EVA’s alarm reaches 130 dB at 30 cm — about as loud as a jet engine heard from 30 metres. It’s piercing enough to disorient someone up close and pull attention from across a street, platform or car park.

Yes. The 130 dB alarm and the built-in flashlight work entirely on their own — no phone, no app, no signal needed. You only pair a phone if you want the extras: one-tap emergency calling and live location sharing.

A full charge lasts several weeks of everyday carry. EVA recharges over USB-C in a couple of hours, and a quick top-up is enough to see you through the week — so it’s ready whenever you are.

Only the emergency contacts you choose, and only when you start a share or trigger an alert. EVA doesn’t track you in the background — your location stays private until you decide to send it.

Setting EVA off takes a deliberate press-and-hold rather than a single tap, so it won’t fire on its own in your bag or pocket. If it ever does, you can cancel it in seconds — no false alarms on the bus.

EVA is splash- and rain-resistant, so everyday carry, a sudden downpour or a sweaty run are no problem. It isn’t designed for swimming or being fully submerged.
