Protmex Portable 4-in-1 Carbon Monoxide & Dioxide Detector
Choice!
Safety is the most important part of any camping trip, yet many of us overlook air quality inside our tents or cabins. I put the Protmex Portable 4-in-1 Carbon Monoxide Detector to the test to see if it could provide peace of mind without adding unnecessary bulk to my pack.
Performance & Build Quality
This device feels impressively robust for its small size, featuring a sleek housing that is easy to handle with cold hands. The magnetic suction is a clever addition, allowing it to stick securely to any metallic surface, making it perfect for securing inside a vehicle or near a heater.
Day-to-Day Experience
Setting up the unit is nearly instantaneous, and the Type-C charging makes it easy to keep topped up between outings. I found the 48-hour battery life more than sufficient for weekend trips, and the audible alarm is loud enough to wake a heavy sleeper in an emergency.
This is the perfect safety companion for outdoor enthusiasts, van lifers, and anyone who uses portable heating or cooking equipment in confined areas.

The Protmex Portable 4-in-1 Monitor earns its 4.92/5 rating by delivering consistent, accurate data in a highly portable form factor. For $59.00, it is a small price to pay for the security of knowing your environment is safe wherever you wander in 2026.
