IF charger does not have a output of 2100ma (2,1 amps) its going to take forever to charge unit, typically the beauty chargers (cheap & colorful) only put out about 600 to 1000ma ( .6 to 1 amp) and and are only for cell phones, bet you will have the dreaded red "X" over battery charge indicator when you are plugged into this charger when ever unit is on...
IF you need longer cord, put extension on wall wart, err "charger"....
You might get away with just using just the cord with Samsung provided power adapter IF wire gauge (wire size) in cord is large enough... Then again do not be surprised if you get the "X"...
