Portable Gas Refrigerator
On various outdoor and “prepper” forums, one common question is the availability of refrigeration in the absence of electric power. In most cases, the best option is to do as our ancestors did before the early 1900’s and simply live without this convenience. But in some cases (such as those with medicines that require refrigeration), a reliable form of refrigeration is needed.
Until recently, there were only three options, each with shortcomings. The first was to procure a generator to power a traditional home refrigerator. This is a poor solution, because the home refrigerator has an electric motor and thus requires a large generator (or very large inverter) and enough fuel to run it.
Another option is a “12 volt cooler” such as the ones shown here:
One of these can be a relatively good solution in many cases. While they don’t work as well as the big refrigerator at home, they are often adequate for the task. Compared to a home refrigerator, they require much less current. However, they draw enough current that they can’t simply be left unattended for long periods of time. The battery needs to be charged quite often, which entails having fuel to do so, or perhaps a relatively large solar charger.
The best solution has been the “3-way” Refrigerator. This type of refrigerator is commonly used in RV’s, and runs on 120 volts, 12 volts, or propane gas. They typically use about 1/2 pound of gas per day, meaning that a 20 pound tank will last about 40 days. In other words, storing fuel for long-term use is a definite possibility. Here are some examples:
The disadvantage of this type of refrigerator is that it is not portable. It is designed to be mounted permanently and, at a minimum, you would need to construct a cabinet to house it.
This objection has now been solved, however, with the following portable 3-way refrigerators:
Like the other 3-way refrigerators, these will operate on either gas, 120 volts, or 12 volts. But they are designed for portable use, and come with the hardware to hook it up to a portable LP tank, the type available everywhere. For those who absolutely need refrigeration “off the grid,” this is a very viable option.
