Herbertz Petrol Pocket Hand Warmer

Product Information

Our tester wore these through last year’s frigid Wyoming winter, where temperatures dropped consistently below zero. He wore them primarily while pushing the snowblower to clear snow from his large driveway, noted that even his fingers, which are particularly sensitive after a woodworking accident, remained warm and comfortable. In terms of heating capacities, it’s a dual mode hand warmer and can heat one side of the gadget for 12 hours (mode 2), or both sides for 6 hours (mode 1). It can also deliver 2 full charges for most smartphones and has bright red and white LED flashlights with 5 modes in total: red light only, white light only, red light blinking, white light blinking, and an SOS light.

Make sure Hand Warmer is cool to touch. Remove Hand Warmer lid, then remove the catalytic burner unit from base until by holding it lengthwise (upright with Zippo logo). Burner unit may have a tight fit. Our experience with the Zippo Heat Bank 9 puts us fully on board with rechargeable warmers. We experienced consistent heat for the longest time from the power bank, and while it isn’t cheap, it doubles as a battery charger for your phone, ensuring it will be used year-round While the Zippo Hand Warmer emits an impressive amount of heat, I found it fairly complicated to use during testing, especially compared to the simplicity of the Ocoopa. First off, this hand warmer can’t be used straight out of the box—you need to first acquire lighter fuel, which is sold separately. The instructions for the Zippo warn you not to spill any of the lighter fluid while filling the tiny plastic filling cup, which sort of resembles a watering can, and then tipping the lighter fluid into the hand warmer itself. I was unsuccesful in that and spilled lighter fuel both times. The instructions then further state the hand warmer should be allowed to stand upright for at least two minutes prior to use, and that it is important that the warmer not lay flat before being ignited; however, the design of this hand warmer is not conducive to standing upright. While battery-powered warmers are great, they tend to be less effective in cold conditions. It’s important to note maximum temperatures are generally only achievable for most hand warmers in relatively moderate conditions.Once the Zippo 12-Hour Hand Warmer is ignited there is no way to stop the heating action. If necessary, place the Hand Warmer in the bag and place on a fireproof surface until the fuel is exhausted and the Hand Warmer is cool to the touch. Does the Hand Warmer need oxygen to operate? Hand warmers in this category run on liquid fuel and require a flame to start flameless combustion. Because these warmers generate heat via combustion, they never need to be charged and work well even in very cold temps. Though catalytic warmers provide a consistent heat source for longer periods of time, they can be messy and somewhat complicated to fill. This really only applies to the Zippo 12-hour Hand Warmer.

HotSnapz reusable hand warmers come in a variety of different sizes, however, we’ve chosen the 4-inch round warmers here to ensure they’ll fit cosily in your winter hiking gloves. In theory, the number of times you can reuse these is infinite, however, given the hardiness of outdoor activities, most people get between 200 to 300 uses out of these. The maximum temperatures of the hand warmers I tested varied considerably, from a so-so high of 108 degrees up to a scorching 189 degrees. Why Trust Outdoor Life?While at first glance the Ignik Hand Warmer looked like the other disposable single-use hand warmers in my test, its contents can be composted, either in your home composting bin or your city’s composting program.Four of the ingredients in the hand warmer—vermiculite, activated carbon, cellulose, and salt—will break down anywhere between a couple of weeks and a couple of months depending on your home composting setup, while the fifth ingredient, iron shavings, provide essential minerals to the soil. It’s not entirely waterproof but should heat up in just 10 seconds, and can be turned on and off as you please. Ideal for a day’s hike, there’s also a USB charging port, though it can’t be used at the same time as the heater.
