Qingping Air Quality Monitor Gen 2: price & specs

The official Qingping store (shop.qingping.co) lists the device as "Qingping Air Monitor 2" at regular price $149.99 USD and publishes the full spec sheet: 7 metrics (temperature, humidity, CO2 400~9999 ppm, PM2.5/PM10 0~999 μg/m³, eTVOC, noise), "4'' IPS touchscreen" at "Resolution: 720 × 720", Mi Home / Qingping+ app over Wi-Fi, and a Lithium Ion "1800mAh/3.7V" battery with "Power port: USB-C" / "Power input: 5V⎓1A" (FAQ: runs "about 3 hours" on battery). Model identity was confirmed via Amazon (ASIN B0CZ85RT6C), which sells the same device in the US as "Qingping Air Quality Monitor Gen 2" with Part Number/Model "CGS2" (Qingping Technology Beijing) — i.e. the global "Air Monitor 2" name equals the US-retail "Air Quality Monitor Gen 2". The dated airpurifierfirst.com hands-on review (9 Dec 2025) corroborates the $149.99 price, the 4-inch IPS touchscreen, USB-C + battery power, and the GrandWay/Sensirion SCD40/SGP40 sensor suite; no radon sensor exists on any source. Release year is not explicitly stated on any fetched page, so release year and release date are left blank.
