Portable gasoline generator – 2.5-2.8 kW, 230V, 50Hz, 1 phase, 6.5 HP, 2 x Schuko sockets
Portable gasoline generator designed for autonomous 230V power supply in locations where there is no permanent electrical grid or where temporary backup power is required. The generator has 2.5-2.8 kW power, single-phase 230V / 50Hz output, 6.5 HP 168F-1 engine, manual recoil start and two European-type socket outlets.
Main idea:
This generator is intended as a temporary or backup single-phase 230V power source when electric tools, lighting, small household equipment, construction equipment or other devices need to be connected, provided that the total load does not exceed the permitted generator power.Output power

The gasoline engine mechanically drives the generator alternator, which produces single-phase 230V / 50Hz electrical energy. Two electrical devices can be connected to the generator through the built-in European-type socket outlets, without exceeding the total permitted load.
The generator is started manually using a pull recoil starter. Thanks to its compact design, it can be used on construction sites, homesteads, garages, workshops, outdoor events or as a temporary power source in emergency situations.
When is it worth choosing a 2.5-2.8 kW generator?
A generator of this power is suitable for small and medium loads: lighting, small electric tools, chargers, water pumps, refrigerators, workshop equipment or backup power supply for household appliances. Before connecting devices, their starting currents must be evaluated.Technical parameters

- Autonomous power supply – operates without a permanent electrical grid.
- Single-phase 230V output – suitable for many household and technical devices.
- 2 x EU sockets – two devices can be connected after evaluating the total load.
- 2.5-2.8 kW power – for smaller electric tools and backup power supply.
- 6.5 HP gasoline engine – for autonomous generator operation.
- Manual starter – simple mechanical starting system.
- Compact design – convenient for temporary work and mobile power supply.
Where is it used?
- Construction sites – for powering electric tools, lighting and smaller equipment.
- Garages and workshops – when there is no permanent electrical connection or a backup source is required.
- Homesteads and farms – for pumps, lighting, chargers and other devices.
- Outdoor events – for powering lighting, sound equipment or small devices.
- Emergency power situations – when the grid power supply is interrupted.
- Mobile workplaces – for installation, repair and maintenance work.
Practical usage example
For example, on a construction site, the generator is placed in a stable, dry and well-ventilated location. Work lights, battery tool chargers, a drill or other single-phase electrical devices can be connected to it.
When connecting several devices, it is important to add up their total power and leave a power reserve. Motors, pumps, compressors or some electric tools may briefly consume several times more current during start-up than during normal operation.
Usage according to need
For a builder and installer: a suitable solution for powering electric tools, work lights, chargers and other mobile equipment at sites without a permanent electrical connection.
For an agricultural specialist: can be used as backup power for water pumps, lighting, feed or small technical equipment.
For a homestead owner: useful during power outages or in places without permanent electricity supply – in a garage, workshop, garden or temporary construction area.
For an event organiser: can be used for small outdoor lighting, sales points, technical equipment or other smaller loads, when there is a sufficiently safe and properly ventilated working area.
Advantages
- Autonomous 230V power source – no permanent electrical grid is required.
- 2.5-2.8 kW output power – suitable for many small and medium loads.
- 2 x EU sockets – convenient connection of several devices.
- 6.5 HP engine – for generator operation and power reserve.
- Manual start – simple mechanical system.
- Single-phase 230V / 50Hz output – compatible with many standard devices.
- Compact design – suitable for mobile and temporary power supply use.
Disadvantages / limitations
- No wheels and no transport handle – moving it may require more physical effort.
- Manual start – no electric starter.
- Single-phase generator – not suitable for three-phase 400V equipment.
- Requires gasoline – operating time depends on the fuel tank capacity and load.
- Not suitable for use indoors – gasoline engine exhaust fumes are dangerous.
- Generator power must be evaluated with a reserve – especially when connecting pumps, compressors or other devices with higher starting current.
Safety and usage notes
A gasoline generator must be used only outdoors or in a very well-ventilated area. Exhaust gases, especially carbon monoxide, are dangerous to health, therefore the generator must not be used in living spaces, garages, basements or other enclosed areas.
- Use the generator only outdoors or in an open, well-ventilated area.
- Do not store or refill fuel near a running or hot generator.
- Before connecting equipment, check its power and starting current.
- Do not exceed the permitted generator load.
- Place the generator on a stable, dry and level surface.
- Protect the generator from direct rain and water ingress.
- Before maintenance or refuelling, switch off the engine and allow it to cool down.
- Do not connect the generator directly to a building electrical network without a properly selected manual or automatic transfer switch and a connection scheme installed by a qualified electrician.
Quick selection guide
Choose a portable 2.5-2.8 kW gasoline generator when you need a single-phase 230V power source for smaller tools, lighting, chargers, pumps or backup power supply. It is suitable for mobile use, but before choosing it, the total power of all connected devices must be evaluated.

- a backup power source in a homestead or farm;
- to power work lights, small tools or chargers;
- a single-phase generator for loads up to approximately 2.5-2.8 kW;
- a generator without wheels and transport handle.
Check before ordering:- whether a single-phase 230V generator is required, not a three-phase 400V generator;
- whether the total power of the connected devices will not exceed the generator power;
- whether the devices do not have a high starting current;
- whether wheels or a transport handle are required;
- whether the generator will be used only in a safe and well-ventilated location.
Important reminder:
The stated 2.5-2.8 kW power may refer to the rated and maximum generator power. Before connecting sensitive or higher-power equipment, it is necessary to check the exact generator rating plate data and leave a sufficient power reserve.FAQ – frequently asked questions
What power devices can be connected?
Devices whose total power consumption does not exceed the permitted generator power can be connected. It is recommended to leave a reserve, especially if motors, pumps, refrigerators or electric tools are connected.Can a three-phase 400V device be connected?
No. This generator is single-phase and supplies 230V / 50Hz voltage. Three-phase 400V devices require a suitable three-phase generator.Does the generator have an electric starter?
No. According to the provided information, the generator is started manually using a recoil starter.Does the generator have wheels?
No. According to the provided information, the model is supplied without wheels and without a transport handle.Can the generator be used in a garage?
Not in an enclosed garage. Gasoline engine exhaust fumes are dangerous, so the generator must operate only outdoors or in a very well-ventilated, open area.Can the generator be connected to a house electrical network?
It must not be connected directly. A properly selected grid-generator transfer switch and a connection scheme installed by a qualified electrician are required to protect against backfeeding voltage into the electrical grid.Reliable mobile 230V power source for work and backup power supply
