I recently bought a used Samsung Galaxy Note 10.1 2014 Edition but it did not come with a charger/usb cable. Im not exactly sure which one I need for it, volts/amps. I see a lot of knockoffs on ebay and amazon that have sorry reviews and not sure which ones are really OEM or will at least function as they should for this tablet. Anyone know where I can get an OEM or one that will charge correctly? Thanks.
