Full-range Power Layout for Diversified Demand: The lineup covers rated power from 4.2kW~18kW (max 4.5kW~20kW) with 5 models (M4/M6/M9/M12/M18), matching home backup, RV camping, construction site and commercial emergency power supply scenarios. Engine displacement ranges from 224cc up to 925cc, independently RATO self-developed powertrain delivers stable power output with optimized fuel combustion efficiency.
Dual-frequency & Multi-voltage Global Compatibility: Supports 50Hz/60Hz dual frequency, available with 120V/230V/240V multi-rated voltage, perfectly fits North America, Europe, Southeast Asia and most global grid standards for worldwide market deployment.
Premium Inverter Pure Sine Wave Output: Advanced inverter tech supplies clean pure sine wave electricity, safely powers sensitive electronics (laptops, medical devices, household appliances, precision instruments) without surge damage.
2. Ultra-low Noise & Silent Design (Core Flagship Highlight)
Adopts fully enclosed silent cabinet structure; noise controlled at only 59~62dB @7meters across M4-M9 models, far quieter than conventional open-frame generators. The optimized air duct & muffler system suppresses operating noise greatly, ideal for residential, campsite and noise-restricted working environments.
3. Flexible Starting & User-friendly Operation
Smaller specs (M4/M6/M9: GS5500E-B/GS8500E-B/GS11700E-B): Dual start system: manual pull start + electric key start, flexible for emergency startup when battery runs low.
Large-power variants (M12/M18: GS15600E-B/GS24500E-B): Standard full electric start for effortless one-button ignition.
Equipped with intuitive digital display panel + standardized multi-type AC/DC output sockets, parallel connection port available for users to link 2 units for extra power expansion.
4. Large Fuel Tank & Long Continuous Runtime
Graded large-capacity fuel tank from 12.5L to 60L:
M4:12.5L tank → 4.5h continuous runtime under full 100% load
M6:20L tank → 5h full-load working time
M9:27L tank → 5.6h continuous operation
M18:60L large tank → 5h full-load endurance Reduces frequent refueling downtime for all-day outdoor or standby power use.
5. Ergonomic Portable Structure & Durable Build
Mobility Optimization: Integrated foldable pull handle + built-in rubber rolling wheels for M6/M9/M12/M18, easy single-person transport and relocation without heavy lifting; compact body size with tiered dimension design from 580×450×470mm up to 990×780×900mm to balance power and portability.
Weight Rationalization: Net weight spans from 35kg (M4) to 180kg (M18±5kg), high-strength wear-resistant plastic housing protects internal engine and electric components against bump, dust and outdoor harsh weather.
6. Excellent Logistics & Container Loading Efficiency
Optimized body layout improves container utilization: 40HQ loading quantity from 380pcs (M4) down to 78pcs (M18), high container loading rate cuts customers' ocean freight cost per unit for bulk export.
7. RATO Independent R&D Flagship Quality Assurance
Entire series is in-house self-developed flagship product by RATO, mature proprietary engine & inverter core tech with strict production calibration, stable quality, reliable after-sales spare parts supply and long service lifespan compared with generic generators.
