Are the Lightning cable/connector dimensions the same as Apple Lightning Cable?

Yes. The dimensions are the same. Thank for your choosing K123 Keytech. Here is some advice how to use our cable properly
1. The Lightning connector is not waterproof. Please avoid storing your cable in high-humidity environments. Unplug the cable from the adapter when not in use.
2. To ensure longevity, do not abruptly bend or pull the connector. Do not exposure your cable to the elements for long periods of time, allowing the connector to collect moisture and rust.
3. Keep your cable away from pets.
4. Use 99% v/v alcohol to clean the Lightning connector surface occasionally.
