    All battery adapters are designed and manufactured by Terrafirma Technology and are compatible for use with batteries manufactured by other brands. We are not affiliated with DEWALT®, MILWAUKEE®, RYOBI®, KOBALT®, Porter Cable® and/or any other brands.

    Warning: To use this adapter properly, we recommend using a fuse thats rated about 30% higher than the max current you expect to draw. We also recommend adding a low voltage disconnect circuit or a timer to prevent the battery from dropping past low voltage threshold (which will damage the battery or shorten its life span); (Max battery voltage/4.2)*3.3 = typical low voltage threshold. To protect your device you should convert your voltage using a DCDC converter to match your device's acceptable voltage range. We do not recommend buying our adapters without fully understanding how to use it properly, protect the battery, and the device you intend to power.

    All power adapters designed and assembled in Ohio, USA. Made in heat and chemical resistant material.
