Door Stopper – Portable Security Jammer with Optional 80dB Alarm

Add a secondary layer of resistance to a compatible inward-opening door with this portable Door Stopper from Idiello.com. Its aluminium-alloy structure braces the door against the floor, while rubber suction components help maintain grip on suitable smooth surfaces.

Compact, lightweight and quick to install without tools, it is convenient for hotels, apartments, dormitories and travel. Selected versions include a sensitive vibration sensor and an approximately 80dB alarm to alert occupants when the door is disturbed.

Key Features of the Portable Door Stopper

Heavy-Duty Aluminium-Alloy Construction

The main structure is made from robust aluminium alloy to resist everyday pressure, bending and deformation. It provides more substantial reinforcement than a basic lightweight rubber wedge.

The device is intended as a supplementary barrier and does not make a door impossible to open.

Rubber Suction-Cup Grip

Depending on the selected style, the product includes one or two rubber suction cups that help grip a suitable floor.

Performance is best on surfaces that are:

• Smooth
• Clean
• Dry
• Flat
• Non-porous

Suction may be reduced on carpet, uneven tile, textured wood, dusty floors or wet surfaces.

Optional 80dB Alarm

Alarm-equipped models contain a vibration sensor that detects movement or pressure against the door. When triggered, the approximately 80dB alarm can alert the occupant and discourage continued interference.

Standard versions do not include the alarm function. Confirm the selected variation before ordering.

2-in-1 Security Function

Alarm models combine:

• Physical resistance against door movement
• An audible vibration alert

This gives travellers both a mechanical door brace and an immediate warning when the door is disturbed.

Portable and Travel-Friendly

The compact design fits inside many:

• Handbags
• Backpacks
• Suitcases
• Carry-on bags
• Travel organisers
• Larger coat pockets

Its portable construction makes it useful for temporary accommodation where permanent installation is not possible.

Tool-Free Installation

No drilling, screws or permanent alteration is required. Position the device correctly, engage it against the floor and remove it with an upward motion when leaving.

Always practise removal before relying on the product during travel.

Multiple Styles Available

Choose from the listed configurations:

• One-piece standard door stopper
• One-piece door stopper with alarm
• Single suction-cup standard model
• Single suction-cup alarm model
• Double suction-cup standard model

The exact appearance and included features depend on the selected variation.
