135W AC Adapter Laptop Charger for HP 391174-001 384023 481420-001; HP DC7800 DC7900; HP Compaq Elite 8000 8200 8300 with Size 7.4mm 5.0mm Power Supply Cord Plug

After a storm and power reset I lost all power to my computer. I work from home so this caused me to loose money. Bought this off Amazon, it arrived in 1 day pluged it in and voila! Worked beautifully now I'm up and running again. If it matches your specs save yourself the stress and (having to watch 20 YouTube videos on how to fix a computer that wont power on) and just go ahead and order it!

Our puppy chewed through the cord of my old laptop charger. This one does the job just fine. I have not measured voltage or any other parameter but can report that, when plugged into 120V and into my HP desktop computer it has done the job.

Perfect fit for HP AOI. 1/2 the price of HP replacement.Original HP power supply of 95 w. But this is rated at 135 w. Maybe the power mod would run cooler.

Works on all of my equipment.Some devices require less amperage at the same voltage, but it is more than OK to over rate the power supply, since that makes the power supply and equipment last longer and neither has to struggle with not having enough.Perhaps the seller should mention this in order to boost their sales? It would certainly help those with less electronics know-how. :-)

Bought a cheap HP desktop and couldnt get it turn on, and finally this unit resolved the issues of it turning on, block stayed relatively cool after some good use. Long cord on both ends, and so far a few weeks in no issues with it

I got to replace the power supply on an HP Elite 8300 small desktop PC. It's working as it should and after hours of use it remains cool. Now for the test of time but so far so good.

Worked

Product works great! Instructions were very clear how to use the device! Very satisfied doing business with Amazon!!!
