A generator assembly suitable for being carried on the back of a human comprising an internal combustion engine an alternator and a shaft driven by said engine and driving said alternator wherein when said generator assembly is being carried on the back of a human said shaft is substantially parallel to a longitudinal axis of said human. This enhances the manoeuvrability of the assembly. Preferably the assembly comprises a generator module having an engine and an alternator coupled directly by a common shaft, the generator module being attached to a frame of the assembly at only two longitudinally spaced-apart positions.

A power generation device capable of ensuring assemblability and ensuring strength/rigidity necessary when being handled, and having reduced size and weight, without using a reinforcement frame. The power generation device includes, in a casing, an alternator that generates power through driving of an engine, an inverter case that houses an inverter of the alternator, and a fuel tank that stores fuel for the engine. The device includes an upper fixing part that fixes an upper part of the fuel tank to the casing, an intermediate fixing part that fixes a lower part of the fuel tank to an upper part of the inverter case, and a lower fixing part that fixes a lower part of the inverter case to the casing.
