机箱和功能 - 金属机箱不时发出吱吱声
我们测试的 Oukitel OT8 采用灰色金属边框，背面也是同色金属材质。相机模块上有两个巨大的开口，并有闪亮的红色装饰。后面只有一个小得多的相机镜头和 LED 闪光灯。
设计看起来很现代，正面屏幕的边缘也不宽。这意味着你仍然可以舒适地将平板电脑握在手中，而不会经常不小心触碰到触摸屏。
外壳的稳定性相当一般：如果你稍稍扭动平板电脑，就会听到明显的咔嗒声，屏幕模块有时也会在边框下轻微移动。不过，就该价位而言，其硬度尚可，做工也不错。
这款平板电脑配置了 6GB 内存，与同价位平板电脑相比相当充裕。256 GB 的大容量存储空间在这个价位的平板电脑中也很少见。虽然没有 NFC 功能，但有两个 SIM 卡插槽，这意味着可以使用移动网络上网甚至打电话。
microSD 插槽与 SIM 卡共享一个插槽。在这里，您必须决定是使用双 SIM 卡还是 SIM 卡和 microSD 卡。总体而言，读卡器与我们的 Angelbird V60 参考卡配合使用时，在传输速率方面达到了同类产品的领先水平。不过 三星Galaxy Tab A9+显示了更高的数据传输速率。

通信、软件和操作 - 支持 LTE
该平板电脑提供的 WiFi 5 是最快的标准。在我们使用华硕 ROG Rapture AXE11000 参考路由器进行的测试中，Wi-Fi 的数据传输速率约为 300 - 350 MBit/s，而且相对稳定，即使在多次重复测试后也是如此。平板电脑无法完全利用千兆互联网连接，但 WLAN 的速度足以满足日常使用，无需大量下载。
LTE 网络也可用于上网，而且有多个频率可供选择。不过，如果要去更远的地方，尤其是美国或墨西哥，应检查平板电脑是否支持相应的频段，Oukitel 也在其网站上推荐了相应的频段。在我们的测试中，市区的接收效果不错，但还达不到高端智能手机的水平。
制造商在平板电脑上安装了Android 13，几乎没有对系统做任何改动。测试时的安全补丁是从 2023 年 11 月开始的，因此比较旧。没有预装第三方软件。幸运的是，该平板电脑支持谷歌的 DRM 标准 Widevine L1，因此可以不受分辨率限制地观看流媒体服务。
虽然触摸屏的最大采样率只有 120 赫兹，显示屏每秒最多只能显示 60 帧画面，但操作仍然相当流畅。系统性能较低，解锁时偶尔会出现等待时间，这也是一个比较大的障碍。
包装中还附带了一支手写笔，不过这只是被动型，即没有与设备进行蓝牙连接。使用它可以比用手指更精确地进行输入和导航。不过，没有压力级别识别功能，例如，在绘画和绘图应用程序中无法识别不同的笔触。
这款廉价平板电脑没有指纹传感器，但可以通过前置摄像头进行面部识别。该功能没有红外传感器，因此不像更昂贵的解决方案那样安全。不过，一旦存储了人脸，它就能可靠、快速地工作。

摄像头 - 自拍摄像头能拍出不错的照片
平板电脑背面有一个 1300 万像素的摄像头。它拍摄的照片并不十分细腻，清晰度也不高。随着光照强度的减弱，暗处的细节会越来越模糊，而其余光源则会变得更加清晰。
视频最高可录制 1080p 和 30 fps。自动对焦有时需要很长时间才能适应不断变化的环境。曝光补偿也不是最快的。总的来说，视频的色彩不是很丰富，很快就会出现模糊和不美观的情况，尤其是在光线不是很好的情况下。
自拍摄像头隐藏在正面屏幕上方的边框中。拍摄出来的照片可以使用，但放大后很快就会发现照片上有粗糙的颗粒。除此之外，细节还原还算不错。

显示屏 - 不太亮
该机采用 11 英寸显示屏，全高清分辨率略微扩大为 16:10 格式，屏幕尺寸与同价位平板电脑相当。不过，最大亮度不到 400 cd/m²，这使得该设备不如三星或小米。
只要在室内，这通常不是大问题，但在花园或室外的咖啡馆，显示屏上的反光会让人难以看清屏幕内容。
即使在亮度很低的情况下，我们也没有发现 PWM 闪烁。在使用分光光度计和 CalMAN 软件进行的测试中，我们发现显示屏有明显的偏蓝现象，尤其是明亮的蓝色和绿色色调失真严重。总的来说，色彩显得有些暗淡。

性能、排放和电池寿命 - 最好能有更大的功率
产品 Unisoc T606Unisoc T606 并不是众所周知的性能冠军，通常用于价格非常低廉的手机和平板电脑。这意味着 Oukitel OT8 通常只能排在比较领域的末尾。图形性能也很低，因此游戏玩家应该另寻他处。
另一方面，内存的速度却出人意料地快：制造商采用了 UFS 2.2 闪存，许多中端手机也采用了这种技术，因此平板电脑的性能明显优于对比设备。由于处理器速度较慢，因此也无法实现快速加载，但快速的内置内存至少可以稍稍弥补不足。
在长时间负载的情况下，机壳表面几乎不会出现明显的发热现象，3DMark 压力测试也显示其性能保持在非常稳定的水平。
平板电脑有四个扬声器，音量相当大。整体听起来也不错，甚至可以听到一些中低音。外部音频设备也可通过 3.5 毫米插孔或蓝牙 5.0 连接。无线音频传输还支持 aptX HD 和 LDAC 这两种更高质量的编解码器。
电池容量为 8800 毫安时，容量非常大，在我们的 WLAN 测试中也达到了 18 小时以上的良好运行时间。这意味着在雨天使用 Oukitel OT8 时无需充电。如果平板电脑确实需要插电，可以使用高达 18 瓦的功率充电；充满电大约需要 4 个小时。

Pros
Cons
结论 - Oukitel 平板电脑功能出色
Oukitel OT8 在 200 欧元以下的价格范围内有几个亮点：首先，它拥有超大、超快的大容量存储空间，并由 6 GB 内存提供支持。Android ，时尚的金属外壳，2 个 SIM 卡插槽支持移动网络。四个扬声器提供了良好的音效，电池的续航时间也很长。
不过，事实证明这款平板电脑在某些方面也令人眼花缭乱：例如，制造商声称有 30 GB 内存，但只能通过内部存储器中的 24 GB 交换文件来访问。不过，这样做相对较慢，对绝大多数用户来说可能没有必要。此外，随机附带的手写笔并不是我们从更昂贵的平板电脑上了解到的那种手写笔，而只是一种支持更精确输入的辅助工具。
除了超快的内存外，平板电脑的性能显然有限，只能满足基本的日常使用。摄像头也是临时拼凑的，只有前置自拍摄像头的效果尚可。
Oukitel OT8 功能丰富，运行时间长。不过，这款平板电脑的性能储备并不多。
三星 三星Galaxy Tab A9+速度更快，还能保证 4 年更新。不过，它的内存较小。
价格和供应情况
Oukitel OT8 可直接从制造商处购买，价格不到 160 欧元。
在亚马逊网站（amazon.de）上，这款平板电脑的测试价格为 199 欧元，但您可以兑换一张 20 欧元的代金券。
