Door Stop Alarm, 120 dB Siren, Battery Operated Wedge Alarm for Hotels, Airbnbs, Dorms, No Installation Needed, Portable Travel Door Security for Solo Travelers

You’ve already tested the deadbolt. You’ve checked the chain lock, even though you know it wouldn’t stop much. Now you’re lying there running through worst-case scenarios about how many master keys exist for this room. That’s not paranoia — that’s just what happens when you sleep somewhere you don’t control the locks.

Who This Is Best For
This is built for solo travelers checking into hotels solo, people staying in Airbnbs where you’ve never met the host, college students in dorms with thin doors and shared hallways, and anyone who wants an extra layer of certainty before they fall asleep in an unfamiliar place.

Why This Is the Right Call
If your main worry is someone getting through a door quietly while you sleep, this solves that specific problem. It doesn’t require drilling, adhesive, or messing with hotel property — you wedge it, you sleep, you pack it and go. If you need something that works the moment you walk into a room with zero setup, this is it.

FAQ

Will it work on any hotel door?
Most standard doors have enough gap at the bottom for the wedge to sit snug. Doors that sit flush against thick carpet may need testing first. It’s a good idea to check the fit as soon as you get to your room.

How loud is 120 dB really?
That’s roughly as loud as a car horn from a few feet away — loud enough to wake you from sleep and loud enough that anyone in the hallway will hear it too.

Do I need tools or tape to set it up?
No. Just slide it under the door with the sensor pad against the floor. No adhesive, no drilling, no leaving marks on hotel or rental property.

Does it come with batteries?
Yes, batteries are included and ready to go out of the box, so you can use it the first night without a trip to the store.
