DESIGNED WITH INTENT

Everything you need. Nothing you don't.

Every detail of Havyn One is engineered to be reliable when it counts and invisible when it doesn't.

130 dB emergency siren

As loud as a military jet at take-off distance — engineered to cut through street noise and be heard from far away.

High-visibility LED strobe

A bright flashing strobe activates with the siren, making you visible in low light, at night or in crowded spaces.

Built-in flashlight

A practical everyday flashlight for dark car parks, doorways and paths — useful long before you ever need the alarm.

USB-C rechargeable

Charges with the same cable as your phone. Months of standby on a single charge — no batteries to buy, ever.

Pull-pin activation

One firm pull and the alarm sounds — no buttons to find, no sequences to remember. Reinsert the pin to reset instantly.

Safety switch

A discreet lock reduces accidental activation in your bag or pocket, so it only sounds when you mean it to.

Splash-resistant

Rain, spills and everyday weather won't stop it. Built to live on your keys through every season.

Travel-ready

Compact, lightweight and TSA-friendly*, so it goes wherever you do — from the daily commute to long-haul trips.

*Subject to current airline and security regulations. Always check before you fly.

HOW IT WORKS

Four steps. Zero learning curve.

01

Attach

Clip it to your keys, handbag, backpack or luggage with the reinforced keyring.

02

Carry

Take it everywhere. At under 40 grams, you'll forget it's there — until you're glad it is.

03

Pull

If you need immediate attention, pull the pin. The 130 dB siren sounds while the strobe flashes.

04

Reset

Reinsert the pin and the alarm stops. Fully reusable — test it, use it, reset it, repeat.

QUESTIONS, ANSWERED

Everything you'd want to know.

How loud is 130 dB, really? +

130 dB is comparable to a jet aircraft heard from around 100 metres, or a loud rock concert. It's designed to be impossible to ignore and audible from a significant distance, even over traffic and street noise.

How do I activate and reset it? +

Pull the pin firmly — the siren and strobe activate immediately and continue until the pin is reinserted. No buttons to find, no sequences to remember.

Can I test it safely? +

Yes — and we encourage it. Test it briefly outdoors, away from your ears and pets. Pull the pin, confirm the siren and strobe work, then reinsert. A short test won't meaningfully affect battery life.

Will it go off accidentally in my bag? +

The pin requires a firm, deliberate pull, and the safety switch adds a second layer of protection against accidental activation while it's in a bag or pocket.

How long does the battery last and how do I charge it? +

Months of standby on a single charge. Charge with the included USB-C cable — a full charge takes about an hour. A monthly top-up is a good habit. No disposable batteries, ever.

Is it waterproof? +

It's splash-resistant — rain, drizzle and everyday spills are fine. It shouldn't be submerged or worn while swimming.

Can I fly with it? Is it legal to carry? +

Personal sound alarms are legal to carry in virtually every country — unlike sprays, which are restricted in many places. Small lithium batteries are typically permitted in carry-on luggage; always check current airline rules before you travel.

Will it fit on my keys or bag? +

Yes — the reinforced metal ring attaches to any key ring, bag hardware, zip pulls, straps and luggage. It's smaller than most car key fobs and adds under 40 g. Keep it somewhere you can reach with one hand.

How long does shipping take? +

Orders dispatch within 24–72 hours on business days, with tracked delivery of 2–3 weeks to South Africa. Every order includes tracking, and any customs fees are covered by us — the checkout price is final.

What is your return policy and warranty? +

30 days, no questions asked — return it for a full refund. Every Havyn One also includes a 2-year warranty covering manufacturing defects.

Is there a subscription or app? +

No. Havyn One is a one-time purchase. No app, no account, no monthly fees — it simply works.

Can I buy it as a gift? +

It's one of our most common purchases — for daughters, parents, new students and frequent travellers. The Duo 2-Pack was made exactly for this: one for you, one for her.

Questions, answered

How loud is 130 dB?

About as loud as a jet heard from 100 m — impossible to ignore and audible across streets, garages and parking lots.

How does it work?

Pull the pin and the siren plus flashing strobe activate instantly. Reinsert the pin to stop and reset — fully reusable.

How long does the battery last?

Months of standby per charge. It recharges with the included USB-C cable — no batteries to buy, ever.

Will it go off in my bag?

The pin needs a firm, deliberate pull, so accidental activation is very unlikely in a bag or pocket.

How long is delivery?

Tracked delivery to South Africa in 2-3 weeks. Any customs fees are covered by us — the checkout price is final.

Is there a discount for buying more than one?

Yes — add 2 or more to your cart and 20% comes off automatically at checkout. One for your keys, one for your partner, your teenager or your mom.
