Our line of Breeze Extended Run Generator System (BERGS) is a simple way to extend the run time of a suitcase style generator. Our system does not modify or destroy your current cap. The Breeze Run Generator System uses a vacuum draw system; no need to elevate a gas can above the generator. Our patented product will extend the run time of the generator by up to 72 hours; thus allowing the end user to set it, start it, and forget it! May not fit the older style EU2000.
