IP Ratings Explained

Updated: Mar 19, 2021

If you have been looking for a home charge point, ev charging cable or portable charger you may have had a look at the technical specifications and wondered what most of it all means. Lets kick off with IP ratings and try to keep it short and sweet.

If the product you are looking at does not display an IP rating then you should probably keep on looking. IP rating is also known as Ingress Protection or International Protection ratings are defined to the international standard of EN 60529 (British BS EN 60529:1992). This standard is used to define the levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies such as dirt and moisture.

What do the two digits in an IP Rating mean?

The rating consists of the letters IP followed by two digits, the higher the number the better the protection. Sometimes a number is replaced by X, which indicates that the enclosure is not rated for that specification.

IP65 = First Digit – Solids

The first digit indicates the level of protection that the enclosure provides against the ingress of solid foreign objects, from tools or fingers that could be hazardous if they came into contact with electrical conductors or moving parts, to airborne dirt and dust that could damage circuitry.

IP65 = Second Digit – Liquids

The second digit defines the protection of the equipment inside the enclosure against various forms of moisture (drips, sprays, submersion etc).

Why Teison put so much importance on IP ratings.

We want to make sure our products are the best they can be. We only use quality raw materials and electronics in our products. No matter how good the materials if the product allows moisture or foreign objects to enter then the product will have a much shorter life than one that doesn't.

Teison Portable Pro range has industry leading IP protection with a rating of IP67 which is equal to an iPhone 10.
