Replacement car charger for Samsung NP940X3G

This 19V 45W inverter plugs into a 12V or 24V vehicle socket and powers compatible Samsung laptops. It replaces 30W, 40W, 60W and 65W original adapters. The right-angle DC jack reduces strain on the laptop port and the long cord reaches rear seats easily. Short-circuit and over-temperature protection are built in.

Suits drivers charging a listed Samsung notebook

Buyers needing AC wall charging or a different output voltage should choose another product. The adapter only works with the specific NP940X3G series models named by the supplier. It cannot power devices that require more than 45W or a non-19V input.

19V 45W maximum output from 12-24V DC input

The unit delivers 19VDC at 2.1A to 3.42A, peaking at 45W. This single figure determines whether your Samsung laptop will charge correctly in the vehicle. Always confirm your device matches the listed model numbers before purchase.

Questions about this item

What size 12V outlet clearance does the 3.94" x 1.57" x 1.18" adapter need?

The unit measures 3.94 by 1.57 by 1.18 inches and weighs 8.7 oz, so it fits standard cigarette lighter sockets with a few centimetres of free space around the body.

How do I connect the right angle DC plug without stressing the laptop jack?

Align the 90 degree elbow with the port, push straight in until seated, then route the long cord so the connector cannot be pulled sideways.

When should I replace the internal fuse after a short circuit event?

The built in protection handles short circuit and over temperature automatically; if the LED indicator stays off after a fault, replace the whole adapter.
