RIDGID 18V to Ryobi 18V Battery Adapter It cannot charge DeWalt orThis 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.
