Compatible Dell 45W power adapter

This genuine Dell LA45NM140 adapter delivers 45 watts at 19.5 volts and 2.31 amps for compatible Dell laptops. It includes a detachable power cord for immediate use. The unit accepts a wide 100-240 volt input range at 50-60 hertz, making it suitable for international travel. Buyers needing a higher wattage unit for larger workstations should verify their device requirements before ordering.

Sustained 45W output with protection circuits

The adapter maintains its rated 45W output continuously thanks to built-in safeguards against incorrect voltage, short circuit and internal overheating. Each unit is tested for wire integrity, jack function and internal debris to ensure reliable long-term operation. Minor cosmetic marks on the casing do not affect thermal or electrical performance. Users running sustained heavy workloads can rely on the protection features to prevent adapter shutdown.

Check laptop port and voltage match

Confirm your laptop requires exactly 19.5V at 2.31A and uses a compatible barrel connector before purchase. The 100-240V input covers most global mains supplies without a voltage converter. Ensure the included power cord matches your local wall socket or source a suitable replacement. Devices requiring more than 45W will not charge correctly with this adapter.

Questions about this item

Does the 45 W 19.5 V output run hot or make noise when left plugged in all day?

The 45 W 19.5 V 2.31 A adapter has no moving parts and is tested for internal overheating protection, so it stays quiet and only warms slightly under continuous load.

What must I already own to use this 100-240 V 1.3 A input brick?

You need a Dell laptop that accepts a 19.5 V 2.31 A barrel connector and a standard C5 clover-leaf mains lead for the included power cord.

Can this 45 W unit safely replace the original charger on an older Dell that came with a lower-wattage power supply?

Yes, the 45 W 19.5 V 2.31 A output matches the voltage and meets or exceeds the current of smaller Dell bricks, and the built-in safeguards prevent incorrect voltage or short-circuit issues.
