Car Power Adapter for Dell Laptops

This 19.5 V car adapter powers compatible Dell laptops from a 12 V to 24 V vehicle socket. It delivers up to 90 W through a 7.4 mm by 5.0 mm barrel connector and includes an 18 W USB Quick Charge 3.0 port for phones or tablets. The unit suits drivers who need to run a laptop and charge a mobile device at the same time.

Practical Limits of the 12 V to 24 V Input

The adapter accepts a wide DC range found in cars, trucks, RVs, SUVs and buses, so voltage sag during engine start is tolerated. Output is fixed at 19.5 V with a maximum of 4.62 A, covering both 65 W and 90 W Dell models. The USB port is limited to 18 W and will not fast-charge devices that require higher USB Power Delivery profiles.

Build and Connector Implications

The 7.4 mm by 5.0 mm tip fits the listed Latitude, XPS, Precision, Vostro, Adamo, Studio and Inspiron models without an extra dongle. A single cable carries both the laptop and USB outputs, reducing clutter in the cabin. The adapter is not suitable for Dell models that use a different barrel size or a USB-C power input.

Questions about this item

Should I pick the 65 W or the 90 W version for my Dell?

This single adapter delivers up to 90 W and also works with 65 W Dell models; the 19.5 V 4.62 A output covers both ratings automatically.

What does the 19.5 V 4.62 A output mean when I plug it into my laptop?

It supplies 19.5 volts at up to 4.62 amps, providing the full 90 W your Dell expects and also matching older 3.34 A 65 W units.

How does the 12 V-24 V cigarette-lighter input limit what I can run?

The adapter accepts 12 V to 24 V from car, truck, RV or boat sockets, so it works across all those vehicles without extra converters.
