⛽ Maximum Fuel Efficiency

Do more with less. The Westinghouse 212cc OHV engine gets the most out of every liter:

• Gasoline: 4,200W (Peak) / 3,500W (Running)
• Run time up to 18 hours(10L fuel tank at 25% load)
• Run time up to 15 hoursat 50% load
• Efficiency Mode: automatically reduces engine speed based on demand — less fuel, less noise

⚡ Inverter Technology & Active Load Response

What sets the iPro4200 apart from a conventional generator:

• Clean power < 3% THD— pure sine wave, safe for all sensitive electronic equipment
• Active Load Response (ALR): variable engine speed adjusted in real-time to the active load
• Pulse-Flo™ Muffler + variable speed: noise level as low as 62 dBA
• Open frame: only 37 kg (82 lb) — inverter power in a portable format

🔌 Full Jobsite Panel

Everything you need, no adapter required:

• 3x GFCI 120V AC 20A 5-20Routlets with covers — OSHA compliant
• 2x 5V DC USBports with cover — charge your devices directly on the jobsite
• VFT Meter: real-time volts, frequency, and cumulative hours
• Individual 20A circuit breakers per outlet
• Overload reset button (RESET)

🛡 Professional Safety & Compliance

• OSHA Compliance: full GFCI panel — required on jobsites
• CARB & EPA Compliance: certified in all provinces and states
• Low oil shutdown protection: automatic shutdown to protect the engine
