YunTrack CJ220 4G Mini Personal & Vehicle GPS Tracker

🐾 👶 🚗 The Ultra-Compact Multi-Purpose Asset & Personal Safety Guardian That Does It All

Meet the YunTrack CJ220 4G Mini GPS Tracker—a versatile, ultra-lightweight ($40\text{g}$) personal safety and asset tracking terminal engineered specifically for pets, children, elderly relatives, personal luggage, and vehicles.

Combining global 4G LTE cellular multi-band compatibility with quad-constellation satellite tracking (GPS + BDS + GLONASS + Wi-Fi + LBS), a high-capacity 1200mAh rechargeable lithium battery, and multiple power-management operational modes, this compact locator provides continuous safety and position reporting. Supported by the subscription-free YunTrack mobile app for iOS and Android, it delivers real-time monitoring directly to your smartphone.

🛰️ Quad-Constellation Positioning & Real-Time Tracking

• Multi-Mode Location Engine: Combines GPS, BeiDou (BDS), GLONASS, Wi-Fi, and LBS base station triangulation to pinpoint positions accurately both outdoors ($5\text{--}10\text{m}$ precision) and inside buildings.

• Full 4G LTE & 2G Global Network Support: Outfitted with an extensive multi-band modem array compatible with 4G LTE bands across North America, Europe, Asia, and Latin America, backed up by quad-band 2G GSM fallback.

• Geo-Fencing & Historical Route Playback: Set up custom digital safety boundaries on your smartphone map to receive instant alerts if the tracker exits assigned perimeters, and review up to 60 days of movement logs.

🔋 1200mAh Rechargeable Battery & 4 Smart Power Modes

• 1200mAh High-Density Battery Core: Delivers 5 to 7 days of continuous working performance and up to 15–20 days of standby time on a single charge.

  1. Instant / Fast Mode (WKMD,1,30): Real-time tracking uploading location data every 30 to 120 seconds during active use.

  2. Super Power Saving / Roll Call Mode (WKMD,2,0): Ultra-low draw mode that logs position only when manually queried ("roll call") via the app.

  3. Exercise / Motion Mode (WKMD,3,10): Uploads location data every 10 to 1440 minutes while in motion to conserve battery.

  4. Timed Upload Mode (WKMD,4,4): Fixed interval reporting that uploads position every 1 to 24 hours (default: every 4 hours).

🪶 Compact Weatherproof Housing & Multi-Alert Safety System
