Charging iPhone and AirPods only: USB 2.0 USB-C to USB-C with PD 20–60 W is enough. iPad Pro with Pencil and external SSD: USB 3.2 Gen 2 (10 Gbps) with PD 60 W. MacBook + 4K or 5K monitor + USB hub: USB4 or Thunderbolt 4 (40 Gbps) with PD 100 W. Full display bandwidth and data rates only come with the correct standard — cheap uncertified cables often deliver only USB 2.0 despite the USB-C plug.
USB 2.0 = 480 Mbps + PD up to 240 W — charge cable, no fast data. USB 3.2 Gen 2 = 10 Gbps + PD 100 W — external SSDs and standard monitor. USB 3.2 Gen 2×2 = 20 Gbps. USB4 = 40 Gbps + PD 240 W + DisplayPort 2.1 Alt Mode — current MacBook M2/M3/M4. Thunderbolt 4 = USB4 + guaranteed 40 Gbps, 2× 4K or 1× 8K, MFi-certified. Thunderbolt 5 = 80 Gbps (M4 MacBooks). Lengths: 40 Gbps only up to 1 m passive, longer cables must be active (built-in chip).
MacBook Pro M2/M3/M4 has 3× Thunderbolt 4 / USB4. MacBook Air M2/M3 has 2× Thunderbolt 3 (40 Gbps). iPad Pro M4 (2024) also Thunderbolt 4. iPhone 15/16/17 = USB-C, Pro models with USB 3.0 (10 Gbps), Standard with USB 2.0 (480 Mbps). Android flagships (Galaxy S25, Pixel 9, Xiaomi 14): USB 3.x with PD 25–45 W. For pro photogrammetry or video: a short USB 3 cable to an iPhone Pro enables direct ProRes export.
Premium cables have braided nylon jackets for long life (10 000+ bends) and aluminium connectors that dissipate heat. USB-IF certification and an E-Marker chip for 60 W+ PD are mandatory — cheap cables without E-Marker charge only at 60 W, not the 100 W of a MacBook Pro 16″. CE-EMC and RoHS are standard, some brands use recycled copper and PCR plastic.
