Equipped with a 166F four-stroke air-cooled engine and a displacement of 157cc, it delivers a rated power of 3500W and a peak power of 4000W, supporting dual voltage output (110V/220V) and dual frequency (50/60Hz). Featuring pure sine wave technology (THD <3%), along with dual-start modes (electric and manual), it provides stable and clean power while operating at a low noise level of just 68dB. With its 6.5L fuel tank, it can sustain continuous operation for 6.7 hours, making it an ideal choice that balances performance and portability.

Specification

Product Advantages  

1. Pure sine wave output ensures safer electricity usage, with THD <3%, providing stable voltage without fluctuations. It safely powers sensitive equipment such as computers, precision instruments, and household appliances, preventing damage caused by unstable currents.  

2. Low-noise operation for a quiet experience, with noise levels as low as 68dB (7m/rated power). Equipped with a soundproof casing and noise reduction system, it operates quietly without disturbing others, making it ideal for noise-sensitive scenarios like camping or emergency use in residential areas.

 

3. High fuel efficiency for extended runtime. Variable frequency technology automatically adjusts engine speed—lower load results in lower fuel consumption. A 6.5L large fuel tank allows continuous operation for 6.7 hours at 75% load, reducing the hassle of frequent refueling.  

4. Lightweight design for portability and ease of use. Weighing only 26kg, it features built-in wheels and a retractable handle, allowing easy movement by a single person. Compact dimensions (587×373×516mm) facilitate storage and transportation, lowering warehousing and logistics costs.  

5. Intelligent protection for reliability and safety. The built-in smart control system includes multiple protection functions such as overload, overvoltage, undervoltage, and low fuel levels, ensuring stable operation. With dual electric and manual start modes, it guarantees quick activation even in extreme conditions.

Applications

1. Outdoor Camping/RV Travel: Provides stable power for RV air conditioning, lighting, kitchen appliances, creating a comfortable outdoor lifestyle.

2. Family Emergency Backup Power: Copes with power outages, natural disasters, and other emergencies, ensuring the normal operation of refrigerators, lighting, and communication equipment.

3. Small Business Scenarios: Power core for mobile stalls and outdoor markets, supporting cash registers, refrigerators, and other equipment.

4. Outdoor Work Construction: Supplies clean power for electric tools and measuring instruments, suitable for decoration, repair, and other scenarios.
