Asus Transformer Book Chi T100 review

The Transformer Book Chi T100 is a detachable - a 10 inch Windows slate with a keyboard dock

The Asus Transformer Books go a very long time again, to the beginnings of the 2-in-1s, as a number of the first Home windows detachables ever launched.

The Transformer Book Chi is the producer’s newest collection on the time of this publish, launched in 2015, and consists of three totally different units, the T90 with an eight.9 inch display, the T100 with a 10.1 inch display and the T300 with a 12.5 inch show, which we already reviewed a couple of weeks in the past.

This text is concerning the center choice, a detailed review of the Asus Transformer Book Chi T100. In only a few phrases, the Chi T100 is an entire redesign of the favored Transformer Book T100 collection, with a model new case, a better decision show with Lively Pen help and some different modifications right here or there, all constructed on prime of the identical hardware barebone used prior to now.

We’ll get to speak about all these within the subsequent rows, so stick to me if you wish to know whether or not the Chi T100 is value your hard-earned buck or not.

Design, exterior and first look

There’s no argue this factor is stunningly lovely, with its Darkish Blue metallic case and shinny beveled edges, which can scratch and dent simply although. The truth is, you possibly can see some marks on this check unit already, even if it’s just a few weeks previous, so deal with it properly.

The Transformer Book Chi T100 is a detachable - a 10 inch Windows slate with a keyboard dock

The Transformer Book Chi T100 is a removable – a 10 inch Home windows slate with a keyboard dock

The Chi T100 can also be compact and extremely moveable, because the slate alone measures simply zero.Three of an inch in its thickest level (that’s near a daily journal) and weighs 1.25 kilos, whereas the slate and the dock mixed tip the size at round 2.four lbs, numbers different detachables in its class can’t match.

I’m assured Asus might have made this even lighter in the event that they went with a plastic case, however they opted for the premium metallic construct as an alternative, and that wasn’t a nasty name in any respect. At 1.25 lbs the Transformer Book isn’t a match for different fashionable 10-inchish slates just like the iPad Air or the Samsung Galaxy Tab S, however continues to be mild sufficient to be maintain comfortably for an extended time, with out inflicting fatigue.

The very slim form-factor does imply you’ll need to stay with miniaturized ports: two microUSBs on the slate (one microUSB 2.zero on the decrease left, additionally used for charging, and one other microUSB Three.zero on the proper), microHDMI and a microSD card-reader, however that’s a sacrifice I’m prepared to make. However, the T100 doesn’t get the microUSB to USB adapter (OTH cable) within the pack, in contrast to the bigger T300, which suggests you’ll have to purchase it your self.

Dock, keyboard and trackpad

A dock is included within the pack alongside the pill, to which it latches magnetically. The hinge is extra compact than on the earlier Transformer Books, however nonetheless strongly constructed. Sadly although you possibly can solely lean it again to about 120 levels, which suggests you’ll wrestle to observe the display heads-on in lots of conditions. Asus went with this strategy as a result of the system is prime heavy (the precise slate in heavier then the dock) and a bigger angle would have induced the ensemble to fall on its again, like on the Acer Aspire Change 10 E examined a couple of days in the past. Nonetheless, I’d quite have that occur than stay with this limiting hinge.

The 2 halves usually are not bodily related although, like with the older Transformer Books, as a result of the dock is merely a help for a Bluetooth Keyboard and Trackpad, with a small battery inside used to energy them. It doesn’t home any storage, and the prevailing microUSB slot is just used to cost it up. Trigger sure, you’ll need to cost it independently. Asus went for this strategy on their whole Chi line and I’m undoubtedly not a fan.

The pill expenses by way of microUSB as properly and you should use the included charger to fill-up the dock, or you need to use a microUSB to microUSB cable to attach the dock to the slate and cost it this manner (the cable shouldn’t be included although, once more, in contrast to with the T300 Chi). Fortunately the keyboard gained’t run out of juice simply, so I’d reckon you’ll solely should cost it as soon as every week or so, and Asus does embrace an App that allows you to know when it’s getting brief on juice. Plus, because the battery contained in the dock isn’t very massive, it costs up shortly.

OK, so we now have a Bluetooth Keyboard and Trackpad right here, however are they any good?

Properly, not likely. The keyboard on the Chi T100 is extra cramped than on the older 10 inch Transformer Books, primarily as a result of the complete system is extra compact now. That results in brief rectangular keys with little area in between. They do really feel good to the touch, with a barely rubbery costing on prime, and behave fairly properly, as they’re agency and journey a good quantity into the body, however are so small that you simply’ll wrestle to hit the proper one, particularly in case you have bigger arms, which enormously hinders the typing velocity and general typing expertise.

The trackpad sitting under the keyboard isn’t excellent both. It’s small, however does really feel good and clean firstly. Nevertheless, after utilizing it for the final week I can conclude that it’s typically imprecise, does miss faucets once in a while (particularly mild ones, which suggests you’ll should faucet more durable to make them register) and provides poor palm-rejection (and your arms will finish on prime of it very often, given the gadget’s small measurement). On prime of those, because it’s an Asus TouchPad, you’ll be able to’t tweak it in any means from the settings, different from disabling and enabling some gestures.


On paper the display Asus placed on the Chi T100 is spectacular: an 1920 x 1200 px IPS panel with a digitizer and help for lively pens.

The facet ratio makes it higher than most different 10 inch Home windows slates for portrait use, which I for one favor when searching, studying or spending time on Twitter and Fb.

In follow, you’ll love the decision, the brightness, the viewing angles and the distinction. However for those who require correct shade copy, you’ll should look elsewhere, trigger the panel is tousled on this specific space and a calibration run might solely repair little or no, at the least on my check mannequin, which is a final-production unit similar to those yow will discover in shops. Take a look at the numbers under:

  • Panel HardwareID: AUOptronics AU017D8;
  • Protection: 76% sRGB, 56% NTSC, 59% AdobeRGB;
  • measured gamma: 1.Three;
  • max brightness in the midst of the display: 370 cd/m2 on energy;
  • distinction at max brightness: 660:1;
  • white level: 6600 Okay;
  • black on max brightness: zero.56 cd/m2;
  • common DeltaE: 9.52 uncalibrated, 6.56 calibrated .

I haven’t been capable of check the digitizer/Pen help although, as a Pen is just not included within the pack and I don’t have any Lively styluses round. That’s a pity because it is likely one of the Chi’s foremost promoting factors, so if any of you possibly can share one thing on this matter, be happy to do it within the feedback part and I’ll replace this part.

Hardware and day by day use expertise

The Transformer Book Chi T300 that is powered by Intel Atom BayTrail T hardware, with an Atom Z3775 CPU, solely 2 GB of RAM and 32 or 64 GB of eMMC storage, and that may in all probability disappoint a few of you. The CPU is decently quick for what it’s, nevertheless it does help four GB of RAM and it’s unlucky Asus don’t supply such a configuration. It will have in all probability been costly, as a result of it will have needed to be paired with a 64-bit model of Home windows eight.1, and never the 32-bit model out there now on these fashions. However the choices would have been certainly appreciated by some potential consumers.

The hardware just isn’t upgradeable in any method and the included eMMC proved to be surprisingly sluggish on my unit. My mannequin got here with the 64 GB eMMC, however I’ve seen reviews of the 32 GB mannequin being sluggish as nicely. Nonetheless, there’s a discrepancy between the outcomes I acquired on CristalDiskMark (93 MB/s learn , 38 MB/s write) and Atto Disk Benchmark (175 MB/s learn, 50 MB/s write) that I can’t clarify. In on a regular basis use the storage feels a bit sluggish, however as soon as you put in all of the packages you want, that shouldn’t actually be an issue.

The BayTrail T platform is environment friendly and able to coping with the day by day routine, from shopping to watching all types of multimedia content material and modifying Workplace paperwork. Efficiency is boosted by the clear Home windows set up, with just a few preinstalled packages included. The sharp and shiny display does assist with the multimedia expertise, however the two audio system positioned on the sides sound quite tiny and quiet, thus won’t fulfill the audiophiles amongst you.

BTW, a 1 yr Workplace 365 Private subscription is included with this gadget, which additionally consists of 1 TB of OneDrive storage for one yr. That’s not one thing particular although, as most 10-inch Home windows slates bundle an identical package deal and also you’ll need to pay $69.99 per yr to resume the subscription after the primary yr.

Nevertheless, with Intel’s newer Cherry Path platform coming out right here and there, a few of you may contemplate the hardware on this gadget dated. And that’s going to be an issue for Asus down the road, when this system should face extra reasonably priced CherryTrail slates, and never simply the Microsoft Floor Three out there at this time.

Anyway, listed here are some benchmarks outcomes and under you’ll discover some particulars on efficiency and internal temperatures whereas going via a number of totally different informal duties (shopping, watching 1080p Youtube clips, typing, looping a 1080p .mkv file, and so forth).

  • 3DMark 13:  Ice Storm – 17684, Cloud Gate – 1406, Sky Diver – 524, Hearth Strike – NA;
  • CineBench 11.5 32bit: OpenGL 6.82 fps, CPU 1.49 pts, CPU Single Core zero.36 pts;
  • x264 Benchmark four.zero: Cross 1 – 47.15 fps, Move 2 – 9.49 fps;
  • Octane 2.zero on Chrome: 7908 factors.

You’ll discover the hardware retains withing common temperatures even when coping with extra demanding chores and that’s seen on the surface as properly, the place the case merely will get heat, regardless of being totally manufactured from aluminum, which tends to drive warmth simply.


*Day by day Use – 1080p Youtube clip in IE for 30 minutes

When you’ll run demanding software program or 3D video games the metallic shell will attain temperatures between 35-40 levels Celsius, which might make it a uncomfortable to carry and will trigger sweaty arms.

I also needs to point out that the Broadcom Wi-Fi module Asus placed on this system isn’t very quick and will solely present somewhat sluggish obtain speeds of as much as 50 Mbps even when subsequent to the router. That’s going to be sufficient for searching, streaming content material, occasional downloads or different every day actions that might contain an Web connection, however different 10 inch Home windows slates do supply quicker wi-fi. However, the speeds and sign remained constant when getting additional away from the router with partitions in between, which was a bit shocking, given the Chi’s metallic casing.

Final however not least, Asus put two cameras on this system, a 2 MPx front-shooter and a 5 MPx essential digital camera on the again. The latter does take respectable footage in good mild, whereas the webcam is grainy and really darkish, however must be sufficient for some occasional Skype calls.

Battery Life

Asus managed to squeeze a 30 Wh battery on this skinny pill they usually corroborated it with a really environment friendly hardware implementation, which suggests the Chi T100 gained’t disappoint with regards to battery life. I’ve set the display to 30% brightness, which is about 120 nits, and right here’s what I obtained:

  • 2 Wh (~15 h of use) – idle, display at zero%, Wi-Fi OFF;
  • Three.1 Wh (~9 h 30 min of use) – very mild searching and textual content modifying in Google Drive, display at 30%, Wi-Fi ON;
  • Three.2 Wh (~9 h 30 min of use) – 1080p fullscreen video on Youtube in Web Explorer, display at 30%, Wi-Fi ON;
  • four Wh (~7 h 30 min of use) – 1080p fullscreen .mkv video in VLC Participant, display at 30%, Wi-Fi ON;
  • four.5 Wh (~6 h 40 min of use) – heavy shopping in Web Explorer, display at 30%, Wi-Fi ON;
  • four Wh (~7 h 30 min of use) – 1080p fullscreen video on Youtube in Chrome, display at 30%, Wi-Fi ON.
Expect between 6 to 10 hours of daily use from the Chi T100

Anticipate between 6 to 10 hours of day by day use from the Chi T100

The slate fees by way of microUSB and that takes some time (round Three hours), plus Asus solely features a brief Three-feet cable with the power-adapter, which might make the method of utilizing the gadget whereas charging it relatively annoying.

Consumers complained about this on the older 10-inch Transformer Books, however Asus selected to do nothing about it. Shopping for an extended USB to microUSB cable might be an answer, however not-using an unique Asus USB cable result in for much longer charging occasions up to now, which might be going to be the case right here as nicely.

Pricing and competitors

You will get the Transformer Book Chi T100 for both $399 or $449, however will certainly get cheaper down the road. Comply with this hyperlink for up-to-date costs and configurations on the time you’re studying this submit.

Each fashions embrace the slate and the dock, the Atom processor and a couple of GB of RAM, however the cheaper model comes with 32 GB of space for storing, whereas the $449 mannequin will get a 64 GB eMMC. I’d avoid the 32 GB mannequin as a result of it solely leaves about 20 GB of area with a recent Home windows set up and also you’ll in a short time run out of area simply by performing some updates and putting in primary packages (antivirus, workplace, and so forth).

Microsoft Retailer additionally sells a Signature Version mannequin for $549, which given how there’s little bloatware on the usual Asus model anyway, is certainly not value $100 additional.

So the one viable choice stays the $449 one. If you would like a modern and delightful Home windows-running 10 inch slate with a digitizer and pen help that you simply’re solely going to make use of for mild day by day actions, you’re hardly discover something higher for a similar sum of money or much less.

Final yr’s Asus Transformer Book T100TAM (my detailed review is out there right here) nevertheless may be purchased for underneath $250 proper now (comply with this hyperlink for up-to-date costs) and provides the very same hardware specs, however solely a 1366 x 768 px show with out digitizer. It’s marginally bigger and heavier, however does embrace an USB Three.zero slot on the dock and area for a 2.5-inch SSD/HDD inside. So it’s a extra sensible and less expensive choice, until you actually need the digitizer and high-res show.

The Transformer Book T100TAM is a simpler and much cheaper alternative

The Transformer Book T100TAM is an easier and less expensive various

There are a couple of different choices that embrace quicker hardware and particularly extra RAM, however they are typically costlier. Nonetheless, take a look at the Lenovo ThinkPad Pill 10, the Microsoft Floor Three or the Dell Venue Professional 11, amongst others, in addition to my detailed submit on the most effective 10 inch Home windows pill and mini laptops out there proper now.


On the finish of the day, I really feel that Asus determined to create a 10 inch Home windows 2-in-1 that appears and feels higher than anything in its worth vary they usually truly succeeded with the Chi T100. Sadly that meant a few of the sensible features needed to be sacrificed, and that features the keyboard, the IO and even the hardware, to some extent.

Which brings us to the necessary query right here: is the Transformer Book Chi T100 value your hard-earned buck? Nicely, if the dimensions, aesthetics and pen-support are excessive in your priorities listing, this gadget might be what you want. However in the event you’d relatively get a extra succesful 2-in-1 with ports, extra space for storing and a nicer keyboard, there are higher choices for you on the market. Or far cheaper ones. Once more, my listing of one of the best 10 inch Home windows pill and mini laptops is the right place to start out your search.

With the Chi T100 Asus sacrificed practicality for aesthetics. Is that a trade you're willing to make?

Anyway, that wraps it up for now. Let me know what you consider the Transformer Book Chi T100 within the feedback part under and be happy to get in contact in case you have any questions or something so as to add to this review.
