The A-iPower GXS4500iRDC inverter generator has a high-performance 149cc OHV Engine, is EPA, cETL, and PGMA-compliant, and includes a CO sensor that monitors and reacts to carbon monoxide (CO) levels, automatically shutting down if levels are too high. Offering the choice of operating with gasoline or propane or both with fuel sense technology, the unit has 4500 starting and 3900 running watts on gas, and 3,450 starting and 3,100 running watts on propane. The 1.6 gal. fuel tank provides up to 7.5 h of runtime while using a 20 lb propane cylinder gets up to 18.5 h of runtime. Extended continuous runtimes of up to 26 h are available with fuel sense technology. It also has low idle technology, as it adjusts RPM based on demand, saving fuel. Providing <3% THD of clean power and at 63.9 lb, the ultra-lightweight inverter has an LED-equipped control panel and parallel capability. Featuring quiet operation, as low as 62 dB, making it ideal for home, camping, tailgating and RVing, the digital data centre provides voltage, frequency, hours, power and fuel levels, output/overload/oil level status along with fuel-saving low idle and reset functions.
