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.
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!
Excellent, got two of these and they work really well with my computer.
I ordered two of these for laptop so that I don’t have to keep disconnecting the factory cable and charger when I move from room to room or travel. The products just arrived, and they look and, so far, work exactly like what came with the computer. I must admit that, at first, I wondered if these might be knock-offs; and I’ll re-post if something seems off. But again, so far, I’m all-around very impressed with the company and product.
Original was stolen in a burglary, but the laptop was left behind. Go figure. This replacement charger works perfectly, just as the original did.
I bought this when my original chargers wire was broken. Arrived fast.
Thank you. This AC charger solved my issue. I haven’t used my laptop for a few months, I thought it was junk. Turns out the old AC charger was shot. Might I add, this thig is good.. great quality, and longer cord than the OEM. Thanks again, you saved me from buying a new laptop.
The original adapter’s voltage started fluctuating, so it would not charge the laptop. This one is the correct replacement, unwrap, connect and works. No issues, no complaints.
Great power supply for my laptop. I wanted to have a second unit @ home. Works beautifully.
Day one so I don’t know about how it will perform with future use. Fit my laptop great and works perfect. Thank you.
Charges my laptop very quickly, which makes me very happy.
Works Perfectly! Great Price! I moved and somehow lost the charging power adapter. After searching, I found this unit and ordered it. Arrived in very sturdy packaging, opened the unit, plugged it in, and it charges great. Works just as the original unit did. The power unit has strong reinforced connections where the power and charging cables are attached – looks like it will hold up well to lots of wire flexing from packing and unpacking. Very Happy with My Selection!
Our computer was dying and we were afraid we’d have to buy a new one. Turns out it was the cord. This adapter was an instant fix and a savings of several hundred dollars.
I needed a replacement charger as my original one finally stopped working. I’m not sure if this is true OEM or not, but it works very well and is reasonably priced. I’ve had it for a few months without problem, so I don’t know it’s long term durability but so far so good.
Works as expected. Loved it.
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!
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.
It was reasonably priced, arrived on time, and works great. I would recommend this product to a friend.
Does what it says it does. I tried using other brands but nothing works like genuine. Can’t go wrong with this one.
Bought this for my husband who was sick of packing up his laptop cord every week to leave on the road for work. One for travel and one for home. Very nice.
