Solar charger USB receiver for laptops

Abstract

The present invention is a USB receiver charger for laptops consisting of four internal layers and two external layers. The external layers feature a thin photovoltaic (PV) panel that captures both sunlight and artificial light, integrated on both sides of the USB. Internally, the first layer houses high-powered LED COB lights, illuminating the second layer—the PV panel. The PV panel absorbs light, converting it into electrical energy stored in a rechargeable battery. Excess power is stored in a power bank. The rechargeable battery distributes the energy, powering the LED lights and transferring the remaining power to the device being charged. A solar charge controller, PV energy converter, and temperature controller are included to regulate power distribution and prevent overcharging. The LED lights dim when the power bank reaches maximum capacity to prevent unnecessary energy generation. The USB, equipped with three PV panels, generating minimum 25 watts for efficient laptop charging.
