Teclast X4 Hands-On Review

Teclast X4 Hands-On Review

Hands-on with the new Teclast X4 an 8GB RAM + Celeron N4100 Windows 10 tablet with a decent type-cover style keyboard and fully laminated keyboard. This new 11.6″ tablet from Teclast is decent and a very good Surface Go alternative with an easy access hatch under the kickstand to upgrade the SSD. A great move I want to see even premium tablets with this, the slot itself surprises with all 2242, 2260 and 2280 sizes possible. Just make sure it’s an M.2 SATA3 spec drive and not NVMe and you’ll be fine.

So even though this was just my unboxing and first look it’s pretty much a full review of it as I’ve discovered all the ins and outs to it. Only a few things are missing, battery life exact figure and thermals. Thermals I can report are fine, it’s clearly using copper in there to cool the N4100 Gemini Lake SoC and possible thermal pads. Teclast has gone with the default 6W TDP probably for the best battery life Vs performance compromise. And it runs smooth and as expected for a Celeron N4100 with 8GB of RAM in dual channel.

Battery Life

As for battery life, about 5-6 hours as stated in my video above is a fair good estimate. Depending on screen brightness and use. The 26.6Wh battery falls well short of the 37Wh battery we typically see in the Gemini Lake laptops. With only an 11.6″ screen and the SSD slot, they didn’t have a lot of space to work with.

The Teclast X4 does support Type-C PD charging tested and working as well as my external PD battery pack. The overall build of the tablet is great very good and the type-cover the keycaps have a nice rubberised matte finish with good key feedback. No missing keystrokes or issues.

Pros & Cons?

The only cons are the touchpad is small (As expected), the battery life isn’t amazing (as expected) the right USB 3.0 port doesn’t seem to like large external spindle hard drivers. It will either not work or cut out and then work at USB 2.0 speeds. Flash drives work at USB 3.0 speeds so it’s having some power issues on the battery. The left port works fine on my unit.

And yes, super weak speakers. Front facing is good to see but they sound so flat and lack volume. Using software to boost their loudness helps but won’t fix their bass output which is zero almost. Oh and the stylus, not a pressure sensitive one. I will not be getting it.

Otherwise, the performance is as expected, completely unlocked bios and it has top build, very solid well put together and the type-cover I really nice it. This is one of the better Windows 10 tablets to come out of China.

  1. @Tobi Thank you for the Driver goodixtouchdriver.inf_amd64
    i have istalled it on my x4 but i have the issue that if i touch top the touch replay is at bottom. so top an bottom is invertet,
    how can i fix this Problem?

  2. Hi Toby or anyone can help me?
    “warning about teclats x4!!! IF YOU LOST OR UPDATE OR REINSTALL os WINDOWS 10”
    Hello! I have the same problem I downloaded the drives but I was only able to install goodix, the kionix I can not know which device that controls. now the touch works but even after calibate when I touch it looks like the screen is inverted, I touch the bottom of the screen and the touch appears at the top. can you can help. do i need to install…

  3. any amazon link for a type-c charger? not power bank, classic d/c charger

  4. Does it support Hungarian language (magyar)?

  5. Bought the 256GB version on Taobao, could not get it to speak English, so did a quick Windows 10 clean install using the drivers from here.
    Everything is working great, can even charge using my phones 25W PD charger.
    Happy camper here….

  6. Hi Toby, I have identified the culprit. Apparently its the USB C port. Whenever I try to connect my USB C hub to it, the whole unit will be a super battery drainer. However, when I left it alone (ie, just use the 2 USB 3.0 type A ports), the battery didn’t drain at all.

  7. On a side note, I am experiencing severe battery drain when using a USB C dongle with the x4. Anyone experiencing the same? Any workaround?

  8. anyone experiencing the battery in discharging state despite that the unit is plugged in? As I am planning to use the x4 for some tethering photography, I noticed that the battery is discharging despite that it is plugged in.

  9. Thanks Toby. I managed to get the touch screen working again after installing the drivers. I didn’t follow the youtube link you gave but apparently was able to install the driver directly by right clicking the file with the ‘gear’ icon. How did you copy the drivers from the x4? I tried cloning from another x4 (another set of mine with a broken screen) but to no avail.

    • Copies of the systems drivers can be found in the folder… C:\Windows\System32\DriverStore\FileRepository

      If you have access to a running machine like I do, it’s really easy to go into device manager and find the name of a file used by the driver, then search for it in the above folder. Then all I do is zip up the folder which contained that file and bam, you have the drivers ready to install. Unfortunately this won’t work for all driver packages, but it’s fine for the ones listed.

      I’d also recommend downloading and running Intel’s driver detection app, as that should hopefully install the chipset drivers that may also be missing… https://www.intel.com/content/www/us/en/support/detect.html

  10. Sorry noon here. How do i installs the drivers ? Also, the HID – compliant touch screen is missing from the Device Manager.

  11. Does anyone know what stylus works with this tablet?

    • I sent a message to Teclast and they let me know that the TL-T6 will work on the X4. But I haven’t tested this yet. Will let you guys know if I get one and it works.

  12. warning about teclats x4!!! IF YOU LOST OR UPDATE OR REINSTALL os WINDOWS 10 you will lose touch screen features and there is no place to get or drivers or solution or windows original images. i think is a good product with 0 support actually im writing that comment using it but without any hope to get my touch feature come back to my tablet anymore.if somebody know or have some drivers or windows images to restore my drives i really appreciate your help!

  13. hello, how are you charging with usb-c, is that I’m trying with 2.1A and QC3 chargers and nothing, and 2 powerbanks and neither

    • I had to use a UCB-C to USB-C cable with my PD/QC supported power bank (which has 2 x USB-A ports and 1 x USB-C). For some reason if I just plugged a general USB-A to USB-C cable into the Teclast X4 USB-C port, it wouldn’t charge.

    • The 2 devices that I’ve tested and have confirmed working are my Motorola G7 Plus 27 watt wall charger and my Kogan Power Bank (https://www.kogan.com/au/buy/kogan-26800-mah-power-bank-75w-pd-and-qc-30/), both using a USB-C to USB-C cable.

  14. Hi guys,
    I was baking the Chuwi Ubook but this seems to be plagued with problems… I am in the market for a cheap/reliable tablet which will not leave me in the lurch when I upgrade windows 10 (looks like some tablets am have recurring driver issues). Preferably with stylus support.

    I was wondering if Teclast x4 or alldocube knote 5 would fit the bill.

    What do you guys think?
    Any other options?

    Thank you!

  15. Thanks Chris for the review! It is a very nice tablet. I intend to buy it. But I would like to know if it has a built-in Lan card. Indeed, I would like to know if it is possible to connect ethernet/usb adapter, so that I can use my Enigma2 satellite receiver (Zgemma H5).
    Best regards!

    • HI, yes it has a built in Wifi AC 2.4Ghz/5Ghz and you can use a USB to ethernet adaptor just fine.

  16. Hi Chris, thanks for the review. I own a Knote 5 and I was thinking about replacing it for this one because I don’t like the bulky folio type cover. I actually don’t mind the 4 gb for the kind of uses I give to this 2 in 1, and I like that the tablet itself it’s quite portable if you leave the folio at home. So, I don’t know if changing it for this one it’s actually a good idea just to get the kickstand. What’s your opinion when comparing these two devices?

    • KNote 5 and this are similar, but a slightly better build here and fully laminated screen. Performance is the same unless you need that 8GB of RAM and kickstand I wouldn’t change it for this.

      • Thank you for your opinion Chris. I’m really OK with the 4 GB of ram as I’m not doing any processor intensive job with the Knote 5. Taking into account that I paid 264 USD for it with the folio type cover, I really cannot complain too much about it. I will keep it until a a radically better low cost 11 inch windows tablet appears in the market.

  17. You need to do that full review Chris!

    Mine gets 98-105 degrees celsius just using the tablet normally in Windows (really scared what will happend when I try to play some games).
    In geekbench the CPU goes up to 100 celsius, even though I get a higher score in geekbench than you.

    Would be nice to know if you get any heat issues, as mine gets really hot to touch..
    I probably have to open up the tablet and do that Cube i9 mod, but I am afraid to open it up, before someone else have tried it!
    Will you do a thermal mod for this tablet? I am not sure if its easy to open this tablet up, waiting for someone to find out!

    This are the BIOS settings it shipped with:

  18. Why cant I comment?

  19. news about the x6 ?

    • I’ll have it soon finally shipped out, only like 5 months late!!!! Teclast have huge 7Y30 stock issues apparently.

  20. Thanks for the review Chris, looks like a proper 2-in-1, finally. Too bad it isn’t 3:2, that would have been perfect. Still, might just scoop it up if the price drops to that $329 again.
