Hand Warmers Rechargeable, Dnaleao 2 Pack 4000mAh Electric Portable Pocket Heater, Heat Therapy Great for Outdoors, Hunting, Golf, Camping, Warm Gifts

As a first time buyer for "Rechargeable Hand Warmers", I did my homework/ spent time reading a majority of reviews on products where an acceptable amount of reviews are available. I mostly avoid products with limited to none Reviews. On this occasion it really payed off!!!$$$!!!To keep it short in comparison this product stood out for good 👍 reviews 👌 given by a good number of random verified buyers.No one had anything bad to say. In the sea of others where the bad reviews ranged from mostly:"does not deliver on the advertised amount of hours it will operate",to complaints about thermostat problems "Inconsistent temperature changes", and problems with battery charger indicators".This unit 😍 passed all the specs of 12 hours on temperature setting #1. I actually clocked my first set as follows: (1-Set/ 2-Units)1-Set in lowest Temperature setting/ 1 red light on display = OVER 12 HOURS ACTIVE AND CONSISTENT HEAT.Unit (A) Was Fully Drained and Auto-Off at about 12.5 Hours.Unit (B) Was Fully Drained and Auto-Off at about 13.5 Hours.So basically "Above and beyond" !!!$!!!$!!$With the Charging on both meeting the advertised time of 12 Hours, with one actually going 12.5 hours and the other hand-piece of the same package set gave out a full 13.5 hours at setting #1 which I used/tolerated comfortably in my gloves, and the pockets of a double breasted pockets shirt, with a cotton Tshirt underneath. It was good for moving in and outdoors in Chicagoland winds in the low 30s Fahrenheit.I also had my doubts about the duration when reading some of the technical specifications in reference to the battery size, after reading other product reviews complaints about short operation life, and with a 5000mA battery.Thinking this one only has 4000mA,????And yet in practice I can now see that it has everything to do with the "Design" of this product, how it outperformed the others with larger battery specs.Since I was so impressed with my overall first purchase, I bought a second pair.Immediately put on trial/ to the test!!! Thinking 🤔 can it be???And in short, "Yup" 🤩👍🤑🤑🤑✌️😎Credit where credit is due.Lasted the exact same. For some reason one piece lasted longer than the other, but both lasted MORE THAN THE ADVERTISED 12 HOURS in setting 1.And About 6.5 to 7.5 hours in (Setting #2) which gets quite 🔥 Hot, and gave me excellent support for sustained movement in Freezing Chicago windchill at 8 degrees Fahrenheit.I am writing this as the Winter in these parts gets started. As of now I have not seen the need to use setting #3 WAY HOT🥵At temperature setting #2 It has to be really cold to comfortably tolerate these thru my pants pockets onto my legs without any added leggings, like jogging pants or long John's/ thermal leggings.At temperature setting #2 these are too hot to hold directly in the hand, or put in your gloves for a sustained period 😳.As handwarmers directly on the skin of your palm, temperature (#1) the lowest setting is perfect/ Comfortably tolerated for sustained periods of time, in your gloves for example for hours at a time, 🥰 and gives me over 12 hours working time.One more point on the battery and Design. BOTH MY UNITS HAVE PROVEN TO PUT OUT MORE THAN 12 HOURS on setting #1 and over 6 Hours on Setting #2 OF Flawless "CONSISTENT HEAT TEMPERATURE" #1)Hot/warming, #2) Hot/Hot, and #3) Hot Way/Hot, Unwavering, evenly, without a glitch.The led display is easy and very easy to use and see in the dark.Temperature settings 1,2,3 in solid red LED.Press and hold the Button until the red light turns on.Then quick press button to toggle between Temperature settings #1= 1 Solid Red light, #2= 2-lights , setting #3= 3-lights.Charging indicator is blinking blue as progress bar 1,2,3. Drained at one blinking light, half charged at 2 blinking lights, Fully charged at 3 Solid Blue Lights (stops blinking).When the unit is drained it will power off.If you click the start button it will power on to red light then flashing blue before powering off to indicate needs Charging.Did I mention how much I love these guys on a personal level and how much piece and comfort they bring, knowing they are portable warmth on the go. Adjustable for indoors, outdoors, and a moving variety of both in Bone Chilling Arctic like Chicagoland Cold.And they work as advertised, as needed No B.S. / Hassle Free 😑.As a last note. Yesterday I accidentally 🙃 dropped one from about waistband high onto hard concrete floor with a dry Thud!!!!Immediately tested it and it started and operated like a charm. Good endurance.This before I took my review pictures 📸 so check em out. Rugged and Road-Worthy little guys.Also the product boxes have turned out to be excellent road cases, for my 2 sets. They fit really snug and have a clear cover inner box and outer shell with the graphics. Fit great in backpack. I even use the white plastic covers, for extra protection.

I bought 3 of these as an early xmas present for myself, my boyfriend, and my mom/step dad. So far I am the only one who has used them, but I like them mostly. They're compact enough to keep in my pocket and they do heat up really quickly! A lot of the reviews said the lowest setting was warm enough - I know I run incredibly cold (I have really bad circulation to my hands) so I keep mine on high heat, but it still doesn't seem to be hot in my hands. It feels more like I'm holding a warm cup of tea or something. It's nice, but I was expecting that kind of warmth on the lowest setting, not the highest.I'm giving it 2 stars for now until I hear from the rest of my family and see what they think, maybe my hands are just too cold for this?But the other thing that was pretty annoying is that none of the packages I bought came with manuals. More of an inconvenience as I tried to figure it out on my own. I ended up just watching a customer's video which was super helpful.UPDATE: So I love these...mostly. I think I just had to use them a few times for the heat to really get going. I can now use them on the lowest setting and they do a pretty nice job of keeping my hands warm. Like a cup of hot whatever after you've let it sit out for like 5 minutes. I will say though, the heat isn't quite consistent, it'll be warm warm warm, then the heat dies off then it'll be warm again. Maybe this is a way for it to not overheat? I notice it when I'm holding them in a clenched hand and moving my hands about - weird, but I'll deal. Would recommend them for sure!

If you're using Hot Hands or other one-time use products and want to switch to a more eco-friendly, sustainable solution, this is not exactly the same but it works. Here are the pros and cons.Pros:- The heating is good for outside use. The high setting is as warm as Hot Hands.- Looks durable for long time use.- I love that it comes with two-headed charger for charging both at the same time.Cons:- The size in the photos can be misleading. They are small. Here it is compared to a small water bottle.- The batteries last only a couple of hours, unlike eight or ten hours of Hot Hands.However, you should expect that from the product info above. Because it's only 4000 mAh, and the resistance wires by nature require a lot of power. Resistance is what gives you heat and the more the heat is, the more electricity it requires. Think of heating a much smaller version of your indoor grill machine with your cell phone. For long-hour use, you should need 15-20K mAh, which is not available yet. We should wait for the future for that.- Takes long to recharge. Again, it's expected inherently but it also depends on your charger. It's like charging a phone. If you're using laptop's USB drive, it will charge forever, because these are designed not to drain your computer. Your best bet is to tuck them into a surge protector with a USB drive or a high Watt charger. Don't use a 5W charger (actually, don't use those for anything), use a 20-40W charger.- Warm only on one side. I thought it had grills on both sides, this one came as a surprise. The heating area is also small. I have small hands, wear gloves for 12-year-old girls and only the part I circled with yellow heats. So, if you have big hands, it won't heat everywhere.Given the product specifications, it's a good and decent product if you know what to expect. If you don't check the specs and expect Hot Hands performance, you'll be disappointed.
