Micro USB will not charge Bluethooth portable speaker troubleshooting and repair Photive

I can't stand Micro USB, Micro USB is too fragile for portable devices. I have repaired at least a 100 devices with micro USB. I have yet to repair a portable device with USB-C. Even Mini-B was way better then micro USB.
