Genuine Dell 90W 7.4mm AC adapter
This genuine Dell AC adapter delivers 90W at 19.5V 4.62A through a 7.4mm barrel connector. It suits owners of compatible Dell laptops that require this specific voltage and tip size. The unit accepts 100-240V input at 50-60Hz for worldwide use. Buyers needing a different wattage or connector diameter cannot use this model.
Included power cord and tested reliability
A detachable power cord is supplied so the adapter is ready to plug into any standard mains socket. Each unit is tested for correct output, intact wiring and a firm jack fit before dispatch. The housing may show minor cosmetic marks that do not affect operation. No extra cables, tips or software are bundled with the adapter.
90W output limit and fixed 7.4mm tip
The adapter provides a maximum of 90W; systems that draw more power will not run correctly from this unit. The 7.4mm barrel is not interchangeable, so laptops with a different pin size or USB-C charging port are incompatible. Input frequency is limited to 50-60Hz, which covers typical mains supplies worldwide.

Questions about this item
Does the 7.4 mm barrel connector on the LA90PE1-01 wear out and need replacing?
The 7.4 mm connector is tested for proper contact before shipping; no user-replaceable parts are specified.
What limits continuous output at 90 W on this adapter?
The 19.5 V 4.62 A rating sets the maximum sustained output; internal overheating protection will throttle if that limit is exceeded.
How much heat and fan noise does the 90 W unit produce when running all day?
No fan is fitted; the adapter relies on passive cooling, so it runs silently and warmth depends on load and airflow.
