How to Measure Current Draw of a Portable Tire Inflator159

Introduction

Portable tire inflators, also known as car air compressors, are essential tools for any vehicle owner. They allow you to quickly and easily inflate tires to the proper pressure, ensuring optimal performance and safety. However, before using a portable tire inflator, it is important to measure its current draw to ensure that it does not exceed the capacity of your vehicle's electrical system.

Understanding Current Draw

Current draw refers to the amount of electrical current that a device consumes. It is measured in amperes (A). The higher the current draw, the more power the device requires. Exceeding the current capacity of your vehicle's electrical system can lead to blown fuses, damaged wiring, or even a fire.

Measuring Current Draw

To measure the current draw of a portable tire inflator, you will need a multimeter. A multimeter is a versatile tool that can measure voltage, current, and resistance. Here are the steps on how to use a multimeter to measure current draw:
Set the multimeter to the DC current (A) scale.
Connect the positive (red) lead of the multimeter to the positive terminal of the tire inflator.
Connect the negative (black) lead of the multimeter to the negative terminal of the tire inflator.
Turn on the tire inflator and let it run for a few seconds.
Read the current draw on the display of the multimeter.

Interpreting the Results

Once you have measured the current draw of the tire inflator, compare it to the current capacity of your vehicle's electrical system. You can find this information in your vehicle's owner's manual. If the current draw of the tire inflator exceeds the capacity of your vehicle's electrical system, you should not use the inflator.

Tips for Reducing Current Draw

If you find that the current draw of your portable tire inflator is too high, there are a few things you can do to reduce it:
Use a smaller tire inflator.
Inflate tires to the recommended pressure only.
Avoid using the tire inflator for extended periods of time.
Connect the tire inflator directly to the battery terminals instead of the cigarette lighter socket.

Conclusion

Measuring the current draw of a portable tire inflator is an important step to ensure its safe use. By following the steps outlined in this article, you can easily measure the current draw and take the necessary precautions to prevent any potential electrical problems.
