Hayins Temperature Control Smart Mug, Self Heating Coffee Mug LED Display,(12oz, Black)

This coffee mug is amazing.
I recently tried this cordless heated mug and found it to be a game-changer. The built-in heating element maintains drink temperature for hours, and I love the on-mug controls. While the capacity could be larger, the design is comfortable. Key points to remember: it's not microwave or dishwasher ，it's great for keeping drinks hot consistently. Overall, it's a solid choice if you prioritize temperature control, but be sure to read the care instructions.

This mug is awesome! I love that it is cordless, the mug itself keeps the drink hot and I dont need the coaster to heat the drink. The heating element is inside the mug. I wish the mug had a bigger capacity. The handle is comfortable. I like that the temperature is controlled on the device itself and I can see the amount of charge

As someone who usually zaps my coffee several times to keep it hot enough..........................
As someone who usually zaps my coffee several times to keep it hot enough, this mug is the perfect solution. Just remember you do NOT put this mug in the microwave!! Charge the mug, set the temp and it will stay very warm for hours. The controls on the front of the mug are much better than other name brand mugs with controls on the bottom. The instructions are sparse but definitely should be read before first use. I ordered the large size and it is generous and still keeps the coffee hot, especially if you use the included plastic lid. The full mug will feel heavy due to the battery bottom. Great heated mug, just remember NO microwave and NO dishwasher use.

The mug is perfect,
This is actually the second coffee mug from this same company I have. I loved the first cup so much that I knew I wanted another one for the job. I'm happy to report this works just like my other one. The main difference is that the charging base is no longer connected via USB-C. Now they switched over to a barrel plug, and also don't have a wireless charging area for a second device. Maybe that is another model, but I was surprised when I noticed the slight different. The mug is perfect, and feels great in the hand. This works by keeping your coffee warm while you take your time in drinking it. Given that I take a while to drink my coffee, this is perfect for me since it'll keep it nice and hot throughout the day. For me, the battery will last me about 3 days, but I will admit I tend to need it to heat up my drink for several hours, so your mileage may vary.
