A Smart Mug That Brews and Holds Temperature
The
Nuwave Smart Mug is a heated mug that also brews. A drinker picks a coffee,
green tea or black tea preset, adds grounds or leaves, and the mug does the
rest. It relies on immersion brewing, which means the grounds or leaves steep
directly in the hot water instead of water being poured through them. Once the
brew is done, the mug holds the drink at a set temperature. Nuwave describes
the aim as bringing out the full depth and aroma of each cup.
Temperature and Controls
Nuwave
lists temperature control in 1°F steps, from 70°F up to 205°F when brewing.
Warm and Hot settings keep a finished drink where it is, while a Brew button
starts the Coffee, Green or Black presets. A Precision Warm Mode is set to
98.6°F, body temperature, for gently heating milk, baby formula and other
delicate liquids, and a 2-hour timer shows when to discard formula. A soft-glow
display shows temperature, timer and battery life, and the mug shuts itself off
when it detects no water.
Battery and Charging
The mug
draws 50 W for heating and carries a 4,900 mAh lithium-ion battery from Samsung
SDI. Nuwave says it keeps a drink warm for over 5 hours at certain
temperatures, and lists 5 to 5.3 hours with the lid on at 135°F. The charging
base has a three-prong smart data connection, accepts AC or USB-C and ships
with a 6-foot cable. It has three drainage holes that redirect water leaks away
from the charger. The base needs a power source of at least 12 volts and will
not turn on at 5 or 9 volts, so Nuwave advises using the original cord and
plug.
Materials and Cleaning
The
interior rim and filter are vacuum-sealed, double-walled 18/10 stainless steel
with no coating. The lid is BPA-free Tritan plastic with a built-in steam vent.
A reusable double-layer steel filter means no paper filters or tea bags, and
Nuwave says it keeps the natural oils and flavors of the drink. The lid, filter
and filter lid are dishwasher-safe, and the mug itself is waterproof for quick
rinsing. These material and flavor statements are the company's own.
Using It Well
Nuwave
says the mug needs at least 3 oz of liquid. With about 2 oz or less and the lid
off, it may hold heat harder, so the last sips can feel hotter than expected,
and the company suggests switching it off near the end. Coffee grounds, tea
leaves and the filter can also affect the temperature reading. For use in a
car, Nuwave points to a Type-C charger in a 12 or 24 volt lighter port, and
does not recommend brewing while driving.
