Buyer's Guide: 12V Air Compressor

Choosing The Best 12V Air Compressor

For a 12V air compressor, 80 to 120 PSI versions are good enough for the simpler tasks. However, any air compressor with an output of more than 120 PSI can damage your car's battery. So, you should always go for compressors with an output of fewer than 120 watts. If you run your 12V air compressor in parallel with your car's battery, then you'll definitely get more juice from it. And when charging your batteries, make sure that they are disconnected from each other beforehand.

The function of a 12V air compressor is to inflate tires. For that, it uses a motor to pump air into the tire. That creates more pressure on the tire. If you want to use your 12V air compressor for longer trips, then you need one with higher PSI. One with a maximum tire pressure capability of a hundred and eighty pounds per square inch is ideal. You can get one with maximum power draw capability of a one-gallon tank capacity.

Before buying a 12V air compressor, be sure to check out the following features: warranties, manuals, cables and charger cords, voltage requirements, power source, and user manual. Check if your model has all the necessary features. For example, does it have the user manual? Does it come with any warranty card? Read the user manual thoroughly.

Make sure you buy an air compressor for your vehicle that can support the application you need it for. For example, if you're going to run heavy-duty sanding, then you might want to get a model that has higher PSI. On the other hand, a small high power draw model can run a single tire with a moderate power draw.

Always go for high-quality brands. A reliable brand will be able to provide durable components that will last long. Brands such as Craftsman and Bosch are known to produce good products. When buying a 12V air compressor, make sure you buy one that can work in your situation. This includes size and inflation requirements for your car tires.

You must consider the difference between inflation pressure and tire pressure when choosing a 12V air compressor. Higher inflation pressure will increase tire pressure. However, this isn't always the best option when working with heavy objects. It increases pumping time but may not necessarily improve your work performance. It's also not recommended if you work on difficult projects that require lots of pumping.

It's best to buy a 12V compressor that can support different sizes of tires. This is because tires vary in size. Know the size of tires you need so you'll be able to purchase the best 12v air compressors. Purchasing a compressor that doesn't support the amount of air pressure your vehicle's tire pressure needs could result in damage to your engine or possible electrocution.

Your purchase shouldn't only be about price. Make sure the model comes with a sturdy warranty card. Warranties protect the parts and the machine from common wear and tear. Shop around before making your final decision. Compare prices and models among various vendors before deciding on which 12V air compressor to buy.

If you're going to use your 12V air compressor in the car, you'll have to get a cigarette lighter socket. A car tire inflator, like the ones found in cars, is a must-have accessory for anyone who drives. Air compressors, in general, are used to increase air pressure in tires that don't have air pressure built-in. So, to start off, you'll need the appropriate car tire inflator. If you don't have one, you'll have to find one at a local hardware store, a department store, or check online for a readily available model.

Most 12V air compressors come with a digital control panel that lets you easily change the settings for different uses. Make sure the controls are easy to turn; this way, you'll be able to set the maximum air pressure you'd like to use in a quick and easy fashion. You should also check the air filter to make sure it's clean and clear of all obstructions. The tire inflator should have an inflator pump that is properly sealed. It should also have a long enough hose to reach all of the places on your car where you'll be inflating tires.

Another important feature in an air compressor is its duty cycle or its " Duty Cycle." The duty cycle tells you how often the compressor will run and at what PSI rating the compressor will draw. Be sure to choose a low PSI compressor that has a high PSI rating to save money. A model that has a high PSI rating but a low duty cycle will cost you more than a lower PSI model with the same rating but with a lower duty cycle.

Your final consideration when choosing your 12V air compressors is whether you need an oil tank or an electrical one. If you only plan on keeping your compressor charged up for short periods of time - say, for inflating tires - an electrical compressor would be adequate. However, if you plan on using your compressor on a regular basis and storing it for longer periods of time - say, so you can fill tires, keep it running properly, and so on - an oil-to-air tank will be your best bet.
