A portable GPS tracker for work trucks is a battery-powered tracker you can drop into a truck, clip onto a trailer or tuck into a piece of equipment, with no wiring and no OBD-II port needed. Open the app and you see where it is, where it's been, and you get an alert the moment it moves when it shouldn't.
If you run a small service business, your trucks, trailers and gear don't live in a locked corporate yard. They sit at job sites overnight, in driveways and in parking lots. Below are the portable trackers worth considering for a 2 to 5 truck operation, how they compare on update speed, battery life and monthly fee, and the simple setup most small crews end up using.
The best portable GPS tracker for work trucks and equipment is ShadowTrack, paired with ShadowAuto in any truck that has an OBD-II port. ShadowTrack runs on its own battery for up to about 15 days and goes on trailers, mowers and generators with no wiring. ShadowAuto plugs into the truck and never needs charging. Both are cellular, both show on one map, and there's no contract.
What Is a Portable GPS Tracker?
A portable GPS tracker runs on its own rechargeable battery. It uses GPS satellites to find its position and a cellular connection to send that position to your phone. Because it doesn't draw power from anything, you can put it almost anywhere: a glovebox, a toolbox, under a trailer frame in a magnetic case, or inside an equipment housing.
Portable vs. plug-in OBD-II trackers: the real difference
A plug-in tracker goes into your truck's OBD-II port, the diagnostic port under the dash on every car and light truck sold in the US since 1996. It's powered by your truck, so you never charge it. A portable tracker works on anything, including assets with no port and no power, but it needs charging. For a mixed small fleet, the answer is usually both: plug-in in the trucks, portable on the trailers and equipment. See OBD2 vs. battery-powered GPS trackers for more.
Why Small Service Businesses Are Switching to Portable Trackers
Vehicle theft has dropped, but it hasn't gone away. The National Insurance Crime Bureau reports that 659,880 vehicles were stolen in the US in 2025, down 23% from 2024, which still works out to about one every 48 seconds (NICB). Equipment is harder to get back: in NICB and National Equipment Register reports, only about one in five stolen machines was recovered (20% of the equipment stolen in 2012, for example), and riding mowers have regularly ranked among the most-stolen items (Equipment World).
Mixed assets
Trucks, trailers, mowers and compressors. One type of tracker covers all of them, with no wiring into a $40,000 machine.
Moves with the work
Trailer parked at a job site for three weeks? The tracker stays with it. Sell a truck and the tracker moves to the next one.
More than theft
Trip history also answers "did the crew make it to the job?" and "how long were they there?"
Who Actually Needs a Portable GPS Tracker?
Landscaping crews
Trailers and mowers spread across properties every day. A tracker on each trailer plus a yard geofence covers what walks off overnight.
HVAC, plumbing and pest control
Vans that run all day carry expensive tools. Plug-in trackers in the vans, portable trackers on anything left at a job.
Contractors and Turo hosts
Generators and compact equipment at job sites, or rental cars rotating in and out of a small fleet.
The Best Portable GPS Trackers for Work Trucks and Equipment in 2026
We compared portable and plug-in trackers on what matters to a small crew: how often they report while moving, real battery life at that speed, how they mount on trucks and trailers, the monthly fee, and whether you're locked into a contract.
1. ShadowGPS ShadowTrack (and ShadowAuto for daily trucks)
ShadowTrack is the portable pick. It runs on its own rechargeable battery for up to about 15 days per charge, goes in a glovebox, a toolbox or a weatherproof magnetic case, and works on trailers, mowers, generators and older trucks with no port. While it's moving, it updates every 5 seconds, so you can follow a trailer being towed away in real time instead of watching a dot jump across town.
ShadowTrack
- No wiring and no port: drop it in or magnet-mount it in under 2 minutes
- Up to about 15 days per charge, moves between assets anytime
- Geofence and movement alerts when a trailer or machine leaves a site
For trucks and vans that run every day, pair it with ShadowAuto. You plug it into the OBD-II port in under two minutes, it's powered by your truck, and it never needs charging. It also reads engine codes, so you can see a check engine light on a crew truck from your phone. Both trackers show on the same map in one app.
ShadowAuto
- Plugs into the OBD-II port in under 2 minutes, powered by your truck
- Never needs charging, ideal for trucks that run every day
- Engine codes, Car Alarm and tamper alerts in the same app
To mount ShadowTrack on a trailer frame or steel equipment housing, add the weatherproof magnetic case. It keeps the tracker attached and protected from rain, road spray and dirt.
Magnetic Weatherproof Case
- Strong magnet for trailer frames and steel equipment
- Weatherproof housing for outdoor mounting
- Pops off in seconds when it's time to charge
Best for: small service businesses that want every truck, trailer and piece of equipment on one map, with fast updates and no contract.
2. LandAirSea 54
A long-running magnetic tracker brand that many trailer and equipment owners already know. It mounts with a built-in magnet and is designed to be tucked under a frame or bumper.
The catch is the plan structure. The base plan updates every few minutes, faster updates cost more, and the best monthly rate requires a 2-year commitment.
Pros
- Built-in magnet, no separate case needed
- Well-known brand with a long track record
- Low entry monthly price on long terms
Cons
- Base plan updates every 3 minutes
- Fastest updates sit on the most expensive tier
- Best rate requires a 2-year commitment
Best for: owners who mainly want an occasional location check on a trailer and are fine with slower updates.
3. BrickHouse Security Spark Nano 7
A small cellular tracker with optional extended-battery magnetic cases, common with businesses that track personnel and equipment.
Plans are tiered by update speed, so the cost climbs if you want near real-time tracking across several trucks.
Pros
- Compact and easy to hide in a glovebox or toolbox
- Extended-battery magnetic case available
- Established security brand
Cons
- Tiered plans, roughly $18 to $35 a month
- Faster updates cost more
- Costs add up across a multi-truck fleet
Best for: businesses that already use BrickHouse for other security needs and want one vendor.
4. Tracki
A small, inexpensive universal tracker that works for vehicles, luggage and gear, with international coverage.
Battery life drops sharply at fast update settings, and the lowest monthly rates require a 2-year plan.
Pros
- Low device price
- Works on almost anything, worldwide coverage
- Small enough for a toolbox or bag
Cons
- Battery can drop to 2 to 5 days at fast update settings
- Fastest updates need a higher tier
- Billing and cancellation complaints are common
Best for: tracking one or two small items on a tight budget where real-time speed isn't critical.
5. Invoxia GPS Tracker
Invoxia focuses on battery life, advertising up to a month on its GPS Tracker Pro, with anti-theft alerts and a compact design.
Long battery life comes from less frequent location reporting, so it's better for assets that sit than for following a truck live.
Pros
- Long battery life between charges
- Compact and easy to hide
- Anti-theft movement alerts
Cons
- Less frequent updates than a real-time tracker
- Not built for live following of a moving truck
- Subscription required
Best for: equipment that sits for weeks at a time where you mainly need a move alert.
6. SPOT Trace
SPOT Trace uses satellites instead of cell towers, so it reports from remote job sites, ranches and rural roads with no cell signal.
Updates come every few minutes, not seconds, and it's a different kind of tool than a cellular real-time tracker.
Pros
- Works where there's no cell coverage
- Satellite-based, good for remote sites
- Movement alerts
Cons
- Updates in minutes, not seconds
- Bulkier than cellular trackers
- Separate satellite service plan
Best for: equipment parked at remote sites with no cell signal.
7. Apple AirTag & Tile
Bluetooth tags are great for finding keys and tool bags, but they aren't GPS trackers. They only update when someone else's phone passes nearby, which makes them unreliable for a stolen trailer on a rural road.
Turo also prohibits AirTags as an active tracking device for rental cars.
Pros
- Very low cost, no monthly fee
- Long coin-battery life
- Good for tool bags and keys
Cons
- No cellular, no real-time tracking
- Depends on nearby phones
- Anti-stalking alerts can tip off a thief
Best for: small tools and keys, alongside a real GPS tracker on the truck or trailer.

Key Features That Actually Matter in a Portable GPS Tracker
Cellular, not Bluetooth
A cellular tracker reports on its own from anywhere with coverage. With ShadowGPS the cellular connection is built in, so there's no SIM card to buy (more on SIM cards).
Update speed you can actually use
Check how often it reports while moving, and whether faster updates cost extra. A tracker that checks in every few minutes tells you where a trailer was, not where it is.
Battery life at that speed
Every portable tracker trades update speed against battery. Months of battery usually means infrequent check-ins. Ask for battery life at the update rate you'll really use, and plan a charging routine: most crews pull their trackers every other week and charge them overnight. The app shows each tracker's battery level, so nothing goes dark by surprise. See how long GPS tracker batteries last.
Weatherproof magnetic mounting
For trailers and equipment, a weatherproof magnetic case is close to essential. Keep the tracker out of fully enclosed steel boxes, which can weaken the signal.
Geofences and movement alerts
Draw a boundary around your yard and job sites and you hear about it when something leaves, not the next morning. Here's how to set up geofence alerts that catch overnight theft.
Every asset in one app, and no contract
Trucks, trailers and equipment should all show on one map under one login on the app and the web. And for a 3-truck operation, avoid multi-year lock-ins.
Is it legal to put a GPS tracker on work trucks and equipment?
Yes, on vehicles and equipment your business owns. If employees drive tracked trucks, tell them in writing first: Connecticut, Delaware, New York and Maine have electronic-monitoring notice laws, and California has stricter consent rules. Never put a tracker on an employee's personal vehicle without written consent. Turo hosts should note that Turo allows GPS trackers, prohibits AirTags as active trackers, and requires disclosure in some locations (Turo policy). Read more in is GPS tracking legal for employee vehicles. This isn't legal advice.
Choosing the Right Tracker for Your Trucks and Equipment
- Trucks and vans that run every day: ShadowAuto in the OBD-II port. No charging, ever. More in GPS trackers for work vans.
- Trailers: ShadowTrack in a weatherproof magnetic case on the frame, plus a yard geofence.
- Mowers, generators and compact equipment: ShadowTrack with a job-site geofence. See GPS trackers for landscaping.
- Remote sites with no cell signal: a satellite tracker like SPOT Trace.
- Heavy machinery fleets: see our construction equipment tracking guide.
What does it cost to track a 5-truck business?
Five trackers at $69.90 each is $349.50. On the 4 to 10 tracker plans, a year of service runs $780 month-to-month ($13/mo each), $600 on the annual plan ($10/mo each), or $480 for the first year of a 2-year prepay ($8/mo each). That puts year one between about $830 and $1,130. No contract. Month-to-month, or prepay and save. Full breakdown: how much GPS tracking costs for a small fleet.
Frequently Asked Questions
Is there a monthly fee for a portable GPS tracker?
Yes. Real-time tracking runs on cellular data, so there's a monthly fee. ShadowGPS plans run $15/mo month-to-month down to $9/mo on a 2-year prepay for 1 to 3 trackers, and $13 to $8/mo per tracker for 4 to 10. No contract. Month-to-month, or prepay and save. See current pricing.
Does a portable GPS tracker need a SIM card?
Not one you buy. The cellular connection is built into ShadowGPS trackers and included in the plan.
How long does a portable GPS tracker battery last?
ShadowTrack lasts up to about 15 days per charge, depending on how much the asset moves. Trackers that advertise months of battery usually update much less often.
Should I use a portable or plug-in tracker on a work truck?
If the truck has an OBD-II port and runs daily, a plug-in tracker like ShadowAuto is simpler because it never needs charging. Choose a portable tracker for trucks without a usable port or when you want to move it between vehicles.
Will a portable tracker work on a trailer with no power?
Yes. ShadowTrack runs on its own battery, so it doesn't need the trailer's wiring. Mount it in a weatherproof magnetic case on the frame.
Can I track all my trucks and equipment in one app?
Yes. ShadowAuto and ShadowTrack trackers all show on one map in the same account, on your phone and on the web.
Does Turo allow portable GPS trackers?
Turo allows GPS trackers, prohibits AirTags as active trackers, and requires hosts in some locations to disclose tracking to guests. Our Turo page has setup tips.
What happens if I cancel?
There's no contract, so you can cancel any time. Tracking stops at the end of your paid period, and you keep the device.
Plug it in. See it move. Cancel any time.
ShadowTrack for your trailers and equipment, ShadowAuto for your trucks. Every asset on one map. No contract, ever.
