Hand Warmers Rechargeable-Electric Hand Warmers, Max 16 Hrs Warmth Up to 127℉, LED Display & Flashlight, Dual-Side Heating Portable Heater for Golf Hunting Camping for Men Women, Valentine's Day Gifts

It’s the start of another Midwest winter using these here in the United States, and I thought it a good time to write a review because I’m very happy with them. I like having active heating while out in the cold; having something warm to hold is somehow really good for my morale. These are the fourth set of electronic hand warmers I’ve bought, and I feel like I’ve finally found the perfect product. Previous warmers were either too big, or too small. The large ones were great at keeping my hands warm, and lasted a long time, but took up too much space in my pocket, and were kind of heavy. The little ones were of course inadequate in both size and run times. I use these to keep my hands warm while dog walking. I wear a thin glove on my dominant hand to dole out treats and to wield a poop bag. These hit the sweet spot: they are the perfect size for my XL hands to hold, and they last a satisfactory amount of time. A long press on the left-side button turns on the warmer; a short press shows you precisely the battery level, 0% - 100%. It always starts at the lowest level, showing “L1.” Only one side of the warmer is now emitting heat, at its lowest output. A short press on the right-side button raises the output thru four levels to “L4.” A long press on the right-side button switches the warmer to high; both sides now output heat. The LED screen shows “H1,” which amusingly looks like “Hi.” Quick presses off the right-side button cycle you thru H-1/H-2/H-3/H-4 and then back to H-1. I have found that the H-2 setting keeps my hands toasty while walking my canine. Most walks use between 10% to 20% of battery power; plugged into a USB-C cord, they charge up within an hour to be used again. I estimate that on the H-2 setting, which is my usual setting, they will last around ninety minutes, although I am rarely outside with a dog that long. If I am going to be outdoors all day I usually use several chemical hand warmers per pocket. There is a USB port, in case you wanted to use it as a power bank; I have never done so, and would hazard it would deplete quickly if used to power up a phone. There is a light on a corner, but it is pretty weak and not much use. A quick triple press of the left button turns it on or off. Really the only criticism I have is that the hard shell is slippery, and they have slid out of my coat pockets, though they sustained no damage hitting the sidewalk. I’m going to try putting a tough wide rubber band around them to give a bit of grip. So, a great product at a great price: they’ll easily keep your hands warm for most needs, they’re simple to use, and I think they’re the perfect size.

If you want quality 360 hand warmers these are the ones to buy! Heat up quick. Have good charge life even on high. And are very warm.

Pleasantly surprised. Charge quickly, warm up quickly and do run according to advertised times and heat setting. Bought a pair for white elephant gift exchange. Bought a second pair to try for myself. Would buy again and recommend to others as a good purchase.

I bought these specifically to have when I go to football games. I was not disappointed! Having two was a plus because I could share one with the husband. I was ALMOST disappointed for two reasons: 1- I had them on high and they didn't seem to get to the temp listed for quite some time. However, when they did, they were nearly too hot! But, switching to low at that point kept my hands perfect. 2-Only one side actually heats so grasping it meant my palms were warm but fingers cold. Again, this didn't take long to become a non-issue because my gloves heated up and fixed that problem. I put it on the back of my hand for a bit every so often and that helped the gloves stay toasty. So much so, in fact, that it really wasn't a problem sharing one at all. I was also pleased to see that they came not with 2 individual USB charging cords, but one cord with two ends. That was a bonus as my hub was full! The battery lasted the whole football game with some to spare. Overall, I was very pleased with the purchase.

This is exactly what I was looking for. The build quality is beyond what I expected for the price. Digital battery display, USBC charging, battery last a long time, flashlight is a nice bonus.

They are worth the money! Lasts all day and very warm!

They worked well walking 3 miles in 20 degree weather with battery to spare. Also recharged quickly while simultaneously charging both with the split cable.

They work great and hest up quickly. I haven't tried using them as battery packs. Only 3 stars because they work great as hand warmers and charge up fast but the battery life is no where near as advertised. I use them for an 8 hour shift at work and started using 1 then other. 1 will make it about 3/4 of my shift on H2 setting. Also the lanyards broke first day in my pocket from just the rubber bending. Great device if you don't care about the battery usage.
