FILINK 4-in-1 Portable CO Detector for Travel — 300H Battery, Temp & Humidity Monitor, Emergency Flashlight

Compact safety, powerful insight

Meet the FILINK 4-in-1 Portable CO Detector, a travel-ready device designed to keep you informed without weighing you down. Real-time readings, trustworthy alarms, and practical features come together in a small package that travels as easily as you do. Whether you’re camping, cruising in an RV, staying in a hotel, or cooking in a kitchen with shared ventilation, this detector offers a balanced blend of visibility and reliability.

What it measures

• CO concentration from 0 to 1000 ppm
• Ambient temperature from -10°C to 55°C
• Relative humidity from 0% to 100% RH

This multi-parameter monitoring supports a clear view of environmental conditions, helping you respond to potential air quality changes with informed choices.

Smart alarms you can trust

• Four-level visual indicators (green, yellow, orange, red) paired with audible alerts
• Immediate signaling when readings breach preset safety limits

The layered alert system is designed to convey danger levels at a glance and audible cues to supplement visual feedback, so you can act promptly if needed.

Travel-ready design

Designed for life on the move, it measures 3.82 x 2.2 x 1.18 inches and weighs about 3.81 oz. A built-in lanyard and a magnetic back add flexible placement options for bags, vehicles, or kitchen counters.

Power that lasts

• 2000 mAh built-in battery delivers up to 300 hours on a full charge
• Automatic power-saving mode engages after one minute of inactivity

Long battery life reduces the need for frequent recharging during trips, while smart power management helps extend overall usage between charges.

Practical nighttime and control features

• Emergency flashlight with high and low brightness settings
• Temperature unit switching between °C and °F for convenient readings

The flashlight feature adds nighttime usability in dim environments, and the temperature option ensures readings match your preferred unit system for easy interpretation.

Precision in challenging spaces

High-precision sensors rapidly detect CO levels, making it suitable for less-ventilated areas such as garages, fireplaces, or gas heater zones where air quality matters.

Important note on measurements

This detector measures carbon monoxide concentration, not carbon dioxide. CO readings can rise under combustion or gas-leak conditions, so use as part of a broader safety routine.

In real-world scenarios, this device aims to offer useful visibility into air quality and potential risk moments, presenting possibilities rather than guarantees. It’s best used as a proactive safety aid alongside other precautions and local guidelines.
