Excellent item for car use. It fits the cigarette lighter unit plug, and rapidly heats your hot drink while on the move. just the job,throw it in the car and heat up the water when you need it. Ok it take's about 9-10 mins for a cup but stuck out somewhere it's a luxury. Unlike most men, my dad likes his beer with the chill taken off. This is great! Every time we go into a pub (most days actually), I take this item with me and warm his beer up. I keep it in the car so it's very handy. Great when you are out and about and away from coffee shops. Takes a while to heat up but not too long and I would recommend. Ideal to use for: Baby bottles Drinks Heating water and much more
