Wired vs Magnetic GPS Tracker: Which Is Better for Cars and Fleets?

A wired vs magnetic GPS tracker comparison is one of the first things to consider when choosing a vehicle tracking device. Both types can send vehicle location data to a tracking platform, but they differ in installation, power source, and ideal use case.

For permanent vehicle and fleet tracking, a wired tracker is usually the better choice. In contrast, a magnetic tracker can be more practical for containers, cargo, temporary tracking, or situations where vehicle wiring is not possible.

What Is a Wired GPS Tracker?

A wired GPS tracker connects to the vehicle's electrical system. Therefore, it does not require regular charging during normal use.

Depending on the model, wired trackers may also support features such as ACC detection, relay outputs, SOS buttons, or external sensor inputs.

They are commonly suitable for:

• company vehicles
• corporate fleets
• taxis and service vehicles
• trucks and heavy vehicles

For example, the Exir ME300 is designed for enterprise vehicles and fleet applications. It supports 2G/4G connectivity, battery backup, SOS, sensor inputs, and relay output.

What Is a Magnetic GPS Tracker?

A magnetic GPS tracker normally operates using an internal battery. As a result, it does not need to be permanently connected to vehicle wiring.

This also makes the device easier to move between assets.

Magnetic trackers can be useful for:

• containers
• cargo
• temporary tracking
• assets where permanent wiring is not practical

For example, the Exir AT01 is a magnetic 4G/LTE tracker with an internal battery and IP67 protection. It is designed for wire-free tracking applications.

Wired vs Magnetic GPS Tracker: What Is the Difference?

When comparing a wired vs magnetic GPS tracker, the main differences are power, installation, and intended use.

Therefore, neither type is automatically better for every situation.

Is GPS Accuracy Different?

Being wired or magnetic does not by itself determine GPS accuracy.

Receiver quality, antenna design, installation location, and satellite signal conditions also affect positioning performance. Therefore, when comparing a wired vs magnetic GPS tracker, the power source should not be treated as the main indicator of GPS accuracy.

Which Tracker Is Better for a Fleet?

For vehicles that operate permanently within a company fleet, a wired GPS tracker is generally the more practical option.

Continuous vehicle power and, depending on the model, access to inputs and outputs make wired devices particularly useful alongside fleet management software.

However, if permanent wiring is not possible or the goal is tracking containers or cargo, a magnetic tracker may be more suitable.

Does a Magnetic GPS Tracker Need Charging?

Yes. A magnetic tracker depends on its internal battery, so it eventually needs to be recharged.

Battery life varies according to the device, battery capacity, transmission frequency, and configuration.

The current AT01 specifications state more than 30 days of continuous battery use.

Wired vs Magnetic GPS Tracker: Which Should You Choose?

Choose a wired tracker first if you need permanent tracking for company vehicles or a fleet.

On the other hand, consider a magnetic model if you need wire-free installation, easy relocation, or tracking for containers and cargo.

Ultimately, choosing a wired vs magnetic GPS tracker should depend on the vehicle, installation conditions, required operating time, and management requirements.
