Inside the Switch 2 Ac Adapter: Teardown, Vrr Dock Power Delivery, and Real-World Tests
By Maya Lin-Takahashi
The original Switch became infamous for bricking when connected to non-compliant third-party docks that mismanaged Power Delivery handshakes or bridged the M92T36 power management IC. The Switch 2 handles physical interconnects far better thanks to an industry-standard controller, but third-party dock compatibility presents a new set of power-budget challenges.
Accessories like the Jsaux 6-in-1 dock for Switch 2 incorporate their own internal power sinks. Between an integrated Gigabit Ethernet port, dual USB 3.0 lanes, an SD card reader, and an active DisplayPort-to-HDMI conversion chip, the hub itself consumes between 7W and 12W before routing any power to the console. If a player feeds this setup using an older 45W adapter or a budget smartphone charger, the console fails to enter docked mode entirely.
Hardware testing using the Jsaux 6-in-1 dock shows that passing adequate wattage requires an input supply of at least 65W, while utilizing every USB port concurrently demands an 87W to 100W power brick. When supplied with the official 65W Nintendo adapter, the Jsaux dock successfully delivers 50W to 53W directly to the console, just barely clearing the margin required to prevent battery drain during extended 4K gaming with VRR enabled.
