Detailed Review
The Pulsar Products GX400BN is a portable dual-fuel generator designed for emergency home backup power and outdoor use. Powered by a 5.5HP 149cc engine, it provides a flexible electricity supply by running on either standard gasoline or liquid propane.
When running on gasoline, the unit produces 4000 peak watts and 3200 running watts. Switching to propane gives you 3600 peak watts and 2800 running watts. It is also RV-ready and features parallel capability, giving you the option to link compatible units together for additional power needs.
For everyday convenience, the generator features a built-in trolley design to assist with moving it into place. It operates at around 62 decibels under a half-load, which keeps running noise lower during use compared to full-load operation.
