Generac GP15500EFI Portable Generator Features

High-Efficiency Power Delivery for All Needs

The 816cc Generac EFI engine ensures reliable power output with optimal efficiency. It runs smoothly for up to 11 hours at 50% load, saving on fuel costs while allowing prolonged operation during emergencies or demanding projects.

Stay Safe with Smart CO Monitoring

COsense® Technology continuously checks carbon monoxide levels and issues alerts if they become too high. This crucial feature can also shut down the generator when needed, protecting you and your family from potentially harmful gas exposure.

Quick and Easy Engine Starts

The electric start feature, with battery included, offers effortless start-up each time you use the generator. This user-friendly design means you spend less time struggling with pull starts and more time powering what’s essential.
