  1. If you’re experiencing a failure to charge your computer, look at the battery of your computer or the back panel. It should tell you what amount of current is needed to charge the battery. Don’t just look at the manual. Best part is that even though I informed customer service of my error they let me keep the new replacement charger. So the product overall works great once I used the correct head and checked the current needed to charge my computer. Since there may be multiple heads that are the same that fits your charging port of the computer but will not provide sufficient current to charge your computer or may provide too much that could damage it.

  2. Replaced burnout old charger

  3. It was described and arrived on time

  4. Works well

  5. 2 previous cheaper ones I ordered would not work with my laptop, even though seller said they would. They would power unit but not charge battery, It would get “charger not recognized” message even though they claimed to be the correct chargers. This one cost more but it works.

  6. It’s nice to have a second power supply so I don’t have to get behind furniture and unplug it every time I want to take my laptop to a different floor of the house for more than a couple hours. It’s literally exactly the same as the cord that came with it.A bit pricey, but then again, I know it won’t melt my laptop or start a fire or something.

  7. I needed a second AC adapter for my laptop when our ‘work from home’ guideline at work became a ‘work from home sometimes’ edict. Being lazy, I figured having one power brick (adapter) at home and another one at work would mean I’d not be lugging one around and crawling under my desk to get it running when I was there. It was a good choice and the one I ordered (twin of the one that came with my laptop) was priced right and arrived early, so what’s not to like?

  8. The second order of 80 adapters came on time. Thank you!

  9. Great Product and Value for the money spent.

  10. Bought 60 adapters for my company. Arrived quickly and they work great. Recommend! Will place a second order of 80 adapters soon

  11. I needed an extra charger for my laptop and this for sure came in clutch and works AMAZINGLY !!! Good quality and it charges my laptop pretty fast..faster than my original laptop charger!! This charger will most definitely become my primary charger that I use daily . I needed this badly since i bring my laptop everywhere and only had one charger & shipping was pretty fast as well ! Would definitely recommend anyone to purchase this..

  12. This product replaced the original charger to perfection. It came rapidly from the shipper and seems to be very well built and flexible to avoid wear and tear. we have had this in use for quite some time and it fits the bill. I Give the experience a 5 thumbs up.

  13. This worked perfectly for my PC. I was unable to turn on it for months. At first thinking it was my battery, I bought a new battery and it still didn’t work. I wasn’t sure this specific adaptor would work because my PC is no longer being manufactured. But it turns out it was a perfect fit.

  14. My laptop was always iffy on wanting to charge when plugged in,
    which when on for a few months before it decided on not wanting to charge at all. It would then only work when it was plugged in. I eventually realized that it was the charger and that it needed to be replaced. I had the original one from purchasing my laptop about one year ago. Hoping this one lasts for that long if not longer as well.

  15. I am so happy I finally got this charger. If you ever get your battery run down and have trouble charging, don’t spend years “baby-ing” your old charger by trying to change walls to plug into. This is what was recommended and worked for a time – but totally miserable. This charger worked quickly and made me so happy!! This is a good product. Get a new battery at the same time if you are worried.

  16. Built well, and works perfectly. I see no functional differences between this power supply and the OEM that came with the laptop. I was skeptical because the price was so low, but I was pleasantly surprised by the quality. I’d recommend this product to friends and family without hesitation!

  17. The charger arrived as promised. It got my laptop up and running and charging was completed as I expected. I feel confident getting this charger as opposed to a compatible charger that came with my refurbished computer.

  18. It is a very good charger, looks good and high quality

  19. Does what it says it does. I tried using other brands but nothing works like genuine. Can’t go wrong with this one.

  20. I bought this item for my laptop because my other cord has been compromised and didn’t charge anymore (without massive amounts of electrical tape holding it together until this product arrived). As soon as it arrived, I pulled it out, plugged in it and have had power ever since. Not sure what else to say about an electical cord, but it works great, was brand new and in perfect shape. I had looked around locally and could not find this exact part and it was much more expensive from the manufacturer and a lot more trouble to purchase. So, I ordered this one, had it in a week and am very happy with it.
