This morning, I’m writing about rechargeable hand warmers that I recently purchased because, during the winter, my hands get especially cold due to Raynaud’s syndrome.

Raynaud’s syndrome is a condition that causes blood vessels in the extremities (usually the fingers and toes) to narrow excessively in response to cold temperatures or emotional stress. This narrowing restricts blood flow, leading to symptoms such as numbness, pain, and color changes (white, blue, then red).

After the winter of 2022–23 in Utah, where I scraped, shoveled, and used a snow blower on what felt like 18 feet of snow—but was more like 10 feet the entire winter—my secondary Raynaud’s syndrome worsened. Even temperatures in the low 50s can now cause me pain, numbness, and oddly colored fingertips.

Gloves and mittens help, but I needed more help with my hands and fingertips.

 I used to buy little hand warmer packets that work by opening the package, shaking the packets which starts a chemical reaction. These packets typically contain iron powder, salt, water, and an absorbent material. When the activated carbon the packet is exposed to air, an exothermic oxidation reaction occurs. Oxygen reacts with the iron powder in the presence of salt and water to form iron oxide (rust), which releases heat.

They have, in the past, kept my hands warm—even toasty—when I stuffed them into my gloves. For a couple of hours.

The problem for me is that chemical hand warmers are not reusable, add more trash to landfills, and may increase the demand for mining iron ore and salts. I especially don’t like the single-use aspect of chemical hand warmers.

So, I purchased the reusable, rechargeable hand warmers in the photo above. After being fully charged, they can be used for about 24 hours on the lowest of three settings.

Note: These rechargeable hand warmers only heat the light gray area where the orange lightning bolts are.

The reason these particular hand warmers heat on only one side is that the other side is magnetic, allowing them to be stuck together in a pocket or used as a single unit in a muff or something like a hoodie pocket.

In addition, these hand warmers have a sustainability feature where the carbon emissions from the lifecycle of this product were measured, reduced and offset. That is something I like along with the fact that these hand warmers can be recharged over and over again.

The size of these hand warmers is 3 1/2 inches long, 2 inches wide, and 3/4 inch thick on each side. They fit nicely in my jacket pockets, and I can easily curl my fingers around them to get the most benefit from the heat. They can also be tucked into gloves and mittens.

They have ports for recharging at the top of the warmers and the charging cable is two in one.

Note: I have very small hands, which is why I wanted to give precise measurements.

I’ve tested the three levels of heat and will likely only use the lowest level except on the coldest days. It was nice and toasty.

When my hands aren’t busy photographing the amazing birds and wildlife I see, they will be tucked in my jacket pockets, getting warm!

Right now, here in Arkansas, we are experiencing the first “false spring” of this winter. By that, I mean temps are warmer than normal, and by Sunday and Monday, we expect temps in the low 70s, followed by more days that are warmer than normal.

Winter will be back, though, and I expect I will be getting some colder days to use these hand warmers soon.

I wanted to thank my dear friend Shari Hatch for sending me these wonderfully soft and warm fingertip-less Alpaca gloves. They have really come in handy!

Shari sent them as a thank you for my help with her new blog, Bird-Brain.org. Check her site out! I’ve read the blog posts she has shared so far, and I’m looking forward to her new posts!

I hope my review of these hand warmers will be helpful. Be sure to let me know if you like this review in the comments. I’m thinking about doing another review on a winter jacket I recently bought, too.

Having warm hands and fingers will definitely make my winter bird and wildlife journeys far more pleasant!

Life is good.
