  • 19 V output matches the Samsung ATIV Book 7 NP740U3E requirement

  • Brand-new replacement adapter built for the NP740U3E series

Replacement charger for ATIV Book 7

This myVolts AC adapter is built as a direct replacement for the Samsung ATIV Book 7 NP740U3E and NP740U3E-K02US ultrabooks. It supplies 19V output and includes the mains power cord so the laptop can run and charge its battery from a single unit. The adapter is brand new and carries over-voltage, short-circuit and over-current protection.

Check connector and voltage before ordering

Verify that the original charger for your NP740U3E or NP740U3E-K02US also delivers 19V and uses the same barrel plug dimensions. Confirm the laptop's charging port is physically undamaged and that the mains socket in your region accepts the supplied cord or a standard IEC C7 lead. The adapter accepts 100-240VAC at 50/60Hz for worldwide use.

Replaces a lost or failing original charger

This unit replaces the factory Samsung power supply when it is lost, damaged or no longer holds a stable charge. The upgrade is worthwhile when the old adapter shows intermittent charging, overheats or its cable is frayed. It is not for buyers who need a higher-wattage brick for docking stations or discrete-GPU models that draw more power than the standard ultrabook design.
