Quick answer

Which GT-1 size should I choose?

Choose 10oz for a compact coffee portion, 14oz for everyday flexibility, and 16oz for longer work or study sessions. All three sizes use the same 30-65°C temperature range and replaceable magnetic powered-base concept.

Away from the outlet

Why choose GT-1 when plugging in is inconvenient?

Once the matched powered compartment is charged and attached, GT-1 can regulate the drink away from the charging coaster for the model’s stated battery period. Actual runtime varies with starting temperature, ambient temperature, drink volume, set point and battery state.

Outdoor meals and work breaks
Bring a charged GT-1 to a campsite table or outdoor work break without keeping the mug on a powered plate.
Patio or garden seating
Move from indoor coffee preparation to patio or garden seating while the matched powered compartment continues regulating the drink.
Meeting rooms
Carry coffee into a meeting without choosing a seat beside an outlet or keeping the mug on its charging coaster.
Balcony coffee
Use a small balcony table while the charged GT-1 powered compartment regulates the drink during its battery period.

Power-system boundary: GT-2 is the connected desk option; its dedicated base is not the GT-1 battery-powered portable system. These examples describe ordinary portable routines, not a waterproofing claim. Keep every magnetic and charging contact completely dry.

Portable power or desk-powered warmth

Choose the heating system that matches your routine.

Choose GT-1 for battery-powered temperature control away from the charging coaster. Choose GT-2 for a connected 16oz heated mug and a base that can charge a compatible phone after the mug is removed and the base cools.

Need more time?

Rotate a second magnetic powered base.

The GT-1 battery and control electronics are contained in the shared black removable powered compartment. The 10oz, 14oz and 16oz models use the same black charging-base system. A second £35.55 base can be kept ready and rotated when your routine extends beyond a single base cycle.

Only use the compatible GREATIC GT-1 system. Keep every magnetic and charging contact completely dry before reconnecting.
