The Cooluli 4L Cooler & Warmer is perfect for home and office use as well as in the nursery, office or dorm room. It's capable of holding six (6) 12 ounce cans. Our thermoelectric cooling system is popularly used as a beverage cooler, but the warming function shouldn't be ignored. Save time in the morning by bringing your breakfast with you or save money by bringing your lunch and keeping it warm all day. Plus, we included both AC, DC and USB power cords to make the switch from standard (110V) to car (12V) to USB 2A power bank easy and convenient. No need to buy extra wires! We made it incredibly easy to switch from the cooling to the warming function as well. An easy-to-read display lights what setting the appliance is on and can be changed by simply flipping a switch. The Cooler & Warmer produces almost no noise (perfect for next to your bed to save a walk to the kitchen) and is compact and sleek enough to put on a desk at work. Cleaning the interior and exterior is extremely easy, simply wipe them down and the storage shelf inside is removable as well (for even easier cleaning as well as expanding to hold four 16 oz. bottles.) The Cooluli Cooler & Warmer also comes in five different colors: white, blue, pink, fuchsia and cow pattern.
