Teclast T70 tablet review

Bigger than an iPad Pro, cheaper than most – Teclast T70 tablet review

Huge display, small price.

For less than $400, you can get the Teclast T70, a tablet featuring a massive 14-inch screen, cellular connectivity, GPS location services and enough power for everyday use. Thanks to its large size, it's the perfect device for movie fans and readers of digital newspapers. But you surely have to make some compromises for the price, don't you?

Verdict on the Teclast T70

Only few tablets come with screens bigger than 14 inches in size and for a price of below $400, the Teclast T70 barely faces any competition. Naturally, you'll have to make do with average performance and the occasional system stutter as a result of its low price.

Nevertheless, you shouldn't ignore the fact that the Teclast T70 suffers from some problems: Its touchscreen sometimes only responds after multiple taps and trying to stream at over 1,080p leads to a stuttery mess.

You also shouldn't get your hopes up with regards to software updates, and the tablet's WLAN internet connection isn't the fastest.

Its runtimes are fit for everyday use and its location services are precise enough, so you can use the tablet as a navigation device.

You should take some time to think about whether the Teclast T70's cheap price is worth all these limitations, or whether you should instead go for an older model from a different manufacturer for a few dollars more.

That being said, if you are desperately looking for one of the cheapest tablets to have a huge display, then you'll get a solid device nonetheless.

Pros

+ stable metal case
+ huge display
+ LTE and GPS
+ no PWM flickering
+ good runtimes
+ barely heats up
+ affordable

Cons

- barely any updates expected
- slow WLAN
- limited Bluetooth audio codecs
- heavy
- 4K streaming mostly not supported

Price and availability

You can order the Teclast T70 from online retailers such as AliExpress, where it currently costs $318.82.

Case – Metal with imprinted antennas

Teclast has gone for a metal case that doesn't feature any unsightly plastic strips to ensure better reception—instead, these are imprinted into the tablet's sides. The only available colorway is blue. Its camera module is set off by glass, which concentrically refracts light rays.

The tablet's case is well made: Material transitions and gaps are hardly noticeable.

Despite its size, the device is stable and only occasionally emits quiet creaking noises when twisted. However, weighing in at 960 grams, it is relatively heavy. It features no designated water or dust protection.

Connectivity – With a 3.5 mm audio jack

Even if the Teclast tablet is advertised as having 20 GB RAM: Only 8 GB are physically installed, the rest is supposed to be solved via a swap file, but we don't find this to be a sensible solution due to the much slower data storage. 256 GB of mass storage is at class level, other storage variants are not offered.

The Teclast T70 is equipped with Bluetooth 5.2 and also features a 3.5 mm audio jack. The tablet doesn't have an NFC chip.

microSD card reader

The device's storage can be expanded via a microSD card and the reader proved to be quite fast during our test alongside our Angelbird V60 reference card: it could even keep up with card readers in significantly more expensive tablets.

Software – Little update hope

The manufacturer has equipped its tablet with Android 14 from 2023. You shouldn't expect many updates: At the time of testing, the latest security patches were from August 2024, so hopelessly outdated.

It is nice that Teclast hasn't installed any third-party software ex works.

Sustainability

Unfortunately, we have hardly anything positive to report in terms of the tablet's sustainability: Plastic film is still used in its packaging and there is just as little information on its CO2 footprint as there is on the materials the manufacturer has used.

Communication and GNSS – Even with LTE and GPS

The Teclast T70's communication features, which include Wi-Fi 5, LTE and satellite location services, are quite comprehensive for such an inexpensive tablet. However, the first cracks in the picture appeared in the Wi-Fi data rates we measured using our reference router, the Asus ROG Rapture AXE11000: Here, the Teclast tablet only managed just over 100 MBit/s in some cases. This is enough for surfing the web, but since there were occasional drops to just over 50 MBit/s, this will become noticeable during everyday use.

You can use the cellular network to access the internet, and there are even two SIM slots available to do so. However, its frequency support is limited, so accessing the LTE network may be restricted when traveling abroad.

On the other hand, the accuracy of its GPS positioning was quite good in our practical test: On our cycling trip, the Teclast T70 deviated only slightly from our actual route and once apparently showed us as driving through a house. That being said, if you don't require absolute accuracy, then the tablet can be used for navigation purposes.

Telephone functions and call quality – Clearly audible

You can use the Teclast T70 for telephone calls.

This can be done via the two microphones and the speakers, or via a headset. Its call quality using the internal sound system is good and we clearly understood the other party during our test. When we spoke, we had to make sure not to be too quiet, otherwise we couldn't be heard on the other end of the line.

Cameras – A blurry affair

Photo taken using front-facing camera
Photo taken using front-facing camera

Especially when it comes to such a large tablet, cameras aren't necessarily intended for taking photos, but rather for scanning QR codes or reading documents.

The photo quality of its 13-megapixel main camera is at best only adequate for snapshots: It quickly gets into trouble with high brightness differences and on the photo of our surroundings, you can see the weaknesses in its image sharpness even without zooming in. In lower levels of light, colors are distorted, a strong graininess can be seen, and there are issues with sharpness and dynamics.

You can at least record videos in 2K and at 30 fps, but the autofocus is quite slow.

The front-facing camera has a resolution of 8 megapixels and will hardly satisfy selfie fans. Even so, it's sufficient for video conferences that don't have high-quality requirements.

Accessories and warranty – Power supply included

The packaging contains a charger and a USB cable, as well as a SIM pin.

The Teclast tablet is covered by a standard 12-month warranty.

Input devices and operation – No fingerprint sensor

The Teclast T70's screen operates at a maximum of 60 Hz, so it isn't quite as responsive as others. Nevertheless, it's usually fine to operate. But if a lot of power is demanded of the tablet, inputs are sometimes no longer implemented, for example, the brightness control for the screen no longer works correctly.

There is no fingerprint sensor, but the tablet can be unlocked via facial recognition. However, as this is only done via the front-facing camera without a supporting sensor, it isn't quite as secure and isn't permitted by Android for some applications, such as unlocking online banking apps.

Display – The competition is brighter

Sub-pixel array
Sub-pixel array

The Teclast T70's IPS screen has a slightly lower resolution than that of more expensive rivals and isn't as bright, managing a maximum of 402 cd/m² during our test. Its brightness is sufficient for working or watching movies indoors, but it's better to seek out some shade outdoors.

We didn't note any PWM flickering during our test.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8377 (minimum: 5 - maximum: 343500) Hz was measured.

Its display of colors and grayscales is only moderately accurate—a slight color cast is visible to the naked eye. Blue tones in particular are clearly distorted.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
23.6 ms ... rise ↗ and fall ↘ combined↗ 11.3 ms rise
↘ 12.3 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 51 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (20.6 ms).
       Response Time 50% Grey to 80% Grey
38.8 ms ... rise ↗ and fall ↘ combined↗ 20.7 ms rise
↘ 18.1 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 56 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (32.2 ms).

Performance – Usually good enough for everyday use

Teclast has installed the MediaTek Helio G99, a popular mid-range SoC, into its tablet. Unfortunately, it's already three years old and barely stands a chance compared to the performance of more expensive tablets. During everyday use, you'll have to make do with some occasional stutters, especially during more intensive tasks.

Video qualities above 1080p lead to heavy stuttering when streaming on YouTube. This is a shame, as it means you can hardly use the tablet's large screen for particularly sharp video material.

You can only expect 60 Hz gaming for graphically very simple games, as its GPU power is usually only sufficient for a maximum of 40fps.

When surfing the web, you'll often have to live with slow page loading on larger websites, even if your internet connection is good.

The device is equipped with UFS 2.1 flash storage. This is significantly slower than higher-priced large tablets, but still fast enough for reasonably quick data transfers during everyday use.

Speakers

The Teclast tablet comes with four speakers that produce a decent sound. They can get quite loud and even reproduce some bass frequencies. Nevertheless, music sounds somewhat distant and not as full as on higher-quality sound systems.

It's a shame that only the most basic codecs are available for audio output via Bluetooth.

Runtimes

Although the tablet's 10,000 mAh battery isn't that powerful compared to similar tablets, it still ensures good runtimes: we measured 15:43 hours in the WLAN test, so you can easily surf the web for a whole day without having to plug it back in. You can even watch movies from its internal storage for over 17 hours, which is enough to watch almost 3 seasons of Breaking Bad, for example.
