I buy some micro USB line from chinese on 1688. Their color is blue. And with Anti electromagnetic interference,Industrial grade.
They have different lengths . 30cm,50cm,1.5M.
But 30cm and 50cm always bad connection!
Only 1.5M is normal.
Their differences in a wrong design micro connector .
The Micro USB connector of Bad connection is Wrong design. No groove to connection.
