High energy and efficient solar charging stations using electrochemical capacitors (ECs) are a promising portable power source for the future. In this work, two kinds of metal‐organic framework (MOF) derivatives, NiO/Co3O4 microcubes and Fe2O3 microleaves, are prepared via thermal treatment and assembled into electrochemical capacitors, which deliver a relatively high specific energy density of 46 Wh kg−1 at 690 W kg−1. In addition, a solar‐charging power system consisting of the electrochemical capacitors and monocrystalline silicon plates is fabricated and a motor fan or 25 LEDs for 5 and 30 min, respectively, is powered. This work not only adds two novel materials to the growing categories of MOF‐derived advanced materials, but also successfully achieves an efficient solar‐ECs system for the first time based on all MOF derivatives, which has a certain reference for developing efficient solar‐charge systems.
