Carrying a compact way to draw attention in an uncertain situation can add real peace of mind, whether you're walking home at night, travelling, or just running errands. This safety alarm keychain pairs a 130dB siren with a built-in LED flashlight in a small, clip-on design that attaches to a bag, backpack, or keyring.
Why It Stands Out
✓ 130dB siren — pull the alarm plug to trigger a loud siren meant to draw attention in an emergency.
✓ Built-in LED flashlight — press the button once for steady light, again for a flashing strobe.
✓ USB-C rechargeable battery — a 3.7V 130mAh battery recharges over USB-C instead of needing replacement batteries.
✓ Low-battery alert — the LED flashes and beeps when the charge is running low.
✓ Carabiner clip — attaches easily to a backpack, purse, or keyring for everyday carry.
✓ RoHS certified — meets RoHS environmental and safety compliance standards.
Where It Works Best
This keychain is designed for everyday situations where extra reassurance helps — walking alone at night, travelling, commuting, or spending time outdoors. Clip it to a backpack, purse, or belt loop so it's within reach when you need it.
How the Alarm and Light Work
Pulling the alarm plug out triggers the 130dB siren, which is loud enough that the manufacturer advises against holding it close to your ears. The LED button works independently of the alarm: press once for steady light, press again for a flashing strobe, and a third press turns the light off. A single charge provides about 70 minutes of alarm use, 240 minutes of steady light, or 300 minutes of flashing light.

Setup and Use
1. Charge the unit fully via the USB-C port before first use.
2. Clip the carabiner onto a bag, backpack, or keyring.
3. In an emergency, pull the alarm plug to trigger the 130dB siren.
4. Insert the plug back in to stop the alarm.
5. Press the side button to use the LED as a flashlight — once for steady light, again for flashing, a third time for off.
Care and Storage
Keep the unit dry and avoid dropping it on hard surfaces despite its impact-resistant casing. Recharge fully before long trips, and check the battery level periodically so it's ready when you need it.
