Generally speaking, it’s not difficult to sell most people on the benefits of a portable power supply. The versatility and convenience of various types of power supplies and generators speak for themselves. Before springing for just any old model, you need to ask yourself a few questions. Be sure to mull the following when making any auxiliary power unit purchase.

Source of Power

Firstly, you should think about where your power supply’s juice will ultimately come from. Some portable generators use gasoline while others rely on diesel fuel. Quite a few models are diesel-electric hybrids. Some units are merely compact arrays of lithium batteries that store energy generated elsewhere. A few even create their own electricity using photovoltaic panels.

Type of Current

Without a doubt one of the most important decisions you can make in regards to a portable power unit is whether it’ll deliver AC power, DC power or both. Most portable power pack models are DC-only. Larger generator-style power supplies tend to give users the option of outputting either AC or DC power on demand.

Voltage & Power Output

A power supply is only as good as its ability to meet the demands of any given job. Popular models range from 12 volt jump-starters all the way up to 28 volt power supplies that can deliver up to 2,000 peak amps. Ensure that your chosen power supply can deliver the wattage you need at the right voltages.

Intended Usage & Compatibility

In the portable power supply arena, compatibility with a variety of gear is a critical concern. Most generators and power supplies boast standard sockets that will be compatible with most tools and appliances. If you need a power supply for a specialized purpose such as jump-starting aircraft, you’ll need to pay close attention to connector compatibility.

Size and Mobility

Nowadays, external power supplies come in all shapes and sizes. Where you plan on taking a power supply will inform your decision to a great extent. Clearly, smaller power packs can be taken pretty much anywhere. Larger, high-output models must be equipped with wheels and handles to provide an acceptable level of mobility.

Something for Everybody

If you’re looking for a portable power supply, your decision won’t hinge on a single factor. You’ll need to take all of the aforementioned considerations into account when weighing the pros and cons of any given option. Fortunately, the perfect power supply unit for your purposes is out there if you do your research.
