Now that we’ve looked at some of the best rechargeable hand warmers out there, it’s time to learn how you can make the best choice for yourself or your family.

How To Choose The Best Rechargeable Hand Warmer

  • Battery capacity

Battery’s power is measured in mAh and the larger this number is, the more heat your hand warmer can produce. However, you must also keep in mind that a large battery also takes time to charge fully. If you’re in a rush or always on the go, a battery with a capacity of 5200mAh is sufficient. But if you need higher heat settings, 10000mAh batteries will be ideal.

  • Double-sided heating

Some warmers on the market might offer heat on only one side. This might be pretty inconvenient as you may need to turn it over in your palms. With double-sided heating, heat is released around the entire device and it keeps both your palms and fingers warm.

  • Heat settings

Hand warmers can have as low as one heat level and as high as 6. This could also depend on the power of the battery because the larger its capacity, the higher the maximum temperature it offers. This allows you to choose between different levels. If you like a standard temperature range, you can settle for 2 or 3 levels but if you tend to heat or cool easily, get as many settings you prefer. Hand warmers that have a LED display to inform you of the heat level are ideal as they make it easy to switch between settings.

  • Design and shape

There are quite a few shapes and designs out there but you must settle for a hand warmer that feels comfortable to you. Rounded edges with a lightweight body is a suitable option as this device is carried in your pockets or gloves. Models with bigger batteries might be bulky and might feel heavy when you hold them. You can choose from rectangular shapes or those shaped like a computer mouse. Look for an anti-slip grip and devices coated with silicone oil as the hand warmer might be damaged if it falls.

  • Multiple functions

If you like to reap many benefits from one product, look for hand warmers that come with a flashlight that can be used during emergencies. As these devices are handy when used outdoors during activities like camping or hiking, you can take full advantage of the extra features. Most hand warmers can also be used as power banks that charge your phones and tablets. However, you might have to use this function when the heat feature is not active.
