Description
The Cigma UK 4KVA Gasoline Silent Inverter Generator (Model: KM4000I-K5) is a highly efficient, portable power solution designed for premium power backup. Unlike traditional open-frame builders’ generators, this unit combines an enclosed acoustic soundproof canopy with advanced inverter circuitry, making it ideal for residential areas, RV camping, outdoor events, and commercial mobile workstations.
The key features and specifications for this model include:
Advanced Inverter Technology
-
Pure Sine Wave Output: It produces clean, highly stable single-phase power with negligible total harmonic distortion (THD). This exact grid-quality voltage mirrors household wall outlets, making it entirely safe for sensitive microchip-controlled electronics (such as laptops, smartphones, flat-screen TVs, and modern inverter refrigerators).
-
Integrated USB Charging Ports: The control panel includes dedicated 5V DC USB ports. This allows you to plug mobile devices, power banks, and tablets directly into the generator without needing a bulky 3-pin adapter brick.
-
Smart Eco-Mode Functionality: Features an intelligent throttle control system that automatically scales engine RPM up or down to match the exact load demanded by connected appliances. When running lighter electronics, the engine drops to a lower speed, significantly conserving fuel and maximizing total runtime.
Quiet Operation & Enclosure Design
-
Ultra-Silent Housing: Built inside a fully enclosed, heavy-duty insulated composite plastic shell that dramatically deadens engine vibration and mechanical noise. It operates at an incredibly quiet range of approximately 60 to 65 dB at 7 meters, enabling conversational comfort close to the unit.
-
Manual Recoil Start: Relies on a highly dependable, smooth-pull manual recoil starter system. Free from the complications of dead starter batteries or key ignition wire faults, it ensures quick engine turnaround on the first pull.
Performance & Engine Capabilities
-
Robust 4-Stroke OHV Engine: Powered by a fuel-efficient, air-cooled 149cc (KM165F) overhead valve single-cylinder engine that runs smoothly on standard unleaded petrol.
-
4.0 KVA Surge Capacity: Boasts a peak/maximum output rating of 4.0 KVA (approx. 3.6 kW), with a highly reliable continuous running load capacity of 3.0 kW to 3.5 kW to easily sustain multiple appliances simultaneously.

Smart Safeguards & Indicators
-
Low-Oil Automatic Shutdown: Integrated safety floats instantly cut off engine ignition if the internal oil drops below critical operational thresholds, preventing terminal engine seize-ups.
-
Electronic Overload Protection: Features an internal circuit breaker and diagnostic LED indicators that turn on if output limits are crossed, temporarily clipping power delivery without damaging the internal inverter module.
-
