We offer free standard shipping to every province and territory in Canada. No minimum purchase is required, and all orders include tracking for your convenience.
You may return most new, unopened items within 30 days from delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.
Deliveries to Canada’s outer and remote regions may experience seasonal delays caused by severe weather or limited carrier availability. We appreciate your patience and recommend allowing additional time for your order to arrive safely.
Meet the HAKINAKU 3-in-1 Plug-in CO Detector, a compact environmental monitor that blends carbon monoxide detection with temperature and humidity sensing. With a 2-second refresh, it shows real-time data on a bright HD screen, helping you gauge room safety at a glance.
Designed for plug-in convenience, it fits standard US outlets (110–240V) and can be placed in bedrooms, living rooms, kitchens, hotel rooms, offices, or RVs. When power is interrupted, a built-in 1000 mAh rechargeable battery keeps the device operational for up to 90–96 hours, providing a cushion during outages and eliminating frequent battery changes.
Key sensor and alert features include a UL2034-compliant CO sensor, an audible 85 dB alarm, and a broad data range that covers CO from 0 to 999 ppm, a temperature span from 14°F to 122°F, and humidity from 0 to 95% RH. The combination of these sensors gives a clear view of environmental conditions and highlights potential hazards in real time.
What this can do for you: the device offers quick readings at a glance, clear alarms when readings diverge, and a portable option thanks to the onboard battery. It is a practical addition for homes that prioritize comfort, safety, and awareness of indoor conditions.
