The GPT50 is an ultra‑long GPS tracking device engineered for years‑long in‑transit monitoring of assets, vehicles and cargo. Powered by a massive 24 000 mAh battery and power‑efficient electronics, it offers up to 10‑year standby with once‑daily reports. GPT50 leverages multi‑constellation GNSS (GPS, GLONASS, BeiDou and Galileo) and communicates via LTE Cat‑1 with 2G fallback for global coverage. Weighing approximately 350 g (±10 g), it is IPX7 waterproof, operates from −20 °C to +60 °C and is ideal for long‑term deployment on trailers, containers and other valuable assets requiring reliable, real‑time visibility and security.
Here are the reasons why the GPT50 is in a league of its own for asset tracking:
The GPT50 is engineered specifically for pallet pools – its recessed housing sits flush under Euro and CHEP pallets, fixed securely with four M4 screws. This hidden, impact‑resistant design meets ISO 17366 requirements and protects the tracker from damage or casual theft.
Delivers up to 10‑year standby on a single 24 000 mAh battery with once‑daily reporting, eliminating the need for frequent charging or battery changes. Deploy and track for a decade.
Switch to Emergency Mode for live tracking. Remotely awaken via SMS or command to provide real-time location updates for asset recovery.
Multi-constellation GNSS (GPS, GLONASS, BeiDou, Galileo) for precise positioning and 4G LTE Cat-1 with 2G fallback for worldwide coverage.
Integrated temperature sensor monitors environmental conditions from -20°C to +65°C with configurable high/low temperature alarms for cargo protection.
Built-in light sensor detects opening, 3-axis motion sensor monitors movement. Immediate notifications for unauthorized activity.
IPX7 waterproof rating, operates in extreme temperatures from -20°C to 60°C. Built for harsh environments.
GPT50's dual working modes adapt to your operational needs:
Default mode where the device wakes on schedule (e.g., once per day) to report location and returns to sleep. Power consumption is minimized – achieving multi-year battery lifespan. Still wakes instantly for critical events (motion or light) to send alarms.
When continuous updates are needed – for stolen or lost assets – remotely switch to Emergency mode via SMS, app, or server. Reports in real-time for a defined period, then automatically reverts to preserve battery life.

Eelink's GPT series includes both the GPT50 and the earlier GPT29 tracker. While they share some capabilities, they are optimized for different use cases. GPT29 is known as the "smartest in-transit monitoring device" with a rich sensor set for real-time shipment monitoring, whereas GPT50 is focused on ultra-long battery life for asset tracking.
| Feature | GPT50 – Long Standby Tracker | GPT29 – In-Transit Monitor |
|---|---|---|
| 🔋 Battery & Power | 24,000 mAh Li-MnO₂ (Primary cell, non-rechargeable) ✅ Provides up to 10‑year standby No recharging needed; replace device after battery is expended. |
4,200 mAh Li-Ion (Rechargeable) Provides weeks to months of operation on battery (depending on reporting rate) Can be recharged or powered by an external source for continuous use. |
| 📡 Reporting Frequency | Optimized for low-frequency reporting: ✅ Typically 1 report per day in normal use (configurable) Has a special Emergency Mode for temporary real-time tracking Best for assets where constant updates aren't needed until an event occurs. |
Optimized for real-time monitoring: Supports frequent updates (configurable 1 min to 24 hr reporting) Typically used to stream condition data continuously during shipments Ideal for live monitoring of shipments in motion. |
| 🔍 Sensors & Monitoring | Motion, Light & Temperature sensors for movement, tamper alerts and environmental monitoring ✅ Built-in Temperature Sensor (–20 ℃ ~ +65 ℃, high/low alarm) Focuses on security (detecting unauthorized movement or opening) and basic environmental monitoring. |
Comprehensive sensors: ✅ Motion, Light, Temperature, Humidity, Shock/Vibration sensors Monitors environmental conditions of cargo (e.g., cold chain monitoring) in addition to location. |
| 📶 Connectivity | LTE Cat-1 with 2G fallback ❌ No Bluetooth (to save power) ✅ Built-in Wi-Fi for location assist Designed for periodic upload of data. |
