Frequently Asked Questions

Q: How loud is the personal safety alarm, and how far can it be heard?

A: The alarm produces a 130-decibel siren — comparable to a jet engine at close range — that can attract attention from people up to 500 meters away, making it highly effective in crowded or open spaces.

Q: How do I activate the safety alarm keychain?

A: There are two activation methods: pull the safety pin out of the device, or press the dedicated SOS button. Either method immediately triggers the 130dB siren. To stop the alarm, reinsert the pin or press the button again.

Q: How long does the battery last, and how do I recharge it?

A: On a full charge (approximately 2 hours via the included Type-C cable), the alarm can sound continuously for up to 40 minutes, and the flashlight runs for up to 3 hours in steady mode. In standby mode, the 80mAh lithium battery lasts over 2 years. A low-battery warning (white LED flash + beep) alerts you when the charge drops below 20%.

Q: Can I carry this alarm on a plane or through transit security?

A: Yes — this alarm is designed to pass through subway, train, and vehicle security checks without issue. For air travel, it must be placed in checked luggage rather than carried on board.

Q: Is this alarm suitable for children and seniors?

A: Absolutely. Weighing just 20g and featuring simple one-touch or pull-pin activation, this keychain alarm is easy for people of all ages and abilities to use quickly and confidently.
