Take them with you wherever you go
Portable fridges are mostly powered by 12V DC – from car, RV, camper or boat 12V cigarette lighter sockets.
Some can also be powered directly with 110V AC, others need a 110V AC to 12V DC adapter for that. Smaller ones with capacities of 1 cu ft or less are shaped like normal cooler boxes, larger ones are shaped like small chests which can also be used in upright configuration. Some have wheels and collapsible (suitcase style) handles for ease of transportation. Most if not all of them have rugged plastic housings, which can survive several years of normal use.
One of the most popular portable fridges is this stylish white or blue Portable 6 Can Mini Fridge Cooler and Warmer.

FORGET A COOLER FULL OF ICE: The thermoelectric system in the Cooluli Cooler and Warmer allows for easy switching from beverage cooler to food warmer! Ideal for use on camping and road trips, picnicking, or for people who spend time in their vehicles. Keep your drinks cold and refreshing, no ice necessary! Not to mention it holds up to 15 12-ounce cans or whatever else you want to bring on your next road trip.
EASY SWITCH FROM COOLING TO HEATING: Take the cooler/warmer on the go and transition from cooling to heating with the flip of a switch! Easily fits in the back seat and plugs into the cigarette lighter with the included 6 and a half foot DC power cable to reach the back seat in any car regardless of the size. Cab and truck drivers love our product to keep them on the road and avoid wasting time and money at rest stops.
AC/DC ADAPTERS INCLUDED: The Cooluli Cooler & Warmer comes included with AC and DC power adapters – Easy to go from indoor 110V (AC) to car use by plugging the appliance into the car cigarette 12V (DC) adapter. The AC wire is 6 ft. long and the DC wire is 6 and a half ft. so finding an outlet won’t be a problem. Also great for use on boats, RVs and while camping or picnicking.
DURABLE DESIGN FOR TRAVEL: The Cooluli 15L Cooler & Warmer is designed with car travel in mind. Built from high quality, sturdy plastic meaning it's lightweight and easy to carry even when full. The cooler is very well insulated and will keep beverages and food cool or warm for a good deal of time after the cooler/warmer is unplugged. This cooler/warmer is essential for anyone who loves taking road trips or going camping!
THERMOELECTRIC COOLING SYSTEM: Thermoelectric cooling shouldn’t be confused with refrigeration. Instead of blowing Freon with a fan (refrigeration) the Cooluli Electric Cooler & Warmer blows air from the metal inside to the outside with the help of an electric fan. This means the cooler/warmer is 100% safe and Freon Free. Since thermoelectric cooling works without refrigerants the Cooluli Cooler & Warmer is also environmentally friendly!
110V AC to 12V DC (5 Amp) adapter – enables your 12V portable cooler / warmer to work on 110V AC power.
This way you can use your portable or car fridge also at home, in the office, in a hotel, at a camping site – wherever AC power is available.
It is also great for cooling (or warming) your mini fridge at home before you hit the road.
Principle of operation
All portable refrigerators work on the Peltier principle. Some of them can also be used as warmers, not just coolers – by flipping the switch or reversing polarity of the 12V DC socket, the interior is warmed and external part of Peltier cooler is cooled.
Depending on your needs and circumstances, you need to make some choices:
1. Size: the smaller cooler box units can be carried with one hand, but of course have very limited capacity (1 cu ft or less). Larger portable fridges are roomier, but also bulkier and heavier need to be wheeled and are not so suitable for frequent transportation by hand. Can be ideal for an RV, SUV,
2. Power source: 12V DC only or also 110V AC. If you want to power your portable fridge on the road in your car, boat, RV, etc. and from the grid (at home, at camping site), then the dual power unit is an ideal choice. On the other hand, 12V / 110V units can be heavier and more expensive. You can also buy 110 V AC to 12V DC adapters cheaply an power any 12V cooler from the grid. You will have to remember to take the adapter & cables with you though.
3. Heating and cooling or cooling only unit: Again depends on your needs. The combined units are ideal for cooling foods and beverages and ideally keeping a meal or coffee and other beverages warm. In principle, any Peltier cooler can be reversed (hot side becomes cold an vice verse) by simply reversing DC voltage polarity on the Peltier cooling / warming element, thereby reversing the functions of the cold and warm sides.
The combined heating & cooling units should not be much costlier. The problem is, if the unit does not support the warming function, you can not simply change the DC voltage polarity yourself – the fan might also turn in the wrong direction or some other component can get damaged.
