Three or more portable generators are linked for synchronized operation. Power cables link each generator to a linkage box which connects the power in parallel and connects an outlet thereto. Communication cables link a software module in each generator with the linkage box. The modules vary the generator operation to generate a voltage amplitude and phase matching that of the first generator that is connected to the box that begins power generation, so that all generators share the load equally until their power output limits are reached.
