SKU CH-4JJV-N5QAG

180 W AC adapter delivering 19.5 V at 9.23 A through a 5.5×2.5 mm plug for compatible laptops

  • Delivers 180 W for demanding laptop workloads
  • 5 V 9.23 A output matches original charger specs

  • 100–240 V 50–60 Hz input works worldwide with included cord
  • CE certified for electrical safety compliance

Purpose & Fit

This 180 W AC adapter replaces the original charger for Eluktronics MAG-15, Evoo EG-LP5-BK and Tongfang XNE15E19 laptops. It delivers 19.5 V at 9.23 A through a 5.5 × 2.5 mm barrel connector. The unit accepts 100-240 V input at 50-60 Hz and includes a matching power cord.

Thermals, Noise & Power

The adapter is rated for 180 W continuous output and meets CE certification requirements. It operates from a universal 100-240 V supply without a voltage switch. No fan is present, so the unit runs silently; heat is dissipated through the case during normal charging loads.

Upgrade Context

This unit is a direct replacement for a lost or damaged FSP180-AJBN3 brick. It is not suitable for laptops that require a different voltage, current or connector size. Buyers needing higher wattage or a USB-C power delivery interface should look elsewhere.

Questions about this item

How do I connect the 5.5x2.5mm plug and avoid the polarity mistake?

Match the 5.5 mm outer and 2.5 mm inner dimensions to the laptop port, then confirm the tip is positive before inserting; the adapter delivers 19.5 V at 9.23 A once seated.

Which part will wear out first and need replacing?

The detachable mains cord and the DC cable near the 5.5x2.5 mm connector are the items most likely to fatigue after repeated flexing.

At what point does the 180 W limit throttle sustained output?

Continuous draw at 19.5 V and 9.23 A reaches the 180 W ceiling, so the unit will protect itself if the load tries to exceed that power level.
