WAWEIS 19V 2.1A 40W laptop AC adapter

SKU CH-A0F0-EK39Q

19 V 2.1 A 40 W AC adapter with 10 ft cord and overload, over-voltage, short-circuit and overheat protection

  • World-wide 100-240 V input suits travel
  • 10 ft total cord length adds placement freedom
  • Over-current, over-voltage and short-circuit protection guard hardware
  • FCC, CE and RoHS certifications confirm safety compliance
  • 19 V 2.1 A 40 W output matches listed Samsung models

Compatible Samsung ATIV Book 2 models

This 19 V 2.1 A 40 W AC adapter is built as a direct replacement for Samsung ATIV Book 2 notebooks including the NT270E5V-KD2S, NT270E5V-KD3S, NT270E5V-K04IT, NT270E5V-K54S and NT270E5V-XD5S. It supplies the exact voltage and current those models require.

Upgrades from a lost or faulty original charger

The unit replaces an original Samsung charger that has been lost, damaged or no longer holds a stable output. The jump is worth it when the old adapter shows intermittent charging, overheating or a frayed cable that could harm the laptop.

Steady output with full protection suite

Over-current, over-voltage, short-circuit and total-power protection circuits engage instantly under sustained load, while the smart chip manages overheating risk. A 10 ft power cord and 100–240 V 50/60 Hz input keep delivery stable during extended use.
