Battery Life Indicator
Docking Coaster & Charging Your Mug
Auto-Off Sensor
The Battery Life Indicator lights show the battery
level at Low, Medium or High.
Note: The first light will pulse red when battery life
is below 10%.
Your Nextmug Ultra comes with a Docking Coaster
that charges the mug. To use, insert power adapter
into a standard 120 volt wall outlet and plug power
cord into the Docking Coaster. Dry mug and
Docking Coaster thoroughly before charging.
When fully charged and using either lid, your mug will
maintain its temperature for up to several hours while
undocked. To enjoy your mug for longer periods of
time, use continuously with the Docking Coaster.
While docked, the Battery Life Indicator lights pulse
to show the current battery charging level. When
battery is fully charged, all three lights will be solid.
If the mug is On but liquid is not present, all lights will blink simultaneously after approximately
10 seconds and the mug will automatically turn Off after 60 seconds.
If the mug is On and liquid is present, the mug will automatically turn Off when it has not been
moved for 2 hours while docked.

and docking coaster thoroughly before charging.
Unplug power supply from the wall when not in use and before cleaning. To clean the power supply and

Do not touch hot surfaces inside mug.
Use only the power supply and docking coaster provided with the mug for charging. Do not use any other
third-party accessories.
It is highly recommended that you use the travel lid that came with your Nextmug whenever traveling to
help prevent spills.
This product is intended for use with consumable liquids such as coffee or tea.
Use caution when consuming hot liquids.
Ensure any Nextmug lid is secured firmly to avoid spilling. All Nextmug lids are compatible across all
Nextmug models.
Close supervision is necessary when a Nextmug product or any appliance is used near children.
If any of the instructions provided are not followed, or if the equipment is used in a manner not specified

material can occur.
Save these instructions.
Your mug comes with two lids: (1) a Spill-Resistant Lid (for use around the house or office); and
(2) a Spill-Resistant Travel Lid (when you’re on the go). Use either lid to keep your beverage at the
selected temperature longer while undocked. Choose the lid that’s right for you or choose not to use
a lid - your mug will maintain its temperature per the chart on page 8
