The cable included in the box is a USB-A > USB-B 3.0 cable. See figure 1.

Some laptops doesn't have a USB-A port, so a USB-C to USB-A converter will be needed in many cases. See figure 2 for an example. This cable is not included in the box, as it is seen as an optional accessory.
Many laptops are charged using USB-C. Be aware that Solvo connected to a laptop using USB-C, will not be able to charge a laptop. This meaning that a charger will have to be connected on an additional USB-C port, or using an adaptor with both USB-C connector (for charging) and USB-A 3.0 connector (for Solvo). See example of an adaptor like that on figure 3.
