I have bought a lot of things from Woot and this is the first time I have been disappointed. Bottom line, this item does not output put 2.1 amps! It is labeled as such but only outputs 1 amp. Very disappointing, this will make me think twice before buying in the future.
Oh man, sorry. Please email firstname.lastname@example.org with your order details and issue; CS can help get things taken care of.
