SLB Rechargeable Hand Warmers - 5200mAh Portable USB Electric Hand Warmer 2-in-1 Double-Sided Pocket Hand Warmers with Power Bank for Camping

Awesome product. If I knew this existed, I wouldn’t have been spending so much on traditional hand/pocket warmers. The heat in my car sucks, so this helps me stay warm. I also like to take it with me for when I have to do the counts in the walk in freezer and cooler at work. It comes with a lanyard so you can wear it around your neck. Also works as a power bank.

This thing has saved my life so many times.. You'd be surprised how much one little hand warmer in your pocket can do to boost your morale while trudging through the snow. Plus, it's better for the environment than the single-use kind. I've been out several times with friends who at first tease me for it, but then after a few hours are begging me to let them hold the "little heater" for a while. It dies fairly quickly, after a few hours of use, but I always have mine on max so I'm sure it would last a lot longer on the lower setting. Be advised, the high setting gets VERY hot. Probably best not to leave it on unattended, at least not on the high setting.

I’ve been using this everyday since early January and I love it! I charge it each night and use it each day to keep my hands warm. A charge lasts about 4-5 hours. It is also a power bank, but I haven’t used it for that purpose yet

I was using a lighter fluid powered hand warmer for several years. I bought this one to use in a pinch and it became my primary hand warmer. It will give you about four hours of heat when set on low.

Love these & I suffer from cold hands. Will definitely buy another to trade off. I use while writing, outside, etc.You need a 1A charger to charge.

This product is great but it tends to loose battery fast depending on how much you use it. Other then that great product.

Charge is very short lasting but this otherwise is a good product

Great product. Use it on the golf course.
