Using an uncertified power supply and USB-C cable can cause lasting harm to new Apple smartphones in the iPhone 15 series. Industry reports highlight concerns raised by Jessa Jones, who runs a repair service specialized in iPads and related devices.
Jones notes that counterfeit chargers and cables do not include the protective features built into authentic Apple accessories. Without these safeguards, the risk of damage increases, especially during power surges or other electrical irregularities that can affect the device’s internals.
She explains that high‑end chargers function as compact electronic hubs with miniature circuits and components. For instance, Apple’s official Lightning cable contains two chips: one that confirms the accessory meets the vendor’s standards, and another that acts as a fuse. This setup helps keep the phone powered during minor voltage fluctuations while limiting harm to the charger itself. In practice, this means the charger bears the brunt of a fault, not the phone.
Jones further cautions users about the potential dangers of plugging uncertified accessories into public power sources. This includes outlets found in hotel rooms, on airplanes, inside car charging ports, and other shared or exposed power endpoints where variability in voltage and quality is common.
Earlier warnings have also circulated about scam sites targeting iPhone 15 buyers, underscoring the importance of sourcing devices and accessories from reputable retailers and verifying product authenticity before making a purchase.
