What do you need to measure to know the pin size?

If you happen to have several chargers at your home or office and want to find out which one will go with your laptop. Then you should measure two types of diameters.

The first one will be the outer diameter. If you observe the charging pin carefully, you will see that it has two rims. The outer rim’s diameter would be the outer diameter. And the inner rim’s diameter is the inner diameter.

Now measuring it is really challenging as it is very tiny, and not many people would have the equipment to measure it precisely.

If you are still confused, then allow me to explain that the pin’s outer cover is the metallic part of the pin. It is the place where you will measure the outer diameter.

Then on the inside of the pin, you will see an inner part, it will be either made up of fiber or plastic. It is the size of the laptop’s charging port in some cases, however, for some advanced laptops, the outer part also gets in.

What is the advanced laptop pin size?

To be honest, there is no particular size for all laptops. Each manufacturer has a different tip size. Currently, there are seven types of tips for laptop pins. This is not it, each type is further divided into a range of outer and inner diameter.

The maximum outer diameter for the X tip type is 7.9mm, and the inner diameter will be 0.9mm. However, the tip length for all the laptops is 12 mm. It is the standard size of the laptop’s charger’s pin.

Now coming towards the main question, how can you measure it? If you think that it would be easy to measure the laptop charger’s pin size with a measuring tape, then you are wrong.

The best way to measure the pin is with a caliper. You might not get it easily, and many people will need to contact a technician to find the caliper.

If you have the caliper then you are supposed to measure the length and the cross-sectional area of the pin. This way you can measure the diameter.

Ensure that you know how to measure with that equipment because a slight difference can go a long way.

A guide to measuring the diameter with a caliper

To assist you a bit, here is a brief guide about how to measure the size with the help of a caliper.

  • First, you need to check the zero error.
  • To do so, close the teeth of the caliper, if the reading is zero and zero on all sizes then the zero error is removed.
  • Then get the charger.
  • Ensure that the pin is clean and that there is nothing on it.
  • Now hold the pin from the tip area.
  • Place it in the center of the caliper’s teeth.
  • Now tighten the screen of the caliper, and once it is tight.
  • Now take the reading, and ensure that you also note the points on the caliper.

Conclusion

Measuring the size of the charger pin is a hard thing, and not everyone can do this. It can only be measured with the right equipment. It is also very crucial to find the right port.

FAQs:

What if the charger is of the same measurement but still did not charge?

What to do to change the polarity of the charger?

You need to change the position of the charger to 180 degrees, and it will start working.
