外壳和设备 - 铝制底盘不时发出吱吱声
Teclast T50是一款拥有11英寸显示屏的平板电脑，售价260欧元。对于这样的价格，你得到了一个铝制的一体成型的底盘。我们的测试设备也有一个干净的表面，看起来很稳定，即使我们能激起安静的吱吱声。
角落很圆滑，T50的手感很好。它的重量并不轻，只有510克，但对其尺寸来说并不过分沉重。它还提供了比传统10.1英寸平板电脑更多一点的屏幕面积。
这款平板电脑只在中欧地区销售，配备了相对较少的8GB内存和128GB UFS 2.1大容量存储。然而，没有3.5毫米的耳机插孔接口，而且你也必须没有NFC，例如，用于移动支付交易。
microSD读卡器可以接受容量高达1TB的卡，但在使用时它会阻塞两个SIM卡插槽中的一个。在我们用参考卡Angelbird V60进行的测试中，读卡器似乎相当慢，而且在传输速度上也出现了明显的波动。

通信、软件和操作 - 纯粹的，但不完全是最新的Android
Teclast T50采用Wi-Fi 5作为最快的Wi-Fi标准。这款平板电脑的速度为298至379兆比特/秒，与这个价格范围内的其他平板电脑相当。在我们的测试中，传输速率也相当稳定。
这款平板电脑还可以接受两张SIM卡，并可以使用它们进行移动互联网接入。这以最大的LTE速度工作，并支持在欧洲运行的最必要的频率。
你还可以通过平板电脑拨打标准电话，但没有听筒，所以要么每个人都在听，要么你需要一个耳机。
Android 12是预装的，制造商几乎没有改变，所以用户界面的工作方式与许多其他设备一样。不幸的是，安全补丁有点老，即在测试时从2022年9月开始。至少，Teclast T50带有Widevine L1认证，所以你可以享受最高质量的流媒体。
这款平板电脑没有指纹传感器，但用户可以使用面部识别作为解锁设备的生物识别方法。由于大屏幕的余光，这种方法工作可靠，甚至在黑暗中也能工作，但由于对面部数据的纯软件评估，这种方法比较脆弱。

相机 - 平板电脑质量
Teclast在背面安装了一个带有索尼传感器的单摄像头。它的分辨率为2000万像素，对于一个廉价的平板电脑来说，在物体摄影方面显示出相当不错的图像清晰度。然而，动态范围还有待改进：黑暗区域几乎没有任何细节，而明亮区域则很快变得模糊。这在低光和高对比度的情况下尤其明显。
这种印象在测试实验室的照片中也得到了证实：在良好的工作室照明下的测试图看起来相当清晰，但明显曝光过度。在照度只有1勒克斯的情况下，照片中没有任何东西可以识别。
用户可以录制1080p和最多30帧的视频。自动对焦似乎时常有点力不从心，而亮度补偿有时也会出现延迟反应。然而，总的来说，如果要求不是太高，照片是可以使用的。
前面有一个800万像素的自拍相机。它拍摄的照片还不错，细节上看起来有点冲淡，但它们是可以使用的。

显示屏 - 明亮且无PWM
凭借2000 x 1200像素的分辨率，IPS显示屏呈现的内容相当清晰，即使是在Teclast T50相对较大的显示屏上。不幸的是，最大帧率只有60赫兹。Teclast在其网站上提到了 "120赫兹采样率"，但这可能是指触摸屏的采样率。
这款平板电脑在亮度方面表现不错：我们测得的平均亮度为417cd/m²，比其他便宜的平板电脑提供的亮度要高得多，对于明亮的室外天来说可能不够，但至少对于光线充沛的客厅来说是足够的。
不幸的是，0.5cd/m²的黑值相对较高，所以黑暗区域看起来相当灰暗，面板上的颜色也不那么亮丽。在我们用分光光度计和CalMAN软件进行的测试中，灰度中可以看到轻微的蓝色偏移。然而，颜色基本上是以良好的精度再现的。
我们没有注意到PWM的闪烁。

性能、排放和电池寿命 - 强大的扬声器
淘宝网 Unisoc T616Unisoc T616是一个主频高达2GHz的SoC，对于较简单的任务来说完全够用，而且还能在Teclast T50的菜单中进行相当流畅的导航。然而，多任务处理或更复杂的应用程序有时会给系统带来挑战，一些输入只能通过延迟实现。在这个价格范围内有一些更快的设备，特别是在图形性能方面。
然而，存储速度是一个真正的亮点，因为Teclast T50的UFS 2.1闪存可以超越所有同等价位的对手。这也经常导致上网时的流畅体验。
即使在高负荷情况下，高达34℃的发热也几乎不明显。3DMark的压力测试结果也与此相符，在长时间的负载下也没有显示出性能下降。
Teclast T50配备了四个扬声器，在我们的测试中不是特别响亮，但声音很好。它不包含任何深沉的低音，但能有力地再现深沉的中音。扬声器即使在全音量下也不会过载，可以听到人声和乐器的相当多的细节。
用户还可以通过USB-C或蓝牙5.0连接外部音频设备。然而，支持的音频编解码器的种类有点有限，特别是更现代的变体：SBC、AAC、aptX、aptX HD和LDAC都可用。
这款平板电脑配备了一个容量相对较高的7500毫安时电池。电池寿命很好，我们在Wi-Fi测试中确定的时间略低于15小时。然而，其他电池容量小得多的平板电脑也能达到类似的运行时间，因此Teclast T50在效率方面可能仍有一些需要追赶的地方。
最大充电功率为18瓦，并包括一个相应的电源。因此，直到平板电脑再次充满电，可能需要3个小时。不支持无线充电。

Pros

结论 - Teclast平板电脑令人信服
Teclast T50具有良好的性价比，拥有大量的快速内存，明亮的屏幕以及良好的运行时间，甚至还支持LTE。这款平板电脑并不是一个非凡的设计亮点，但它的制造质量很扎实，它带给买家的是相当纯粹的Android 12。
相机不能满足苛刻的用户，但对于平板电脑来说，它们是可以的。你会徒劳地寻找一个指纹传感器和一个3.5毫米的音频端口。蓝牙编解码器的选择也有些有限。
作为回报，安装的四个扬声器具有很高的音量，并提供良好的音质。Teclast仍然可以在效率上下功夫；这款平板电脑的大电池可以实现更好的运行时间。对于这样一个巨大的电池来说，更快的充电技术也是一件好事，但另一方面，问题是你是否会经常带着一个超过500克的平板电脑远离电源插座。
Teclast T50以相对较少的钱配备了非常好的设备。
如果你想选择更成熟的制造商，你可以通过以下产品获得更好的平板电脑 联想Tab M10第三代但必须在屏幕亮度和软件方面做出让步。这款 Blackview Tab 13甚至更便宜，但它有令人讨厌的、无法卸载的光顾性应用程序。
价格和可用性
在中欧，Teclast T50是通过amazon.de出售的。出售，目前可以在那里找到约200欧元的折扣。
