Learn how to replace your car mount charging cable with a Quad Lock USB A to USB C cable. Step-by-step guide with length selection tips and common mistakes to avoid.

Quick answer

Replace your car mount charging cable by selecting the right Quad Lock USB A to USB C cable length, unplugging the old cable, and securely connecting the new one to your power adapter and phone mount.

Why cable length matters for your car mount

A cable that's too short strains the connection and limits where you can place your phone. One that's too long creates clutter and can interfere with driving. Quad Lock offers three lengths: 20 cm (8 inches) for motorcycle use, 1.5 m (4.9 feet) for car and desk setups, and 2 m (6.5 feet) for extra reach. For most car mounts, the 1.5 m cable provides a clean, tangle-free fit from the power outlet to the mount.

Compatibility check before you buy

The Quad Lock USB A to USB C cable works with any USB-A power adapter and USB-C device. If your car mount uses a different connector or your phone requires USB-C to USB-C, this cable won't fit. Verify your power source and phone port before ordering.

How to replace your car mount charging cable

Select the correct cable length: Measure the distance from your car's USB-A power outlet to your phone mount. Add a few inches for slack. Choose the Quad Lock USB A to USB C cable length that matches: 20 cm for very short runs, 1.5 m for most cars, or 2 m for rear-seat or truck setups. Common mistake: guessing the length. Measure first to avoid a cable that's too tight or too long.
Disconnect the old cable: Unplug the existing cable from both the power adapter and the phone mount or phone. Remove any cable clips or organizers holding it in place. Checkpoint: note how the old cable was routed so you can replicate the cleanest path.
Connect the new cable to the power adapter: Plug the USB-A end of the Quad Lock cable firmly into your car's USB-A power adapter. Ensure the connection is fully seated to avoid intermittent charging. Common mistake: not pushing the connector all the way in, which can cause a loose fit and power loss.
Route the cable to your phone mount: Run the cable along the same path as the old one, using clips or adhesive mounts to secure it. Avoid sharp bends or pinching in seat rails and glove box hinges. Checkpoint: test that the cable reaches the mount without pulling on the connector.
Connect the USB-C end to your phone or mount: Plug the USB-C end into your phone or the mount's charging port. If your mount has a built-in cable, connect the Quad Lock cable to it. Confirm the phone starts charging. Common mistake: using a mount that doesn't support USB-C pass-through. Verify compatibility before finalizing the connection.
