might seem cumbersome to travel with, it can be disassembled to a compact length of 18 inches, making it fitting for most luggage.

RFID-blocking Sleeves

When I initially began my solo journeys, I recall my father gifting me a set of RFID-blocking sleeves for my passport and credit cards. I utilized the passport sleeve religiously; however, I reserved the credit card sleeves for situations where I felt it was necessary. Even though I hoarded the sleeves, the technology has become increasingly accessible: now multi-packs are available to ensure every card is protected. While you might not find them necessary during downtime in the hotel, I always feel more secure knowing my cards are safeguarded in these sleeves during check-in — particularly in lobbies filled with numerous individuals in close proximity to my belongings.

Apple AirTag 4-pack

While many travelers employ their AirTags to monitor their checked baggage during transit to their destination, AirTags are also incredibly useful at hotels. Allow me to clarify: I cherish arriving early at destinations, but the downside of this is that my room typically isn’t available. For this circumstance, I rely on an AirTag to feel at ease leaving my bags with the concierge while I venture out to savor some coffee and make the most of my initial hours in a new city. These trackers are sleek and lightweight, so there’s no excuse

not to carry one in your luggage constantly; moreover, if you find yourself buying an excessive amount of keepsakes during a journey and you must check your bag, you’re already furnished with a tracker.

Outlet Extender With USB and Surge Protection

After facing issues with broken devices following power interruptions caused by storms during my early solo traveling years, I consistently carry a surge protector, whether it’s an outlet extender or a converter. This specific extender features USB ports and surge protection to guarantee that I can safely charge my devices without the anxiety of damaging them in a new location. It’s compact and increases the usual single power outlet found next to a hotel bed, allowing you to keep your devices nearby while working or resting.

Amir Portable Safe Box

Here’s a bold assertion: I seldom utilize hotel safes. It’s less about distrust and more an idiosyncrasy — I prefer to keep my valuables within reach, allowing me to grab them quickly in case of an emergency. Hence, this portable safe box is ideal as it accommodates jewelry, cash, a passport, and a wallet inside, meaning I could swiftly take it with me if necessary. Although larger items, like laptops or cameras, won’t fit inside, this portable container is an excellent way to keep all your smaller valuables consolidated.

Carbon Monoxide Detector

This four-in-one detector not only senses carbon monoxide while traveling but also identifies other flammable and explosive gases, such as LPG (methane), propane, and natural gas. “The plug-and-play feature is incredibly handy, making it effortless to set up in any room or even bring along for RV trips,” mentioned one reviewer on Amazon. “The detector is responsive and dependable, assuring that any gas leaks are identified without delay. This extra layer of safety is priceless.”

Portable Door Lock

For under $10 (essentially, pass on your favorite coffee for one week and you have enough for it!), this portable door lock will provide you peace of mind when you lay down on the hotel mattress. Made from stainless steel, the lock is lightweight yet sturdy and straightforward to install. Simply insert the claw into the gap of the door and adjust the screws until it’s secure; then, tighten the butterfly screw, and rest assured knowing you have an additional layer of protection on your door. One Amazon reviewer remarked that they bought three for a vacation rental and ended up using all of them: “So easy to install and a great sense of security for a low price.”

Door Jammer

Occasionally, an additional lock just doesn’t suffice. If you wish to incorporate several layers of privacy into a hotel room, purchase this door jammer that fits most inward-opening doors. Its installation is uncomplicated and can endure significant force from inward pushing. One Amazon reviewer cherished it to the extent that they utilize it at home to secure their two French doors that lack a lock. “It genuinely becomes quite challenging to open the door when this is installed,” they stated.

Hidden Camera Detector

When you consider the number of individuals who have occupied the hotel room prior to your stay, it’s easy for your imagination to drift regarding the credibility of hidden camera horror tales — resulting in many opting to avoid the potential danger. This elegant multi-functional gadget is a valuable addition as it can identify concealed listening devices, pinhole cameras, wired and wireless hidden cameras, GPS monitors, and more within a range of 5 centimeters to 15 meters. Additionally, it features several detection modes, such as RF (radio frequency) detection, magnetic field detection, and infrared (IR) scanning. Its slim profile and rechargeable design alleviate the need to carry extra batteries when traveling.

Personal Safety Alarm

It’s wise to have a personal safety alarm close at hand, whether you’re returning from dinner in the dark or simply settling in for the night while stowing the device under your pillow. An alarm like the She’s Birdie device, which emits a loud noise when the pin is pulled, could dissuade an intruder. “The alarm’s LOUD siren is truly captivating. It releases a piercing sound that’s impossible to ignore, making it a formidable barrier against potential threats,” one user remarked. “Activating the alarm is simple, and the quality of construction feels solid and dependable.”

High Lumens Flashlight

A basic flashlight is arguably one of the most underrated travel safety tools. It can be beneficial if someone breaks in and you need to illuminate the area to show that someone is present in the room or facilitate your navigation during a power failure. It can also be useful if you need to evacuate during a fire drill or a real fire. This compact size delivers impressive performance: weighing under a pound and measuring around four inches, the beam can reach up to 500 feet.

Privacy Cover for Peep Hole

Although a simple tissue placed in the peephole of a hotel door can enhance security in a pinch for frequent travelers, a cover specifically created for privacy is beneficial to keep in your luggage. Just attach this over the interior door’s peephole and rest easy knowing that no one can utilize a device to look inside. The cover is durable and minimally visible, so housekeeping will likely not remove it.

Hanging Door Alarm

If you’re a heavy sleeper, you might want to invest in this hanging door alarm that will notify you if someone attempts to enter without your consent. Simply hang it on the inside door knob (or off a window lock if you’re more worried about that entrance), flip the switch, and be assured that the 120-decibel alarm will activate should anyone attempt to gain access.

Motion Detector Alarm

A motion detector alarm could appear excessive to some, but, as any solo adventurer who has faced a frightening situation will share, it’s preferable to err on the side of caution. This compact, lightweight infrared motion sensor occupies minimal space and is easy to set up as soon as you arrive. The alarm will trigger if motion is detected, deterring uninvited guests and waking you (if you’re present in the room); if you’re out exploring, the alarm will likely alert nearby staff of a potential breach. Just remember to deactivate it if you’re aware that housekeeping is on their way — no reason to give them a scare!
