  • Battery TypeLithium-Ion
  • Delivers 90W or 65W power for demanding workloads
  • Works with Dell Latitude models from D400 to E7450

90W and 65W dual-output adapter

The GCROWN adapter delivers 19.5V at 4.62A for 90W or 3.34A for 65W, matching the power profiles of many Dell Latitude models. It accepts 100-240V input at 50/60Hz for worldwide use. The 7.4mm by 5.0mm barrel connector fits the listed Latitude families. The unit is new and carries CE, FCC and ROHS certifications.

Steady output under continuous load

Rated for 90W maximum, the adapter maintains its 19.5V output during prolonged charging sessions without dropping to a lower wattage mode. The 65W compatibility means it also serves systems that draw less current while keeping voltage stable. Certification testing confirms compliance with safety limits for sustained operation. No thermal-throttling behaviour is specified in the data.

Verify connector and part number first

Confirm that the laptop uses a 7.4mm by 5.0mm barrel tip before ordering. Cross-reference the device’s original part number against the compatible list such as PA10, DA90PE1-00 or 310-2862. Ensure the required input voltage range covers your local mains supply. Buyers needing a different tip size or a higher wattage rating should look elsewhere.

What must I already own to use this 7.4*5.0mm charger?

You need a Dell Latitude model that accepts a 7.4mm by 5.0mm barrel connector and requires 19.5V input, such as the Latitude E5440, E5450, E5530, E5540, E5550, E6220, E6230, E6320, E6330, E6400, E6410, E6420, E6430, E6440, E6500, E6510, E6520, E6530, E6540, E7240, E7250, E7440 or E7450.

Will this 90W unit work alongside my older 65W Dell PA-10 brick?

Yes, the adapter is rated for both 90W (19.5V 4.62A) and 65W (19.5V 3.34A) operation and lists PA-10 and PA-12 among its compatible part numbers, so it can replace either brick on supported Latitude models.
