TS21 Portable Door Stopper Alarm - Travel Security Lock for Hotels

A locked door isn't always a secure one.

Staying in hotels, rentals, or unfamiliar spaces can leave you uncertain about door security — especially when you have no control over who has access to a key. Standard door locks provide basic protection, but they offer no alert if someone attempts to open the door while you're inside, and no physical backup if the lock is bypassed.

Fits into any bag, luggage, or carry-on without adding noticeable weight. Place it under the door before bed, activate the alarm, and sleep with the confidence that any attempt to open the door will be both physically resisted and immediately announced. Designed for solo travelers, business travelers, and anyone who wants a simple, reliable layer of security in any accommodation.

The TS21 Portable Door Stopper Alarm is designed to add a second layer of security to any inward-opening door — combining a physical wedge that blocks entry with an 80dB alarm that activates the moment pressure is applied to the door.

Why it works

• Dual Protection System — acts as both a physical door blocker and an audible alarm deterrent simultaneously
• 80dB Alarm — activates within seconds when pressure is applied to the door, providing an immediate alert
• Premium Aluminum Alloy Build — durable and lightweight at 0.4 kg, built for daily travel use
• Universal Door Compatibility — works on inward-opening doors with a 5–35mm gap across tile, wood, marble, and more
• No Installation Required — simple wedge-and-activate design, ready to use in seconds
• Ultra-Portable — compact enough to fit in any bag, luggage, or carry-on

Who it's for

Ideal for solo travelers, business travelers, students in dorms, and anyone staying in hotels, vacation rentals, or temporary accommodations who wants added peace of mind at night.
