The Safety Alarm Keychain is a must-have self-defense accessory for peace of mind wherever you go. Featuring a powerful 120dB alarm and a 40-lumen LED front light with two modes-constant and flashing-this compact tool is easy to use in any situation. To activate the alarm, simply pull the top pin, and to stop it, reinsert the pin. The built-in carabiner makes it easy to attach to keys, bags, or backpacks, so it's always within reach. The rechargeable battery lasts up to 1.5 hours with both the alarm and flashing light, 5 hours with the flashing light only, and 2 hours with constant light. The keychain comes with a micro-USB charging cable, and it fully recharges in just 1.5 hours.
