Genuine Original OEM 90w for Dell 0RT74M RT74M PA-1900-32D5 AC Adapter Exact 19.5v 4.62a

Oem product. Worked perfectly.

Failed to charge my laptop. The light on the block would not even come on. Maybe it was a dud, but I would recommend buying directly from the manufacturer.

OEM charger and non OEM battery does work, i love finding a way around Dells road block. DO MAKE SURE that the mili amp hour AND the voltage rating of both charger and battery.

Bought this to replace a bad power supply for my sons Dell AIO computer. It is half the price here than what Dell is charging and it works perfectly. What more can you ask for?

The AC adapter works perfectly so far, appears to be identical to the original. The original lasted 5 years, no way to know about this one.

Good

...the neighbor was nice and brought it to my house. This is exactly like the original! I needed an extra charger for use in a different part of the house or for work travel.

This was just what I needed. But, be sure to double check the volts and watts before ordering.

These adapters are intended for certain Dell OptiPlex desktop computers that have the ability to run on a low-wattage 65w or higher-wattage 90w adapter. The PCs (bought used) came with the 65w adapters which cause the machines to run in an extremely-slow low power mode (800Mhz, about 25% speed). This 90w adapter, bought as a replacement, completely resolved the issue and the machine is back to its full performance at 2.9Ghz.

Wanted to leave a charger at the office and bring my laptop home to a dedicated home charger, this does the job.
