Queclink GV620MG — Ruggedised LTE Cat M1 Rechargeable Trailer Tracker with 120-Day Battery

The Queclink GV620MG is purpose-built for one of the most demanding challenges in fleet telematics — keeping heavy duty trailers, tankers, refrigerated units and flatbed trucks visible and monitored at all times, even when disconnected from the tractor unit for days, weeks or months. Its massive 5,800mAh internal Li-ion battery pack provides up to 120 days of standby time, ensuring continuous location reporting throughout the full disconnected period without any manual attention or recharging.

Built into a ruggedised IP67 waterproof enclosure with internal antennas and designed specifically for the harsh environments of fuel, chemical and refrigerated transportation, the GV620MG delivers reliable performance where standard trackers fail. Global LTE Cat M1 and NB2 connectivity via Queclink's unique antenna solution ensures broad network coverage across the UK and internationally, with automatic 2G fallback for complete reliability. A wide range of pre-integrated wired and wireless accessories — including BLE temperature and humidity sensors, BLE key fobs, BLE padlocks and RS232 refrigeration controller integration — extends the GV620MG's monitoring capability across virtually any heavy duty fleet application.

As an authorised Queclink distributor in the UK, Tracking Hardware UK ships the GV620MG directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.

Frequently Asked Questions

How long does the GV620MG battery last without external power?

The GV620MG's 5,800mAh dual Li-ion battery pack provides up to 120 days of standby time — four months of continuous tracking without any external power connection or manual recharging. Actual standby time depends on reporting frequency, network conditions, BLE activity and temperature.

Does the GV620MG support refrigerated trailer monitoring?

Yes — the GV620MG supports refrigerated trailer monitoring through multiple interfaces. BLE 5.0 connects to wireless temperature and humidity sensors for cold chain compliance. The RS232 port connects directly to refrigeration controller units for operational data. The 1-Wire interface supports additional temperature probes. Together these provide comprehensive cold chain monitoring from a single device.

What is the BLE padlock support?

The GV620MG supports pre-integrated BLE padlocks — connected via BLE 5.0, the padlock status can be monitored and in some configurations remotely controlled via the fleet management platform, providing an additional layer of cargo security monitoring for trailer operators.

Does the GV620MG support dual external power sources?

Yes — the GV620MG supports connection to two independent external power sources simultaneously. When external power is available from the tractor unit or trailer electrical system, the internal battery is recharged. When disconnected, the device automatically runs on its internal battery for up to 120 days.
