HAKINAKU 5in1 Plug-in Smoke, CO & Natural Gas Detector with HD Screen and Built-in Battery

HAKINAKU presents a compact, all-in-one safety companion designed for home, hotel rooms, and travel. The 5in1 Plug-in Detector combines carbon monoxide, smoke, combustible gas, temperature, and humidity sensing with a crisp 2.1-inch HD display. Real-time data and clear indicators empower you to understand conditions at a glance, helping you respond quickly and calmly when needed.

What it monitors

• Carbon monoxide with color-coded states: green for safe, yellow as a caution, red when elevated risk is detected.
• Combustible gas with a similar alert scheme, covering common indoor gases used in kitchens and heating.
• Smoke presence with a green safe state and red, continuous alarm if smoke is detected.
• Environmental readings for temperature and humidity displayed alongside gas and smoke indicators.

The detector also emits audible alerts to accompany the visual icons, delivering timely cues even in busy spaces. The goal is to provide clear, actionable information without overwhelming you with data.

Ease of use and real-life utility

• Plug-in design compatible with US outlets (110V–220V), so installation is quick and seamless in bedrooms, kitchens, living rooms, or hotel rooms.
• Built-in 2000 mAh battery supports 18–20 hours of backup power, helping maintain alerts during short outages.
• Large, legible 2.1-inch HD screen updates in real time for CO, smoke, gas, temperature, and humidity.
• 85 dB audible alarm ensures you can hear warnings even when you’re not directly by the device.

In daily life, you’ll notice the big, color-coded icons and the steady stream of data that makes it easier to assess a room’s safety at a glance. Independent sensors for smoke, CO, and combustible gas help deliver reliable readings, while the built-in battery reduces the need for frequent replacements and keeps the device functioning when power is interrupted.
