1. A table lamp, comprising:
a base structure containing electrical components;
at least one light source connected to the base for illumination;
at least one USB Type-A port or one USB Type-C port, provided in the base and configured to deliver direct current (DC) power to external electronic devices;
a wireless charging module positioned in the base, and configured for inductive charging of compatible electronic devices;
a rectification circuit configured to convert incoming alternating current (AC) from a main power source to direct current (DC) output for use in the USB charging ports and wireless charging module, wherein the rectification circuit includes a voltage regulation module configured to maintain a consistent DC output, wherein the voltage regulation module comprises a feedback loop mechanism that continuously monitors the output voltage and adjusts it to maintain a fixed DC output of 5 volts at the USB Type-A port and a variable DC output of up to 20 volts at the USB Type-C port.
