I just got this spectacular hand warmer from Amazon – It’s the EnergyFlux Slim by Human Creations. It plugs into a usb/mini usb to charge (or a wall plug like your cell phone), has two heat settings, and lasts 4-6 hours on a charge.
I live in Montana, have suffered from primary Raynaud’s for over 15 years. I used to post on this forum a lot, but under a different name that wouldn’t work anymore. Anyway – here’s the deal with this hand warmer vs others:
It’s easy to charge, and consistent. I’m using it to walk to the grocery store, go out and start the car, walk around town, and for short ski trips. You can turn it on and off, so the 4-6 hours of heat can be split up when you need it.
I still use disposable heat packs for longer skis, for my toes, etc. But this is a great in-town/short trip solution.
The heater also doubles as an emergency cell phone charger, if you want to give up some of your heating energy for that….
I’ve been using it for a couple weeks now – I have chilblains on three fingers and they are so much easier to manage when my hand is warm all the time. Right now I only have one (the heaters are sold one at a time, and are pricey ($38ish I think, each), but I don’t want a second, one is great to switch back and forth.
They are too big to fit in a glove, but it fits in a mitten, which is what I imagine most people use anyway. In a mitten, for those of you who ski, it’s a bit tricky to figure out how to position it so you can still hold a ski pole, but I figured it out. However, like I said, I still use those malleable disposable ones for long skis (I’ve tried others, like the reusable boil hand warmers, those are terrible, don’t last long enough to walk around the block).
So that’s my new favorite product, so great that I wanted to share! Any questions just let me know.
UPDATE: I used the hand warmer last night to go out and pick up dinner, then I forgot about it and accidentally left it on low in my mitten all night and all morning long, 17 hours. It was still on, with one battery light left.
