This is NOT OEM, for anyone thinking they're getting a great deal. Despite the knockoff's best attempt, it's quite easy to compare the OEM charger to this one and see that it isn't the real deal.This charger is noticeably slower than the OEM charger, but I am only using it to sustain my phone during the day at my office desk, so it's not a huge deal to me. Beats lugging around the original charger here, there and everywhere.A couple of things for those concerned: 1) this is not UL listed. I doubt it will burn your house down any time soon, but if you're a stickler for that sort of thing, steer clear2) Despite the cord being blue-tipped, I have my doubts that this is USB 3.0..and 3) though the packaging says 2.0A, it charges slow enough that I feel that claim is a little dubious. After all, if this company can lie and pass knockoffs as OEM, what else are they fibbing about?
