Reusable Hand Warmer

The only hand-warmer you will ever need

This rechargeable hand warmer from Ultimate Survival Technologies is the perfect alternate heat source that is both environmentally and economically conscious. This hand warmer can provide up to two hours of heat and can be recharged simply by being placed in boiling water. This hand warmer is a no-brainer as it will cut back on needless waste and keep you from spending money on endless hand warmers.

Features & Specifications:
  • Cut back on waste products from disposable hand warmers
  • Can provide up to two hours of heat
  • Recharging is as simple as boiling water
  • Can reach temperatures of 130° in 15 seconds for instant heating
  • Insulate the warmer in other materials to improve the length of the heat production
  • Dimensions
    • Height - 4.1" (104 mm)
    • Width - 3" (76 mm)
    • Depth - 0.8" (20 mm)
  • Weight - 2.3 oz. (65g)

  • Press the metal disc button within the hand-warmer until it clicks, or activates, and causes the liquid to crystallize.
  • Massage and knead the hand warmer until the liquid is completely crystallized.
  • Place the hand-warmer in desired location (if possible wrap the hand warmer in some sort or towel or material to help insulate the heat and provide a longer period of heating).
  • Recharging:
    • Boil a pot of water, then lower temperature to a slow simmer
    • Gently place the hand-warmer in the simmering water
    • Keep the hand-warmer in the boiling water until the crystals dissolve and the liquid inside the hand warmer turns completely clear (this should take approximately 15 minutes)
    • Gently remove the hand-warmer from the water and allow to cool before using again (if the hand-warmer begins to re-crystallize then place it back in the simmering water until the liquid is completely clear)

These Are Great! Unbelievably convenient and cool science
October 13, 2021
I bought five of these and they work perfectly. A rechargeable, non-electronic method of storing up heat. I use them to stand outside in the cold weather on my breaks at work. They last about half an hour. Start out as gel, end up as a hard, salty chrystal. Boil them, and they are ready to work again. They are almost indestructable, and endlessly rechargeable. Everybody who has never seen one is always amazed their first time. They really work!

My girls love these

Bought these for my girls. Priced low enough to give out as gifts. My oldest discovered that she could place them on her dash under the windshield and "recharge" them without boiling. They love them. Sized to put in pockets.
