The new Hotronic® Footwarmer m4 powerpack contains four cells for extended heat duration and performs down to minus 9° F.

  • m4 battery pack provides greater overall capacity than earlier packs and does not require full discharge before being recharged
  • Provides four basic heat settings
  • Setting level one heats from 83° to 89° F (28° to 32° C) for 19 to 21 hours
  • Level two heats from 96° to 106° F (36° to 41° C) for seven to nine hours
  • Level three heats from 105° to 116° F (40° to 47° C) for five to 6.5 hours
  • Level four: 135° to 144° F (57° to 62° C) for 2.5 to 3.75 hours
  • Level four can also run continuously for maximum warmth; CAUTION: this mode discharges unit quickly and prolonged duration might cause burns
  • Voltage cut-off system keeps battery pack from reaching inappropriately low voltage levels and further enhances cell longevity
  • Operates with easily read LED indicator lights and simple press-and-hold/press-and-release control buttons
  • Includes a wire clip system with locking plate for stand-alone use or for use with Hotronic's strap and mounting brackets
  • Also enables the use of Hotronic's new sliding strap bracket system (sold separately)
  • m4 powerpack does not include Footwarmer (sold separately)

Manufacturer's stated temperature ranges and durations are based on battery pack at minus 4° F (minus 20° C).
