Just received Samsung Galaxy S10e. I bought these charging cables to have in my office, car and bedroom. I'm not sure if I ever had any defects but they barely charge my phone like they should. I tested the original charging cable, which charges my phone from 30% to 100% in about 45 minutes. These charging cables are of good quality but it takes a long time to quickly charge my new phone. Just a note if you have high hopes for fast charging.
