Wagan 14 Liter 12v cooler/warmer is an essential item for anyone who gets hungry or thirsty when driving in their vehicle. It is perfect for family road trips or anyone who drives frequently. Save money and time by enjoying food and drinks on the go inside your vehicle. Reduce or eliminate stops at fast food joints during road trips. Save gas by avoiding the line at the drive thru. Use this 12v cooler/warmer to keep food and beverages cool without messy ice, or keep them warm instead. Its 14 Liter capacity holds up to 12 soda cans, and even standard size water bottles fit inside too. Safely pack healthy snacks like fruit, yogurt and sandwiches. Simply place the cooler either on the floor of your vehicle, or directly on the seat secured with a seat belt. Then plug the 12v adapter into your vehicle's 12v DC outlet and slide the switch on the back of the cooler to either hot or cold. If hot setting is selected, the interior stays warm and heats up to a maximum of 140 Degree; for cold setting, the interior stays cool and reaches a maximum of 32 Degree-36 Degree F below room temperature. For optimal cooling, pre chill items in the refrigerator to assist the unit to reach the lowest temperature as quickly as possible. Anything left inside the unit will stay cool for some time after the unit has been disconnected from 12v DC outlet or turned off. However, internal temperature will equalize to external surrounding temperature over time. A hot/cold/off switch has indicator lights for quickly viewing which temperature mode is in use. Its extra long 9 foot DC power cord extends to your vehicle's back seat area, so it can be easily accessible for anyone riding in your vehicle. The built-in shoulder strap allows for easy transport so you can easily take it anywhere you go. Power consumption is 48 watts. It also has a built-in fan and 10A fused plug. An optional AC adapter accessory is available (Wagan item 9903) for additional use in the home, office or hotel (sold separately).
