3600W Portable Power Station Kompak KPG3600

Kompak KPG3600 portable power station: industrial power without petrol

The Kompak KPG3600 is a 3600W portable power station built for people who work for a living: construction sites, maintenance crews, film sets, street markets and emergency response. It delivers 230V pure sine wave power for high-consumption tools and replaces a traditional battery generator or petrol generator with no noise, no fumes and no refuelling.

With 2304Wh of capacity, NCA 21700 cells with 10C discharge and a weight of 23.8 kg, it combines professional-grade performance with the simplicity of a consumer power station: plug in, press the button and get to work.

High power: 3600W rated and up to 20,000W peak

The KPG3600 provides 3600W of rated power. Based on the manufacturer's real-world tests with loads such as welding machines and air compressors, it reaches up to 20,000W of peak power. It also handles controlled overloads:

• 150% (4000–5400W): more than 500 s.
• 200% (5400–7200W): more than 50 s.
• 250% (7200–9000W): more than 10 s.
• Above 9000W: more than 1 s.

That makes it a real option as a generator for welding, angle grinders, circular saws, electric breakers and compressors, which all need a strong starting surge. No-load consumption is just 30W or less.

A silent alternative to petrol generators

Compared with a petrol generator of the same rated power, the KPG3600 offers:

• Zero noise: a truly silent generator, ideal for night work, indoor jobs, film sets and residential areas.
• Zero emissions: no CO or NOx, suitable for well-ventilated enclosed spaces such as tunnels or workshops.
• No maintenance: no oil, spark plugs or carburettor, and no risk of fuel leaks.
• Lighter: 23.8 kg versus about 42 kg for a comparable traditional generator.
• Better protected: IP54 versus IP23.

Running cost (manufacturer data)

According to Kompak's comparison for 1,000 hours at full load, with electricity at €0.29/kWh and petrol at €1.63/l, the KPG3600's energy cost is around €1,044 versus around €3,421 for a 3.6 kW petrol generator (roughly 70% savings), plus about €150 of maintenance avoided. These are manufacturer figures under theoretical conditions: your real savings will depend on usage and your electricity tariff.

High protection: IP54, steel frame and outdoor work

Resistant to dust and water splashes with IP54 protection, the KPG3600 is designed for construction sites, quarries and outdoor use:

• Laser welding and ring seals for waterproofing.
• V-shaped steel tube frame and steel sheet casing that protect against knocks and drops.
• SGCC corrosion-resistant coating tested for 72 h in salt spray, a relevant detail in coastal environments such as the Canary Islands.
• Natural cooling with internal circulation, with no noisy fans.
• BMS protections: overcharge, over-discharge, overcurrent, over-temperature, short-circuit and overvoltage.

Operating temperature: discharge from -15 °C to 55 °C and charge from 5 °C to 40 °C. It complies with UN 38.3, IEC 62619 and IEC 62477.

Fast charging: ready in 2.3 hours

It charges to 100% in 2.3 hours and to 90% in 1.8 hours from a standard 230V socket (input up to 1300W). Kompak states it charges faster than other stations in its class (2.3 h versus 2.5–3 h), with a 97% AC-BMS charging efficiency. A lunch break is enough to have it nearly full again.

Light, portable and easy to use

At 23.8 kg and 494 × 502 × 198 mm, one person can load and unload it from a vehicle using its handle frame. The front panel guides use in four steps: connect the cable to the AC socket, press the power button, check the socket indicator light and start working. A 10-level indicator light shows the remaining charge.

Expandable capacity up to 6912Wh

If you need more runtime, you can connect up to 3 units in parallel for a total capacity of 6912Wh. It is a flexible way to scale from a basic setup to a solution for long working days, without buying a larger machine.

How long does the battery last? Estimated runtime

Our own estimate based on 2304Wh and roughly 90% efficiency; real runtime varies with the equipment and its duty cycle.

• 500W load: about 4 hours.
• 1000W: a little over 2 hours.
• 2000W: about 1 hour.
• 3600W (maximum continuous power): about 35 minutes.

For full days with heavy tools, consider expanding in parallel.

Applications for the Kompak KPG3600

• Construction sites: breakers, saws, grinders, compressors.
• Municipal maintenance and field service crews.
• Mining, tunnels and inspection work.
• Emergency and fire services.
• Film and video production: no noise on set.
• Street markets and food stalls.
• Surveying, renovations and interior fit-outs.

KPG3600 versus a consumer power station

Lower-power household stations are not designed for heavy-duty equipment or harsh working conditions. The KPG3600 is: it combines IP54, a steel structure and high peak power for professional use.

Frequently asked questions about the Kompak KPG3600

What tools can I connect to the KPG3600?

Any 230V equipment within its 3600W rated power: grinders, saws, drills, electric breakers, compressors, welders and work lights. According to the manufacturer, it handles starting peaks of up to 20,000W in tests with welders and compressors. Always check the consumption and starting surge of your specific equipment.

Can I use it as a generator for welding?

Kompak reports real tests with welding machines. Even so, usable power depends on the welder model and the current used; check its consumption and, for long jobs, consider expanding in parallel.

Can it be used in the rain?

It has an IP54 rating: protected against dust and water splashes. It is not submersible and not designed for pressure jets.

How long does it take to charge?

2.3 hours to 100% and 1.8 hours to 90% from a 230V socket.

Can the capacity be expanded?

Yes, up to 3 units in parallel, for a total capacity of 6912Wh.

Can I charge it with solar panels?

The spec sheet lists 230Vac mains input. Direct solar input is not specified, so it is designed to be charged from the electrical grid.

Is it better than a petrol generator?

For working with no noise, no emissions and no maintenance, yes. A petrol generator keeps the advantage in continuous runtime if you keep refuelling; the KPG3600 stands out for silence, cleanliness, weight, protection and cost per hour.

Do you ship to the Canary Islands?

Yes. Delivery in 10-20 days with shipping included at bateriascanarias.es.
