Exactly as the factory original.
I purchased a cheap imitation earlier from another site… needless to day it did NOT work! The one I purchased here works just like the original one did! Very happy with it.
Left my power cord at a coffee shop I was working in. Thought I would just go to a big box and pick up a new one . Wrong.!!! They wanted too much. So checked online and I found one that had the right adapter . So far it has been great. It charged my laptop just as fast as my old one and keeps a charge going while I’m using it. No difference at all from the old one. I have only had for a little while , but for the price compared to the big box I can buy three more for the same price if I need to. Before you buy make sure the adapter is the right size for your computer.
Well I was pleasantly surprised when I plugged in my new AC power supply and my slow internet and non-charging battery came to life! I had lost my original charger for my laptop so I bought a cheap replacement charger but little did I realize that the imitation charger would slow down my internet to a crawl as well as not charge my battery. This charger fixed both issues! I found out online that some imitation chargers have a smaller dimple that causes all sorts of issues and will not charge your battery. I am so glad I did not buy a wifi card or reinstall my operating system for a second time before discovering this charger. Thank you for saving me a lot of money and time, not to mention my nerves lol!
My daughter lost the charger for her laptop and this is excellent. It came fast and fits perfectly.
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.
It was reasonably priced, arrived on time, and works great. I would recommend this product to a friend.
I plugged it in and it started charging. That is all I needed it to do.
Two Thumbs Up.
I was having a problem with my battery showing plugged in but not charging. Was using a charger that was not original. Had read that the charger could be the problem and my computer was also running slow. Well, what do you know? I purchased this charger and my computer is running faster and now my new battery is charging. Fixed my problem that drove me for a week. Glad I purchased this and it was half the price the official site wanted.
Excellent, got two of these and they work really well with my computer.
Works well, lasts. I run an IT department and we depend on these when people’s adapters stop working. We have ordered several of these also as “travel cords” so people don’t have to remove them from their office wall sockets every time they go anywhere. A+
Needed a new cord as puppy chewed up the original one. Quick delivery and works perfect.
This AC adapter is a great additional charger for my notebook. Seller shipped the correct charger quickly. I’ve only used it a couple of times so far and it charges my notebook quickly.
Great Product and Value for the money spent.
Perfect for my laptop. Had to replace the one that came with it originally. Works perfectly
I lost my charger for my laptop and I needed a new one asap because I need my laptop for school. I found this one which is a reasonable price. It charges my laptop with no problems. It seems pretty durable. And came with a variety of sizes. So far so good.
Replaced original with no problem.Have used it for a couple months with no issues.
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.
My original laptop adapter quit working and this is a great replacement.
