The purpose of this study was to design the Portable LED Lamp to overcome the problem of the need for power sources and lighting for outdoor activities such as camping, mountain climbing or long trips. The equipment is made up of solar cells that charge the charger through a charge controller to turn on the LED light or recharge the phone battery. The method used in this research is float charging by using the main components of LM7805 voltage regulator. The charger battery used is Li-Ion (Lithium-Ion) which is cheaper, easy to maintain and does not contain harmful substances so it is quite safe when compared to Ni-Cd (Nicke-Cadmium) and Ni-MH (Nickel-Metal Hydride). The advantages of this made system is the lithium battery can be recharged its electric charge by using solar cell power source and PLN power grid.
