• Long Battery Life & Fast Charging: This portable carbon monoxide detector is equipped with a 1000mAh rechargeable battery and supports Type-C fast charging. It takes only 1.5 hours to fully charge and provides up to 200 hours of standby time, making it reliable for everyday use and long-distance travel without frequent recharging. A practical choice for both a home CO detector and a travel carbon monoxide detector
• Accurate 3-in-1 Monitoring: Designed for precision, this compact CO detector combines three functions in one: carbon monoxide detection (0–999 ppm), temperature monitoring (14–140℉ / -10–60℃), and humidity detection (0–99% RH). Whether used indoors or outdoors, it delivers real-time data so you can always stay aware of air quality
• Clear LCD Display with Smart Alarms: Featuring a bright LCD screen, this carbon monoxide detector uses an easy-to-read three-color system: green (safe: 0–49 ppm), yellow (warning: 50–99 ppm with a low-frequency beep), and red (danger: ≥100 ppm with a high-frequency alarm). The loud alarm ensures timely alerts, while the customizable threshold can be adjusted in 5 ppm steps (0–995 ppm). Default alarm threshold: 50 ppm. Perfect as both a portable CO detector for travel and a reliable carbon monoxide detector for home safety
• Portable Design with Magnetic Back & Lanyard: Compact and lightweight, it comes with a lanyard and built-in magnet for flexible use in tents, cars, RVs, boats, hotels, or at home. Easily attach it to metal surfaces or place it in bedrooms, kitchens, and basements. Perfect as a portable or backup RV carbon monoxide detector—ideal for camping, road trips, or hotel stays.
• User-Friendly Operation: Simple to operate: press once to switch between °C and °F, press twice to mute or activate the alarm, and press three times to set custom thresholds (increasing 5 ppm each time). After 5 seconds, the unit automatically returns to normal monitoring. (Note: A 30-second countdown runs at startup before normal operation begins.) Compact yet versatile, it can also be used as a car carbon monoxide detector
• Package Includes: You will receive one rechargeable carbon monoxide detector, one Type-C charging cable, one lanyard, and one user manual. If you have any questions or need assistance, our professional customer service team is always ready to help
