Faulty 8 pin results


Recently had a iPhone fail do to poor charging cable. I tested the cable with the qoopow basic and it showed a flashing re light indicating a faulty cable that should not be used. But then I tested all my other 8 pin cables including a brand new one straight out of the box of my new iPhone X-ray (never been used before) and they all showed the same result. All other cables (micro USB etc) passed with flying colours. What is going on. Any ideas?


Hi Mryan,

I am very sorry to reply you late!

Apple uses a mechanism to prevent fake lightning cables. There is a chip inside the head of the lightning plug side, which will communicate with the iDevices. It will turn on a MOSFET switch to enable the charging if it passes the communication. Thus, in order to measure the lightning cable, the qualMeter needs to simulate the communication with the cable to fool the inside chip to turn on the MOSFET switch.

However, since it’s a simulation, it might not work if Apple changes the way(or the code) of communication. Then you would experience the problem like what you have described above. The indication you’ve got might lead to the following results:

  1. The cable could be broken.
  2. If qualMeter was not able to test it and you are sure the cable is good. Then it could be a newer version lightning cable that our qualMeter has failed to communicate with it and is unable to test it.
  3. If so, following the 2nd result, your lightning cable should be a genuine Apple certified lightning cable.
  4. As far as I can tell, a 3rd party non-Apple-certified lightning cable or older version genuine lightning cable should have no problem to be tested normally as other cables on the qualMeter.

Thank you for letting us know. This situation is something new to us. It was okay for the past 3 years. We need to look into it and to see if we can find a solution for it.

Thanks again!
