90 W USB-C charger for Dell XPS and Latitude

This 90 W USB-C AC adapter delivers 20 V at up to 4.5 A to compatible Dell XPS, Latitude and Precision laptops. It accepts 100-240 V input at 50/60 Hz for worldwide use. The unit ships new with a barrel connector and a 2-pin North American plug. It replaces Dell part numbers OTDK33, LA90PM170 and DA90PM170.

Plug-in installation with fixed cable

Installation is a simple plug into the laptop USB-C port and a wall outlet; no drivers or configuration are required. The fixed cable means a damaged lead cannot be swapped without replacing the whole adapter. Users should verify their model appears in the supported list because some Dell systems need a different power profile.

Limited to USB-C Power Delivery profiles

The adapter negotiates 5 V, 9 V, 12 V, 15 V, 18 V and 20 V steps up to 90 W total. It cannot charge devices that demand higher voltages or proprietary barrel-pin signalling. Buyers who need more than 90 W or a detachable cable will need a different solution.

Questions about this item

How can I confirm the charger is delivering 20V at 4.5A after I plug it in?

The adapter label lists output profiles including 20V at 4.5A; a USB-C power meter inserted between the cable and laptop will show that voltage and current while the battery charges.

What comes in the box and is a USB-C cable included?

The package contains the 90W AC adapter with a fixed USB-C output cable and a detachable 2-pin North-American mains cord; no extra cable is required.

Should I choose the 65W or 90W version for a Latitude 7400 2-in-1?

The 90W model covers every listed Latitude including the 7400 2-in-1 and also supports XPS 15 and Precision 5530 that need the higher 85W output.
