This portable car heating cup is an absolute lifesaver, and i genuinely use it every day! The fact that it handles both 12v and 24v makes it versatile for different vehicles. I mostly use it to heat water for tea during my morning commute, and it saves me a fortune on motorway service station drinks. The 500ml capacity is perfect for two decent cups. It heats up surprisingly fast and the design is sleek (i chose white). If you spend a lot of time driving, this electric kettle is an essential, reliable piece of kit.
