There is no need to buy a 12 volt DC to 110 volt AC power inverter to run your 110 volt AC refrigerator or freezer from a 12 volt power source. Not only is this a dangerous way of getting the job done it can also get very expensive and there are some other options out there. We know of some awesome 12 volt DC mobile refrigeration technology and we can't wait to share it with you. It starts with the patented Swing Motor.
The Sawafuji Swing Motor is a true reciprocating compressor; it has only one moving part. It doesn't get any simpler. The piston is connected to an electro dynamic device which is powered by the use of magnetic fields. With this technology there is no need for bearings, cranks or con-rods, so less moving parts means less chance of failure. With only one moving part there is a very low friction loss which means this is a highly efficient compressor.
It has no high start up current draw because when it starts up it can simply move down just a fraction then return. Then it slowly increases the distance the piston travels each stroke until it reaches a full stroke. The Sawafuji Swing Motor does not need to perform a full stroke on start up unlike many rotary type compressors that must perform a complete cycle and need much more current to start.
Because this is purpose built and designed to be a portable refrigerator compressor it has to be engineered to take the harshest of mobile and high vibration conditions.
Convenient transportable freezers/refrigerators that run on any 12 volt power source. They can be used in airplanes, cars, trucks and boats of just about any size - basically anywhere there is a 12 volt power source (including wind generators and solar panels). 12 volt refrigeration is a wonderful idea for those living in remote areas too.
A combination of performance, durability, lower power consumption and consistent reliability are all things you should look for when considering which brand of portable refrigeration is right for you.
For some people just a basic 12 volt or rechargeable cooler will get the job done. But when you need maximum storage space and incredible cooling or freezing power with very little battery draw you must consider some other options. Most smaller less durable brands have a life expectancy of a year or less.
To date we there have been about 3.6 million units using the Swing motor sold world wide.
