This document provides operating instructions for the Ryobi RYi1030A (1,000W) and RYi120A (120W) power inverters. To turn the inverter on, press and hold the power button for 1.5 seconds. The LED will light up green when ready. Always ensure the inverter is turned off before connecting or disconnecting power sources or devices.
Product overview
These power inverters convert low-voltage DC electricity (from an 18V battery or 12V auto outlet) into 120V AC household power. They are designed for charging and operating USB-powered devices, lighting, small appliances, and tools within the rated wattage capacity.
Safety instructions
- Do not use with life support devices or medical equipment.
- Do not hard-wire this unit into a circuit or AC distribution circuit.
- Do not block air vents; the unit will automatically shut off if overheated.
- Do not use in enclosed areas with automotive lead-acid batteries.
- Do not expose to rain or damp locations.
- Use only the power cord provided and batteries/chargers listed in the tool correlation supplement.
Installation and mounting
The RYi1030A model includes mounting brackets for stable placement. To install, insert the tabs into the slot and rotate 90 degrees. The unit can be mounted horizontally or vertically.

Operation



Connecting to an 18V battery
With the inverter turned off, slide the battery pack into the inverter adaptor until it is secured. Ensure the battery is locked in place before operation.
Connecting to a 12V auto accessory outlet
Insert the connector cord plug into the receptacle on the rear of the inverter, then plug the 12V DC plug into the vehicle's accessory outlet. Note that some vehicles require the ignition to be turned on to supply power to the accessory outlet.
Using car battery clamps (RYi1030A only)
Connect the red cable to the positive (+) terminal first, then the black cable to the negative (-) terminal. Ensure all connections are tight before connecting to the inverter.
Maintenance
Always replace the fuse with a 12 Amp fast-blow glass fuse. Never use a higher-rated fuse. To replace: ensure the unit is off, disconnect all devices, unscrew the fuse cover on the 12V plug, remove the fuse cap, replace the blown fuse, and reinstall the cap and cover securely.
Troubleshooting
The LED power button serves as an indicator for status and faults:
- Blinking red then off: Overload. Disconnect the device, check battery charge, and restart.
- Solid red: Overheated. Allow the unit to cool until the LED turns green.
- Flashing yellow: Battery pack needs to be recharged.
