Thunderbolt cables and standard USB-C cables look very similar, but Thunderbolt cables support higher data transfer speeds and additional features. To identify a Thunderbolt cable, look for the lightning bolt icon on the cable or connectors. Thunderbolt cables often support speeds up to 40Gbps, while standard USB-C cables usually max out at lower speeds. Also, Thunderbolt cables may be more expensive and marketed specifically for high-performance tasks like video editing or connecting to multiple devices. Checking the product details or packaging can help confirm the cable type.

Yes, many USB-C cables can transfer data in addition to charging devices, but not all cables support the same data speeds. Some cables are designed primarily for charging and may have slower data transfer rates, while others support faster data protocols like USB 3.1 or Thunderbolt 3. When buying a cable, check the specifications to see if it supports data transfer and at what speed. This is especially important if you plan to use the cable for syncing files or connecting to external devices like monitors or drives.

Choosing the right USB-C cable length depends on where and how you plan to use it. Shorter cables (3 to 6 feet) are great for charging devices close to power sources like desks or nightstands, reducing clutter. Longer cables (10 feet or more) offer flexibility for use in larger spaces or when outlets are farther away. Consider your typical charging spots and device locations to pick a length that balances convenience with portability. Also, longer cables may slightly reduce charging speed, so keep that in mind if fast charging is a priority.
