Reusable Hand Warmers: How They Work, and Which Ones We Suggest

Reusable Hand Warmers

Reusable hand warmers are getting some deserved buzz. Are they better than the old, one-use kind?

When we're outside in the cold, most of us to prevent heat from leaving our feet, head, chest and hands.

There's something about feeling cold in those areas that makes low temperatures the bane of my existence. It's especially true for my hands. If you see me asking people to "Feel how cold my hands are!" just know that I'm probably ready to go back inside.

Thankfully, someone eventually got tired of me complaining about my cold hands and bought me reusable hand warmers. I've loved them ever since.

Reusable hand warmers are perfect for hunters, hikers, ice anglers, or anyone that's outside on a cold day.

These hand warmers provide hours of heat and will keep your hands nice and toasty to tough it out through the fall and winter months.

How Do Reusable Hand Warmers Work?

Many use an internal metal disc for activation. Once you snap the disc, sodium acetate releases instant heat.

HotSnapZ warmers, for example, are a sodium acetate hand warmer. They contain water, the small metal disc and sodium acetate, a food safe ingredient in salt.

The sodium acetate is dissolved in the water when it's first boiled, and it remains dissolved as a supersaturated solution. Pressing the metal disc releases the compound, along with the energy it took to store it, which exits as heat.

This process is infinitely reusable, and most rechargeable hand warmers that don't use a battery operate this way.

How Long Do Reusable Hand Warmers Last?

Knowing how long a set of reusable hand warmers will last depends on a few factors.

Most reusable round heat packs will only last an hour before they need to charge again in boiling water. Some hand warmers that run on rechargeable batteries can last up to eight hours with a full charge.

That's the general range we found among the different claims, meaning you'll want to pay attention to the longevity of the hand warmers you go with before purchasing.

Here are some examples of what you can find and procure easily with a few quick online searches.

1. Hot to Go Reusable Heat Packs

I'm definitely a fan of these OCOOPA rechargeable hand warmers. You can use the port to also charge your phone! These are great stocking stuffers, because there's still plenty of cold winter nights after Christmas.

If you're not sure which ones to go with, consider how long you'll need it. For short commutes, I'd go with HotSnapZ or Hot to Go. For longer outdoor activities I'd go with a rechargeable warmer like Zippo.

Although, HotHands hand warmers are a bestseller among hand warmers. They aren't reusable, but you can buy a a 40-pack of disposable hand warmers on Amazon from HeatMax.

Do your toes also suffer in cold weather? Toe warmers and foot warmers are also available, and yes, they'll fit in your hunting boots. As an added bonus, if you really want to keep your feet toasty, you'll love heated socks.
