This power supply works with 110V and 220/230/240V.
Unlike transformers, this power supply outputs DC voltage which has the great side effect that the voltage regulators and the heat sink on the Apple-1 PCB stay way cooler (approx. 40°C/105°F) which helps reduce stress on the parts.
The Molex connector has been professionally crimped for maximum durability.
PLEASE NOTE: The power supply comes with an EU plug. A travel adapter can be used to make it fit for US/AU/UK sockets in seconds.
