{"product_id":"ryobi-18v-to-dewalt-12v-battery-adapter","title":"Ryobi 18V to DeWalt 12V Battery Adapter","description":"\u003cp\u003eUse your Ryobi 18V ONE+ batteries on DeWalt 12V MAX cordless tools, without buying into a second battery platform. Your Ryobi 18V ONE+ battery is 18V and a DeWalt 12V MAX tool expects 12V. The converter holds the output at the tool’s level for as long as the battery lasts. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. One battery platform across more tools means less spent on batteries and less to keep charged.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eSKU\u003c\/b\u003e PTA-RYO18-DWM12\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFits this battery\u003c\/b\u003e Ryobi 18V ONE+ (Lithium-Ion)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBattery voltage\u003c\/b\u003e 18V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRuns these tools\u003c\/b\u003e DeWalt 12V MAX (Lithium-Ion)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTool voltage\u003c\/b\u003e 12V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHousing\u003c\/b\u003e ABS (Injected)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDC-DC converter\u003c\/b\u003e Yes — 18V to 12V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTerminals\u003c\/b\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCurrent rating\u003c\/b\u003e 30A continuous (60A peak at 18VDC for up to 2 seconds)324 Watt continuous at 10.8V nominal\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eInternal wiring\u003c\/b\u003e 5 mm²\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWeight\u003c\/b\u003e 114 g (4.0 oz \/ 0.25 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eColour\u003c\/b\u003e Black, Green\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOperating humidity\u003c\/b\u003e 5–95% RH\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOperating temperature\u003c\/b\u003e -10 °C to 50 °C (14 °F to 122 °F)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUSB port\u003c\/b\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWhat's in the box\u003c\/b\u003e Battery Adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWarranty\u003c\/b\u003e 12 months after the date of delivery\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRevision\u003c\/b\u003e Revision 01 (released on August 21, 2026)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy choose this adapter\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eInjection-moulded ABS, not 3D printed — no layer lines to split under load.\u003c\/li\u003e\n\u003cli\u003eSolid copper terminals, so less of the current is lost as heat.\u003c\/li\u003e\n\u003cli\u003e5 mm² internal wiring, rated for 30A continuous with 60A peak at 18VDC for up to 2 seconds, so a high-draw tool is not held back by the adapter.\u003c\/li\u003e\n\u003cli\u003eCovered by a 12-month warranty from the day it arrives.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eRyobi 18V ONE+ and DeWalt 12V MAX compatibility\u003c\/h2\u003e\n\u003cp\u003eIt works in one direction only: Ryobi batteries powering DeWalt tools.
