45W 19.5V Dell laptop charger

This myVolts 3379 AC adapter delivers 45 watts at 19.5 volts and 2.31 amps for compatible Dell notebooks. It accepts 100 to 240 volt input at 50 to 60 hertz for worldwide use. The barrel connector measures 4.5 millimetres outer diameter by 3.0 millimetres inner diameter. The unit is supplied new and replaces Dell part numbers including LA45NM140 and HA45NM140.

For Dell Inspiron and XPS 13 owners with 4.5mm ports

Buyers whose Dell laptops list a 4.5mm by 3.0mm charging tip and require 45 watts at 19.5 volts will find this charger a direct match. The long compatibility roster covers many Inspiron 11, 13, 14, 15 and 17 models plus XPS 13 9333 9343 9350 and 9360. Users with Dell systems that need the larger 7.4mm by 5.0mm connector cannot use this adapter. Anyone needing a higher wattage supply such as 65 watts or 90 watts must look elsewhere.

Connector size 4.5mm by 3.0mm decides fit

The single specification that determines whether this charger works is the DC plug dimensions: 4.5 millimetres outer and 3.0 millimetres inner diameter. Dell uses two similar-looking barrel sizes across Inspiron 3000 5000 and 7000 series, so verifying the port on the laptop or the original adapter is essential before ordering. If the machine requires the 7.4mm by 5.0mm plug this unit will not connect.

Questions about this item

Does the 45 W adapter run hot or make noise when powering a laptop all day?

The unit delivers 19.5 V at 2.31 A from a 100-240 V input and has no fan, so it operates silently; warmth is normal for a 45 W supply under continuous load.

What must I already have for this charger to work with my Dell?

Your laptop needs a 4.5 mm outer by 3.0 mm inner barrel connector; check the port against the second product image before ordering.

Will this 3379 charger work alongside an older Dell 45 W brick I still use?

Yes, it matches the same 19.5 V 2.31 A output and 4.5x3.0 mm tip used on many Inspiron 3000, 5000 and 7000 models, so it can replace or supplement the original adapter.
