BACtrack keychain breathalyser (black) – ultra‑portable pocket keyring alcohol tester
Small, sensible and dead handy — the BACtrack Keychain Breathalyser is for anyone who wants a quick, fuss‑free read on their blood alcohol level. It clips onto your keys, slips into a pocket or tucks into a bag, so whether you’re heading out for a night, facing a long drive home or finishing a late shift, there’s really no excuse not to check.
What it does
This little gadget estimates your BAC in roughly five seconds and shows the result on a clear two‑digit blue LED screen. The mouthpiece folds away to stay clean, then pulls out for use. Three replaceable mouthpieces are included, so a few people can share it hygienically without worrying.
Key benefits and uses
- Quick reassurance after a drink — see whether it’s sensible to drive or whether you should leave it a bit longer.
- Perfect for designated drivers, groups out socialising, shift workers and anyone who likes to be responsible.
- Handy for workplaces, clinics or schools that want a simple screening tool for personal use.
- Compact enough to forget about — which is the whole point: it goes everywhere with your keys.
It runs on a single AAA battery (supplied) and uses BACtrack’s Advanced MicroCheck sensor technology to produce reliable readings across the 0.00–0.40% BAC range. You can expect around 75 tests per battery depending on use. The device is FDA 510(k) cleared for personal use and comes with a one‑year warranty.
Practical notes and common questions
- Is it legal evidence? This breathalyser is intended for personal use and screening; for evidential or police‑grade testing you’ll need a certified device or official testing.
- How accurate is it? It provides consistent, reliable estimates for everyday decisions — though environmental factors, heavy smoking or very recent drinking can affect results. If unsure, wait a short while and retest.
- Battery and maintenance: takes one AAA battery (included). Replace mouthpieces between users and keep the device dry to prolong its life.
The dimensions are tiny (about 1.5″ x 2.5″ x 0.5″) and it weighs only a few ounces, so it’s genuinely easy to carry. If keeping loved ones safe and avoiding risky choices sounds sensible, this is a straightforward, affordable tool that makes responsible decisions easier. No complicated setup, no tech faff — just clip on, breathe, and know.
