Yes it can! We designed the BOLT self warming mug to be the perfect addition to any desk during the work day. If you travel with your mug, you can also use any USB Type C to make sure your coffee is heated all day long and in any location.
When the BOLT temperature control smart mug is plugged in and on Charge mode (pulsating green light), you can touch and hold the power button to engage the Heat AND Charge mode. Simply select your temperature setting and you will have hot coffee while you're charging.
The charging will take slightly longer as some power is diverted to the heater, but you shouldn't notice a large difference.
