Teclast 有很多型号的平板电脑在销售，尤其是在亚马逊等网上商店。这家中国制造商的产品已经引起了相当大的兴趣，因为它们大多价格相对低廉，而且还能提供足够的电量供日常使用。此外，这些产品通常至少具有一项与众不同的功能，如支持移动数据、大容量存储空间或超强电池。

Teclast T40 Air 是一款中端平板电脑，目前的售价远低于 200 美元。它采用 10.36 英寸显示屏，便于携带，外壳相对纤薄，甚至可以使用 4G 网络。让我们来看看 T40 Air 在测试和日常使用中的表现。

外壳 - 现代金属

制造商选用了金属外壳，在顶部边缘有一个小塑料插件，以确保更好的移动网络接收。深灰色的外壳质感很好，稳定性也不错--不过，当我们在打开屏幕的情况下扭动平板电脑时，我们注意到了一些图像错误。此外，扭动时还会发出一些细微的吱吱声。

边框相对较薄，但仍能让你舒适地握住平板电脑，而不会意外启动触摸屏。设备重量为 464 克，不算太重，可以长时间握持而不会让手臂过于劳累。

该平板电脑没有任何防尘保护措施，这意味着您最好不要让平板电脑沾染太多水和灰尘。

连接性 - Teclast 平板电脑拥有大量存储空间

这款平板电脑拥有 256 GB 的存储空间，在这个价位的平板电脑中非常抢眼，为你提供了足够的空间来存储图片、视频和其他许多东西。8 GB 内存对于这个价位的产品来说也是非常宽裕的。

该设备的 USB-C 端口内部只能以 USB-2.0 的速度连接，导致数据传输速度偏慢，同时无法通过线缆将屏幕内容传输到外部显示器。

它有一个 3.5 毫米音频接口，这意味着你也可以顺利使用模拟耳机。不过，它不支持 NFC，因此无法使用非接触式支付服务等。

如果水平放置平板电脑，SIM 卡和 microSD 卡插槽位于机身右侧。在这里，您可以安装一张 nano SIM 卡，以便使用移动数据或拨打电话。对于后者，如果您不想让路人听到您的谈话，我们建议您使用耳机。

microSD 读卡器

在我们的测试中，Teclast T40 Air 的 microSD 读卡器在使用 Angelbird V60 作为参考卡时速度相当快。这样就可以轻松扩展平板电脑本已很大的存储空间。

软件 - 不安全更新

制造商安装的操作系统非常接近Android 13。它没有安装任何膨胀软件（第三方赞助的应用程序）。在测试时，最新的安全补丁是 2023 年 6 月的，并不是很新。

在询问制造商后，它告诉我们可以更新到新的Android 版本。目前，该公司正在对其所有产品的更新供应情况进行汇总，应该仍会在 2023 年发布。过去，Teclast 平板电脑的新软件版本相当零散，不过，它们似乎总能解决用户报告的任何问题。

它通过了 Widevine 认证，这意味着您还可以观看高清流媒体内容。

通信和全球导航卫星系统 - 包括移动数据

WiFi 5 是 Teclast T40 Air 所掌握的最快无线局域网标准，传输速率相当稳定（高于同价位卡匣的平均水平）。在靠近路由器的地方，网页加载速度相对较快，而且可以接收到全部信号。在距离路由器 10 米远的地方，中间隔着三堵墙，我们只能接收到 3/4 的信号，有时网页加载需要花费一些时间。

在这个价位的产品中，有一样东西并不总是标准配置（尽管它也不是全新的）：Teclast T40 Air 支持 LTE。它可以使用多种频率，这意味着在仅限于本国大陆的旅行中，至少不会有任何网络连接问题。在我们的测试中，信号质量尚可，但比高端手机稍差。

在我们的测试中，定位模块在使用应用程序时工作得并不好--它确实能找到不少卫星，而且几乎能与所有较大的网络一起工作，但是，即使过了 10 分钟，它也没能在户外找到我们。

对于我们的实际测试来说，这并不是最好的条件，在一次自行车旅行中，我们将平板电脑与 Garmin Venu 2 智能手表进行了比较。事实上，Teclast T40 Air 确定的位置总是与我们实际骑行的路线略有偏差。

总之，我们没有发现任何严重的错误，这意味着如果不要求很高的精确度，这款平板电脑绝对可以用于定位。不过，它在应用程序测试中的失误以及在实际测试中的不太精确定位，让我们不敢轻易推荐它作为导航设备使用。

摄像头 - 即使对于平板电脑来说也很糟糕

你不应对 Teclast T40 Air 的摄像头抱有太高期望。许多平板电脑都将其视为省钱的地方--归根结底，这么大的设备不会优先考虑作为拍照设备，而很可能只是用来记录某些情况、扫描文件或扫描二维码。

为此，其配备 LED 闪光灯的 1300 万像素后置摄像头就足够了。另一方面，如果你期待拍出出色的照片，那么平板电脑的模糊照片会让你大失所望，因为它的照片无论在亮部还是暗部都缺乏动感。它的照片还带有浓重的蓝色色调，较大的区域往往颗粒感很强。在我们周围环境的照片中，你看不到太多细节，有些区域甚至非常不清晰。在对比度较高的弱光环境下，暗部仍然是暗的。

视频最高可录制 1080p 和 30 fps。

平板电脑正面配备了一个 800 万像素传感器，即使在光线良好的条件下也能拍摄出相当暗的照片。放大后，只能识别有限的细节，照片显得颗粒感很强。

该照相系统对于拍摄快照来说已经足够好了，但它甚至赶不上中档照相手机。

在我们的测试实验室中，Teclast T40 Air 的主摄像头甚至难以提供清晰的图像：它的对比度很低，一些区域看起来不干净，总之，照片看起来不是最好的。在只有 1 勒克斯照度的情况下，传感器无法显示任何可见内容。

配件和保修 - 制造商提供 12 个月的保修服务

Teclast 为其所有设备提供 12 个月的保修服务。

如有保修要求，制造商建议联系经销商进行维修处理。

T40 Air 随附一个充电器、一条 USB 数据线和一个 SIM 卡工具。Teclast 还提供带支架功能的透明保护套，网上售价约为 15 美元。

输入设备和操作 - 基本流畅

这款平板电脑的刷新率不会超过 60 赫兹，这意味着操作起来几乎感觉不到流畅。即便如此，Teclast T40 的反应还是可靠而灵敏的，我们只在运行较高强度的应用程序时才注意到它有些滞后。

顶部边缘的硬件按键很好找，按压点也很清晰。Teclast T40 没有配备指纹传感器，只有 2D 面部识别功能，这虽然不能完全防止人为操作，但仍能可靠地解锁平板电脑。

显示屏 - 看到蓝色了吗？

Teclast T40 Air 的显示屏尺寸为 10.36 英寸，分辨率为 2,000 x 1,2000 像素，采用 IPS 技术。它的最大亮度在同类产品中处于平均水平--我们测得的平均亮度为 296 cd/m²，主要适合在没有强光的室内使用。

在瞥一眼显示屏时，你确实会注意到蓝色色调。在 CalMAN 测试中，我们使用分光光度计证实了这一点。使用 T40 Air 的板载工具（尤其是夜光模式）可以稍稍缓解这种现象。不过，它的色彩描绘并不令人惊叹。

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

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 8743 (minimum: 5 - maximum: 343500) Hz was measured.

即使在最低亮度设置下，我们也没有注意到任何 PWM。

另一方面，它的反应速度非常慢，几乎不可能实现流畅的游戏。

Display Response Times

ℹ

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
33.1 ms ... rise ↗ and fall ↘ combined	↗ 14.5 ms rise
33.1 ms ... rise ↗ and fall ↘ combined	↘ 18.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 89 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
58.4 ms ... rise ↗ and fall ↘ combined	↗ 32.4 ms rise
58.4 ms ... rise ↗ and fall ↘ combined	↘ 26 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. » 94 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 ms).

在室外，显示屏在阴天时已经很容易反光，而且由于亮度较低，它的清晰度也不高。

即使从极端角度观看，显示内容的颜色也几乎不会发生变化。

性能 - 该价位的正常动力

产品Unisoc T616这是一款通常安装在中端平板电脑和手机上的 SoC，因此非常适合 Teclast T40 Air。该处理器的最高时钟频率可达 2 GHz，在基准测试中的表现与同类设备相差无几。

在日常使用中，只有在运行要求较高的应用程序时才会出现掉帧现象--浏览网页、查看照片或观看电影很少会出现掉帧现象。

ARM Mali-G57 MP1 GPU 只有一个运算核心，这让这款图形解决方案在玩要求苛刻的游戏时显得力不从心。即使是 3D 基准测试，在 1080p 分辨率下也无法以 30 帧/秒的速度流畅运行，而在 1440p 或 4K 分辨率下，每秒只能运行几帧。

Teclast T40 Air 的存储容量可能很大，但其 eMMC 闪存肯定不是最快的。不过，在这个价位的产品中，你几乎找不到比它更快的了。

因此，数据传输和加载时间可能需要一点时间。

游戏 - 3D 游戏中晃动的 30 fps

在 Teclast T40 Pro 上玩简单的游戏不成问题，大多数游戏都可以从 Google Play 商店下载--作为这款平板电脑的用户，你不会遇到任何限制。

不过，大多数游戏的帧数只能达到 30 帧，即使如此，也不是最流畅的。如果你的期望值不高，或者你只玩 2D 游戏，那么 T40 Air 就足够了。要玩有趣的 3D 游戏，您需要更好的图形处理能力。

我们本想公布详细的帧速率，但该平板电脑拒绝使用GameBench 软件正常工作。.

排放 - T40 Air 几乎不发热

温度

长时间使用后，平板电脑正面的温度最高可升至 33.9 °C，但这只是稍微明显。这意味着即使在炎热的天气和运行要求较高的应用程序时，手持平板电脑也不会有任何问题。

3DMark 压力测试也证明了这一点：当平板电脑长时间执行要求苛刻的任务时，处理器不会出现节流现象。性能最多会有轻微波动，但总能恢复到起始水平。

Teclast 平板电脑侧面的扬声器能产生不错的音效，即使在最高音量下也不会出现高音过重的情况。当然，平板电脑无法与真正的高保真音响系统相媲美，但听音乐或播放电影原声效果还是不错的。

还可以通过 3.5 毫米音频插孔或蓝牙连接外置扬声器或耳机。连接没有任何问题，无线播放所需的音频编解码器也一应俱全，包括 AAC、SBC、aptX、aptX HD 和 LDAC。

Pros

+ 良好的耐力

+ 大量存储空间和内存

+ 超薄金属外壳

+ 快速 microSD 插槽

+ 可使用移动数据

+ Android 13

+ 无 PWM

+ 不错的扬声器

Cons

- 定位服务不准确

- 摄像头系统非常弱

- 显示屏有强烈的蓝色调

- 屏幕太暗，无法在户外使用

- 更新不安全

结论：连接能力强，但也有不足之处

当然，Teclast T40 Air 也有不少值得批评的地方：例如，它的屏幕有很强的蓝色调、平板电脑的定位服务不准确以及摄像头非常弱等等。

与此同时，该设备也拥有许多积极的特性：它有大量的存储空间和内存，可以使用移动数据，有一个 microSD 插槽，对于模拟耳机爱好者来说，它甚至还有一个 3.5 毫米音频接口。

此外，T40 Air 的大容量电池带来了非常好的续航时间，而且不会让人感觉太重或太笨重。

由于这款平板电脑经常打折，而且屏幕暗淡、定位能力差，如果你打算在室内使用这款平板电脑的话，应该不会有太大问题，因此 Teclast T40 Air 还是值得考虑的。

Teclast T40 Air 的续航能力、移动数据支持和丰富的存储空间给人留下了深刻印象。不过，如果您正在寻找一款适合户外使用的明亮显示屏，那么您可能需要另寻他处了。

我们有几款可供选择的产品供您参考：这款Teclast M50 PrTeclast M50 Pr 的便携性更好，重量也更轻，但电池续航时间却不尽如人意。三星的Galaxy Tab A7 LTE 2022性能更好，但存储空间有限。
