Product Overview
The Misby Mug Warmer is designed to keep your beverages at an optimal drinking temperature, ensuring your coffee, tea, or milk stays warm throughout the day. Utilizing gravity-induction technology, it offers a convenient and safe way to enjoy your drinks without constant reheating.
This versatile device can maintain temperatures between 120℉-140℉ (40℃-60℃), perfect for those who enjoy their drinks slowly or get absorbed in their work.
Safety Information
Your Misby Mug Warmer is equipped with intelligent safety features to ensure peace of mind:
- Gravity-Induction Auto Shut-Off: The warmer automatically activates when a mug weighing over 0.8 lbs (13 oz) is placed on its heating plate and automatically shuts off when the mug is removed. This prevents accidental heating and saves energy.
- Temperature Control: Designed to maintain a warm temperature, not to boil liquids. This prevents overheating and potential burns.
- Surface Temperature: The heating surface itself is not excessively hot to the touch when a mug is not present, reducing the risk of burns from accidental contact.
Important: While the warmer has auto shut-off, always unplug the device when not in use, especially if pets or small children are present, to prevent unintended activation.
Setup Guide
- Unpack: Carefully remove the Misby Mug Warmer from its packaging.
- Placement: Place the warmer on a flat, stable, and heat-resistant surface, such as a desk or countertop.
- Connect Power: Plug the power adapter into a standard electrical outlet.
The warmer is now ready for use. No complex setup or additional operations are required.
Operating Instructions
Operating your Misby Mug Warmer is simple and intuitive:
