For hours-long-comfort or bikes with older charging systems, this digitally regulates the amount of power to the garment, allowing you to set (or adjust) your vest or liner's maximum heat, or to the exact balance point where the battery continues to be charged. (Reassuring on dark, cold, wet, miserable nights when you need driving lights, heated clothing, and a gadget or two.) Features a rotary on/off switch with an LED that blinks faster as you turn up the heat. Available in two configurations: Standard is ready to plug-and-play with SAE connectors on a 16 3⁄8"(for connecting to the bike), and a 17 5⁄8" (for connecting to your garment) cord. The Panel Mount is ready for a permanent installation with a 17 3⁄4" SAE cord (for connecting to your garment), a 31 1⁄2" cord (for mounting to your bike), and a 22 1⁄4" battery fuse cord. 1.5"×2.25" ×.75".
