RIDGID 18V to Ryobi 18V Battery Adapter

This adapter lets you power Ryobi 18V ONE+ cordless tools with the RIDGID 18V batteries you already own. Both run at 18V, so the adapter changes the fitting and not the voltage. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. This helps you get the most out of your existing battery system while avoiding the cost of another set of batteries and chargers.

Why choose this adapter

• Your RIDGID 18V battery and Ryobi 18V ONE+ tools run at the same voltage, so the adapter changes the fitting rather than converting anything.
• Injection-moulded ABS, not 3D printed — no layer lines to split under load.
• Solid copper terminals, so less of the current is lost as heat.
• 5 mm² internal wiring, rated for 40A continuous with 80A peak at 18VDC for up to 2 seconds, so a high-draw tool is not held back by the adapter.
• Made for the RIDGID 18V batteries sold at Home Depot, so the fit is the one you already own.
• Covered by a 12-month warranty from the day it arrives.

RIDGID 18V and Ryobi 18V ONE+ compatibility

It works in one direction only: RIDGID batteries powering Ryobi tools. For the opposite pairing, see adapters that run on Ryobi 18V ONE+ batteries.

Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the RIDGID 18V platform and that your tool takes Ryobi 18V ONE+ batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge RIDGID or Ryobi batteries and must never be connected to a charger of any kind. Always take the battery out of the adapter before charging, and charge it on the original charger made for your RIDGID 18V battery.
