Zippo Reusable Chrome Hand Warmer 40323

this item is a lot better than the ones that you charge up because this one here wants you get it filled with the fluid use your lighter and light it for the 30 seconds to a minute it will stay hot for 11 hours

I'm one of those guys who's always used the disposable chem packs for hand-warming. I've often been curious about these zippo warmer as our son has two that he takes with him skiing and snowboarding. This was pretty straight forward, though the warmer won't stand on it's own, the bottom is as rounded as the top and you're supposed to fill it to the desired level and then leave it standing upright for 2 minutes. Since it can't stand on its own, you're just holding it during that time frame, so it's not hands-free. I also thought it would have some sort of built-in igniter, but it doesn't so you'll need a lighter or as I did, matches. The instructions are simple and clear, I took the housing apart, removed the burner top (catalytic unit) and filled the base using the included white plastic tank. 1/2 full should go 6 hours? I have the unit heating in my pocket as I'm writing this as part of my evaluation and it's still heating and it's been five hours. I had to light it a couple of times before I could really feel it warming up. HOW HOT DOES IT GET?! Funny you should ask, once it was going good, I put it inside the included black bag and then broke out my thermal imaging system. The upper section had the hottest spots (though the bag) at 112 degrees f, and down to 108 degrees. It did spike to 116, but is a pretty constant at 112. Surface contact temperature of the upper metal casing when lit is in the 120's and not comfortable to touch. I'd definitely say adults only, as you "could" get burned with the unit outside of the bag. So, would I recommend it? YES definitely! I'll need another one so I can have one in each front coat pocket this winter. THICKNESS: less than 1/2 inch WIDTH: 3 inches including the bag HEIGHT: 4 and 1/2 inches including the bag. Perfectly Produced for Pockets People Put their Hands In so Pleased!
