Only half as expensive as the original. Has same characteristics (Augang 5V, 2A - most USB adapters have only 1A). Funzt just as well for the new Note 10.1 (8010). Plug not hooked. Everything is wonderful.
Side note: as opposed to Tab2 invites the touch via USB. You only have to go down the score, otherwise it is recognized in the external hard drive mode from the PC and does not charge indeed. An extra USB adapter for charging so you can save, the original cable is sufficient.
So if a second AC adapter for the Note 10.1 look for: strong buy recommendation.
