Product & Technical FAQs

This is a fully portable unit designed for versatile deployment. You can hang it from your tent ceiling or backpack using the included premium leather lanyard. Alternatively, use the heavy-duty magnetic backplate to snap it instantly onto metal surfaces like RV fridges, van walls, or garage toolboxes.

Our detector tracks dangerous Carbon Monoxide (CO) levels from 0 to 1000 PPM. The Pro Edition also tracks Carbon Dioxide (CO2) from 400 to 5000 PPM. Additionally, all editions monitor ambient Temperature and Humidity in real-time. Please note: This device does not detect combustible gases like Natural Gas or Propane.

The unit is powered by a massive 2000mAh built-in lithium core. A single full charge via the Type-C port provides between 150 to 340 hours of continuous standby monitoring. Using the built-in ≥100 lumens LED flashlight frequently will decrease the total standby time.

The device operates on strict threshold metrics. For CO: 0-50 PPM is the normal safe zone (green screen). 51-100 PPM triggers a pre-alert (yellow screen, 3 beeps/min). Anything above 200 PPM is critical, triggering a bright red screen and a piercing 85dB continuous audio alarm to wake you from deep sleep.
