Power passes straight through: Stanley FATMAX V20 and Mastercraft 20V (PWRPOD \/ Blue) share the same 20V rating. 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. It removes the need to keep separate batteries for different platforms, which saves money and simplifies the workflow.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eSKU\u003c\/b\u003e PTA-STAV20-MCT20\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFits this battery\u003c\/b\u003e Stanley FATMAX V20 (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 Mastercraft 20V (PWRPOD \/ Blue) (Lithium-Ion) from Canadian Tire\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 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 21, 2026)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy choose this adapter\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eYour Stanley FATMAX V20 battery and Mastercraft 20V (PWRPOD \/ Blue) 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\u003eStanley FATMAX V20 and Mastercraft 20V (PWRPOD \/ Blue) compatibility\u003c\/h2\u003e\n\u003cp\u003eIt works in one direction only: Stanley batteries powering Mastercraft tools.
