Best Electronic Logs For Trucks: Compare 10 ELD Devices

#1 · Best Overall

1. Garmin eLog

• Warranty Description: 1 year limited warranty

Best for: No-subscription semi-truck logging.

Why it ranks #1: FMCSA-registered HOS logging, no subscription fees, and stated 9-pin J1939 and 6-pin J1708 support suit many semi-trucks.

Support for both 9-pin J1939 and 6-pin J1708 ports is the Garmin eLog’s defining advantage, letting compatible semi-trucks record Hours of Service without an additional subscription. Its stand-alone setup stores ELD records on a compatible smartphone, with inspection access through the device’s USB port or the FMCSA web service.

The 9-pin J1939 and 6-pin J1708 support covers two common diagnostic-port types, and the included 6-pin adapter helps with a J1708 installation. Automatic HOS recording and secure smartphone storage put logs within reach during an inspection, while USB-port and FMCSA web-service access offer additional ways to retrieve records. The one-time-purchase model avoids subscription fees. Check the port before buying: it does not support OBD-II vehicles, and Volvo 16-pin J1962 trucks need a separate cable.

Skip it if you drive an OBD-II truck; the Garmin does not support that protocol, so choose a device listing OBD-II compatibility.

A good fit for drivers seeking straightforward HOS logging on a compatible J1939 or J1708 semi-truck without subscription fees. Verify the diagnostic port first; OBD-II trucks are excluded, and Volvo 16-pin J1962 requires an additional cable.

#2 · Broad Protocol Support

2. ELD Mandate IOSiX

• Warranty Description: 1

Best for: Cable-free 9-pin installation.

Why it ranks #2: Lists J1939, J1708/J1587, and OBD-II compatibility, plus a built-in 9-pin form factor and connector for other port types.

A built-in 9-pin form factor lets the IOSIX ELD connect without a cable on standard 9-pin installations, simplifying the physical setup. For other vehicle ports, the listing says a connector is included and names J1939, J1708/J1587, and OBD-II protocol compatibility, broadening its stated vehicle coverage.

The integrated 9-pin connection avoids a separate cable on standard 9-pin vehicles, while an included connector accommodates other listed port types. Compatibility with J1939, J1708/J1587, and OBD-II protocols gives drivers multiple connection options. The built-in 3-axis accelerometer analyzes driving behavior, adding a safety-oriented data function alongside HOS compliance. Smartphone and tablet compatibility supports a mobile workflow, and real-time tracking is listed as a special feature. Confirm the included connector matches your particular vehicle port before installation.

Skip it if you need a named compatible app before choosing; TEMEDA PT 30 states it works with compatible ELD/HOS apps and Bluetooth devices.

A practical candidate for truckers seeking a cable-free standard 9-pin installation with other protocol options and driving-behavior analysis. Check connector fit and app requirements for your vehicle and mobile workflow before putting it into service.

#3 · Multi-Port PT30

3. TEMEDA PT 30

• Warranty Description: 1 year

Best for: Multi-port app-connected logging.

Why it ranks #3: Includes a cable and lists J1939, J1708/J1587, and OBD-II connections, with Bluetooth communication to compatible apps.

J1939, J1708/J1587, and OBD-II connections give the TEMEDA PT 30 a broad port range, while Bluetooth Low Energy links it to a phone or tablet. That combination suits drivers who want to use a compatible ELD/HOS app and read engine diagnostics without relying on a single connection type.

The included cable and listed J1939, J1708/J1587, and OBD-II connections give buyers options across several vehicle port types. Bluetooth Low Energy communicates with a phone or tablet, and compatibility with ELD/HOS apps lets the driver use a compatible app for logging. Large-capacity storage supports offline operations, useful when an active connection is unavailable. Integrated engine diagnostics and an antenna add vehicle-data capability; the listing does not name a specific app, so app choice remains part of setup.

Skip it if you want records stored on a compatible smartphone with USB and FMCSA web access; Garmin eLog lists those retrieval options.

Consider this PT 30 bundle if you need several listed port protocols, Bluetooth app connectivity, and offline storage. It fits a phone-or-tablet workflow; choose a compatible ELD/HOS app, since none is identified by name in the supplied details.

#4 · Fleet Tools

4. Konexial My20 ELD

Best for: Fleet telematics and log auditing.

Why it ranks #4: Pairs an ELD with GPS tracking, log auditing, DVIR, documentation, reports, and messaging; its service requires a current subscription.

Log auditing and GPS tracking make the Konexial My20 more than a basic logging connection, giving drivers and fleets additional tools through its smartphone app. The device connects by Bluetooth after installation in the diagnostic port, and its listed features include DVIR, digital documentation, reports, maps, messaging, and fuel information.

A standard 9-pin J1939 ECM connector supports a direct diagnostic-port installation, while Bluetooth links the device with the My20 app on an iPhone, iPad, or Android phone or tablet. GPS tracking, log auditing, and reports support fleet oversight; DVIR and digital documentation add recordkeeping tools. The app also lists maps, messaging, and fuel information. OBD-II and 6-pin ECM adapters are available for purchase, and service requires an active subscription, so account terms are part of the ongoing setup.

Skip it if you want a one-time purchase without subscription fees; Garmin eLog lists no subscription fees for its logging device.

A fit for fleets or drivers who want GPS tracking, log auditing, and app-based documentation alongside ELD service. It uses a subscription, and trucks with OBD-II or 6-pin ports need separately purchased adapters.

Why it ranks #5: The listing describes an IOSiX Micro ELD with a built-in 9-pin connector, Bluetooth, Wi-Fi, and a multi-constellation GNSS receiver.

A built-in green 9-pin connector means this International truck HOS device needs no separate cable for that connection. Its multi-constellation GNSS receiver with a built-in high-gain antenna supports location reception, while Wi-Fi and Bluetooth provide wireless links for compatible phones, tablets, and computers.

The integrated 9-pin connector removes a separate-cable step for compatible trucks, and the multi-constellation GNSS receiver with high-gain antenna supports the device’s location function. Bluetooth 4.2 offers a wireless connection to compatible mobile devices, while Wi-Fi supports networking in access-point and station modes. Over-, under-, and reverse-voltage protection addresses vehicle power variations, and the low-temperature power supplies support operation in cold conditions. Confirm the vehicle connection and the required HOS app before installation.

Skip it if you need a listed OBD-II cable in the bundle; the Geosavi PT30 bundle with black square light-duty OBDII cable specifies one.

This suits an International truck operator seeking a built-in 9-pin connection and wireless connectivity for a compatible HOS setup. Check your vehicle port and app requirements before purchase; the supplied details do not name a particular logging app.

#9

9. PT30 9-Pin Cable

#10

10. TFM ELD

• Warranty Description: 1 Year Manufacturer

Best for: Minimal-detail ELD listing.

Why it ranks #10: The listing identifies an FMCSA-compliant truck ELD and IOSIX manufacturer, but supplies no port, protocol, app, or included-component details.

The TFM ELD listing identifies the product as an FMCSA-compliant electronic logging device for trucks, making its stated purpose clear for buyers seeking an ELD. Beyond that core description, the supplied information names IOSIX as manufacturer and gives a one-year manufacturer warranty, but provides little detail about ports or connectivity.

The title identifies this as an ELD for trucks and states FMCSA compliance, which establishes its advertised role as a logging device. The supplied specifications identify IOSIX as manufacturer and state a one-year manufacturer warranty. They do not describe a diagnostic connector, wireless link, phone app, storage behavior, or installation process, so buyers cannot assess those workflow details from the available product information. Verify the device’s connection and app requirements through product documentation before planning an installation.

Skip it if you need a confirmed port type and Bluetooth workflow before buying; TEMEDA PT 30 lists multiple ports and Bluetooth connectivity.

This listing may suit a buyer who needs a truck ELD and is comfortable seeking further setup details. It states FMCSA compliance, but the supplied information does not establish connector type, app compatibility, or installation steps.
