Yes, the iPhone 15 has USB-C. But no fast charging over USB-A — max 12 W. Fast charging needs USB-C to USB-C and a USB-PD adapter.
Yes, if the cable is rated as a data cable. USB 3.2 Gen 1 with 5 Gbps data transfer is standard for good models.
USB-A is the big rectangular classic. USB-C is the small, reversible new plug — fits both ways, higher power and data rate.

Guide & know-how
USB-C to USB-A cables at RPD for modern Android phones (Galaxy from S8, Pixel, Xiaomi, Oppo, Huawei), iPhone 15+, USB-C iPads, Nintendo Switch and USB-C power banks that you want to charge at USB-A adapters, older PCs/laptops, car sockets or in a hotel room. Over USB-A the cable charges at up to 18 W (5 V / 3.6 A) with Quick Charge 2.0/3.0 — for USB-PD fast charging on a smartphone you need USB-C to USB-C. Data transfer at USB 3.2 Gen 1 (5 Gbps) on properly labelled cables — ideal for phone-to-PC backups and external SSDs. Nylon braids in 0.5 m, 1 m, 2 m and 3 m. Same-day dispatch from Basel, 2-year Swiss warranty, free above CHF 15. Invoice payment available (credit check by Powerpay).
USB-C devices you want to charge at a USB-A port: Galaxy S8 to S25, iPhone 15+, iPad Pro/Air/Mini from the 2018 generation, Pixel, Xiaomi 11+, Huawei P40+, Nintendo Switch, USB-C power banks, many Bluetooth headphones (AirPods Pro 2 USB-C, AirPods 4, Sony, recent Bose). If your adapter has a USB-C port, prefer USB-C to USB-C — that's the only variant with USB-PD fast charging.
Plugging a USB-C phone to USB-A adapter charges at a max of 5 V / 2.4 A = 12 W, up to 18 W with Quick Charge. USB-PD fast charging (20+ W) only happens over USB-C-to-USB-C. Data rate depends on the cable: cheap models USB 2.0 (480 Mbps), better USB 3.2 Gen 1 (5 Gbps), premium USB 3.2 Gen 2 (10 Gbps). Check the data rate before buying if you plan phone-to-PC backups or external SSDs.
The USB-C plug is reversible — fits both ways, no more wrong-way fumbling. Mechanically much more robust than Micro-USB. Nylon-braided cables with aluminium connector housings and strain relief last twice as long as plain PVC. Bend tests run to 10,000–30,000 cycles. For car and travel we recommend braided models.
0.5 m for power bank in backpack and phone mount in car, 1 m standard for bag and travel, 2 m for sofa, bed and desk, 3 m for longer reach. Longer cables have slightly higher resistance — at 12–18 W via USB-A practically negligible.
