Lukewarm coffee is the only insult I regularly give myself. I get distracted by work and forget my mug until it cools down, only to find my once-beautiful coffee tepid and stale and tragic. The best mug warmers and temperature control mugs offer an elegant and tempting solution: What if my coffee never had a chance to get cold?

But it's a delicate balance between keeping my coffee appropriately warm and roasting the bottom of the cup until the coffee within begins to burn and turn bitter and acidic. Reheating cold coffee makes this bitterness even worse. Only the gentlest of mug warmers will do. I also—no offense to the most tech-forward solutions—don't want to require Wi-Fi and an app to warm my morning Joe. Maybe I also don't want my coffee warmer to be ugly.

Unless you're a terribly specific person, the Ohom Ui 3 Self-Heating Mug ($105) offers the simplest and most pleasant solution. It is a handsome ceramic mug with metal in its base, paired to an induction coffee warmer that could also, if need arises, charge your phone wirelessly. Among budget-conscious options, I like the simplicity of a Cosori Mug Set ($40) that can adjust temperatures to my liking (after only small trial and error).

But if I'm being honest about life, the best way to keep coffee warm is actually a good vacuum-sealed, insulated drinking vessel—which also works while on the go, without batteries. My most common solution is to drop a four-cup batch of coffee into my Fellow Carter Move Mug ($35). My coffee will stay warm for the entire workday and is insulated from oxygen that makes it stale or acrid. Check in on other WIRED-recommended travel mugs here.

Ohom

Ui 3 Self Heating Mug Set

$105 Amazon

Almost every self-warming mug set has some problem or another. Most are a little fugly. Many overshoot their target. Some are strangely complicated for a device whose main function is “heating element.” This Ohom mug set, with a warmer and paired mug, manages to do two things simply. It keeps your coffee heated to a pleasant 130 degrees Fahrenheit or above, the ideal temperature at which sweetness and aromatics find their most wonderful equilibrium.

It does so while remaining a pleasant cup to drink from: The Ohom mug is a classic and handsome 12-ounce ceramic mug, with a slight taper toward the top and a thin handle that's comfortable to hold. A lid is included but optional. And unlike some “self-heating mug” designs, you can wash it in the dishwasher or dunk it in the sink. After WIRED reviewer Simon Hill tried out hot plates and smart mugs and travel mugs for years, the Ohom Ui 3 was finally the solution that best mixed ease, functionality, and the little aesthetic niceties that make life pleasant.

The base of the mugset is a little induction hob, which heats up metal in the base of the Ohom mug. When it's not warming your coffee, the base can also wirelessly charge your phone, AirPods, and other Qi-compatible small devices at 15 watts. The pad will heat up a little (but not a lot) when in use. It pulses purple when it's heating a drink, blue when it charges a device. But especially, drinking from the Ohom feels just like drinking from the cup you would have chosen, even if you weren't using a warmer set.

But note you'll have to plug it in: It charges via a USB-C cable that’s about 5 feet long, with a power adapter. The charging base is less pretty than the mug. And there's no temperature adjustment: 130 degrees is my ideal temp, but it might not please people who want their coffee hot enough to inspire an immune system response. Mugs that are less full get a little warmer but never too hot or burnt.

If the Ui3 is too small for you, Ohom also has a heftier Ui+ model ($108) that holds 18 fluid ounces. A backup Ohom mug can be had for $36.
