What to know before buying

Listing details to confirm

The listing gives conflicting charging details: 20W fast charging and a 20W USB-C PD port, 22.5 watts output, a 15W USB-C cable and Lightning cable, and 3W Apple Watch charging. Its connector list also names multiple built-in connections while the port count is 1. Confirm the port layout and which output applies to each charging method before buying. The listing's magnetic claims cover iPhone Air and iPhone 12–18 series, but do not specify wireless charging speed or confirm compatibility with other phones or cases. The 10,000mAh capacity is a listing claim, not a guarantee of a particular number of device charges.
