SIMPSON PowerShot SPG7085E Overview
The SIMPSON PowerShot SPG7085E is a portable generator powered by a Honda GX390 engine, with a rating of 8,500 watts at startup and 7,000 watts while running, at 120/240V. It is designed to cover construction sites, tailgates and home backup, running tools, appliances, recreational gear and lighting from a rugged, mobile package.
The engine starts electrically using a 12V-14AH battery, which is not included, and low oil shutdown protects it. A 6.1-gallon fuel tank provides 8 hours of run time at 50% load. The heavy-duty roll cage frame shields internal components in tough conditions, while a foldable handle and 10-inch never-flat wheels make the generator easy to move and store. The panel provides six circuits/outlets, and its GFCI-protected outlets meet safety standards for jobsite and residential use. The generator measures 31.1 x 21.6 x 23.8 inches and weighs 191.8 lb. It comes with the Honda GX390 electric-start engine, the foldable handle and the 10-inch never-flat wheels. Sump pumps, heaters and tool charging stations are natural companions for jobsite or home readiness, and SIMPSON transfer switches, heavy-duty extension cords and portable lighting kits can round out the setup.
