OnePlus, Apple, cables and book covers

These days there have been reports on two sides of the same product: cables and power adapters, often dismissed by users, are more important that it may seem.

On one end we’ve got OnePlus, who has been victim of a detailed analysis by a Google Engineer. He found that this maker should be using 56kΩ resistors on their OnePlus 2 power adapter, but instead they’re using 10kΩ resistors.

As Ars Technica explains, these adapters are suitable for OnePlus smartphones, for sure, but you shouldn’t use it on other USB-C connector devices such as the Nexus 5X/6P or the Chromebook Pixel.

And then we’ve got another detailed analysis, this time exploring the inside of a MacBook Power Adapter. The result, as the text itself, is surprising, and the expert reviewing it calls it “an impressive piece of engineering

We usually criticize Apple and other makers for selling us expensive cables. Sometimes we can be right, sure, but others it seems quite clear that an expensive cable or power adapter has a reason to be that expensive.

Not in the case of HDMI cables, by the way. Don’t buy expensive ones.
