ThermaCELL Heat Pack Pocket Warmers

Review by Susie; Product provided for review by ThermaCELL Pocket Warmer

My husband and I both struggle with cold feet and hands. When we first saw the ThermaCELL HeatPacks product lineup, smiles instantly came over our faces. As a runner (both road and trail), hiker, and professional photographer, my hands are often the first part that gets cold and they stay cold for a long time. Neither running nor photography lend themselves to heavy weight gloves to insulate my fingers while hiking the mountains here in New England brings about another level of struggle with keeping my hands warm.

When I received the ThermaCELL HeatPack hand warmers for the purpose of this review, I was pleasantly surprised by their small size especially when combined with all of the features they have according to their packaging. The two small warmers are 2.9 inches x 1.6 inches x 0.45 inches size and contain integrated rechargeable Lithium-Ion Polymer batteries. There is one side of the pack that has a red, textured material on it, which is where the heat is dissipated from (all other sides are hard, black plastic).

ThermaCELL certainly jammed a lot of features into such a small and affordable package! But I think my favorite part is just how easily they can be charged. The set comes with a two USB port charging brick with two micro-USB cables to plug into the end of each heating unit. My cell phone takes the same charging cable! That means that I’ll easily be able to recharge them while on the go. The directions even include figures for charging the packs via a computer, which is convenient. Yipee!

My only concern at this stage in the same, as small as they are, is to ensure I have the room within my gloves to wear them while running, hiking, or photographing this lovely world. Neither my running nor photography gloves are dual layers or have gauntlets. Will they manage to stay in my gloves without a strap on my wrist? Will they be ok being in direct contact with my skin? There are certainly a lot of questions I have without getting out the ThermaCELL HeatPack hand warmers.

Stay tuned for the next chapter of my review of the ThermaCELL HeatPack hand warmers to see just how toasty warm they make my hands as the temperatures continue to drop!
