Confusion about iPhone 17 charger: 25W or 30W?

Hi there!

I've read all the information all over internet about the iPhone 17 and still don't understand which is the right W for the electric charger that I need to buy : 25w or 30w?

Thanks in advance!

Does it mean that I still can use the charger 33W from my old Xaomi that had the option for fast charging? I've never had an iPhone by now and don't know anything about the specifics.. Thank you!


You need to check that your Xaomi Power Adapter (charger) supports USB PD (Power Delivery). If it does support USB PD, then yes, it will be compatible with your iPhone 17.


Apple devices do not support other proprietary charging standards - such as QC (Quick Charge).

The first device in your post appears to be this one:


UGREEN – Power Banks – UGREEN Nexode 20000mAh 145W Laptop Portable Power Bank


"145W Fast Charge – Power Laptops in Minutes:Deliver up to 100W via USB-C and 145W total across all ports, charging your MacBook Pro, iPad Pro, or Galaxy Tab in record time. Whether you’re powering up before a flight or between meetings, stay fully charged without slowing down."


"Smart Protocol Support – Fast Charge All Major Devices:Supports PD, PPS, SCP, and UFCS fast-charging protocols, ensuring optimized charging for iPhone, Samsung, Xiaomi, Huawei, and more. Charge three devices at once—no more waiting."


I assume that "PD" stands for "USB-C Power Delivery." I wouldn't count on this device supporting it on its USB-A port, only on its USB-C cable and on its USB-C port.

Exactly! That's why I needed your suggestions guys. What brand and model of adapter to buy?


Purchasing Apple ensures high quality, reliability and compatibility.


High-quality third-party adapters are available. Mophie have good reputation here - and are directly marketed by Apple. Anker and Belkin are also well known - but you should verify support for USB PD prior to purchase.


Purchasing from a physical Apple Store, or the Apple online store, will always ensure compatibility with Apple devices.
