外壳 - 带有塑料部分的铝制平板
Teclast用铝合金和塑料制造了T40 Plus的外壳,这使该设备看起来相对优质。在背面,不同的材料以不同的颜色相互突出,但过渡是均匀的。总的来说,制造质量很好。
然而,我们测试机型背面的相机传感器在镜头下没有居中,这对图片质量有负面影响。然而,我们无法判断这种缺陷是否经常发生。
在制造商提供的图片中,显示屏周围的边框看起来比实际情况要窄一些。这款平板电脑也比图片上看起来更厚。然而,实际尺寸与这个价格范围内的其他设备一致,而且只有455克(约16盎司),Android ,相对来说比较轻。
功能 - 插孔和微型SD
微型SD卡读卡器
T40 Plus中安装了一个microSD读卡器,当用我们的参考存储卡AV Pro V60复制数据时,它只能达到26.36MB/s的低速。当插入microSD卡时,它也会阻塞第二个NanoSIM插槽。

软件--纯净Android
通信和GNSS - 使用LTE和WiFi移动5
Teclast的平板电脑可以通过GSM、3G和LTE建立移动连接。安装的SoC支持LTE,下行支持Cat.7,上行支持Cat.4。4,从而使速度达到300MBit/s(下载)和50MBit/s(上传)。还可以使用VoLTE,这意味着这款平板电脑也适用于打电话。
蓝牙5.0和WiFi 5可用于近距离的无线连接。通过我们的参考路由器Netgear Nighthawk AX12,我们在传输过程中实现了305MBit/s的速度,在数据接收过程中实现了327MBit/s的速度。因此,Teclast T40 Plus与我们的测试领域不相上下。

照相机--传感器不完全对中
Teclast为T40 Plus配备了一个800万像素的主摄像头和一个500万像素的前置摄像头。后者拍摄的人像照片对比度较弱,即使在光线很好的情况下也显得太暗和模糊。主摄像头显示我们的测试对象色彩苍白,细节水平适中。图片右侧的黑色散射是由相机传感器造成的,在我们的测试模型中,传感器并不是位于镜头后面的中心位置。我们的全景拍摄也表明,相机不能很好地应对不均匀的照明条件。当放大时,主体看起来很浑浊,在低光照的图像中几乎看不到任何东西。除了打开HDR模式的选项外,对图像质量没有其他调整。
视频记录显示出与我们的测试照片类似的质量。主摄像头支持480p、720p和1080p分辨率,而前置摄像头支持480p和720p。没有关于帧数的信息,也没有任何手动设置。
在受控的照明条件下,Teclast T40 Plus记录的ColorChecker护照太亮了。测试图还清楚地显示了角落里的对比度弱点,据此,图片中的右侧又受到了歪斜的相机镜头的影响。


附件和保修 - 包括盖子
T40 Plus配备了一个USB电源适配器,配有配套的USB-C电缆,一个SIM卡针,以及一个保护罩,该保护罩还可以折叠在显示屏上,作为支架使用。
Teclast给予12个月的保修期。
输入设备和操作 - 良好的触摸屏
显示屏 - 明亮且无闪烁
Teclast T40 Plus的屏幕由10.4英寸IPS面板组成,分辨率为2000 x 1200像素。亮度传感器并不存在。
最大的可调节亮度处于高水平,平均为486cd/m²。92%的照度也非常好。我们在APL50测试中测得的最高亮度为477cd/m²,最低亮度水平相当高,为39.9cd/m²。
亮度控制不依赖于使用 PWM.

Cons
结论 - 适用于日常使用
在我们的测试中,Teclast T40 Plus被证明是一款用于简单日常应用的廉价平板电脑。构建质量基本上是好的,但个别设备可能存在缺陷,正如我们的测试模型背面的相机传感器滑落所示。耳机插孔和128GB的内部存储以及LTE完善了原本稀少的设备包。
由于显示效果好、电池寿命长和价格低,Teclast T40是一款适合日常使用的平板电脑。
然而,非常好的电池运行时间和明亮的显示屏也很适合日常使用。由于后者是无PWM的,色彩还原相对较好,所以也很适合敏感的眼睛。如果内部存储不够,你还可以通过microSD卡进行扩展。
在价格低廉的平板电脑中,Teclast将T40 Plus与 三星Galaxy Tab A7 LTE和 联想Yoga Tab 11.然而,那些能多花点钱的人很快就会以 Apple iPad 10.2作为一个强有力的替代品。
价格和可用性
Teclast T40 Plus目前只能从Amazon(DE),但也可以通过AliExpress订购,例如.
