dc 5 volt adapter
The DC 5V adapter is made not only of a small thing, but also an electricity converter;It converts AC from higher - voltage wall sockets to a steady 5v DC output.Featuring highly developed technology, this adapter takes care to ensure that the voltage will remain precisely at a certain level characterized (thus suitable for broad ranging electronic devices).The main functions include: providing power to those ready 5-volt devices; shielding from sudden changes in voltage and at the same time trying to be energy efficient.With the adapter comes short - circuit protection, over - voltage protection, and intelligent current regulation.General applications of such an adapter may include feeding power to smart phones, tablets, and other USB-powered devices such as portable speakers as well as LED light units.
