Abstract: A portable generator set (1) comprises an engine (6), a generator (7), a fuel tank (8), and a housing (5). The engine (6), the generator (7), and the fuel tank (8) are accommodated in the housing (5). The fuel tank (8) is constructed by a fuel tank housing (805), a fuel tank port (801), a fuel tank cap (802), and a fuel tank top surface (808). A protrusion structure protruding outward is provided on the fuel tank top surface (808). A hollow cavity (809) communicated with the inner cavity of the fuel tank (8) is formed on the inner side of the protrusion structure, such that fuel in the fuel tank (8) can enter the hollow cavity (809) when the generator set (1) is obliquely reclined. The generator set can be obliquely reclined, thereby improving security and facilitating transportation and storage of the generator set.
