Protmex Portable 4-in-1 Carbon Monoxide and CO2 Detector
Traveling often means sacrificing knowledge of your immediate environment, which is why I tested the Protmex 4-in-1 Carbon Monoxide and CO2 Detector. This sleek device aims to bridge that gap by providing constant, reliable air quality monitoring in a package small enough to fit into any carry-on.
Performance & Build Quality
The device feels surprisingly robust despite its mini form factor, with a build that suggests it can withstand the rigors of being tossed into a luggage compartment. The magnetic suction feature is a standout, allowing for secure placement on metal surfaces, while the internal 1000mAh battery delivers impressive longevity for long trips.
Day-to-Day Experience
Setting up the monitor is straightforward, and the audible alarm provides a clear, immediate warning if air quality parameters are exceeded. Its Type-C charging capability ensures that keeping the unit topped up is as simple as charging your smartphone, making the learning curve virtually non-existent.
This is a must-have for digital nomads, frequent business travelers, and anyone staying in varied indoor environments who wants to ensure their breathing space is safe.
Final Thoughts
