Job Site JS3400i 3.4kW Petrol Inverter Generator 230V | Recoil Start
The Job Site JS3400i 3.4kW Petrol Inverter Generator provides clean, stable and dependable portable power for emergency backup, home standby, outdoor activities and light professional applications.
It delivers a maximum output of 3.4kW and a rated continuous output of 3.1kW, making it suitable for powering compatible household appliances, lighting, tools and electronic equipment.
Clean Inverter Power
The generator uses inverter output technology to produce a stable electrical supply with waveform distortion of less than 2.5%.
This cleaner output makes it better suited than a conventional generator for compatible sensitive equipment, including:
- Computers and laptops
- Televisions
- Mobile-device chargers
- Electronic controls
- Audio and communication equipment
The total connected load must remain within the generator’s rated 3.1kW output.
230V AC and 12V DC Output
The JS3400i provides:
- 230V AC output
- 50Hz frequency
- 12V / 8.3A DC output
The DC output can be used for compatible low-voltage equipment or battery-charging applications when used with the correct connection equipment.
Reliable Petrol Engine
The generator is powered by a YF170FD 192cc four-stroke OHV petrol engine.
Its forced-air cooling system supports reliable operation, while transistorised ignition provides dependable starting and consistent performance.
The engine delivers:
- Maximum output: 4.5kW at 4000rpm
- Recommended output: 4.2kW at 3800rpm
- Maximum torque: 11.2Nm at 2500rpm
Recoil Starting
A straightforward recoil-start system allows the generator to be operated without relying on an electric starter battery.
This simple configuration is particularly useful for occasional backup use, outdoor applications and storage between periods of operation.
Overload Protection
Integrated overload protection helps safeguard the generator and connected equipment if electrical demand exceeds its operating capacity.
Care should still be taken when powering motors, pumps, refrigerators and other appliances with high startup requirements. Their starting demand may be considerably higher than their normal running consumption.
Extended Runtime
The integrated 6-litre petrol tank provides up to approximately 8 hours of operation, depending on the connected load and operating conditions.
Fuel consumption is stated at approximately 0.65 litres per kWh, with an engine consumption rate of approximately 350g/kWh.
Quiet Portable Design
The enclosed inverter-generator design produces a stated noise level of approximately 61dB(A) at 7 metres when operating at quarter load.
At approximately 42kg, the generator remains transportable, while fold-away handles allow it to be moved and stored more conveniently.
Suitable Applications
The Job Site JS3400i is suitable for:
- Emergency household power
- Basic home standby
- Camping and caravanning
