Personal safety alarms (2026)
A personal safety alarm is a small siren you set off by pulling a pin or pressing a button, to draw attention and help you get away. Many add a strobe or flashlight for walking after dark. Loudness figures are the makers' own. Specs are from the makers' pages or, where there isn't one, a review, read on the date in each card's notes; we haven't used these ourselves.

ⓘ As an Amazon Associate, PreparedStates earns from qualifying purchases. We may earn a commission when you buy through our links. When two products are close, commission can decide which one we pick. A clearly better product always wins. Amazon prices come from Amazon's own product data and can change at any time.
Before you buy
Pull-pin alarms are the fastest to set off; push the pin back in to stop most of them.
Loudness is quoted in decibels by the maker: 120 to 140 dB here.
These are the makers' own figures, not independent measurements.
Power: rechargeable (She's Birdie 3.0, Disc) or replaceable coin cells (Birdie original, Fauxomor).
Light: a strobe draws attention; a flashlight or LED running light helps you see and be seen.
Packs of three are handy for a household; check the listing for pack size.
We verify every product's specifications against at least two independent sources, re-check its US price and stock on a schedule where we can track it automatically, and cross-check safety-relevant claims against official guidance. Every review is labeled Researched or Used and reviewed by us: where we've bought a product, or been sent it free, and used it ourselves, its review says which; where we haven't, our verdict is a considered spec-and-evidence comparison, not a hands-on test. When two products are close, commission can decide which one we pick. A clearly better product always wins. Read our full methodology →

Common questions
How loud is a personal alarm?
Makers list 120 dB (SABRE) to 130 dB (She's Birdie); Fauxomor's seller claims 140 dB, which some users doubt.
How long does the siren last?
She's Birdie says the original sounds for about 40 continuous minutes on a new set of batteries; a review of the Fauxomor says up to 60 minutes.
Does an alarm replace calling 911?
No. It draws attention from people nearby. Call 911 as soon as you can.
Rechargeable or replaceable battery?
Rechargeable saves buying cells but needs remembering; coin cells last a long time sitting on your keys. Pick the one you'll keep up with.
