Asus Zenbook UX305 / UX305FA review – the fanless ultraportable

    Hello Andrei Girbea:

    I am planning to purchase a portable SSD laptop mainly to use for work which includes working on multiple excel spreadsheets containing huge number of rows (over 20,000) and advanced formulas. I usually have 5-10 spreadsheets open at once. I really like this Zenbook UX305 because of its specs and an attractive price of $700. However, I am wondering if it will be able to handle my needs working with the spreadsheets as I mentioned above. My other choice is Dell XPS13 which I think can handle the spreadsheets due to a more powerful processor however, it’s also $300-$400 more.

    I would appreciate if someone can tell me if Zenbook UX305 will be sufficient for my needs. Thanks.

      HI James. I’d probably not get the UX305 in this case. Something with an i5 CPU and 8 GB of RAM would be faster, and even so, loading those files at start might take a while.

      However, I’m not very familiar with such huge excels, thus the UX305 might actually handle them better than I give it credit for. You can try to get one from a solid source like Amazon or Micrososft Store and then return/replace it with the XPS in case it’s not good enough. However, from what I’ve seen the UX305 is no longer in stock for $699, but for $799, which gets it a lot closer to the XPS 13 (you can buy one for around $850 with Student Discounts from Microsoft Store).

    Hey Andrei,

    Thanks for this great review! It is really helpful.

    I have a question, and would appreciate your help:
    I am in the market for an ultrabook. I first decided to buy Macbook Air, but UX 305 looks like a great deal. My main concern is its Core-M processor. I am a graduate student who is mostly using statistical computing softwares (such as R, STATA, etc.) and document preparation software (such as LATEX). Would UX305 be a good choice for me? I wonder whether a Core-M device can handle these tasks.

    And also, do you have any idea that the next generation MB Air will use the same processor as UX 305?


    • Andrei Girbea

      February 25, 2015 at 6:11 pm

      Hi Mark. I’m not familiar with those pieces of software, so can’t tell how well they are going to run on this Core M platform.

      Also not sure about the MB Air. There’s a fair chance the Retina MBA 12 will be powered by Core M, but we’ll have to wait and see.

      LaTeX should be no problem, if you don’t compile every minute.

      How long do your statistical problems run? Seconds, minutes, hours?

      • Mark D

        March 11, 2015 at 12:01 am

        Thanks Andrei and thanks Ben.

        As to Ben’s question, my stat programs run usually 5-10 secs. I hope it will not be a problem with UX 305.

        Actually, I was waiting for new Mac, but as it was announced yesterdat, it is well above my budget ($1000) (also single port doesn’t make sense).

        Now, I am in between two ultrabooks: Asus UX305 and MBA 13. Andrei, which one should I buy?

        I like the specs and price of UX305, but I am just worried about Win OS. I have been a Win OS user for five years, and I restore the system almost every year due to some ridiculous crashes. That is why I am thinking about MBA 13, although the price is higher.

        I would appreciate your suggestions.

      • Andrei Girbea

        March 12, 2015 at 12:12 pm

        Different kinds of laptops imo. The UX305 is not as powerful, but somewhat thinner and lighter, plus has a better screen (matte) and fanless hardware.

        The MBA 13 is built on U series hardware, thus is faster, lasts longer on a charge, but is significantly more expensive for a similar config. For everyday use, I think the UX305 is a better deal, but don’t expect it to be very fast with multitasking.

      • Tobbe

        March 12, 2015 at 12:22 pm

        I read somewhere that todays Core-M laptops are comparable in performance to a top-of-the-line laptop from 2012.

        So if whatever you want to do is working fine on an older computer, it will still work at least as good on for example the UX305

      • Ben Sisko

        March 12, 2015 at 6:39 pm

        Your stats programmes shouldn’t be much of a problem then. At least if you don’t mind some extra seconds, depending on the hardware your current 5-10 seconds are measured on.

    I use my laptop for MS office, web browsing, watching HD videos/movies, listening to music, and MATLAB (mostly programs that run for a short amount of time)

    Would you recommend the Zenbook UX305?(

    If not, which of the following two laptops would you pick:

    • Andrei Girbea

      March 12, 2015 at 12:06 pm

      Matlab might kill the UX305 for you, but everything else should run fine. Can’t say for sure though, I haven’t used Matlab in many years. Still, if you don’t mind waiting and those projects are indeed small, it might be the better pick anyway.

      • Ben Sisko

        March 12, 2015 at 6:41 pm

        Same as in the last comment applies here for Matlab.

  4. Spede

    March 13, 2015 at 12:07 am

    In France for 700€ we get HALF the specs… what the hell, man?

    Normally for a thing that costs 700USD we can get the *exact same* for 700€. See, we already lose here, because with the conversion rate the laptop could actually be cheaper than 700€.
    But I’m not complaining about that. This is the price of welfare.

    The issue here is that not only do we lose on the conversion rate, which is basically the norm, but we get WORSE specs for that money!
    That’s insane. No way I’d buy that laptop here with such price.

    • Chris

      March 13, 2015 at 9:53 am

      Yes, same here (Greece). 700 dollars would be 800 euro here, not even 700 euros (still more than 700 euros) but with worse specs. Outrageous.

      • Ben Sisko

        March 13, 2015 at 2:37 pm

        Just saying, those comparisons usually ignore that US prices are usually stated before tax, European usually are after tax. Didn’t check how it is here.

      • Andrei Girbea

        March 14, 2015 at 9:15 am

        yes, the US prices mentioned here are before TAX.

    • Bernard

      March 22, 2015 at 8:25 am

      Same in the Netherlands, Half the specs and totally overpriced euro 750,00 for a brown choclate machine which looks like a toy.

  5. David

    March 13, 2015 at 4:18 pm

    I am french, they apply the exchange rate 1 to 1 between Euro and Dollar, and they add 19,6 % VAT on it that’s simple.
    So to do that without increasing the price they drop by half RAM to 4Gb end SSD storage to 128 Gb…
    But I found and buy today the best model just below 900€ so maybe for 550 you’ll find something on e-merchant discounters.

    hey andrei, great review, i need a computer with a very bright screen for my eyes problem.
    is this one has it, or can you advise me about a model with brigther one.
    i had the lenovo u430p and it was too dark for me.

    thanks for your help

    • Andrei Girbea

      April 1, 2015 at 5:36 am

      Depends on what you mean by bright. This has a 300+ nits screen according to some reviews that use better tools to measure brightness than I can afford.

      Other modern laptops with bright screens are the Acer aspire s7-393 , dell xps 13 2015, macbook air 2015, samsung ativ Book plus 2015 and most other premium devices available these days

    quick question for you. I have not owned a laptop out side of work since my college one died in 2012. How would this laptop do with importing photos off a sd card? Maybe some quick touch ups and stuff like that but not heavy duty photo editing. On the fence between this and the xps13 just don’t want to spend the extra cash for a smaller sdd if the performance when it comes to moving photos around and small edits is not huge.

    Thanks for the help!

    • Andrei Girbea

      April 2, 2015 at 7:56 am

      Should be OK. You might notice some sluggishness when the files will be copied/imported, but otherwise it should handle this well enough. You’d better not use heavy image processing programs like Photoshop, and if you do want to use Photoshop, stick to an older version, like CS2 or something, and stay away from the more recent builds.

        October 1, 2015 at 7:21 am

        Dear Andrei,

        It’s October 1, 2015. In the $700 (plus or minus) dollar range which laptop would you recommend now? What’s the most bang for the buck? Also what’s does the -ASM1 mean on the Asus?

        Thanks for all your help.

      • Andrei Girbea

        October 1, 2015 at 11:17 am

        That a configuration series, their laptops are usually available in different configurations and each have a code like that one. Hard to say what’s the best laptop in that budget if you’re not telling me what you want from a laptop and what screen size you’re looking at.

    May 5, 2015 at 4:30 pm

    I have read the review – it is FANTASTIC! Thank you!!!! It looks as if this computer would work well for a student who uses it largely for Word, Excel, and Power Point.

    However, you briefly mention gaming but I am not sure to what games you are referring — would it work for Minecraft, Civilization 5 through Steam,, and SWTOR (online Star Wars game) — I don’t know how memory intensive those are and those are really the only four games that are played? This is much more in the price range that I want to spend — but if they wouldn’t work I guess I would look at the XPS13 – Thanks so much!!!

    • Andrei Girbea

      May 5, 2015 at 9:12 pm

      Minecraft yes, for sure. Civ 5, yes… as logn as you cram down some of the details. Not sure about the others, haven’t checked them out.

      Still, this is not something made for gaming. You buy it for the excellent price and the fanless platform, not the performance

      • DJ Caulkins

        May 6, 2015 at 2:52 pm

        Thank you so much! Then a could of final questions – do you think (I understand this is opinion)that it would be worth spending more money to get the XPS13FA? I do not want to buy a huge gaming laptop – I really want a small portable ultrabook because the vast majority will be word etc. However, for the occasional game – would there be drastically improved performance from the XPS13FA over the UX305 or without going to a dedicated graphics card will the performance on games be the same?

        I really appreciate your help!!! THANK YOU!!!

      • Andrei Girbea

        May 6, 2015 at 4:35 pm

        Yes, a Core powered device will be more powerful that a Core M machine in any situation. Unless you want to use the computer for basic activities (light browsing, email, office), the UX305 and other Core M devices will feel underpowered.

        Still, if possible, you could just give the UX305 a try and return it if it’s not what you want. An XPS 13 with i5 / 8 GB RAM / 256 GB SSD is nearly twice as expensive as the Zenbook and I can’t be the judge of whether it’s worth that much or not.

  10. James

    June 3, 2015 at 4:36 pm

    Please don’t buy this laptop!

    Got my first unit home, an discovered that the output to my AOC monitor for dual-screen use was very blurred/fuzzy. No tweaks to any settings anywhere made a difference, so I took it back, tested it in the shop – same problem on another monitor.

    Shop brought out a second unit, brand new, to test – same problem! Neither the shop nor ASUS could help. With my AOC monitor and my littles ASUS X205T I get a lovely crisp HDMI output. It seems there’s something wrong with the UX305 graphics module / HDMI driver. If you use a second display for anything then this laptop is not for you!

    • Andrei Girbea

      June 3, 2015 at 6:13 pm

      Hmmm, did you use the same microHDMI to HDMI connector in both cases? The hardware on this thing is pretty standard so I don’t see how there could by something wrong with it.

      • James

        June 3, 2015 at 6:18 pm

        Yes. Same cable, same monitor, tested twice with different monitors and still get the problem. Also tested my AOC monitor with the Zenbook and two different cables – same problem. In all cases no problem with my X205T

      • Andrei Girbea

        June 3, 2015 at 6:49 pm

        Weird. I’ve never tested that to be frank and never thought it could be a problem. Looks like others are experiencing problems with the HDMI port as well:

    Will there be a problem if softwares like Photoshop and SPSS are installed on this laptop? :) Thanks!

    June 27, 2015 at 7:17 am

    Hey! So umh I’m looking for an ultrabook, for college purposes and light gaming (Warcraft, dota, league of legends, etc). I’m expecting the system will be running with i3/i4/i5 4th/5th gen, with maximum weight of 1.5 kg. I have a very tight budget about $800-$1000. Any recommendation? And last but not least will the m5y71 able to beat the “I” processor in any sort of way?

    • Andrei Girbea

      June 29, 2015 at 11:03 am

      I would stay away from Core M if you want performance and especially gaming. The Core M 5y71 has one major strong point: it’s fanless. Performance wise, it’s worse than Broadwell i3 and it’s not very efficient either.

      You haven’t said anything about a screen size but if you want to play those games flawlessly, you’re going to need some sort of dedicated graphics. You could also go for something like the Intel COre i5-5200U processor, but it will struggle in certain scenarios unless you lower the resolution to 13 x 7.

    I am a grad student who uses a laptop mainly for browsing, microsoft office, MATLAB, virtualization software and presentations. I need a lightweight laptop to carry around easily and so, am considering the zenbook ux305, mainly because it is reasonably priced and lightweight. Do you think it is a decent choice or do I look for a laptop with a better processor ?


    • Andrei Girbea

      June 29, 2015 at 11:23 am

      No, look for something with at least a Core i5 processor and preferably 8 GB of RAM. the Core M platform is not meant for serious work.

  14. Gracie Zorua

    August 5, 2015 at 7:32 am

    There seems to be three versions/configurations of this ultrabook (as far as I’ve been able to tell) — the USM1, ASM1, and RBM1-GD. I know that the USM1 is the signature version/Microsoft version of the ASM1, but can anyone explain what the RBM1-GD is? Also if there is any difference between the UX305 and UX305FA.

    • Andrei Girbea

      August 12, 2015 at 12:58 pm

      The RBM1-GD is the golden version from what I can tell, while the other two are the Darker color.

      The UX305 is a series name, with models like the UX305FA (with Core M) or the UX305LA (with Broadwell U hardware).

    August 6, 2015 at 12:37 pm

    Any news on the 5Y71 in this machine?

    • Andrei Girbea

      August 12, 2015 at 1:11 pm

      There are models with the Core M 5y71 CPU shipping in the States (and perhaps other regions as well). For instance, the Core M 5y71, 8 GB RAM, 512 GB SSD model ships for $999 in the US. I haven’t reviewed one though.

    • Andrei Girbea

      August 13, 2015 at 9:05 pm

      There’s no way to upgrade the RAM on this computer.

    August 27, 2015 at 4:18 am

    I am a business student and im looking into the UX305. first, is there a technical difference between the USM1, ASM1, and RBM1? im not sure what they mean.
    Second, Would this laptop handle having 1-3 browser tabs open and a word or excel page open at the same time? i really only use the laptop for taking notes,browsing and netflix. not usually at the same time.

    • User

      August 27, 2015 at 11:48 am

      I always reconfirm the spec instead of following the SKU numbers. The SKU numbers are difficult to remember or keep track off.

      This notebook is quite a bit more powerful than is given credit. You can do all of what you have mentioned several times over and all at the same time and the laptop would still be able to handle it.

    Three questions:
    1): If I wanted to upgrade my 128 Gb to 256 Gb you mentioned that this can be done. I have found that San Disk do not retail their 256 Gb M.2 SSD (SD7SN3Q-256G-1002) and see that it is not available in the UK via normal sources. Can you advise a suitable OEM part that is compatible with the Sandisk M.2 80mm stick and where can I get it?
    2): Will the existing BIOS accept a 256 Gb SDD without upgrade ?
    3): When finally the battery fails can it be replaced or is this glued in place?
    I would appreciate some help without having to remove the back cover just yet.
    Kind regards.

    • Andrei Girbea

      September 4, 2015 at 2:43 pm

      1. Any M.2 SATA SSD shoudl work.
      2. I can’t tell for sure, but I don’t see why not
      3. TO be frank, I don’t remember exactly, but I think it’s screwed in place, not glued. So it should be replaceable, as long as you want a compatible one.

      • barrpeople

        September 4, 2015 at 5:44 pm

        Thank you Andrei for your quick response .. I just wanted confirmation, they were my thoughts too with the exception that I had no battery knowledge for the ASUS.
        Depending on price the additional 128 Gb might be a worthwhile upgrade.
        I liked your site and analysis of the Zen and I think it is a most worthwhile notebook especially for students and excellent size and weight for University lecture rooms.
        Not sure about this, but I think ASUS is phasing it out .. not that many about for sale at £650.
        Kind regards

        There’s an update in the works with Skylake Core M hardware, the Zenbook UX305CA. I think it should hit the stores in October/November.

  20. John S

    September 14, 2015 at 2:55 pm

    I have tested a few fanless designed and the one common flaw with smaller notebook designs with fanless is a case of heat buildup. Sometimes this buildup actually is enough for the CPU to begin to under clock itself to cool off. If your finding that streaming video is fine at first then becomes stuttering and freezes after a while. You may be experiencing this. I have a Stream 11 which I found out that the passive heat sink was not even contacting the CPU surface. The thermo tape did not even show a indication it was making contact. This also was proven as temp monitor showed rapid rise to 80C or higher and a clock reduction from 2.55Ghz burst to around 1.5Ghz or less. This is a pretty dramatic drop in performance. Given these are barely making the grade at max speed. A degrading effect of 1Ghz is a lot. This heat sink on the Asus looks better but still lacks anyway to move air over heat sink. Many small notebooks do not even have vents. I think this is rather bad design and its may be great to say its fanless. But if it affects performance its not so great.

    • Andrei Girbea

      September 15, 2015 at 7:05 am

      I agree and I wonder how that’s going to change with the Skylake COre M update and the 2nd generation of these fanless designs

    Hey hi Andrei,

    Just wanna ask if ASUS ZENBOOK UX305 with just Intel® Core™ M 5Y10C Processor, 4GB RAM and 128GB SSD be gud enough for storage of abt 10,000 pics? and would it be able to link up WIFI (5G – Fibre Broadband)?

    Let’s say.. If I were to use it to check out stock mkt’s price movements, will it lag?? and if I were to watch online movie for a few hrs, does it mean the laptop will be super overheat?

    As my bro’s ASUS S56C is unable to connect for 5G WIFI broadband services..


    • Andrei Girbea

      October 11, 2015 at 2:16 pm

      Not sure about the Wi-Fi compatibility, but should be able to handle all those other tasks fine

    hi Andrei
    thank you for your great review!
    I am starting my first year of collage in a week and looking for a computer for school – mainly words doc, youtube and browsing the internet. the Asus Zenbook UX305LA looks very good but it cost 749$, should I but it or pot the extra 50$ for the dell xps13 (non-tuch, 799$)?.

    also from the reviews it is hard for me to understand if I really need such a good(but expensive) computers – if I am not playing games or editing videos etc – maybe a cheaper one will be as good for me? – can you recommend one for me? my main points are – light, matte-screen and good battery life.
    thank you!

    • Andrei Girbea

      October 13, 2015 at 1:49 pm

      Are there similar specs on the UX305LA and the XPS 13? The Asus should be more affordable. Another option to consider is the Asus UX305FA, cheaper, but not as powerful as either of the other two.

  24. Simon

    October 14, 2015 at 7:03 pm

    Hey Andrei,

    I really appreciate your review, which is very helpfull. I wanted to buy a ux305la with an i7. However, I was concered with the HD 5500 Graphics because I also want to use it a little bit for gaming. So, by coincidence I looked up the ux303lb. It has a GeForce 940M, which from what I can say has more performance and in your review you also write that it is suited for gaming. Both ultrabooks got here in Germany the same price (even though the 303lb is older). Maybe you can give a recommendation? Thanks a lot my friend,

    • Andrei Girbea

      October 14, 2015 at 8:05 pm

      WEll, the UX303LB gets the dedicated graphics, more RAM (up to 12 GB) and a backlit keyboard, among others, but it is heavier and packs a smaller battery. If you plan to play some games, I’d choose it over the UX305LA. Just make sure you get the version with the 1920 x 1080 px screen, as the 3200 x 1800 px panel has known and severe color reproduction issues.

    Hey sorry for leaving a comment here. I didn’t know how to reach you for questions

    What do you think its better?

    Dell xps 13 9350 (i5/8/QHD sold by Microsoft) – 999
    Surface pro 4 (i5/4) -999

    please let me know. Thank you!

    This is going to be my secondary laptop (My main is macbook pro 15 retina)

    • Andrei Girbea

      October 30, 2015 at 12:50 pm

      That Surface is without a keyboard folio, right? So it’s not really a laptop. If you want to whole laptop experience, the XPS 13 is the better pick in this budget.

    I learnt that there is ASUS Ultrabook UX 305 FA with Intel core M SY 10 processor, 4GB RAM & 128 GB SSD. The main point here is that it has ‘touch screen’ and is available at Melbourne Austarlia.
    Is the touch screen available in this model?

    • Andrei Girbea

      November 23, 2015 at 2:46 pm

    Hi Andrei,

    I am from Asia and right now I have two available models which suits my budget. Could you help me to find out which one is best ? I have highlighted difference between the two models below.

    Intel Core M-5Y10(0.8 Ghz) ~ 2.0 Ghz 4M
    8GB DDr3 RAM (1600Mhz)

    ASUS UX305FA-FC031H
    Intel Core M-5Y71(1.2 Ghz) ~ 2.9 Ghz 4M
    4GB DDr3 RAM (MAX 10GB)

    I intend to use it for documentation, PDF reading, Music, light browsing and for watching offline videos/Movies.

      I may not even use it for much of multitasking. Waiting for your suggestion.

      Thanks in advance

      Hmmm, tough call. It would be great if you could fins the model with the Core M 5y71 processor and 8 GB of RAM.

      If you can’t, I for one would go for the later of the two, the one with the Core M 5y71 cpu if the price difference between the two models is small.

        Hi Andrei,

        The model with 8GB ram is available but it’ll surpass my budget.I may go for the second one as you had suggested. Just curious to know, does those variations in the first two models I had highlighted, really makes a difference for task I do?

      What’s wrong with the display resolution? Can you be more specific?

    I have had my Asus Zenbook UX305FA (with 8GB RAM and 128GB SSD) for almost three months and overall I am very happy with it but there are certain things that are not ideal. By the way, I find the above review very good and agree pretty much with everything that I had tried.

    First what I love about this machine:
    – It’s slick design and lightness make it ideal to slide into my backback and take it with me when before I would not consider bringing a laptop. On occasions I pulled the laptop out of my bag in a shop or a bank and quickly did what I had to do almost as if I was holding a tablet

    – The screen quality is fantastic and being non-reflective it works really well. The screen size at 13 inches is perfect for me.

    – I have a fast 100MB/s internet and I found performance more than sufficient for browsing and streaming. Occassionally, streaming does stop but not enough for me to get bothered and we also need to remember that it depends on the source of the stream

    – A major plus is the speed with which it powers up – we are talking literally 10 seconds and it’s up. That makes my life so much easier

    Issues that I found:
    – I have the 128GB version and 70GB was pretty much full very fast with system and a few apps and it was easy for me to add 30GB of some music and videos. Usable storage is only 110GB, so Im close to the limit much sooner than I would hope – Im considering an upgrade – either that or I need to carry external drive which I dont want to do

    – Despite advertised 10 hrs, I get typically 5 hours of usage that does include streaming. Running powercfg /batteryreport /output “C:\battery_report.html” shows about 5:40 hrs of expected usage. That is actually a bit of a problem. I was hoping for about 7 hrs given advertised 10 hrs. I will buy a power bank to support me when on my travels. The point is – I thought I didn’t have to do that. Incidently, I have seen many reviews of power banks for USB devices, but only sketchy ones of the power banks for laptops. (*)

    – I do not know if this is just my machine but running it on battery power for a day, usually means once/day or maybe once/two days, I the display goes dark and half a second later it returns with a message “Display driver stopped working but recovered” – First few times I ignored but it is a reasonably significant nuisance. Asus support asked me to send in the laptop but not having a laptop for several days is major inconvenience for me and interestingly I found other people in the internet suffering from the same issue (Asus claimed they do not know of this being a common problem). Of course, I tried updating all the drivers but still the problem re-occurs now and again.

    – the keyboard is not ideal but ok for me – it reminds of the new Macbook 12 inches which I really don’t like (very shallow – no spring in key presses). Asus keyboard only reminds of the Macbook 12″ version because it is deeper which makes all the difference

    – I have had issues with the Tuchpad – several times the cursor just stopped moving and I had to reinstall Touchpad drivers. Would have preferred not to do that

    – Also the Touchpad is more temperamental than one would hope and clicks are quite noisy – for me these are slight inconvenience

    – Another thing with the Touchpad is that using it for a bit even with fairly clean hands it looks a bit smudged – I don’t know what Apple cover their Touchpads with but I do not see that on their products. It is just a minor point, possibly a bit pedantic but still …

    – When the battery gets to 5% the machine powers off. It does not go to sleep, it powers off and it is impossible to get it back without charging. Not sure if the 5% is set somewhere but effectively it’s like haveing 95% battery.

    – Speakers are not great – OK, to listen to in a quiet place and good enough if you just want to listen to music yourself but you cannot expect too much in such a small space in such a slim design.

    It seems like I wrote a lot of negatives, but actually, overall I love this laptop because it is just so convenient, especially in comparison to the heavy machine I had before.

    Im definitely sticking with it and I cannot imagine upgrading in the future to anything other than a similar ultraslim laptop. Hopefully with these inconveniencies eliminated.

    Ok, so I wrote more than I intended to – sorry :-)

    Best regards

    (*) It’s a side issue but I would be interested in a review of at least the 4 power banks below (lightest, capacity 18000-30000mAh, all with 2 USB charging ports, plus two have LCD with remaining charge):
    1. RAVPower 23,000mAh Portable Charger Power Bank External Battery Pack
    2. ElectriQ Universal Laptop & USB Power Bank, 30,000mAh
    3. Poweradd Pilot Pro2 23000mAh Portable Power Bank
    4. AUKEY 18000mAh Multi-voltage

    In particular their own re-charging times are hard to find. Im looking pretty much for the lightest power banks capable of charing laptop with minimum 18,000mAh. Anything above 30,000mAh is problematic when taking on board airplanes.

      Hi Rob, thanks for the detailed feedback, this is going to help other readers for sure!

      I don’t have any experience with those power banks you mentioned. You should check out the reviews on and you can also ask your own questions there and owners might answer.

    The USB3 hub will default back to USB 2.0 if a device only capable of USB2 is plugged in so the comment above about only having USB3 ports is moot.

    I can't find the ux305 to buy anywhere in the UK. Do you know if there is much difference between the ux305, ux305ca, and ux305FA? Or what the current model is this series?
    Many thanks

    Hi Andrei,

    Thanks for this helpful review. I am looking for fanless laptops/ultrabooks with SSD storage and matte display. Can you please tell me of all such models you are aware of?

    Thanks a lot in advance!
