Very good charger. I use it on my iPhone 15 and so far I have no issues, neither the phone nor the charger increase temperatures. I did not find the light mentioned in the other comments annoying

Very good charger and quality construction. The light is indeed a bit intense, but not something annoying, if the socket doesn't face the bed when you sleep.

I use it on iPhone 12. Completely satisfied after two years of use. Recently, the LED light stopped working, but it remains fully functional. It charges the phone within the expected times provided by Apple. The temperatures are very close to the Apple charger, as I have both. Spigen is a reputable company with very nice and high-quality products at affordable prices.

I use it together with Apple's MagSafe for charging the iPhone 12. Very normal charging temperatures, small size, and very convenient to have with you for travel. The blue LED indicator it has is relatively intense. This is negative for those who don't want any light on their charger and have it next to their bedside table for overnight charging of their phone. On the other hand, if you have it in a hotel during a trip, you can also have it as a night light in a sense. Its price is very good. In the two months that I have it, it works flawlessly.

I bought the 13 without the transformer and was going for the original one. After a little searching, I ended up getting this one and it turned out to be much better than the original.

Excellent, fast, high-quality. The only drawback is that the blue LED it has is always on regardless of whether you have your phone connected or not. Otherwise, flawless
