Power Supplies & Plug-in Adapters for Electronics Projects

Power supply units are required for devices that rely on voltages or currents other than those provided by the mains supply. They are available for DC or AC voltage and constant current as switching, transformer or capacitor power supplies. They are often used to charge laptop or smartphone batteries, while other devices can generally only be used in mains operation. Depending on the project you want to tackle, choosing the right power supply plays a decisive role.
