Overview
The GPT48-X is a 4G asset tracker designed for logistics and asset protection. Powered by an 8000 mAh lithium-manganese battery with zero self-discharge, the device can report a location heartbeat once per day for up to five years. Supporting LTE-M and NB-IoT networks, and using multi-constellation GNSS (GPS/BeiDou/GLOSNASS) with fallback to LBS and Wi-Fi positioning, GPT48-X delivers reliable connectivity and accurate tracking anywhere in the world. Its built-in motion sensor wakes the device when vibration is detected and supports remote wake-up by SMS, allowing it to switch from low-power mode to real-time tracking during emergencies. Rugged magnetic mounting makes installation quick and easy, while multi-layer alarms (vibration/drop/collision, geofence, tamper and low battery) ensure assets are protected. The tracker integrates seamlessly with Eelink’s cloud platform and third-party systems, and supports over-the-air (OTA) firmware updates.
Key Features
- Ultra-long battery life – 8 000 mAh lithium-manganese battery with zero self-discharge provides up to five years of standby with one daily heartbeat. The device intelligently switches to low-power mode when idle and can be woken remotely by SMS.
- Low-power network connectivity – Supports LTE-M and NB-IoT networks for low-power, low-cost communication, with fallback to 2G where available.
- Precise positioning – Uses multi-constellation GNSS (GPS/BeiDou/Glonass) for fast, accurate location fixes with 2 m typical accuracy. When satellites are unavailable the device falls back to LBS and Wi-Fi positioning for continuous tracking.
- Intelligent sensors and alarms – Built-in motion and vibration sensors detect movement and support wake-up on motion. Multi-layer alarms notify of vibration, drop, collision, tamper and low battery events. Geo-fence and route deviation alarms can be configured via the platform.
- Remote configuration & OTA updates – Work modes and reporting intervals can be configured remotely via SMS or the management platform. Over-the-air firmware updates keep the device secure and add new features.
- Flexible working modes – Long-standby mode reports location periodically (e.g. once per day) for years, while emergency real-time mode increases reporting frequency for accurate tracking when an incident occurs.
- Rugged magnetic design – Compact and waterproof (IP67) housing with built-in industrial magnets allows easy attachment to metal surfaces such as containers, trailers and heavy equipment. Device dimensions are approximately 101.3 × 60.3 × 25.5 mm and weight is about 130 g.
- Platform integration – Compatible with Eelink 2.0 management platform and third-party systems. Data can be viewed on dashboards, exported, and integrated into logistics software via APIs.

Typical Applications
- Long-haul trucking and trailer management – Attach GPT48-X to trailers or tractor units to monitor location, motion and security during long journeys. The device’s long battery life supports multi-year deployments without maintenance; remote wake-up means it can switch to real-time tracking during theft or hijacking events.
- Shipping containers and pallets – Securely magnetically mount the tracker to shipping containers, pallets or totes to monitor location across supply chains and improve visibility of ocean and intermodal shipments. Geo-fence alarms can detect unauthorised movements.
- Railcars & heavy equipment – Track railcars, excavators, generators and other heavy equipment to prevent theft and manage utilisation. Vibration and tamper alarms send alerts if equipment is moved unexpectedly.
- High-value assets – Deploy the tracker on high-value assets such as mobile power units, rental equipment or telecom enclosures to provide security and asset management.
- Smart agriculture & livestock – Use the tracker on livestock trailers, farm equipment or containers to monitor location and ensure animals or cargo stay within designated boundaries.
- We recommend using multiple trackers across large fleets to improve visibility, reduce losses and enhance operational efficiency. The device’s multi-year battery life and minimal maintenance requirements deliver total cost ownership advantages. advantages.
Installation & Operation
- Mounting – Ensure the device is fully charged and insert a nano SIM card. Affix GPT48-X to a clean metal surface using the built-in magnets or optional bracket. For non-metal surfaces, use adhesive or secure mounting hardware.
- Power on & work mode – Press and hold the power button until the indicator flashes to power on. The device will enter long-standby mode by default, reporting location at the configured interval.
- Configuration – Configure reporting intervals, geo-fences and alarms via the management platform or by sending SMS commands to the device. Switch to real-time mode during emergencies by sending a wake-up SMS; the device will increase reporting frequency but reduce battery life accordingly.
- Monitoring & alerts – View location history, battery status and alarms on the web or mobile app. Set up email/SMS notifications for geofence breaches, vibration/drop events, or low battery.
- Maintenance – When battery runs low, follow the manual to replace the battery or recharge if supported. Perform OTA firmware updates regularly via the platform.
