Personal alarm buying guide
Updated: 20.10.2026
You are walking the last ten minutes home, and the amazon.co.uk titles shout 140 dB and police approved. A personal alarm buying guide has to get past that line before you spend between about £6.78 and about £19.99. On the shelf on 19 October 2026 is a small carried siren: a pull pin, a button, or both. It is not an NHS telecare pendant, and it is not a house alarm. The [pocket alarm comparison](/hub/burglar-protection/pocket-alarm) ranks the twelve listings and holds the prices. This page is the checks: one hand, a power plan, and what those approval words do not mean.

What you are actually buying
A pocket alarm is a battery siren you carry. You start it, it makes a continuous noise, and you use those seconds to move towards other people. The NHS page on personal alarms describes a monitored button for someone who may fall at home. None of these keychains phones a call centre. A home burglar alarm stays on the building.
The Suzy Lamplugh Trust’s out-and-about advice is the practical test. The sound should be continuous, and you should start it with one hand. A pin that needs two hands, which one Powbee reviewer reported, fails when the other hand is holding a bag. Rehearse the action before you compare colours.
Loudness without a lab report
The Trust points shoppers to a continuous sound over 130 dB, and it describes about 138 dB as ideal. That is guidance, not a measurement of these twelve listings. Powbee’s specification says 140 decibels, while a bullet says 150 dB and 225 metres, against 100 metres in the table. Original Defense in black is listed at 125 dB and about £17.99. Magenta and mint say 130 dB, and magenta is about £14.99. Use the specification line.
The Health and Safety Executive’s workplace peak limit is 140 dB(C) at the ear under the Control of Noise at Work Regulations 2005. That rule is about workers, not a test of these alarms. Do not demonstrate one beside an ear. Test once, outdoors, pointed away, for a second, then stop it.
Power, pin, and where it clips
LR44 packs, such as Powbee at about £12.86 and SUNMAY at about £15.99, use replaceable button cells. That fails if the cells are already flat, which Powbee reviewers mention. USB models, including Hion, Vantamo, TECKNET, and the Mosaic Alarm PA98CH, move the chore to a cable. Hion’s black page says Corded Electric in one field and lithium-ion in another. That is not a mains alarm. The Mosaic Alarm PA68LED bullet says the cells are sealed, while the specification line says two C cells.
Hion’s bullet says IP44. TECKNET’s title says IPX4. Both are splash ratings. Original Defense says water-resistant and prints no IP code. A clip only helps if the unit is in your hand or on a strap you can grab. The sequence once you own one is on the how to use a pocket alarm page.
When police approved is real
Secured by Design explains Police Preferred Specification as an independent test plus factory checks. Personal attack alarms on that scheme are cited to Sold Secure SS502, and the names in police travelling advice include Minder and Defender. None of these twelve listings shows that code. A title that says police approved, which Powbee and Hion both use, is a seller’s phrase. If a university or an employer has asked for the mark, leave this set. This page does not record a Minder or Defender price.
Prices on 19 October 2026 run from about £6.78 to about £19.99. A three-pack can look cheaper per unit and still hand someone a silent alarm. Test every unit you will give away.
Which check decides the buy
If you cannot start it with one hand, or you will not keep the cell ready, the decibel line does not matter. If a buyer has asked for Sold Secure SS502, this shelf is the wrong one. If you are staying here, choose a pin or button you have rehearsed, a power plan you will actually keep, and a water code only when the page prints one. Then use the comparison for the price.
Common questions
How loud should a personal alarm be?
The Suzy Lamplugh Trust points shoppers to a continuous sound over 130 dB, and about 138 dB as ideal. That is guidance, not a measurement of these listings. Specification lines run from 125 dB on black Original Defense to 140 dB on Powbee, SUNMAY, and Fauxomor. The Mosaic Alarm PA98CH lists 135 dB. Prefer the specification line over a louder bullet, then listen once, away from your ears.
Can I set it off with one hand?
You should be able to. Hion offers a pin or a double-press. TECKNET uses a double-click. Vantamo’s specification only says Touch, so do not assume a pin. One Powbee review says the pin needed both hands. Try the action at home before you trust it with a bag in the other hand.
Are button cells or a rechargeable unit less likely to be flat?
Neither stays ready if you never look. LR44 packs can arrive with tired cells, which Powbee reviews mention finding too late. A rechargeable unit is flat when you forgot the cable. The Mosaic Alarm PA68LED bullet says the cells are sealed, and reviews include a unit that arrived not working. A short outdoor test beats the chemistry printed under the title.
Is this the same as an elderly-care pendant?
No. NHS personal alarms in social care are monitored buttons, often with a response service and a key safe. The products here are audible sirens. They do not call 999 and they do not call a family member. An older person who needs someone alerted at home wants the telecare product. A siren can still make sense for a walk, if they can start it with one hand and there is a chance someone nearby will hear it.
Does IP44 or IPX4 mean I can use it in the rain?
It means a splash claim, not a soak. Hion claims IP44. TECKNET puts IPX4 in the title. Original Defense says water-resistant and prints no IP code. Most of this set says nothing about water. If rain is the main risk, choose a page that states a code, and still do not soak the unit to find out.
