Charges my laptop very quickly, which makes me very happy.
They connect the PC but do not charge my battery
The first charger was faulty emailed them and a new one arrived a few days later no hastle good company would recommend them
Perfect for my laptop. Had to replace the one that came with it originally. Works perfectly
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..
This adapter is exactly as advertised but a bit better. It is slim and lightweight. It was easy to install with no questions. It was easy easy and worked with no problems. The seller sent the adapter securely without question of it’s arriving safely and with all cables included and the transaction went smooth as silk. If only every purchase was this easy. I will buy from this dependable seller again.
It is a very good charger, looks good and high quality
Works as expected. Loved it.
Great replacement or spare cord
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.
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.
I plugged it in and it started charging. That is all I needed it to do.
Great chargers at wholesale price, what’s more, my customers are happy.
My original power cord stopped working. I bought this one for my laptop. It works great just like the original did when I first got the laptop
Fit like it was made to, and now my computer is functional again THANK YOU.
Exactly as the factory original.
As often, wide range of pricing for items. Seems to be OEM and works perfectly. Better than the one supplied with the computer in that the AC cord fits very tightly and is longer than the one shipped with the comptuer.
Very happy with this purchase. I needed to replace the factory charger that came with my laptop after it shorted out, and this is the perfect replacement. It’s durable, and a great value for the money I paid for it. Definitely recommend!
Great power supply for my laptop. I wanted to have a second unit @ home. Works beautifully.
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!
