Are Metal Cables Safe?

How Safe Are Metal Phone Chargers?

Tech Energi’s signature metal charging cables are certainly uncommon on the market. This leads some to question if the reason for this is related to safety. After all, isn’t the entire purpose of the cable’s casing supposed to be that it insulates? And isn’t metal the polar opposite of an insulator? Well let’s take a look inside a Tech Energi cable and see how safe they actually are.

 

What does the inside of a Tech Energi metal cable look like?

Tech Energi’s cables are cladded in a suit of steel armour in the most literal sense. Its segmented design strikes a balance that allows the cables to bend and flex with ease, while each individual segment is rigid, making the cable immune to self-tangling and knotting, and also reducing the angle of bends, resulting in less damage from typical long-term use.

A PVC jacket is locating underneath the steel casing, providing the layer of insulation one might expect from a regular charging cable, but with a significantly reduced risk of external wear, cracking, and splitting thanks to the casing which reaches all the way to, and includes, the connector heads at either end.

Multiple distinct layers within the PVC jacket keep the innermost tinned copper wiring protected against short circuits from inside the cable.

So to alleviate any concern, Tech Energi’s metal charging cables are not only safe, but in fact safer than standard plastic cables in regard to risks of exposed wires. And why shouldn’t they? They’re not marketed as ‘luxury-grade’ just to disappoint.

And if you’re still not convinced, all Tech Energi products are automatically eligible to be registered for free lifetime warranty upon purchase, so in the unlikely event that a cable is faulty, you can have it replaced with minimal hassle.
