Great Product and Value for the money spent.
An excellent value on this unit which appears every bit O.E. and solved the intermittent non-charge issue we had with the original(less than a year old). If this can at least outlast the original I’ll come back and update accordingly.
I just received this product a few days ago and so far it is working out great. I am using it on my laptop. It was half the price of the one at a popular computer store. I am happy with it.
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.
it is not easy to get the right power adapter. Searched by model number and finally got this one. It is solid and good.
Searched many replacements for my laptop and found many that would work and less expensive BUT this by far is the best one! Great quality, looks very durable, and I prefer the way this charger is designed when I compare it to others. Sure I could purchase one less expensive (which I have in the past 6 months), and yep, it resulted in buying another due to is cheap quality. You really do get what you pay for. This charger is or at least looks to be a heavy duty one. The cord is heavy, the plug ins are designed to last, it look to be “quality”. Immediately began to work for my laptop upon plugging it in with NO error messages, no issues!
Great product and good buy.
This item is exactly as expected, bought as a replacement for a damaged cord. I’ve used it for several months now without any problems. I would certainly buy it again if the need arises.
Exactly what I needed! My laptop wasn’t charging and I was worried it was the laptop. I got it refurbished and I’m always weary of refurb electronics. I decided to try a new factory cord because the one that came with my laptop was not a OEM cord. It’s been working great! I hated to spend so much on a cord but I guess you get what you pay for!
My old cord started to wear in two. This new cord works fine and it does look exactly like the old one. I had always had trouble with a warning message that said my computer was plugged in but not charging. Now with the new cord, it is fully charged and I don’t get that warning message any more. I checked several places for prices and found this to be the best price. Very pleased.
Day one so I don’t know about how it will perform with future use. Fit my laptop great and works perfect. Thank you.
I bought two of these so that I can unplug and leave the AC adapter(s) at my desk either at home or work and still have one with my laptop. The item is as described by the seller arrived on time and both work very well
Excellent customer service,nice charger
Came on time and works good.
Exactly what I needed after my dog chewed my original charger.
Works well
I keep one adapter at work, one at home, and one in my backpack for coffee house work. Have learned the hard way that just because the cord fits into a laptop doesnt mean it should be connected. The difference in amps and watts is important to preserve the life of the battery. Worth the investment in the manufacturers adapter to protect the machine.
Great replacement or spare cord
This charger both powers the laptop and charges (so far) its battery. Some chargers (like another one I previously tried) will power the laptop but not charge its battery. Some will charge the battery for some period of time and then stop charging the battery (although they continue to power the laptop). If this charger stops charging the battery like it is now, I will update this review.
Good product but a bit long delivery time.
