How exactly does an Evoline port operate?
From a retracted position you would push gently on the metal disk and tip it. Placing your fingers under the rim of the lid you lift the device up to expose the power/data outlets. The unit can be opened to expose one or all of the outlets. You would plug your device into the power/data unit and either continue using the device in the open position or return the device to the retracted position. Once retraced the top remain in the tipped position allowing any connected cables to remain in place and slightly gripped to prevent loosening.
