10 reviews for Scosche Universal 5.ft USB Hard Wire Kit with 18W USB-A QC 3.0 Port and OBDII Connector OBD2QC3-SP

  1. kdc

    Using this to power a 15W phone charger on a 2023 Rivian R1S.Works great, charges fast for my application.Note that whether it’s always on or switched power will depend solely on your vehicle’s OBD2 port power, as does voltage. Check the specs on your vehicle to know whether this will meet your specific need.

  2. Nestor Aparicio

    I was going to install a new garmin 67w dash cam in my dad’s 01 Ford Excursion and was looking for an alternative to the $50 garmin obd cable. And a Google search got me to the scosche obd adapter cable. Installation was a breeze without splicing any wires. It works with the garmin dash cam perfectly. No errors or issues with current draw after the car is off. If you’re on the fence about this just get it. For the price the quality and functionality, you can’t beat this.

  3. Stephen Kaselak

    I used this to install a dash cam in my daughter newer car and it worked great. Did not work as described for my sons older car.

  4. Dave Machete

    Worked for what I needed, but be aware, it is not constant voltage. It will power down when the vehicle is shut off, and it’s fairly inexpensive. However, if you’re looking to quickly add a USB port to save from using one on the dash, easy addition. If you’re looking to power a dashcam when the vehicle is parked, this is not the right one to buy.

  5. G. Cook

    This product is always on. If so you will have battery drain if you use it on a camera etc. They should have a timer on it. It fine for charging a cell phone etc.

  6. Bob L

    Great way to solve a silly problem of not having a USB port under the dash of a Rivian without having to to any major changes, works flawlessly

  7. Justin S.

    Neither worked. I tested the non OBD II on a fresh test battery. Good power and ground all the way to the module. I tested my OBD II and hand good power and ground all the way to the module. No power out from there. Bad units!

  8. Alex R.

    Excellent little device to power my dash cam worry free

  9. Sankar

    I returned this product thinking it was a faulty device. But looks like my Rivian was constantly powering it. Good thing is it still has an OBD port open if you still need it.

  10. J-Rod

    Used in my Rivian R1s and works great to provide power to my phone.
