3. Product Features
High Output & Quiet Operation
The SUA1500i provides 1,500 starting watts and 1,200 running watts. With a noise level of only 60dB, it is suitable for environments where quiet operation is desired, such as camping or tailgating.
Powerful & Efficient Engine
Equipped with a 60cc OHV high-performance 4-cycle engine, this generator offers fuel efficiency, reliability, and excellent heat dissipation for long operational life.
Pure Power for Sensitive Electronics
Inverter technology ensures a clean and stable power source with less than 3% Total Harmonic Distortion (THD). This makes it safe for charging sensitive electronics like laptops, smartphones, and operating delicate power tools.
Comprehensive Control Panel
The control panel includes a CO sensor indicator light, data indicator lights, one Duplex 5-20R 20A 120VAC outlet, one 3.6A USB-A port, and one 3.0A USB-C port. It is also parallel capable for increased power output when linked with another compatible unit.
Low Idle Technology & Compact Design
Weighing only 28.5 lbs, the generator is ultra-lightweight for easy transport. Low idle technology allows for an extended run time of 8 hours at 25% load with its 0.7-gallon fuel tank.

4. Setup
4.1 Unpacking and Included Components
Carefully remove the generator and all components from the packaging. Inspect for any shipping damage. If damage is found, contact customer service immediately.

The box typically includes:
