The BESTINNKITS Mug Warmer is a simple self-switching warmer for slow drinkers, best for slow coffee and tea drinkers at a desk. Rated 4.4 out of 5 across 2,142 user ratings. The main drawback: won't reheat a drink that has already gone cold. We scored it 4.3 out of 5.
A mug warmer can't make cold coffee hot, and the BESTINNKITS doesn't try; it slows the cooling so a slow drinker's cup stays pleasant for hours. The clever part is the pressure switch: it only heats while a mug sits on it and switches off when you lift the mug away. The catch is a plate that tops out at 131°F. That keeps coffee warm rather than scalding, and the last inch in the cup can turn stewed if you leave it too long.
NoFussDeal rates the BESTINNKITS Mug Warmer 4.3 out of 5 at $25.99. Last updated September 26, 2026.
A pressure switch under the plate turns heating on when a mug is set down and off when it is lifted, with a light to show it's working.
The glass-topped plate heats to a maximum of 131°F (55°C) to slow the cooling of hot drinks.
A 14oz ceramic mug with a flat base comes in the box, sized to sit fully on the warming plate.
A smooth glass top that wipes clean and a 72.8-inch cord that plugs into a wall outlet.

This model plugs into an electrical socket, not a USB port. It only turns on with the weight of a filled cup, a good safety feature. When on, it keeps coffee or tea good and hot, but not so … Read it on AmazonSB Price · December 9, 2023 · Verified

Wash the included ceramic mug before first use and wipe the warmer's glass top with a damp cloth.
Place the warmer on a flat, level surface near an outlet, away from papers and anything that could spill onto it.
It plugs into a standard wall outlet on its 72.8-inch cord; there's no power switch.
Pour freshly brewed coffee or tea into the mug. The warmer keeps drinks warm; it won't reheat cold ones.
Place the mug in the centre of the plate. The light should come on to show it's heating.
For most buyers, yes: we score it 4.3 out of 5. The BESTINNKITS mug warmer keeps a freshly made coffee or tea pleasantly warm for hours and turns itself on and off with the mug, which makes it easy to trust on a busy desk.
Rated 4.4 out of 5 across 2,142 user ratings, with 71% giving it five stars and 6% one star.
Won't reheat a drink that has already gone cold. Part-full or light cups may not trigger the switch.
Wipe the glass top with a damp cloth once it's cool.

The BESTINNKITS mug warmer keeps a freshly made coffee or tea pleasantly warm for hours and turns itself on and off with the mug, which makes it easy to trust on a busy desk. The included flat-based mug makes the most of its gentle 131°F plate. Know its limits: it won't reheat a cold drink, the last inch of coffee can stew, a part-full mug may not trigger it, and some units don't last.
A cheap, useful comfort for anyone whose coffee always goes cold. If you want your drink piping hot or precisely controlled, look at a heated smart mug instead.
