Keeping beverages, food, and essential medications cold while on the road can be quite challenging. That challenge has been met by the iceless cooler technology of portable thermo-electric coolers which are often referred to as 12 volt coolers. If you have ever spent any amount of time traveling by passenger vehicle, semi-truck, or motorhome you are likely all too familiar with the difficulty in keeping food cold and usable in a standard travel cooler. Conventional cooling methods such as bagged ice and freezer cold packs often leave the cooler bottom full of warm water and soggy wet food.
Enter the 12 volt cooler. These 12 volt coolers act like a portable mini-fridge as they are powered directly by electricity produced by the vehicle and delivered by the accessory power outlet (ie. Lighter socket outlet). Over the years there have been many performance and power saving developments made in this form of portable food storage which are greatly appreciated by travelers far and wide. Professional truck drivers and those owners of motorhome campers enjoy low power consumption and low noise level operation.
Portable electric coolers are best used for safe storage of dairy products, deli meats, cheeses, condiments, and beverages. They are also the perfect solution for the safe storage of temperature sensitive medications. These units generally cool to 40 degrees below the ambient temperature and never reach temperatures of freezing or below.
Just like your home refrigerator, care and cleaning are an occasional requirement. Cleaning the inside of a portable electric cooler is done with a rag or sponge dampened with a mild, easy to remove soap or diluted bleach water solution. Simply wipe down the inside and outside of the cooler to clean. The only required maintenance is the removal of dust from the exterior cooling fan. This is done using a can of canned air or a common air compress set to a low air pressure level. Keeping the exterior cooling fan clean helps to keep the cooler operating quietly and efficiently.
There are many options now available which are being produced by well known and trusted manufacturers such as Black and Decker, Coleman, Koolatron, RoadPro and Wagan Tech. These units are all quite attractive in design, highly reliable and extremely cost effective, especially when compared to the cost, hassle and losses experienced when using conventional travel coolers. Put an end to the so called swamp coolers of yesterday and travel in comfort.
