The Essential OBD2 Splitter Buying Guide

So, you’re looking to get more out of your car’s onboard diagnostics system. That’s where an OBD2 splitter comes in handy! These little gadgets let you connect multiple devices to your car’s single OBD2 port. This means you can run a scanner and a dashcam, or a performance monitor and a GPS tracker, all at the same time. But not all splitters are created equal. Let’s dive into what you need to know to pick the right one.

Key Features to Look For

When you’re shopping for an OBD2 splitter, keep these important features in mind:

  • Number of Ports: Most splitters offer two or three ports. Think about how many devices you’ll need to connect simultaneously. Two ports are often enough for basic needs, but three might be better if you plan on running more gadgets.
  • Cable Length: The length of the cable connecting the splitter to your OBD2 port matters. A longer cable gives you more flexibility in where you place your devices. You don’t want the cable to be too short and pull on the port.
  • Durability and Build Quality: You want a splitter that will last. Look for sturdy construction and good quality connectors.
  • Compatibility: Most OBD2 splitters work with standard OBD2 protocols, but it’s always a good idea to check if your specific car model and the devices you plan to use are compatible.
  • Right-Angle or Straight Connectors: Some splitters have angled connectors, which can be helpful if your OBD2 port is in a tight spot.

Important Materials

The materials used in an OBD2 splitter affect its performance and lifespan.

  • Wire Gauge: Thicker wires (lower gauge number) can handle more electrical current, which is important for devices that draw more power.
  • Connector Material: Good quality connectors are usually made of durable metal alloys that resist corrosion and ensure a secure connection.
  • Cable Sheathing: The outer protective layer of the cable should be flexible and resistant to wear and tear. PVC is common, but more robust materials might be found in higher-end models.

Factors That Improve or Reduce Quality

Several things can make an OBD2 splitter better or worse.

What Makes a Splitter Better?
  • Solid Construction: A well-built splitter with securely attached connectors and a robust cable feels more reliable.
  • Proper Wiring: Internal wiring that is neatly done and uses appropriate gauge wires ensures good signal transmission and power delivery.
  • Shielding: Some higher-quality splitters have shielding to protect the signal from electrical interference, which is crucial for accurate data readings.
What Can Make a Splitter Worse?
  • Loose Connectors: If the plugs feel wobbly, they might not make a good connection, leading to intermittent issues.
  • Flimsy Cable: A thin, easily kinked cable can break or fray over time, damaging your devices.
  • Poor Internal Wiring: Crossed wires or cheap solder joints can cause communication errors or even damage your car’s electronics.

User Experience and Use Cases

Using an OBD2 splitter is generally straightforward. You simply plug one end into your car’s OBD2 port, and then plug your devices into the other ports on the splitter.

Common Use Cases:
  • Performance Monitoring: Connect a Bluetooth OBD2 adapter for your smartphone app and a dashcam simultaneously to track your driving habits and record your journeys.
  • Diagnostic Scanning: Keep a diagnostic scanner plugged in while also using a tire pressure monitoring system.
  • Multiple Gadgets: Power a GPS tracker, a radar detector, and a dashcam all at once.

The experience is usually seamless. You plug it in, and your devices work as they should. However, if you encounter issues like slow data transfer or devices not being recognized, it might be a sign of a poor-quality splitter.
