A portable solar mobile charging adapter comprises a USB female head, photovoltaic power generation modules, an anti-backflow diode D. The photovoltaic power generation modules are equipped with solar cell panels, anode wiring terminals and a cathode wiring terminals. The anode wiring terminals are connected with the anode of the anti-backflow diode D, the cathode of the anti-backflow diode D is connected with one pin of the USB female head, and the cathode wiring terminals are connected with another one pin of the USB female head. The photovoltaic power generation modules comprise frames used for fixing the solar cell panels, the side edges of the frames are equipped with rectangle frame rings and buckles, and the plurality of photovoltaic power generation modules are connected by connecting adhesive buckles. By combining the photovoltaic panels in series and parallel reasonably, the portable solar mobile charging adapter of the invention generates a charging current satisfying requirement. Meanwhile, the solar cell panels are made into a wearable square array which can be pasted on a knapsack or the back of the clothes of a traveler. The portable solar mobile charging adapter is light in mass and small is size, is green environmental protection and is convenient to carry.
