vsitoo Temperature Control Heated Coffee Mug with Lid, Smart Self Heating Travel Mug 15 Oz, App-Controlled Heated Coffee Mug with 4-10 Hour Battery Life, 3 Custom Heat Settings (Copper)

I like the smog and the really cool thing is the fact that they include a car charger with it as well. Just know that the car charger is a little difficult to use because even though they did notch out a spot in the bottom on the mug for the cord to run through it's still just a little tough to pop the charger on and off out of your cupholder as you're driving the cover of the mug doesn't stay up. It seems to wanna fall down when you're drinking. Other than that, it's a really cool product has a decent battery life and the fact that it holds a good amount of coffee is a major plus. I got mine in the black color and it looks very nice. Five stars
