12000mAh Hand Warmers rechargeable & Power Bank 2in1 Battery with charge cable USB Electric Hand Warmer Reusable Portable hot hands Heater Pocket Warmer Handwarmer for Winter outwork Camping Fishing Golf

Gave this to my wife as a gift because her hands are always cold. Poor little thing! She started using it immediately as it was already charged up when she received it. It really works good, and she couldn't be happier. She even took it to work to use, as the office she works in is often cold. She showed it off to her coworkers, and several of them said they were going to get one themselves. One even ordered it on the spot! Her sister ordered one too, and is very pleased with hers. They stay charged a good long time and provide 3 levels of heat. Of course she usually keeps hers on low, so it will last as long as possible. Charges up fast too. All in all it is well worth the little it costs.

My reason for purchasing this electronic hand warmer is because I had too many occasions of frustration where I would tear open a regular hand warmer and then wait up to 20 minutes to make sure it gets going and also worry about keeping it functioning throughout it's supposed duration. The awesome part of this hand warmer is that it works! It just works! The ability to control the temperature is a pretty unique and handy feature. Not all of us wants a scorching hot potatoe session and everyone is different in their needs for "how hot" it needs to be to be comfortable. I usually keep it in my pack when I'm outdoors and take it out as needed for those occasionally warmth before I get going during the colder seasons. Keep in mind though, if it's really cold outside like under 40 degrees Fahrenheit or 4 degrees Celsius. The hand warmer does take a bit of time to warm up but it's still a lot faster than a regular bag of hand warmer. A big tip is to turn on the pocket warmer to its highest setting and stuff the pocket warmer inside your jacket to get the heat working quicker. The big plus of this electronic hand warmer is its pocketbility and reusability in my opinion. Definitely worth the purchase! It's extra feature of being able to use as a charger in the event that your other electronics device goes out is a big plus.

It works - purchased for my wife. It’s more complicated than similar devices to run and recharge - USB wire provided as well as another built in wire. Complicated instructions - poorly written Chinese translation into English leave me somewhat confused. Heat settings are numbers - but other numbers are confusing - no info about other numbers in instructions. I have an Ocoopa hand warmer. Very easy to recharge and a button to control heat.

Three temperature settings are changed by the push of a button. It heats up instantly and even can be used as a power bank to charge your phone. I liked it so much that I bought a second one to give as a gift.

This works great as a hand warmer & charger. I use it more for a charger. If you have the right kind of charging cable you can charge more than 1 item at a time.

I recently purchased the Electric Hand Warmer and it has quickly become one of my favorite winter accessories. It's small, lightweight, and easy to carry around in my pocket or purse.The hand warmer has a simple and user-friendly design. It has one button that allows me to easily turn it on and off and switch between three different heat settings. It also has an LED light that indicates the current heat setting.The hand warmer has been a lifesaver on cold days. It's able to heat up quickly and provides a consistent and comfortable level of warmth. I've used it while out on walks, at the office, and while watching outdoor sporting events, and it has kept my hands toasty in all of these situations.The hand warmer is also environmentally friendly and energy efficient. It's rechargeable and has a long battery life, so I don't have to worry about constantly replacing batteries.Overall, I'm extremely satisfied with my purchase of the Electric Hand Warmer. It's a practical and convenient way to keep my hands warm in the cold weather, and I would highly recommend it to others.

Bought 2 of these. They do work and I kind of like them.The firm silicone sides are nice. Being able to charge my phone is nice. Charged my S22 from 30-85% in an hour or so. Not fast charging, but pretty decent in a pinch. I don't know if it is mentioned, but both sides do heat up.They do keep your hands warm. The battery life is way off. So much so it is laughable. If this was just one, I would chalk it up to it being a single defective unit. Both of mine, different colors, if it makes a difference, both last about the same.Being advertised at 8-15 hours is laughable. On medium (50c) is just about 5 hours. There is NO WAY low is going to get 15 hours! High is way too hot, so I did not even go there.One thing I noticed, is the temp swings, for example, on Medium (50c) has wildly big temp swings. It just does not stay at 50c. It ramps up to about 55c, then shuts off.. when it gets to 45c, it turns back on and ramps up to 55c over and over again. sitting here with my IR thermometer playing with it.DO NOT Expect consistent temperature output. On Medium, it goes from "Is this thing working" to "OMG way too hot" fast.. over and over again. I observed this on both my warmersThey ARE very effective, no doubt. Was just using them today outside and it was pretty cold. Was nice to have a warm pocket to put my hands in.These are WAY too big to put in your gloves or shoes. It is a bit smaller than a cell phone, and twice as thick. They are chunky.The charging cable for my S22 was TIGHT and only fit one way, so the QC on the cable end is suspect at best, but it did work and did charge my phone with no issue, at a reasonable speed.Overall I do kinda like them. Performed differently than I expected. For the price they are OK.If they were more honest about the laughable specifications on how long the battery lasts, I would give back a star. Still 5 hours on medium should fit the bill for what I need, but is not even in the range of the advertised specs. I wish the temp would stay more consistent

These hand warmers were a hit. I purchased several of these for my family and coworkers as Christmas gifts. Everyone seemed very pleased with them and how durable and long the battery lasts. I would buy again.
