Pre-Purchase Considerations for 12 V Air Compressors

Finding the best 12 V air compressors for your workshop and roadside journeys is indeed a wonderful stroke of luck. However, after reading our detailed review, you must be happy to learn that they are not something out of your reach.

The top-notch picks that we have reviewed for you are available in the markets, and you can procure them to benefit from their features. The best air compressors will be making your life easier by providing you with quick and efficient service. However, we understand your condition of confusion while finalizing the one air compressor.

That is because the market will offer you many air compressors. To help you procure the best air compressor, we have devised this comprehensive buyer’s guide for you. So, glance at it and take careful notice of the factors we are going to tell so that you can end up purchasing the best quality 12 V air compressor!

Air Flow Rate of an Air Compressor

The first significant factor that you must not forget is to check the maximum airflow that your air compressor is offering you. Airflow rate is a crucial factor dictating the overall performance of an air compressor because it is indicative of the total air volume output that a compressor can produce in a given amount of time.

To be clearer, it is also expressive of the airflow speed that a compressor is capable of. You will see different manufacturers measuring it in cubic feet per minute (CFM). We strongly suggest you go for the air compressors that have a larger CFM.

Air compressors with the larger CFM spanning around 30 to 35 Liters per minute are the best ones to go for. Such compressors will also be matchless in terms of delivering excellent and high-performance.

The Capacity of the Air Tank

Another crucial factor determining the excellence of the air compressor is the maximum tank capacity that it offers. For example, you will see different models offering nominal to larger capacity for the tank.

We suggest you always opt for air compressors that have more tank capacities. Such air compressors will be helping you in accomplishing your tasks continuously without any breaks. If you are specifically purchasing a 12 V air compressor only for inflation of the nominal tires, then compressors with two-gallon capacities will be enough.

However, if you want to purchase them for the larger vehicles and other tasks at your workshop, we suggest you go for the models with the larger tank capacity. In either case, you need to make a careful decision to derive full benefit from its working.

Length of the Cord

Among other features, you must not ignore the cord length while purchasing the best air compressor. This is important because you will be creating a connection between the power socket of 12 V or battery and your air compressor. The cord length needs to be sufficient for the smoother transferal of the air to the tires without interruption.

Though the shorter cables will be enough for your motorbikes, you need longer cords in case of the larger vehicles. To save yourself from these worries related to the shorter cords, you need to opt for the 12 V air compressors with length span over a range of the 10 to 12 feet.

Also, there is a possibility for the attachment of the hose extensions so that you can get the other length. Therefore, making a prudent decision regarding the length of the cord is very important.
