外壳和连接性 - 一个简单的塑料外壳,却蕴含着惊喜

对于 PocketBook 的粉丝来说,这款电子阅读器略显朴素的外壳一眼就能辨认出来,这要归功于其背面触感极佳的条纹印花。它的颜色叫做 "Stormy Sea"(暴风雨之海),可以说是由深灰色调组成。外壳由塑料制成,做工精良,但背面在受力时会有轻微凹陷。

操作按钮位于电子阅读器的长边--这也是外壳边框略宽的特点,使读者可以舒适地握住设备,而不会意外启动触摸屏。Era Color 重量仅为 195 克,体积很小,非常便于携带,可以轻松装进更小的包里。

如果电子阅读器在游泳时不小心掉进湖里,也不用担心:Era Color 的防护等级为 IPX8,这意味着它可以浸入淡水中几分钟。

对于电子阅读器来说,1 GB RAM 已经足够。不过,如果你经常上网,那么你只需确保不会意外退出浏览器即可:由于设备的 RAM 较小,应用程序不会在后台保持打开状态,因此每次返回时都会重新启动。

32 GB 的存储空间为用户提供了足够的电子书空间,你还可以利用 PocketBook Cloud 在线存储更多内容。遗憾的是,你不能插入任何 microSD 卡来扩展存储空间或传输文件。此外,当通过 USB-C 端口将阅读器连接到电脑时,阅读器在使用哪种线缆才能识别设备和传输文件方面有些挑剔。

我们最喜欢的地方阅读器背面的挡板后面有几个 Pogo 插针,可以用来将附件连接到阅读器上。例如,这包括一个充电盖,它可以让你以无线方式为设备充电。

通信、软件和操作 - 包括电子书店

Era Color 的上网速度并不快:WiFi 4 是它支持的最快标准。这只能带来大约 55 MBit/s 的速度,对于下载普通书籍来说可能足够了,但如果你要下载较大的有声读物,这可能要花费一些时间。

它的软件基于 Linux,与Android 相比各有利弊:你可以使用直接集成的商店,因为制造商无需向谷歌支付任何费用(与Android 不同)。该商店提供广泛的选择,包括多种语言的最新版本。同时,你不能安装任何应用程序来扩展电子阅读器的功能。

除了阅读电子书外,您还可以记笔记和上网,此外,您还可以访问日历、RSS 新闻阅读器和一个可将设备用作数码相框的应用程序。还支持图书馆在线借阅。您可以通过 Dropbox、内部的 PocketBook Cloud 或直接通过电子邮件将电子书籍发送到设备上。此外,还预装了多款游戏和绘画功能。

你可以通过触摸屏操作电子阅读器,不过有时反应会有点慢。这一方面是由于电子墨水技术加载内容需要时间,另一方面也与 Era Color 的性能有限有关。

除了屏幕,用户还可以通过四个硬件按钮来操作阅读器:你可以翻阅菜单,更重要的是翻阅书籍,启动待机模式或返回主屏幕。从触觉上讲,这些按键可以更好地分开,而且它们的标签没有触感,也不是特别明显。

电子阅读 - 多种格式和功能

PocketBook Era Color 支持多种格式,包括 CBR 和 CBZ 电子漫画格式。还可以阅读 Kindle AZW 和 AZW 3 格式,但前提是内容不受版权保护。您还可以阅读以下格式的电子书:ACSM、CHM、DJVU、DOC、DOCX、EPUB、EPUB(DRM)、FB2、FB2.ZIP、HTM、HTML、MOBI、PDF、PDF (DRM)、PRC、RTF 和 TXT。

如果你点击一本书,预装的电子阅读软件就会自动启动,允许你对阅读体验进行大量调整:你可以分三步选择行距,还可以选择到屏幕边缘的间隙应该有多大。如果字与字之间不分隔,也可以进行选择。

您可以在 20 种字体中进行选择,并将其中一些字体显示为斜体或粗体。还可以设置或完全隐藏显示的页数。如果不知道某个术语,可以做笔记或查字典。

如果需要,还可以使用语音合成功能朗读 26 种不同语言的文本。你不要指望它能达到专业有声读物的质量,因为它的语音语调经常不正确,而且系统在处理新创建的单词时也很吃力。但对于无障碍阅读和应急解决方案来说,这是一项不错的功能。

显示屏 - 彩色显示屏的明亮照明

显示屏的显微图像
显示屏的显微图像

长宽比为 4:3 的 7 英寸显示屏是一款方便的电子阅读器。不过,喜欢大字体的用户会发现使用空间更大的显示屏会更方便,因为在 Era Color 上需要频繁翻页。

显示屏基于 E-Ink 的 Kaleido 3 面板,可显示 4,096 级色彩和 16 级灰度。其分辨率取决于所显示的内容:灰度可显示 1,872 x 1,404 像素,而彩色只能显示一半。

这也是由于电子墨水显示屏所采用的特殊技术,因为微小的墨水颗粒实际上是通过电荷定位的。彩色滤光片用于显示不同的色调,从而降低了分辨率。电子阅读器的色彩显示强度一般,但我们发现 InkPad Color 3 的色彩显示强度更高。

电子墨水显示屏需要照明,以便在光线不足的条件下也能阅读。PocketBook Era Color 的亮度可达 92 cd/m²,绝对够用。色温和亮度都可以进行多级调节或由设备自动调节。

由于采用的是 PWM 技术,因此无需担心闪烁问题,我们在使用示波器进行测试时也没有发现任何闪烁现象。图像一旦生成,就会一直显示在屏幕上,不需要额外的电源,这对眼睛和阅读器的电池都很方便。

不过,电子墨水显示屏也有其缺点:只能显示相对较少的色彩细微差别。页面加载时间相对较长,几乎无法查看移动图像,而且对输入的响应速度较慢。屏幕上时不时会残留前一幅图像的影子。

Screen Flickering / PWM (Pulse-Width Modulation)

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 8705 (minimum: 5 - maximum: 343500) Hz was measured.

性能、排放和电池寿命--在小巧的设备上轻松阅读

我们很难客观地判断 PocketBook Era Color 的性能有多强大,因为只有浏览器基准测试在专有的 Linux 系统上运行。不过,测试结果表明,其他电子阅读器的性能有时要强得多。该设备使用四核处理器,提供 4 x 1.8 GHz 的计算速度。不过,制造商没有说明使用的是哪种型号。

我们遇到过页面加载速度更快的电子阅读器,但如果你主要想在 Era Color 上阅读,那么它的性能就足够了。反过来,你会发现 Era Color 的速度经常会落后,你必须预留等待时间,尤其是在浏览器应用程序和输入文本时。

不必担心外壳会明显发热;即使长时间使用,我们也几乎没有发现温度升高。

底部边缘的扬声器可以让你收听有声读物和音乐。声音可以清晰地再现,但听起来总是有些遥远。遗憾的是,它缺乏深度和低音,声音不够饱满。耳机或扬声器可以通过 USB-C 端口(可能还需要一个合适的适配器)或蓝牙连接。传输的声音信号非常清晰。

就阅读器的大小而言,2500 毫安时的电池容量并不算大。不过,在屏幕亮度较低的情况下,它仍能支持 14:46 小时的阅读时间。通过数据线充电需要时间:您最多需要 2:30 小时才能充满电。无线充电时间更长。

评价:一款具有独特功能的小型电子阅读器

PocketBook Era Color 评论。测试设备由德国 PocketBook 提供。
PocketBook Era Color 评论。测试设备由德国 PocketBook 提供。

PocketBook Era Color 是所有漫画爱好者和有大量插图书籍(如烹饪书)爱好者的不二之选:这正是彩色显示屏的真正优势所在。Era Color 的阅读时间超过 14 小时,雨天也能轻松度过,而且其小巧的外形使其成为一款防水的简易伴侣。

就性能和无线局域网速度而言,如果你花更多的钱,肯定还有更强大的电子书阅读器。不过,它所提供的功能足以满足日常使用,尤其是阅读这一核心功能。它的阅读软件功能丰富,你可以通过制造商的商店直接在设备上购买书籍,然后直接开始阅读。

此外,该设备还配有扬声器和连接耳机的选项,因此您还可以欣赏有声读物或音乐。您甚至还可以选择通过盖子进行无线充电,这也是它的独特之处。

PocketBook Era Color 是一款超级小巧的电子阅读器,无需使用实体按键。

 

如果你不需要 Era Color 的彩色屏幕,那么你也可以选择黑白屏幕的版本,这样可以节省一些费用。如果你正在寻找一个更灵活的系统,那么你可以考虑基于Android 并支持应用程序的电子阅读器,如Onyx Boox Page

价格和供应情况

这款电子阅读器目前可在亚马逊上购买,售价259 美元
