Bought as a spare to keep in my laptop case for when I’m Working out of other offices. And it's worth the price and it's a durable product. I would recommend to everyone if they are looking for a replacement or a spare.
Suits and fits for my laptop and I am pretty sure about its compatibility with other laptops as well. A must-have universal laptop adapter. Coming to charging it charges very good and doesn't get heated much and also the output voltage is regulated automatically. Those who wanna buy it go buy it without a second thought.
The charger worked perfectly for my daughter's ZenBook. The original wasn't up to the challenge of use by youngsters and this was a cost-effective way to put it back in service. As advertised and available for quick delivery.
Quality is good for working perfectly. I'm using for 3 months without facing any issues
Work great, well made. Only had them about a week but so far so good. No overheating even with plugged in at the same time.No complaints as a shopper. The product was delivered fast and it works just as expected
This is a great deal. You get a high-speed, charger for a fraction of the in-store price. I have found this charger gets my Laptop charged much faster than the random off-brand cord and plug I was using before.
