3.1 Connection Methods
The Laptomo S1 offers various connection options depending on your laptop's ports:
Option 1: Full-Featured Type-C Connection
If your laptop has a full-featured Type-C port (USB 3.0 or higher with video output), a single USB-C to USB-C cable is sufficient for both video and power. Connect one end of the USB-C to USB-C cable to the labeled Type-C1/C2 port on the S1 and the other end to your laptop's full-featured Type-C port.

Option 2: Type-C to HDMI + Type-C to USB-A Connection
For laptops lacking a full-featured Type-C port but equipped with USB-A and HDMI ports, use two cables: a Type-C to HDMI cable and a Type-C to USB-A cable. Connect the Type-C end of the HDMI cable to the labeled HDMI port on the S1, and the HDMI end to your laptop's HDMI port. Then, connect the Type-C end of the USB-A cable to the Type-C1/C2 port on the S1, and the USB-A end to your laptop's USB-A port.

Option 3: Type-C to HDMI + External Power (if needed)
If your laptop's power output is insufficient, you may need to use an external power source. Connect the Type-C to HDMI cable as described in Option 2. For power, connect an additional Type-C to USB-A/Type-C cable from the S1's Type-C1/C2 port to an external power source (e.g., a power adapter or power bank).
