In summary, external adapters have added much needed flexibility for engineering designs. Using both wall and desktop adapters, engineers can design smaller, more efficient products. They provide the flexibility of removing AC voltage from inside of a product and placing it outside of the product. Wall adapters with interchangeable plugs and desktop configurations allow the same adapter to be used in several countries, reducing part number count. Kaga Electronics provides several level V compliant adapters, resulting in a more efficient use of a valuable resource and eco-friendly designs in a cost effective package.
