Don't Buy USB Type-C Adapters and Cables from OnePlus, Says Google Engineer

The adapter doesn't charge correctly and doesn't follow the recommended specification.

OnePlus's USB Type-C Adapter, currently sold on its website and on Amazon, is getting bad reviews for using a wrong electronic component, which causes devices--phones, tablets, and laptops supporting the new connector--to fail. The Chinese smartphone manufacturer is known for its low-cost smartphones with high-end features. The startup also makes phone cases and covers, power cables, power banks, and earphones.

Benson Leung, an engineer working on Google's Pixel C laptop, has been called a “USB vigilante” after posting brutal and honest reviews on Amazon. Two weeks ago, Leung wrote that he is already fed up with cables and adaptors from 3rd-party vendors that are not compliant with the standards. This weekend, he included the accessory from OnePlus, saying that it uses a different identifier resistor, a tiny electronic device designed to resist passages of an electric current.

Leung discourages people from buying the USB Type-C Adapter and Cable for the Chromebook Pixel or the Nexus 6P and 5X phones because the adapter doesn't charge correctly, and doesn't follow the recommended specification for power delivery identification. He found out that OnePlus is advertising the adapter as compatible, which is wrong.

“Since you are creating a USB Type-C plug to a USB 2.0 Micro Type-B receptacle assembly, you must use a resistor of value 56kΩ. According to our testing, your cable uses a 10kΩ pull-up, which is not legal when the other end of the cable or adapter is a legacy Type-A or Type-B connector or receptacle,” he explains. “By using this cable, your phone, tablet, or laptop computer may attempt to draw 3A, which may be more than the micro-b to A cable you attach to this adapter may be able to handle. This may cause damage to whatever cable, hub, PC, or charger you plug into this.”

Not all third-party adapters, however, received negative reviews. For instance, Belkin's USB-C to USB-A cable are excellent, Leung says, because it meets the USB Type C specification. He even praised the cable, saying that it's as good as the ones provided by Apple and Google. The iOrange-E USB Type-A to Type-C cable also got a positive review from Leung. The demand for USB Type-C connectors increased when Google launched the Nexus 5X, which doesn't ship with a Type-C-to-Type-A connector.
