{"product_id":"craftsman-20v-to-masterforce-20v-battery-adapter","title":"Craftsman 20V to Masterforce 20V Battery Adapter","description":"\u003cp\u003eUse your Craftsman 20V batteries on Masterforce 20V cordless tools, without buying into a second battery platform. Voltage is not the obstacle here — both sides are 20V. The socket is, and that is what this solves. The battery side is injection-molded ABS and the tool interface is high-precision 3D-printed ABS for an accurate fit, with pure copper contacts carrying the current. A practical way to extend the value of the Craftsman 20V batteries you already have.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eSKU\u003c\/b\u003e PTA-CRA20-MAS20\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFits this battery\u003c\/b\u003e Craftsman 20V (Lithium-Ion)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBattery voltage\u003c\/b\u003e 20V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRuns these tools\u003c\/b\u003e Masterforce 20V (Lithium-Ion) from Menards\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\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 40A continuous (80A peak at 18VDC for up to 2 seconds)720 Watt continuous at 18V 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 130 g (4.6 oz \/ 0.29 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eColour\u003c\/b\u003e Red, 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 June 19, 2025)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy choose this adapter\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eYour Craftsman 20V battery and Masterforce 20V tools run at the same voltage, so the adapter changes the fitting rather than converting anything.\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 40A continuous with 80A 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\u003eCraftsman 20V and Masterforce 20V compatibility\u003c\/h2\u003e\n\u003cp\u003eIt works in one direction only: Craftsman batteries powering Masterforce tools.
