This generator is a compact powerhouse, and it's a great option for those looking for a smaller generator. However, the Honda 6500 is also celebrated for its excellent quality and it's able to provide similar specs, at a lower cost.

The Honda Gx390 is a petrol 389cc generator with a rated wattage 7000 and starting wattage of 8750. It's 4-stroke engine, able to run for 3.5 hours, is renowned for its ability to meet high-quality standards. It's perfect for use during power outages at home, or to power you during a camping trip.

In comparison, the Honda 6500 is a industrial, portable inverter generator with a rated wattage of 5500 and a starting wattage of 6500. It's iAVR (Intelligent Automatic Voltage Regulator) Technology allows it to regulate voltage, with a powerful Honda iGX390 commercial grade engine. It's ideal for industrial and construction use, and has been rated #1 by professionals in this field.
