How does this dock improve display performance for handheld gaming?

The unit ships with a 65W PD charger suitable for steady gameplay on most supported handhelds and includes the capability to accept up to 100W PD input for heavier setups. For prolonged sessions with Turbo Mode or several peripherals attached, a 100W PD adapter can be used to ensure consistent power delivery.
