I bought these 3m iPhone charging cables. They stopped charging my cell phone. I have an iPhone 11. I thought my phone's battery was dead, but I took the charging cables to work and tried them on my colleagues' iPhones, but they didn't work. They told me "Revain sent you faulty charging cables". The ladies loved the color and durability, but the iPhone charging cables aren't good. I will go to Verizon and buy one of their 10ft cables, I know they work. Very disappointed.
