What experts didn't like

Lower quality than mugs like Ember.


Many of us love a hot cup of coffee or tea, but it often cools too quickly, or it’s too hot to drink straight away. There are a number of options available for keeping a mug of coffee or tea at the perfect drinking temperature, including passive heat-retaining mugs and active temperature-controlling mugs.

Heat-retaining mugs are different from temperature-controlling mugs, but often achieve the same goal. The primary difference in effectiveness is how frequently you plan to top off your mug over the course of the day.

If you plan to slowly work on a cup of coffee or tea steadily over the course of a day, you might prefer a temperature-controlling mug, which uses a battery to keep its liquid contents at a steady temperature. This way, you can enjoy your drink at the temperature you like it at, at least as long as the battery holds out.

If you are more likely to drink multiple cups of coffee over the course of the day, you may be just fine with a heat-retaining mug. Each time you refill the mug you will be adding hot liquid again, which will bring the overall temperature up and restore the phase-change material’s store of thermal energy.

Buying Advice

  • A car-charging heated mug is great for traveling, but doesn’t work as well when you’re spending a lot of time at a desk.
  • Heated mugs with charging or power coasters are ideal for work stations you’ll be seated or standing at for long periods, but if you only have one such coaster, you’ll need to bring it with you when you transition between work and home to take advantage of the powered functions of the mug.
  • Longer battery life usually equates with a heavier or bulkier battery. Keep that in mind if you plan to move around with your mug a lot, such as between frequent meetings or coworkers’ desks.
  • Powered mugs will sometimes include a removable inner lining to make washing easier, but will almost always require hand washing.
