Q1: Can I use both the 110V and 220V output sockets at the same time?
A: Yes, as long as the total combined wattage of both connected appliances does not exceed the maximum power rating of the transformer.
Q2: Do I need to manually switch the voltage on the back before plugging it in?
A: YES! Always check the rear voltage switch before connecting to power. Set the switch to match your local wall socket voltage (e.g., set to 220V in Europe/China, or 110V in US/Japan).
Q3: What plug type comes on the power cord?
A: We supply region-specific input power cords (US Plug, EU Plug, UK Plug, AU Plug) based on your target shipping market or OEM requirements.
