外壳和连接性 - 金属外壳和大量存储空间
中国制造商 Cubot 的 Tab 50 售价约为 200 美元，但你很可能在网上找到更便宜的价格。在这个价位上，很多平板电脑都在争夺潜在买家的注意力，因此我们想仔细看看这款经济实惠的设备。
与同价位产品相比，它的外壳给人的感觉相当高质：它有一个灰色金属背壳和一个金属边框。只有背面顶部有一个闪亮的蓝色塑料插件，有助于改善无线局域网和蜂窝数据的天线连接。背面还有两个相机镜头，其中一个只是装饰，没有实际功能。
这款平板电脑的尺寸为 10.4 英寸，介于两者之间，非常有趣：它比 11 英寸平板电脑稍轻、更小巧，但与此同时，它的显示屏面积比 Oukitel OT8的 10.1 英寸屏幕相比，它的显示面积要稍大一些。
平板电脑屏幕周围的边框大小适中，使其看起来既现代又舒适，不会误触触摸屏。平板电脑非常稳定，几乎无法扭动。
256 GB 的存储容量相当大，8 GB 的内存也很宽裕。绝大多数用户都会觉得够用，但如果不够用，你还可以选择激活 8GB 虚拟内存。虚拟内存是在速度明显较慢的数据内存中以交换文件的形式创建的，因此不太可能带来重大优势。
在内部，USB-C 端口是通过 USB-2.0 连接的，因此无法实现与其他设备的快速数据传输。如果要连接外部音频设备，可以使用平板电脑一角的 3.5 毫米音频插孔。遗憾的是，它不支持用于非接触式支付的 NFC 功能。
microSD 读卡器占据了两个 SIM 卡插槽中的一个。而它的运行速度也相当快：在复制测试中，我们测得的数据传输速率为 42.5 MByte/s。虽然我们没有充分利用 Angelbird V60 microSD 卡的最大数据传输速率，但 Cubot Tab 50 的表现仍然比许多同价位平板电脑要好得多。

通信、软件和操作 - 稳定的无线局域网和 LTE 调制解调器
在无线局域网测试中，我们测得的数据传输速率相对稳定，在 300 - 350 MBit/s 之间。这表明它使用的是 WiFi 5 调制解调器，通过快速查看平板电脑的规格表和我们的系统信息应用程序可以证实这一点。
因此，这款平板电脑的性能处于同类产品的平均水平，但它的传输速率非常稳定，甚至比一些同价位的设备略快。即使离路由器很远，中间隔着三堵墙，它的信号质量也还可以--不过，网页加载速度要比紧靠路由器时慢得多。
Cubot Tab 50 还可以使用蜂窝数据访问网络和拨打电话。这需要使用 nano-SIM，不支持 eSIM。我们测试设备的 LTE 网络种类有限，仅能满足中欧地区的需求，我们的测试就是在中欧地区进行的。因此，如果你想带着这款平板电脑去旅行，应该先了解清楚目的地是否能上网。
Android 这款平板电脑预装了 13，制造商几乎没有对其进行过改动。在测试时，它的最新安全更新是 2023 年 11 月的，所以已经很老了。制造商没有承诺任何更新，所以你只能期待不定期的安全补丁。至少，你可以得到非常纯净的 ，没有任何可能令人讨厌的第三方应用程序。Android
它的触摸屏反应不是很灵敏，但使用起来很方便。它的边角也很灵敏。Tab 50 没有提供指纹传感器或面部识别解锁选项。这意味着在银行应用程序等中也无法使用该选项进行身份验证。

照相机 - 质量差
背面有一个 1300 万像素的单摄像头。如果需要，至少还配有 LED 闪光灯。
遗憾的是，在光线非常暗的情况下，该摄像头被证明是完全失败的；在正常的日光下，图像只能稍微变亮。同时，非常明亮的区域很快就会曝光过度，只能捕捉到很少的细节。
当然，你不应该对平板电脑的摄像头抱有太高期望，但 Tab 50 的图像质量确实只能满足在光线良好的条件下拍摄最基本的快照。
前置摄像头拍摄的自拍照模糊不清，在暗处几乎无法辨认出任何细节。

显示屏 - 明显的蓝色色调
平板电脑屏幕的分辨率为 2,000 x 1,200 像素，10.4 英寸的屏幕可清晰显示图像。它的最大亮度为 308 cd/m²，仅够在室内使用；在室外，周围环境的反射很快就会妨碍你查看图像内容。
在使用分光光度计和 CalMAN 软件进行测量时，我们发现其显示屏上有很强的蓝色色调，使色彩显得相当冷淡。由于其色彩偏差较大，你不应该依赖屏幕来显示真实的色彩。
我们没有注意到任何 PWM 闪烁，即使在低亮度下也是如此。

性能、排放和电池续航时间 - 为大量应用程序提供动力
Cubot Tab 50 采用 联发科 Helio G99作为 SoC，这在同价位产品中是相当强大的芯片。因此，它的基准测试成绩明显高于对比设备，而且该设备在处理器和图形处理方面的性能明显更高，也就不足为奇了。
这意味着该系统使用起来相当流畅，而 UFS 2.2 存储系统的良好传输速率也功不可没。
即使在长时间负载的情况下，平板电脑外壳的最高发热温度也仅为 33 °C，因此在使用时不会出现任何问题。正如 3DMark 压力测试显示的那样，SoC 在长时间负载下也不会出现节流现象。
Cubot Tab 50 有四个扬声器，因此可以达到很好的最大音量。不过，它们的声音并不特别饱满。中低音几乎听不到，声音比较平淡。
可通过 3.5 毫米音频插孔或蓝牙连接的外置音频设备的音质要好得多。所有重要的编解码器都可用于无线音频传输，包括 LDAC 和 aptX HD 等高保真编解码器。
Cubot Tab 50 的电池容量为 7500 毫安时，属于中等水平。在我们的无线局域网测试中，Cubot Tab 50 的续航时间为 14:04 小时，这意味着它可以在雨天轻松地在家娱乐。由于配备了 18 瓦的电源，充电时间并不长，但如果电池完全耗尽，则需要等待 4 个小时才能充满电。

Pros
Cons
评价：速度快，设备齐全，但不完美
Cubot Tab 50 凭借其强大的 SoC 处理器，在众多廉价平板电脑中脱颖而出。它的电池续航时间也不错，金属外壳令人印象深刻，大容量存储空间和手机支持功能也很强大--因此，该设备可以推荐给那些以花很少的钱购买快速平板电脑为主要目的的用户。
不过，那些追求其他品质的用户也不得不接受一些失望：例如，它的摄像头实际上只适合扫描二维码或在紧急情况下拍照。它的扬声器没有充分利用可用的声音空间，只能发出比较平淡的声音。它的安全补丁也相当老旧，你应该期待不定期的更新。如果你想通过指纹或面部识别来保护平板电脑上的数据安全，那也只能另寻他处了。
不过，有些东西我们还是不能不提的，那就是相对较快的 microSD 读卡器、稳定的 WLAN 信号和较低的温度。因此，Cubot Tab 50 的性能有好有坏，你应该在购买前考虑一下哪些功能对你来说是最重要的。
Cubot Tab 50 得益于快速处理器和 LTE 支持。另一方面，如果你正在寻找明亮的显示屏和可用的摄像头，那么你会有点失望。
快速浏览一下替代产品：Teclast M50 HD Teclast M50 HD同样小巧，同样配备 LTE 调制解调器。红米 红米 Pad SE采用 90Hz 面板，但性能远不及我们的测试设备。
价格和供应情况
Cubot Tab 50 应该很快就能在制造商的亚马逊商店买到。它的零售价可能在 200 美元左右。
