When OnePlus announced a USB Type-C cable for just £3.99, we were all impressed.
But a Google engineer has warned customers against picking up the bargain accessory.
According to Bensen Leung, a Google engineer who has recently reviewed a number of USB-C accessories, the cable “may cause damage to your charger, hub, or PC USB port”.
However, he admits that there is less risk using the cable with the OnePlus 2, because that particular device doesn’t feature fast-charging.
“But you should still not have these cables around in case you get a newer fast-charge capable tablet, phone, or laptop,” adds the engineer, who has been nicknamed the ‘USB Vigilante’.
According to Leung, the problem is that the OnePlus USB-C cable uses the wrong identifier resistor, and calls the company’s accessories “out of spec”.

He says the “riskiest state” would be plugging a fully drained phone into a legacy adapter with the “bad cable”.
That’s because the charge that a phone draws is on a curve, so the device draws less current as you get closer to 100% capacity.
With a drained phone, you’ll be drawing higher current; if the charger is poorly made, you might be getting the wrong voltage – both combined means trouble.
