Best Electronic Logs For Trucks: Compare 10 ELD Options

#1 · Best Overall

1. Garmin eLog

Best for: No-subscription semi-truck logging.

Why it ranks #1: FMCSA-compliant HOS recording, no subscription fees, and support for both 9-pin J1939 and 6-pin J1708 ports make it a clear fit for many trucks.

Automatic HOS recording without subscription fees is the Garmin eLog’s clearest distinction, enabling a stand-alone route to FMCSA ELD compliance. It supports 9-pin J1939 and 6-pin J1708 diagnostic ports, and stores records on a compatible smartphone for access during an inspection.

The one-time-purchase, stand-alone device automatically records Hours of Service, so drivers can use its compliance workflow without a recurring subscription. Its 9-pin J1939 and 6-pin J1708 support covers those diagnostic connections, while records stored on a compatible smartphone can be accessed for inspection through the device’s USB port or FMCSA Web Services. Check the port before choosing it: OBD-II vehicles are unsupported, and Volvo vehicles with 16-pin J1962 need a separate cable that is not included.

Skip it if you have an OBD-II truck; Konexial My20 lists OBD-II support through an available adapter.

A fit for drivers seeking stand-alone HOS recording without subscription fees, especially with a supported J1939 or J1708 port. Verify the truck’s connection first; OBD-II vehicles are excluded, and some Volvo installations need a separate cable.

#2 · Best Fleet Features

2. Konexial My20 ELD

Best for: Bluetooth smartphone logging.

Why it ranks #2: Pairs with iPhone, iPad, and Android devices over Bluetooth and lists GPS tracking, log auditing, DVIR, messaging, and reporting; subscription is required.

Bluetooth links the My20 ELD to an iPhone, iPad, Android phone, or Android tablet, enabling an app-based workflow for truck logs. Its standard 9-pin J1939 connector serves compatible diagnostic ports, while the listed support for GPS tracking, DVIR, and digital documentation extends the device beyond HOS recording.

Install the device in the diagnostic port, download the My20 app, and link a mobile device over Bluetooth; that sequence keeps logging and related tools on a phone or tablet. The 9-pin J1939 connector is standard, and adapters are available for OBD-II or 6-pin ECM ports, giving some trucks another connection route. GPS tracking, log auditing, DVIR, fuel information, messaging, reports, and maps support additional fleet tasks. Registration terms and a current subscription are required for service.

Skip it if you want a no-subscription ELD; Garmin eLog records HOS without subscription fees, though its port support differs.

For drivers and fleets wanting mobile logs plus GPS, DVIR, and documentation tools, the My20 combines those functions in an app-linked workflow. Account for its subscription requirement and check which diagnostic port or adapter your truck needs.

#3 · Built-In 9-Pin

3. IOSiX IO-1020 Micro ELD

Best for: Integrated 9-pin HOS connection.

Why it ranks #3: Its built-in 9-pin green connector needs no cable, while Bluetooth, Wi-Fi, and GNSS are listed; a compatible HOS app is still needed.

A built-in green 9-pin connector removes the need for a separate cable, enabling a direct connection on compatible trucks. The IOSiX IO-1020 combines Bluetooth 4.2 with WiFi and a multi-constellation GNSS receiver, supporting wireless communication and satellite-based location capabilities in a compact Micro ELD.

With its built-in 9-pin connector, the IO-1020 avoids a separate cable for trucks using that port, simplifying the physical connection. Bluetooth 4.2 supports communication with an HOS app, while WiFi offers simultaneous access-point and station modes. Its multi-constellation GNSS receiver and high-gain antenna support location data, and the full-color RGB LED provides status indication. Over-, under-, and reverse-voltage protection and ESD protection address electrical conditions; the listed connector remains the key compatibility check.

Skip it if you need an OBD-II cable for a light-duty pickup; the IOSiX-based B0GTS11V45 bundle lists one.

A fit for drivers using a compatible 9-pin connection who want an integrated connector, Bluetooth, WiFi, and GNSS in a Micro ELD. Its built-in port makes it less suitable when the truck requires a different cable.

#4 · Broad Port Support

4. TEMEDA PT30 ELD

Best for: Multi-port PT30 flexibility.

Why it ranks #4: The PT30 package lists J1939, J1708/J1587, and OBD-II connections, Bluetooth Low Energy, and compatibility with ELD/HOS apps.

Support for J1939, J1708/J1587, and OBD-II connections gives this PT30 a broad stated port range, enabling engine-data access across compatible truck setups. Bluetooth Low Energy links it to a phone or tablet, while large-capacity offline storage supports operations when a cellular connection is unavailable.

The listed diagnostic connections—J1939, J1708/J1587, and OBD-II—let the PT30 read engine diagnostics directly from a compatible vehicle. Bluetooth communication works with compatible ELD/HOS apps on a phone or tablet, keeping the logging interface on a device the driver already uses. Large-capacity storage is specified for offline operations, while the ability to plug in or unplug as needed supports portable compliance workflows. The package includes one PT30 and one cable; app compatibility remains part of the setup.

Skip it if you want a listed no-subscription stand-alone logger; Garmin eLog records HOS as a stand-alone device without subscription fees.

For operators needing several listed diagnostic connection types, offline storage, and app-based logging, this PT30 offers a flexible connection set. Its workflow requires a compatible ELD/HOS app, so verify the app and cable arrangement for your vehicle.

#5

5. PT30 OBD-II ELD

Best for: 16-pin fleet logging.

Why it ranks #5: Includes an OBD-II 16-pin medium/light-duty cable and is described for HOS logging and GPS fleet tracking, making it a targeted option for matching vehicles.

The included 16-pin medium/light-duty OBD-II cable gives this PT30 package a defined connection focus, enabling HOS logging for compatible commercial vehicles. Its description also identifies GPS fleet tracking, making it relevant to owner-operators and fleet managers looking to pair driver logs with vehicle-location capabilities.

The PT30 is described as an electronic HOS logbook for commercial trucks and fleets, supporting electronic driver logs and duty-status management. The included medium/light-duty 16-pin OBD-II cable gives the package a specific diagnostic connection rather than an unspecified connector choice. GPS-based fleet tracking can also serve fleet operators monitoring vehicle location. Since the supplied details do not name compatible apps or further port configurations, buyers should treat the stated cable and intended vehicle class as the key fit information.

Skip it if you need a listed 9-pin connection; the PT30 package from B0HH8YKVTF is specified with a 9-pin cable.

Consider this PT30 bundle if your commercial vehicle uses the included medium/light-duty 16-pin OBD-II cable and you want HOS logging with GPS fleet tracking. The supplied information does not identify app compatibility or additional cable options.

#6

6. PT30 16-Pin ELD

Best for: Heavy-duty 16-pin applications.

Why it ranks #6: Includes a heavy-duty 16-pin cable intended for compatible Volvo and Mack trucks; the listing advises checking the connector configuration before ordering.

The included heavy-duty 16-pin diagnostic cable makes this PT30 package specifically relevant to compatible Volvo and Mack trucks, enabling connection through the vehicle’s diagnostic port. The package combines that cable with the PT30 ELD for electronic logging and vehicle-data communication, with installation described as a straightforward connection.

The PT30 and included heavy-duty 16-pin cable form a complete package for vehicles using that connector, with the description naming compatible Volvo and Mack trucks. Connecting the cable to the truck’s diagnostic port supports electronic logging and vehicle-data communication. The listing advises checking the truck’s configuration because connector arrangements can vary by model and year; that makes the 16-pin requirement central to fit. Its stated purpose is a commercial-truck ELD, not a universal cable bundle.

Skip it if you use a 9-pin port; the PT30 bundle from B0HH8YKVTF is supplied with a 9-pin cable.

A fit for Volvo or Mack operators whose vehicle uses the specified heavy-duty 16-pin connection and who need PT30 electronic logging. Check the diagnostic configuration carefully, since the listing limits this package to 16-pin applications.

#7

7. PT30 9-Pin ELD

Best for: 9-pin commercial vehicle connection.

Why it ranks #7: Supplies a 9-pin cable and Bluetooth connectivity for compatible devices and ELD applications, but the listing provides fewer detailed app or compliance specifics.

A supplied 9-pin cable is the defining feature of this PT30 ELD package, enabling a direct connection in compatible commercial vehicles. Bluetooth communication with compatible mobile devices and ELD applications supports a phone-linked workflow, while engine-data access and vehicle-location tracking add fleet monitoring functions.

The included PT30 device and 9-pin cable connect the unit to a compatible vehicle, with the listing describing installation as straightforward. Bluetooth links it to compatible mobile devices and ELD applications, so the workflow depends on supported software rather than a stated stand-alone display. The engine-data connection supplies vehicle information to that software, while real-time location tracking can help fleet owners monitor vehicles. Confirm that the vehicle uses the specified 9-pin connection and compatible ELD system.

Skip it if you need a 16-pin heavy-duty cable; the PT30 package from B0HK3QHQ7J includes that cable for compatible vehicles.

A potential fit for commercial-vehicle operators whose trucks use the included 9-pin cable and whose ELD application supports Bluetooth communication. Its workflow relies on compatible software, so check both the vehicle connection and app before selecting it.

#8

8. PT30 Volvo Cable Bundle

Best for: Weatherproof Volvo ELD bundle.

Why it ranks #8: The PT30 bundle includes a heavy-duty OBDII cable specifically described for Volvo trucks, so its usefulness depends on that vehicle fit.

Weatherproof construction and a heavy-duty OBDII cable for Volvo trucks define this PT30 bundle, enabling a connection-focused ELD setup for that vehicle application. The product details identify a 12-volt maximum and recommend it for connecting and operating ELD devices in Volvo heavy-duty trucks.

The PT30 bundle is described as including a heavy-duty OBDII cable for Volvo trucks, giving buyers a specific vehicle and connection focus. Its weatherproof feature can matter where the device is exposed to operating conditions, while the listed 12-volt maximum supplies an electrical specification for installation planning. The recommended use is connecting and operating ELD devices in Volvo heavy-duty trucks. The listing names no compatible phone models, so it does not establish a phone-based interface or app workflow.

Skip it if you need a specified compatible phone; Konexial My20 lists iPhone, iPad, Android phone, and Android tablet support.

Consider this bundle for Volvo heavy-duty truck operators seeking a weatherproof PT30 setup with a heavy-duty OBDII cable. Its listed phone compatibility is unspecified, so it is a better fit when the cable and vehicle application are the priority.

#9

9. TFM ELD

Best for: Basic FMCSA-compliant ELD.

Why it ranks #9: The listing identifies it as an FMCSA-compliant truck ELD and gives a one-year manufacturer warranty, but provides no connector or app details.

FMCSA compliance is the concrete claim attached to this TFM ELD listing, identifying it for truck operators seeking an electronic logging device. The supplied product information is brief, naming the ELD and a one-year manufacturer warranty but providing no connector, app, or workflow specifications to guide a more detailed fit assessment.

The title identifies this product as an electronic logging device for trucks and states FMCSA compliance, which makes compliance its only clearly specified operating purpose. TFM ELD is the named brand, and the specifications list a one-year manufacturer warranty. No diagnostic connector, mobile-device support, connectivity method, or additional logging tools are described in the supplied information, so buyers cannot use this listing to establish those details. Treat the stated compliance claim as the scope of the available product facts.

Skip it if you need a stated diagnostic port; Garmin eLog lists support for 9-pin J1939 and 6-pin J1708 connections.

This may suit a buyer focused on the listing’s FMCSA-compliant ELD designation and willing to seek more product details before choosing. The supplied facts do not establish its port, connectivity, app support, or logging workflow.

#10

10. IOSiX Pickup ELD

Best for: Pickup truck OBD-II logging.

Why it ranks #10: Its IOSiX-based device lists a built-in 9-pin connector and a light-duty OBDII square cable, but the pickup-specific listing is less directly suited to truck fleets.

The light-duty OBDII square cable distinguishes this pickup-truck ELD bundle, enabling a connection aimed at compatible light-duty vehicles. Its IOSiX IO-1020 device features Bluetooth 4.2, WiFi, and a multi-constellation GNSS receiver with a high-gain antenna, supporting wireless communication and location functions.

The included light-duty OBDII square cable gives this bundle a stated pickup-truck connection focus, while the IO-1020’s Bluetooth 4.2 supports communication with compatible devices. WiFi operates in simultaneous access-point and station modes, and the multi-constellation GNSS receiver with high-gain antenna supports location acquisition. Over-, under-, and reverse-voltage protection and ESD protection address electrical conditions. The supplied details identify a tablet as a compatible device but do not name a broader phone list.

Skip it if you need a built-in 9-pin connection without a cable; the IOSiX IO-1020 from B0CKCJHZYD has one.

This bundle suits pickup operators whose vehicle uses the listed light-duty OBDII square connection and who want Bluetooth, WiFi, and GNSS features. Its cable focus is light-duty, so it is not the specified choice for a heavy-duty port.
