⭐⭐⭐⭐⭐ "Excellent value for money and very efficient charging!" I bought this pack of 2 MagSafe chargers from TNDAJI and I couldn't be more satisfied. I love that it includes USB-C to USB-A adapters. This allows you to use them with both modern and traditional charging cubes, which is a great detail. The magnet adheres perfectly to my iPhone and does not release easily, allowing me to continue using the phone while charging. The blue light ring gives it a modern and elegant touch, in addition to helping to locate the charger easily in the dark without being annoying. The 15W works wonderfully. Charge my AirPods and phone quite fast for a wireless connection, and I haven't noticed excessive heating. For the price of an original one, you get two high-quality chargers with their adapters. Super recommended to have one in the office and another on the bedside table!"
