Question: Is this adapter compatible with ASUS Zenbook UX301LA-XH72T 13.3-Inch Touchscreen Ultrabook?
Document: This is the *exact* same version you get when you buy your ultrabook, in my case a ASUS Zenbook UX32VD-DB71. I damaged my 65w OEM adapter that came with my ultrabook and all other replacements were too big, bulky, or have interchangeable tips that were too easy to lose .The OEM version is compact and fits perfectly. You cannot order from Asus easily - so this find was perfect.
The power adapter that I received is not the one shown in the pictures and not the same one I received with my laptop (ux301 zenbook). However the plug is the same and the voltage and current rating are the same. Seems to work fine so far. I think this may just be an older version of it. It is however an ASUS OEM supply which is what I was hoping for. I didn't want to trust my nice new ultrabook with an after market supply.
I am highly satisfied with the purchase. Initially I received the adapter for a normal ASUS laptop which did not work for my Ultra zenbook. I was allowed to exchange for the right one after I provided details specification of the required adapter.
It's an original ASUS charger, which is what I was looking for, and it works perfectly. It's a bit larger than the one that came with my ultrabook, but not large enough to be an inconvenience.
This particular adaptor is for the ASUS UX31A, NOT the UX31E. The description did say that but I didn't realize until I got it that I have the UX31E. Check your ultrabook carefully to figure out if this is the right adaptor. The model number is on the bottom/back of the computer in the smallest letters/numbers possible.
Besides it is larger and heavier than the original power adapter that comes with UX31A Ultrabook, it works perfectly fine. Charges it quicker. Excellent choice!
This power supply is an Asus OEM power supply for the Zenbook. It is larger than the one that comes with the laptop, but is the exact same power supply as you will get if you order an extra power supply from Asus when you purchase the Zenbook. It is about 3&#34; square, and 1&#34; high versus the 2.5&#34; square by 1&#34; high original that comes with the Zenbook.
This one is almost 3&#34; square by the same thickness. My original adapter has fixed AC prongs, the prongs on this one fold down into slots. Because it is bigger and can supply more power, it seems to run a little cooler than the original.
IMPORTANT PIECE OF INFORMATION: it says on the box that it is compatible with 12" and 13" UX series (UX21A, UX31a, UX32A, UX32VD) *Not suitable for UX21E and UX21E. So this charger is safe for anyone with the previously mentioned modelsThe charger works great (probably looks better than the OEM one). There is a LED ring around the plug (rather than the dot from the OEM one) which looks more premium than the LED dot.
I like it as it's a good power supply, but it's not perfect because it's about 40-50% larger than the power supply that came with my ASUS Zenbook.
Answer: ASUS support told me that only a 45w adapter should be used to ensure no motherboard damage on UX301LA models.
