Abstract: The present invention relates to methods, tools and systems for manufacturing a durable and portable power-conditioned personal solar system charging apparatus. Various voltage and amperage matching algorithms are manipulated to particularize the personal solar system to power and/or charge an intended portable device or a set of intended portable devices having direct current (DC) load requirements. The optimized personal solar system that is matched to an intended device allows direct coupling to the intended device without the use of an internal battery or ancillary electronic circuit boards to distract the personal solar system output, and facilitates “fast” charging modes.
