10 Trailer and Container Trackers, Compared on Battery and Where They Stop Working

Trailers are where tracking rollouts stall. Vehicles get done first because they supply power and a fitter can wire a device in an afternoon. Then the project reaches the trailers, the containers and the yard equipment, discovers none of them have a battery to draw on, and quietly stops. That matters because the asset tracking market keeps growing around exactly this gap.

Two physical facts rule the category. A trailer gives you no power, so every position fix spends a finite budget. And a steel container blocks the sky, so a device sealed inside it cannot see a satellite at all. Everything below is organised around those two constraints, with every figure taken from the vendor’s own page on 18 September 2026.

The result is that the fast, feature-rich devices that suit a delivery van are the wrong answer here, and the devices that are right look underpowered on a spec sheet until you read the battery line properly.

What Goes Wrong on Trailers Specifically

Four failures account for most of it, and none of them is a software problem.

The first is mounting inside a steel box. A tracker sealed in a container with the cargo cannot see the sky and stops producing fixes, which reads in the app exactly like a dead device. The fix is to mount on the outer skin or the roof.

The second is configuring a real-time interval on an unpowered asset. A trailer set to report every thirty seconds will need charging every fortnight, and nobody schedules that, so the fleet quietly goes dark one unit at a time.

The third is theft removal. A magnetic tracker in the obvious spot under the coupling is the first thing a competent thief checks. This is why concealed second devices exist.

The fourth is temperature. Trailers sit outside all year, and a device rated to minus 20 Celsius in a yard that hits minus 30 is out of specification exactly when you need it.

Where the Multi-Year Devices Earn Their Place

GPX states up to ten years at one report per day for the AssetTrack, from an IP67 unit rated minus 30 to 80 Celsius with an internal magnet and an anti-tamper sensor. It also carries a Bluetooth radio that reads nearby tags, so one cellular device on the trailer can act as the reader for the things riding inside it.

Verizon Connect quotes the longest figure in the group at up to thirteen years for the battery EAT-B, footnoted as assuming optimal conditions, which is a caveat doing real work. Logistimatics publishes the cheapest route to the same idea at $54.99 with up to five years, IP67, rated to minus 30, and a field-replaceable cell rather than a sealed one.

All three share the same logic: report once a day, drop to a fix every five minutes only during a recovery, and never ask anyone to charge anything.

Where the Short-Life Devices Still Win

A recovery is not a monitoring job. When a trailer is actually stolen you want a position every few seconds, and the devices built for that are the ones with weeks of battery rather than years. LandAirSea at $29.95 with a published three-second tier, or Tracki Pro at $28.99 with a 10,000 mAh cell, are both sensible as the concealed second unit on a high-value asset.

Spytec Atlas XL sits between the two extremes: up to 365 days at one fix a day, falling to 48 days at an hour of daily movement on minute updates. For a trailer that moves most weeks, that is a realistic charging cycle.

The One-Way Case Nobody Budgets For

Some loads never come back, and putting a durable tracker on them means buying a device you will not see again. That is what disposable shipment labels exist for. GPX’s SmartLabel is a peel-and-stick Bluetooth label 0.4mm thick at its thinnest, rated up to 60 days on a non-replaceable cell, with tracking included for the life of the battery and no subscription per device.

It has no GPS and no SIM, so accuracy is quoted at typically 20 to 100 feet and coverage follows gateway density rather than satellites. For a one-way freight lane that is the right trade. For a trailer that returns every week it is the wrong product entirely.

Split the Fleet Before You Buy Anything

Sort what you own into three groups: assets that return and are worth a multi-year device, high-value assets that justify a second concealed real-time unit, and one-way loads that need something disposable. Those three groups have almost no product overlap, and buying one device for all three is the most common way a trailer programme ends up costing more than it saves.

Once the groups are drawn, the battery figure and its duty cycle do most of the shortlisting for you. Our guide to how shipping containers stay visible covers the signal problem in depth, and seven asset tracking companies for equipment with no engine compares the vendors behind these devices.
