This incredibly discrete coffee cup called the The PowerLine PowerCup, looks like a regular mug, however it's actually a power 200/400 Watt mobile inverter. This mug allows you to plug in electronic devices in your car, without having to drain out your cars battery. It even comes equipped with a USB slot.
The nice thing about the design of this inverter is that it can fit into a car's cup holder and it doesn't take up much room. This would be great for long car rides or road trips, especially for the passenger. No need to worry about your laptop's battery running out. Or maybe you have kids to drive around, so why not plug in their favorite game or movie, and not have to hear them say, "Are we there yet," a million times.
The PowerLine PowerCup is uber convenient and makes for a great gift as well.
