Konner&Sohnen Könner & Söhnen 5500W Dual Fuel Inverter | LPG/Gasoline, Electric Start, CO Sensor | KS 6000iEHS CO

- GAS OR PROPANE, OUT OF THE BOX: Run on gasoline for full power or propane for storage that never goes stale - the propane hose and regulator are in the box. Switch fuels to suit the job or whatever you can get during an emergency.
- REAL POWER, CLEAN POWER: 5,500 starting / 5,000 running watts on gasoline (about 10% less on propane - roughly 4,950 / 4,500), delivered as a pure sine wave at less than 3% THD. Clean enough for laptops, TVs, and a CPAP; strong enough for power tools and a well or sump pump.
- PUSH-BUTTON START, HOURS OF RUN TIME: Electric start with recoil backup, plus a 3-in-1 start dial that combines fuel valve, choke, and start in one motion. 6.8 hours at 50% load on a single 2.9-gallon tank of gas — or run off your propane tank for the long haul.
- CONVERSATION-QUIET, RAIN-READY: 58 dB at 25% load (23 ft / 7 m) inside a fully enclosed soundproof housing - around the level of a normal conversation. IP23M-rated to keep running through rain and spray. 
- BUILT-IN CO SAFETY + U.S. SUPPORT: Automatic carbon-monoxide shutoff plus low-oil and overload protection. German-engineered, 3-year limited warranty, and U.S.-based service you can call directly.
