Sylzy 2-Pack 4-in-1 CO Detectors & Natural Gas Alarm – Plug-In with Battery Backup

Meet the Sylzy 2-Pack: 4-in-1 Detection for Home and Travel

This compact, plug-in pair combines carbon monoxide detection, natural gas detection, and environmental readings in one convenient unit. Designed for 110V–220V outlets, they fit comfortably in kitchens, bedrooms, living spaces, RVs, apartments, and hotel rooms, providing around-the-clock awareness without clutter.

Power You Can Rely On

Each detector includes a built-in 1000mAh rechargeable battery, keeping monitoring active during power outages for up to 10 hours. A USB charging cable is included for simple recharging at home or on the go—ideal for travel, camping, or areas with unstable electricity.

Clear, Real-Time Data You Can Read at a Glance

The large digital display shows CO concentration (PPM), gas status, temperature (°F/°C), and humidity (%RH). You can adjust brightness with four levels (high, medium, low, off). When the display is dimmed or off, a status light blinks every 5 seconds to confirm ongoing monitoring.

Smart Sensing for Fast, Local Awareness

Equipped with an electrochemical CO sensor and a catalytic gas sensor, readings refresh every 2 seconds. They detect common gases such as methane, LPG, propane, and more, with ±5℃ temperature accuracy and ±5%RH humidity accuracy.

Audible and Visual Alerts

When CO or gas is detected at concerning levels, an 85dB alarm sounds and the display flashes, ensuring alerts are noticeable in busy rooms or during the night.
