Factors to Consider Before Buying a Cordless Air Compressor

Cordless air compressors are not as powerful as the corded models. However, you still need to ensure that you buy the right model for the intended application. Rather than opting for the cheapest model, it is advisable to get one that offers the best value for money. In this regard, these are some of the important things you should consider while shopping for the best cordless air compressor:

PSI Range

Different air compressor tire pumps are designed to deliver a certain amount of pressure. Depending on the intended application, you need to check whether your preferred air compressor hose is suited for your operations. This is often expressed in Pound-force per square inch (PSI).

For instance, if your tires need to be inflated to 100 PSI, you should go for a unit with a max pressure range of 120 PSI or even higher. Basically, it is advisable to go for a compressor with a range that is about 30-50 PSI more than what you are trying to inflate.

Most of the best low-pressure cordless air compressors have a PSI range of between 30 and 150PSI. Such a unit may also be used to power an assortment of pneumatic tools since most of them only require about 120 PSI to run. Make sure to use a suitable air compressor hose for your operations as well.

Battery Life

Cordless electric air compressors are entirely powered by rechargeable batteries. As such, the performance of the device will partially depend on the type of battery it has. Most of the leading portable mini air compressor brands use 12 V batteries on their units. Even so, you should get one that highly efficient on the battery.

To begin with, you need to check how long the battery lasts, or rather the number of times you can use the tool on a single charge. Again, you need to ensure that the battery charges rather fast to ensure increased uptimes. If not provided by the manufacturer, you should ensure that you get the right battery pack for your compressor. Using the wrong battery may cause the unit to malfunction.

Charging Cord

Most of the best portable electric air compressors com to feature an AC charging port. In most cases, this port may only be connected to mains electricity using the appropriate charging cord. If it is meant for use on car tires, you should get a model that comes with a cigarette lighter charging cord. With such a cord, you only need to plug it into the cigarette lighter port in your car to charge the air compressor battery.

Speed

How fast can your preferred battery-powered air compressor deliver pressurized air? The rate of airflow in an air compressor portable is measured in cubic feet per minute (CFM). This will determine how fast the tool can inflate a tire. Some of the best battery-powered air compressor models have a CFM range of 0.6 to 2.8 CFM.

Automated Cut-Off

With this feature on your compressor, you do not need to be physically present the entire time the tire is being inflated. You only need to plug the air hose into the nozzle, preset the required tire PSI and start the compressor. Once the preset PSI is achieved, the compressor will automatically stop the inflation process and probably shut down.

Air Tank Capacity

A good number of the portable air compressor models feature a built-in tank for holding compressed air. This stored air may be used to inflate tires or power pneumatic tools, without having to start the air compressor. As the air in the tank is used, the pressure will decrease. When the preset tank threshold level is reached, some models are designed to turn the compressor on automatically. Once the desired pressure is reached, the motor will turn off. Most of the best portable units have a capacity of between 1 and 6 gallons.

Additional Nozzle Attachments

Choose a model that comes with multiple nozzle attachments. This makes it possible for you to connect the tool to an array of chuck sizes as well as an assortment of pneumatic tools. Such attachments will give you a tool that can be used for a variety of purposes around the home.

How to Use a Cordless Air Compressor

Also referred to as portable tire inflators, cordless air compressors may be used for an array of applications. Using such a tool to inflate your car or motorbike tire is rather straightforward. This is particularly the case with the models that feature an automatic cut-off capability. Here are some tips to help you use a cordless air compressor properly:

Making the Connection

Most of the leading modern air compressors come with an assortment of attachments to suit an array of tire valves and other inflatables. Almost all the modern air compressors come with all the tools and attachments you need to inflate your tire. The tire chuck is the tinny tool that attaches between the tire valve and the nozzle of the air hose. You need to ensure that this connection is made properly, such that the chuck depresses the little valve switch inside the tire valve in order for air to flow.

Preset the Shut-Off PSI

If the model has an automatic shut-off feature, you should calibrate it to the right PSI level of the tire or item you are inflating. Thereafter, you can start the compressor, depression the hose valve and lock it in position. The compressor will continue inflation until the order PSI is reached. It will then shut itself down automatically to prevent overfilling. Regardless of what you are inflating, it is advisable to keep the compressor dry at all times.

As an electrical device, a portable air compressor can be shorted if it gets wet whilst operating. They also typically include a pair of rotating, metal screws that suck in air. Storing in a moisture-rich environment can cause the screws to rust, and eventually break the compressor down.

Monitoring the Pressure

If the cordless inflator does not have an automatic cut-off capability, you will need to monitor the pressure manually. This is particularly the case when topping up a tire. If left unmonitored, the compressor will overfill the tire and may even cause it to burst. With such a model, you need to depress the hose trigger continuously, while monitoring the pressure gauge. Once the desired PSI level is achieved, just release the trigger to stop airflow. You should then proceed to shut the compressor down.

Using an Air Compressor

Ready to Use a Cordless Air Compressor?

As a driver or car owner, you probably have had a flat tire in the middle of nowhere. In such a case, a portable electric air compressor will come in handy. Such a tool may also be used with a range of pneumatic home tools. However, you just have to invest in the right model in order to get this versatility. Furthermore, you can opt for an array of brands, such as DeWalt, Ryobi, Milwaukee, Lowe’s air compressors, and many more.

Just like the five models reviewed above, your preferred air compressor should feature sturdy construction, be lightweight and still powerful enough for the intended application. With this guide, you should have an easy time choosing the best cordless air compressor. If you are using cordless air compressor consider buying the quality air chucks with a gauge. These are the small, portable tire inflators that connect to the tire to inflate or deflate the tire. Air chucks with an inbuilt gauge may also be used to check tire air pressure.
