Trailer Tracking Device: Solar, Battery or Hardwired?

Key takeaways

What's the best GPS tracker for a trailer?

There isn't one answer for every trailer. Three questions narrow it down quickly:

A trailer that sits for weeks needs a tracker that lasts without charging and tells you when it moves. A trailer that is on the road every day, or has its own battery, can take a hardwired unit that reports often.

Solar vs battery vs hardwired

Hardwired

A hardwired tracker runs off a battery on the trailer, so it can report often without ever being recharged. The tow vehicle's plug only supplies power while the trailer is hooked up, so for tracking while parked it needs a battery on the trailer itself. Installation takes more work, and a power-disconnect alert tells you if someone cuts it.

Battery-powered

A self-contained unit with its own battery. It is quick to install and easy to hide almost anywhere. Battery life depends on how often it reports, so it suits trailers that sit for long periods and don't need minute-by-minute updates.

Solar

A battery tracker with a small solar panel that tops it up. It has to be mounted where sunlight reaches it, which can also make it easier to spot. It suits trailers stored outdoors that you rarely check. In shaded storage or long cloudy spells it runs on its battery like any other unit.

How often should a trailer tracker report?

Reporting frequency is the trade-off between battery life and how fast you see a move. A tracker that checks in once a day can last a long time on one battery, but a thief could have the trailer hours away before you know. Some battery trackers report more often once they sense movement, which helps close that gap.

Hardwired units can report on a short schedule all the time. The GPS Leaders rugged tracker, built for trailers as well as machines, updates every 10 minutes and sends alerts as they happen.

When you compare battery life, ask for the figure at the reporting schedule you actually plan to use, not the best-case number.

Where to hide a trailer tracker

What to do if your trailer is stolen

Recovery is far from certain. About 63% of stolen RVs remain unrecovered (NICB, 2025 data). For commercial trailers, cargo theft losses reached an estimated $725 million in 2025, up 60% (Verisk CargoNet, 2025 Supply Chain Risk Trends). A tracker shortens the time between the theft and the call to police, which is where it helps most.

Trailer tracker vs AirTag

AirTags are cheap and easy to hide, and plenty of owners use them. They find their location through nearby Apple devices, so they work best where people are around and can be slow to update on rural roads or in quiet storage lots. iPhones also warn people when an unknown AirTag is traveling with them, which can tip off a thief.

A cellular GPS tracker reports on its own schedule from anywhere with coverage, and can alert you the moment the trailer leaves a set area or loses power.

FAQ

Do solar GPS trackers work on trailers?

Yes, if the panel gets regular sunlight. The panel tops up the battery so it lasts longer between charges. In shade or long cloudy stretches the tracker runs on its battery alone.

How long does a trailer tracker battery last?

It depends mostly on how often the tracker reports. Fewer check-ins mean longer battery life and slower alerts. Ask for the battery life at the schedule you plan to use.

Can I power a tracker from the trailer's plug?

Only while the trailer is hooked to the tow vehicle. To track it while it is parked, you need a battery on the trailer or a battery-powered tracker.

Will a tracker stop my trailer from being stolen?

No. It tells you when the trailer moves and where it is. Pair it with a coupler lock or wheel lock to make the trailer harder to take in the first place.

Can I track a trailer in Canada or Mexico?

The GPS Leaders tracker uses 4G LTE coverage in the U.S., Canada and Mexico.
