Carbon Monoxide Alarm 3-in-1
The NESTOUT CO Alarm is a portable carbon monoxide detector designed for camping, road trips, van life, RV travel, and other outdoor adventures. It detects CO generated by charcoal, camp stoves, generators, and fuel burning equipment and alerts you before levels become dangerous.
IP54 dust and water resistant, backlit LCD, foldable rear stand, and USB-C rechargeable with approximately five days of continuous use per charge.
Three Readings on One Screen Three Sensors, One Device
In addition to CO concentration, the backlit screen displays temperature (14°F to 122°F), and humidity (20% to 90% RH) in a single unit. Peak CO tracking captures the highest level reached during each detection cycle so you know exactly what happened while you were away from camp.
Portable Carbon Monoxide Detector for Travel
The detector is compact enough to carry in a camping bag, suitcase, glove compartment, or van storage area. The included storage pouch helps protect it between trips.
Its foldable rear stand provides several placement options. You can set it on a raised table, shelf, or gear container, or hang it using the built-in hook. This flexibility makes it useful as a portable carbon monoxide detector for travel, hotels, cabins, campers, vans, and temporary accommodations.
Rechargeable Power for Longer Trips
A full charge provides approximately five days of continuous operation. The built-in lithium-ion battery recharges through USB-C in approximately 2.5 hours when used with a compatible 5V/1A or higher charger.
You can keep it topped off on longer trips with any NESTOUT power bank or power station.
Where to Place the CO Detector?
Always position above head height, near where you sleep or spend the most time. CO rises with warm combustion gases, and a detector placed too low may not alert you quickly enough. Use the foldable stand on an elevated surface or clip the built in hook to a tent ridge or gear loop. Never block the air inlet on the back of the unit.

Important Safety Info
This product is designed to help detect carbon monoxide. It does not prevent CO exposure, reduce CO levels, or replace proper ventilation. Always ensure adequate airflow when using stoves, lanterns, charcoal, generators, or any fuel burning equipment in enclosed spaces. The CO Alarm is one part of a broader safety practice, not a substitute for ventilation, responsible equipment use, or emergency preparedness. If the alarm sounds, evacuate immediately, ventilate the area, extinguish open flames, and contact emergency services if needed.
Not intended for long term monitoring beyond battery life, use in place of a fire alarm, industrial applications, or regulatory compliance.
