Hi people,

 

I need help concerning the adapter, since all 135w acer adapters i've seen come with only

a few compatible models listed, and is hard to believe that they work *only* with these laptops.

Concretely, should this adapters: https://store.acer.com/en-us/ak-135ap-010

also work with VN7-792G, not only with VN7-791G?

And should adapters listed as compatible with VN7-591G work with VN7-792G?

 

thank you

    Hello,

     

    The AC adapters of 135W have the same specifications for the following models:

    • Aspire VN7-591G
    • Aspire VN7-791G
    • Aspire VN7-792G

    Specifications:

    • 135W - 19VDC - Tip dimensions (mm): 1.7x5.5x11

    Well, the above information is incorrect.

    I bought 791G adapter:

    https://www.amazon.co.uk/135W-Adapter-Aspire-Nitro-VN7-791G-76Q2/dp/B00XVRVYXG/ref=sr_1_1?ie=UTF8&qid=1465491429&sr=8-1&keywords=135W+AC+Adapter+For+Acer+Aspire+V+Nitro+VN7-791G-76Q2

    In part because acer sells liteon adapters in its own web shop.

    But, it does not work, ie the laptop (792G) does not charge.

    Its a shame that Acer cannot provide detailed specification for the

    compatibility of the adapters.

    Hello,

     

    The seller made a big mistake because:

    135W AC Adapter For Acer Aspire V Nitro VN7-791G-76Q2 (tip specifications of VN7-791G (mm): 1.7X5.5X11)

     

    We are Dispatching Genuine High Quality Liteon Adapters as shown in the PICTURE for use with laptops This has a 5.5MM x 2.5MM Connector Pin Size - TO BE USED WITH LISTED LAPTOP MODELS ONLY PLEASE DO NOT PURCHASE BASED ON PART NUMBERS PLEASE CHECK THE PICTURE; PART NUMBERS CAN BE SIMILAR WITH DIFFERENT PIN SIZES.

     

    That can't work. 2.5mm instead of 1.7mm! My information is correct.

    Hi,

     

    Well it seems it can work, for example, here it says its 2.5x5.5:

    http://www.aceronline.es/ac-adapter-cargador-original-135w-acer-aspire-nitro-vn7-591g-vn7-791g-series-kp-13503-004.html

     

    The vendor on amazon is AJparts and they have pretty good reviews, so I would

    say they know what they're selling. Do you have some link with specs that show 791g is

    compatible with 792g, ie 1.7x5.5?

     

    Also, big shoutout to Acer, it is brilliant engineering to make adapter *pins*

    for two almost identical models incompatible. I'm impressed.

    Hi,

     

    What does that mean? These are not references, these are tables than I could

    also write with any data in it. From this I finally conclude you gave wrong information.

    But that is not that bad, I'm also responsible for believing it because really

    it sounded logical and I think Acer is also quite responsible for

    not providing specifications such as tip sizes in their laptop documentation.

    I will in time sell 791 adapter for sure, and in a week buy the right one. Cheers.

    First column shows the Acer part numbers.

     

    I'm not an Acer employee. I'm just a member like you.
