Good product but a bit long delivery time.
Product was indeed genuine charger, as advertised. Works well, no problem. Bought as a second charger for home use, so the travel one can stay in the laptop bag ( got tired of needing the charger only to realize it had been left at home). There are many chargers available, this one was both the right model and lower price(-$12).
it is not easy to get the right power adapter. Searched by model number and finally got this one. It is solid and good.
The power supply doesn’t run hot. Quality seems good
After my brand new charger got chewed out by my feline nemesis, I was blessed to find this charger via Bing. Really happy with this product considering the competitive price.
My old power supply was getting dodgy and I found this one at a good price. Would purchase from this firm again.
I bought this as a second AC adapter for my laptop. Now I can charge at my desk or my recliner without having to move the power brick. This was much less expensive than through the official site and appears to be a genuine part matching my original brick.
They connect the PC but do not charge my battery
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.
I am very satisfied with the charger I received and the price is very affordable. This charger replaces my original charger. The original charger broke down after a period of time. This charger works the same way as my original charger. After using it for a period of time, I think this charger seems to be better than my original charger, and the price is lower than other chargers. I think this charger is perfect. I’m very satisfied with this shopping.
Works well
The product arrived as expected. I’ve used it one week and it has started from the git go to prove it works as a ORIGINAL power supply. Let’s put it this way. If it fails after a month or two, I will change my rating. But for now, it’s what I expected it to be and it arrived when it said it would. So far I am happy and I expect to stay happy. Like this 🙂
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.
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.
Arrived precisely on time. Item was in excellent condition upon arrival–plastic wrapped and pristine. The item is compatible with my computer. Charges my computer swiftly and the computer retains the charge. Highly recommended as a replacement charger!
This was exactly what I needed to replace an older charge cord with a broken end. Shipping was timely and it appears to be the real thing.
Replaced burnout old charger
No issues, been using for a month or so. Last charger kept coming up with warning on PC that it was wrong voltage, so I bought this. Expensive but operational.
I’m an electrical engineer and frequently help friends with their tech issues. I’ve recommended this item to many of my friends. My recommendations are based on 2 factors: quality and support. The quality of this charger is great. This vendor totally supports and stands behind the product – my issue was resolved immediately.
The first charger was faulty emailed them and a new one arrived a few days later no hastle good company would recommend them
