GT-2 support
Set up the 16oz heated mug and two-function base.
GT-2 is a connected desk system with three temperature presets. It does not use the GT-1 app, Bluetooth, removable battery base or charging coaster.
01
Start heating
Connect the supplied 12V / 3A adapter, place the matching mug on the base and hold the power control for three seconds.
02
Choose a preset
Select 95°F, 131°F or 167°F. GT-2 maintains warmth; it is not a rapid water boiler.
03
Switch to phone charging
Remove the mug, let the base cool for about three minutes, then center a compatible wireless-charging phone on the dry base.
Why is the phone not charging on the GT-2 base?
Confirm the mug is removed, the base has cooled for about three minutes, the phone supports compatible wireless charging, and the phone is centered. Thick, metal or incompatible cases can prevent charging.
Can I put cards, coins or metal objects on the base?
No. Keep bank cards, coins and other metal objects away from the charging surface.
Can I use a GT-1 magnetic powered base with GT-2?
No. GT-1 and GT-2 are separate systems. Use only the matching GT-2 base and supplied adapter.
What should stay dry?
Keep the GT-2 base, power connector and adapter dry. Disconnect power before cleaning and do not let liquid collect on the base.
Choose & use
Questions buyers ask before choosing a smart mug.
What temperature range does the GREATIC GT-1 smart mug offer?
The GT-1 temperature range is 30-65°C / 86-149°F. Use the mug controls or companion app as described in the manual.
How long does the GREATIC heated coffee mug keep coffee at 55°C?
At 55°C under stated conditions, GREATIC specifies up to 150 minutes for 10oz, 120 minutes for 14oz and 90 minutes for 16oz. Actual runtime varies with starting liquid temperature, room temperature, drink volume, selected temperature and battery state.
Which smart mug size should I buy: 10oz, 14oz or 16oz?
The GT-1 is offered in 10oz, 14oz and 16oz. Color availability and price are shown in the product selector.
Choose 10oz for a compact coffee, 14oz for everyday desk use, or 16oz for longer sessions and larger drinks. Compare GT-1 sizes →
Does the GT-1 smart mug work without the app?
Yes. You can select a drinking temperature with the controls on the mug. The companion app adds live cup temperature, saved drinks, battery status and a ready reminder.
What is the difference between a temperature-control mug and a mug warmer?
A plug-in mug warmer heats a compatible cup while it remains on a powered plate. The GT-1 measures and regulates the drink through its matched mug and removable powered base, so it can continue working away from the charging coaster for its battery period under stated conditions.

How do I connect the GT-1 to Bluetooth?
Follow the GT-1 manual in this order:
- Before the first connection, charge the mug for 30 minutes so it has sufficient power.
- Turn on Bluetooth on your phone and allow both Bluetooth and Location permissions when the app asks.
- Open the installed app and tap “Bluetooth Devices” at the top of the screen.
- On the device connection screen, tap “Add Device” and wait for the app to detect your cup.
- Select the detected cup, tap “Pair”, and follow the connection wizard until the product information screen appears.
- If the cup is not detected, press and hold the product power button for 5 seconds to enter Bluetooth pairing mode, then repeat the steps above.
The labels “Bluetooth Devices”, “Add Device” and “Pair” match the GT-1 manual and may remain in English inside the app.
What can I control in the GREATIC smart mug app?
Adjust the target temperature, name and save beverages, view the current cup temperature and battery status, and receive a reminder when the target is reached. See app features and download options →
Which app should I download for the GREATIC GT-1?
On iPhone and iPad, scan the iOS QR code or search “Greatic” in the Apple App Store. On Android with Google Play, scan the Android QR code or search “GTempura”. In other Android app stores, search “Greatic”. Open the official app page →
What should I do if the app cannot find my GT-1 mug?
Confirm the mug has charged for 30 minutes and that Bluetooth and Location permissions are allowed. If detection still fails, hold the product power button for five seconds to enter pairing mode, then run device detection again. Open the illustrated Bluetooth guide →
What if my Android phone does not have Google Play?
When the official Android APK is available, download it only from the GREATIC App page. Do not install APK files from unofficial search results, chat messages or email attachments. Check official Android download availability →
Care
Cleaning and safety questions before you buy.
How do I clean a self-heating coffee mug safely?
Wipe clean only. Do not rinse, soak, dishwash or microwave the mug. Empty the mug first and use a soft, slightly damp cloth on the drinking vessel only.
Is the GREATIC heated mug dishwasher or microwave safe?

Which parts of the smart mug must stay dry?
Keep the mug, magnetic interface, powered base and charging contacts completely dry before reconnecting them. Moisture on the magnetic or charging contacts can damage the powered system.
Can I keep using the mug if the base or charging cable is damaged?
