First place on your own, a late walk home, a solo hotel room: a small kit can make those moments feel a bit more manageable.

This list sticks to two jobs. A personal alarm makes noise and light when you pull the pin, and door gear adds a layer on doors you can't change, like a rental or a hotel room. Nothing here is a guarantee of safety, and none of it replaces calling for help. There are no weapons or sprays on this list, either. The picks come from BestReviews, NBC Select, Pack Hacker and Bob Vila, and we only repeat what those outlets say. Each card shows the drawback too, like alarms that can go off by accident in a bag or a jammer that takes minutes to set up.

Who this is not for. Skip this if you're after smoke alarms and first aid for the whole home; the Home Safety list covers those.

Questions people ask

Can a personal alarm go off by accident?

Yes, so think about where you keep it. NBC Select's reviewer had a Birdie turn on without being activated, and BestReviews warns the Kimfly can activate by accident in a purse or backpack.

Will a portable door lock get flagged at the airport?

It might. Shop TODAY warns that the portable door lock in its solo travel guide may be flagged in an airport security screening and may not fit cruise cabin doors, and Pack Hacker says the Addalock may take some explaining at airport security. Plan for that before you pack one.

Which door gear fits which door?

Check your door first. Bob Vila says the Sabre wedge suits inward-opening doors with less than an inch of floor gap, the DoorJammer needs a quarter inch of gap under the door, and the Master Lock bar works on both hinged and sliding doors.

Why no pepper spray on this list?

This list only covers alarms and door gear. If you're weighing spray, an expert in NBC Select's guide warns that wind, enclosed spaces, sunglasses or masks and adrenaline can all reduce how well it works.
