Jefferson Tools JEFGENPET30 3.8kVA Petrol Generator 3.0kW AVR Recoil Start

When the job is outdoors, off-site, or simply too far from a reliable socket, the Jefferson 3.8kVA Petrol Generator is built to keep work moving. It provides dependable portable power for trades, farm maintenance, mobile repairs, and backup situations where consistent electricity is needed for tools, lighting, chargers, and essential equipment.

Powered by a MacGen 7.0HP petrol engine, this generator delivers up to 3.8kVA / 3.0kW maximum output, with a strong 3.3kVA / 2.6kW rated output for steady running loads. This balance makes it ideal for everyday site use, where reliable performance matters more than oversizing and unnecessary fuel consumption.

Clean, stable power for modern equipment

Many modern tools and appliances perform best with consistent voltage. Built-in AVR automatic voltage regulation helps smooth power delivery, supporting stable operation for equipment that may be sensitive to fluctuations. Starting is simple and familiar thanks to the recoil start system, allowing quick setup wherever work takes place.

Output options that suit real-world site needs

The Jefferson 3.8kVA generator is designed for flexible use across different environments, offering common site voltages for trade and maintenance work:

• AC Output: 1 × 230V 16A socket and 1 × 110V 16A socket

• DC Output: 12V / 8.3A for charging and auxiliary power needs

Longer running with fewer interruptions

A 15-litre long-run fuel tank supports extended operation, with a published running time of up to 11 hours, helping reduce downtime and refuelling interruptions during longer tasks or power outages.

Built-in protection for peace of mind

For added engine protection, the generator includes a low oil alert and low oil shutdown system, helping prevent damage if oil levels drop during operation and extending engine life.
