OnePlus releases chart showing which devices can safely use its flawed USB-Type C cable and adapter
In a statement, OnePlus says that the cable and adapter is perfectly safe to use with the OnePlus 2. Those who purchased the cable or adapter to use with another device, can receive a refund from OnePlus as long as it is requested prior to December 31st. Because the accessories can be used safely with the OnePlus 2, the refund does not cover the parts that came in the box with the phone.
If you are eligible for a refund, click on the sourcelink which will take you to a form that you need to fill out to get your money back. Below, you will find a chart that lists the devices that can and cannot use the cable and adapter. As a rule of thumb, if your power bank, charger or USB hub has been certified by CE, CCC or UL, there shouldn't be a problem. But if you don't want to take any chances (and we can't blame you), requesting a refund is probably the safest course of action.
