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. 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!

  2. 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.

  3. 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.

  4. 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:

  5. Why cant I comment?

  6. news about the x6 ?

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

  7. 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.
