    Keeps my coffee perfect all morning

    I’ve been using this Ember tumbler every day for work and it’s awesome. My coffee stays hot for hours without that burnt taste you get from reheating. The setup was super easy, and it connects to my phone so I can pick the exact temp I like. The design feels solid and looks really nice on my desk. I usually charge it once a day and it lasts through my whole shift. The lid seals well, so I can toss it in my bag without worrying about spills. It’s definitely on the pricey side, but if you drink coffee slowly or get distracted during the day, it’s totally worth it. Once you try it, you won’t want to go back to a regular mug.

    fits in my car cup holder well enough

    Ember: Travel Mug vs. Tumbler So I was deciding between the ember travel mug and the ember tumbler and I didn’t find a lot of information to make my decision. I ended up buying both, and like each for different reasons. Ember Travel Mug: -Holds 12oz. Charge lasts about three hours -Has (sold separately) travel charger that plugs into car charger (formerly cigarette lighter). This travel charger is not compatible with the ember tumbler. -interestingly, although the travel charger only works with the travel mug, the travel mug can charge on any Ember coaster interchangeable with the mug or Tumbler chargers -Has display on mug, touch display, that can display temperature, can adjust temperature, and cans display words (nickname you choose in the app). App still functions to change temperature the same way other ember mugs do. -almost too skinny for my cars cup holder -I have the travel mug that does not have the apple location built-in, but keep in mind that the Apple location in the Find My app is similar to an AirTag meeting. It works with Bluetooth within so many feet of the cup rather than GPS so the travel mug can be located in the Find My app as long as it is within Bluetooth range so basically if you’re in the same room as it if you leave it at a coffee shop or something it will NOT show up on your GPS Map in the Find My app Ember Tumbler: -Holds 16oz -Charge lasts about 3 hours -Cannot charge on the Ember travel charger -has a single LED that is not touch responsive the LED acts, the same way as the regular mug, giving a white flashing light when adjusting temperature the solid white light when temperature is reached and various other indicators for charging and out of battery and personalized color that can be chosen in the app -fits securely enough in my car cupholder although it doesn’t go all the way to the bottom it holds securely and does not tip over I drive a somewhat small vehicle Ford C-MAX hybrid 2015 and I feel like I have pretty standard cupholder sizes Overall, I get more use out of the Tumbler because it holds more, but the travel mug is better for trips because of the car charger and I can refill it at gas stations with more coffee or whatever hot liquid I want.

    Good on cold winter mornings

    The Ember mug is a wonderful product that enhances your drinking experience and makes your life easier. It is a perfect gift for yourself or your loved ones who appreciate a hot drink. I only wish that they would make the LED more pronounced, I can hardly ever see it.

    Great Christmas gift

    Purchased this for my wife for Christmas and she loves it! I opted for this one over the mug due to the capacity and the fact that she is always on the go. It may be a little big for some cup holders, but it fits hers in her dodge durango and mine in my gmc sierra. So far very pleased!

    Overall Great Product. The tumblr worked as it was design and kept my tea at the perfect temperature throughout the day. The battery dont last the whole day so if you use it at work def have a charger to charge it when needed.
