【Inverter Generator】 Lightweight yet high power! The reassurance of being able to obtain "electricity" anytime, anywhere
From outdoor activities to emergency situations, having an inverter generator that can produce power is comforting. With a lightweight & high-output model, it's easy to store even at home!
An inverter generator that is useful from outdoor activities to disaster prevention

When camping with a tent for multiple nights, relying solely on the car's cigarette socket raises concerns. It would be nice to have an inverter generator, but issues like "it's heavy and hard to carry" and "it's difficult for beginners to operate" are common. That's where the inverter generators "JM3800iS" and "JM2400iS" come in.
Both models feature a lightweight and compact design compared to typical generators of the same class. Furthermore, the "JM3800iS" is equipped with a multi-switch for smooth startup. It seems to be a reliable choice for a wide range of situations, from camping and car sleeping to mobile sales and disaster preparedness.

Easy to carry, ultra-lightweight!

The "JM2400iS" weighs about 19kg, while the "JM3800iS" is around 24kg, making them lighter and more compact compared to typical generators in the same class. They are easy to transport for outdoor work and activities, and storage is simple as well. With a space-saving design and lightweight build, loading and transporting them in a car is effortless.
Multiple devices can be used simultaneously.

The JM2400iS is more compact than typical beginner models, but has an output specification that is about 400W higher. It can supply power up to 2.0kW from a single outlet, and can support a total of up to 2.2kW across two outlets. The JM3800iS can supply power with a rated output of 3500W and a maximum output of 3800W. It features dual outlets compliant with NEMA standards and a 30A outlet, designed to operate multiple appliances and power tools simultaneously.
Both models can be smoothly started with a recoil starter system. The JM3800iS is equipped with a multi-switch, eliminating the need to operate a choke knob.

The JM2400iS can be used continuously for about 3.5 hours at rated load and approximately 8 hours of continuous operation at light load with the load reduced to 1/4. The JM3800iS can be used continuously for about 2.5 hours at rated load, and approximately 6 hours at 1/4 load.
Additionally, both models support parallel connection. The JM2400iS has a maximum output of 4180W, while the JM3800iS can reach up to 6300W. This makes it suitable for occasions requiring high-capacity power, such as using electric kettles or cooking equipment during car camping or outdoor activities.

Quiet and eco-friendly design

The operating noise of the JM2400iS is about 56dB, and the JM3800iS is about 59dB, offering top-level quiet performance among similar products.
Despite their high output, they effectively suppress noise, making them usable in quiet environments such as campsites or residential areas. The indicator allows for easy visibility of the operating mode, enabling efficient operation management, so they can be used safely even for long periods.
