I have iPhone 15 pro max, this charger works with my phone. I got this for my husband, he has iPhone 14 and it works with his phone. The problem is that you have to make sure your plug-in is 2A or above, which I personally never even heard of before until I've read the instructions that came with this charger. This charger states it's a fast charger but in order to achieve that you'll need a higher power adapter. I didn't have it, so my phone was saying it's a slow charger, my battery was at 48% and that it will take 45 minutes to charge to 80%. That is fine for my husband because he charges his phone at night when going to bed. The charger looks good, it's round, pretty flat, doesn't take up much space. The only problem I have with this is that I will need to purchase another outlet extender with USB A plug with a 2A or above socket because I just borrowed it from another device and another plugin I have doesn't work with this charger because its output is too low. Otherwise it's a good charger. USB C end goes into the charger and USB A into the plugin in the wall. USB A is a larger end in case you're not sure.
