Why does the I-1 have two cables?

The I-1 comes with two cables. It has an USB charging cable and an USB data cable.
The USB charging cable is a dedicated cable that you should use to charge the I-1. A full charge usually takes just 1.5 - 2 hours when you use this cable together with a smartphone power adapter or computer USB port. It has been optimized for quick charging and cannot be used for data transfer.
The USB data cable is a dedicated cable for data transfer between the I-1 and a computer. Please only use it if you need to update your camera’s software.
