Google engineer says you shouldn’t buy OnePlus USB Type-C cables

Leung adds that this won't have an affect on the OnePlus 2 itself as the handset doesn't support Type-C fast charging, and that the warning is more for owners of the Type-C compliant Nexus 6P, Nexus 5X, and Chromebook Pixel. "However, it's still not cool to keep that cable around because the next phone or tablet or laptop computer you buy might support 3A fast charging, and if you forget that cable is bad, you may damage a charger sometime in the future," says Leung. "If you want to keep the cable, mark it with a tag so you don't forget it's special." But not special in a good way.

hmmm... first rumour/ render already out for OnePlus 3...
