{"product_id":"greenworks-40v-to-dewalt-20v-battery-adapter","title":"Greenworks 40V to DeWalt 20V Battery Adapter","description":"\u003cp\u003eUse your Greenworks 40V batteries on DeWalt 20V MAX cordless tools, without buying into a second battery platform. Your Greenworks 40V battery is 40V and a DeWalt 20V MAX tool expects 20V. 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. This helps you get the most out of your existing battery system while avoiding the cost of another set of batteries and chargers.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eSKU\u003c\/b\u003e PTA-GRE40-DWM20\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFits this battery\u003c\/b\u003e Greenworks 40V (Lithium-Ion)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBattery voltage\u003c\/b\u003e 40V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRuns these tools\u003c\/b\u003e DeWalt 20V MAX (Lithium-Ion)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTool voltage\u003c\/b\u003e 20V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHousing\u003c\/b\u003e ABS (Injected)\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 60A continuous (100A peak at 18VDC for up to 2 seconds)1080 Watt continuous at 18V nominal\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eInternal wiring\u003c\/b\u003e 6 mm²\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWeight\u003c\/b\u003e 164 g (5.8 oz \/ 0.36 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eColour\u003c\/b\u003e Black\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 9, 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\u003e6 mm² internal wiring, rated for 60A continuous with 100A 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\u003eGreenworks 40V and DeWalt 20V MAX compatibility\u003c\/h2\u003e\n\u003cp\u003eIt works in one direction only: Greenworks batteries powering DeWalt tools.
