This Adapter is so great my dog decided to snack on it. We ordered another right away and were very pleased with the performance of both. The second we are keeping far from the dog's reach. excellent products and services.
Good Quality charge cable. No complaint, fit my Asus Q302LA-BBI5T14 laptop perfectly.
The product description was very helpful. Thanks to electronicscrazy.sg for the fast delivery at my doorstep. Thanks
The Charger was a gift for my wife, so I have no actual useful information that I can provide on which to base this review. She uses this computer very rarely, but I have heard no complaints from her that she has encountered any problems.
The product worked perfectly on my Asus laptop. Charged it as indicated. The great price arrived in a timely fashion. No problems are very satisfied with this item.
This charger purchased for my Son's Asus computer and worked perfectly! What a great deal!
My old charger went out on my laptop and replaced it with this one and it works great!
It is working non stop on an overused laptop for almost two straight months. No faults, no fires, just solid charging going on.
I purchased it as a replacement for my Asus charger. I’ve had it for about a couple of months now and it still functioning properly. Would definitely recommend it. It does feel a little less durable than the actual Asus Taichi 21 charger but it does the job.
Next day delivery after ordering very late in the day, impressive, reasonably priced and so far so good, working well would recommend.
