Featuring a compact design with a durable frame, this generator is built to withstand tough job site conditions while providing reliable power wherever it is needed.

One of the standout features of the 3914 model is its powerful 212cc engine, which delivers a peak output of 3500 watts and a running output of 3000 watts. This allows users to power multiple devices simultaneously, making it suitable for everything from household appliances during power outages to tools on construction sites.
