罗技 K480 多设备键盘(Logitech K480 Multi-Device Keyboard)拆箱
罗技蓝牙多设备 K480 键盘(Logitech Bluetooth Multi-Device K480 keyboard)采用漂亮的浅色盒子，产品展示在正面。
在盒子的背面，我们找到了多种语言的技术规格。
在盒子里，我们找到了键盘、预装的两节AAA电池、(AAA)用户文档(user documentation)和一张带有产品页面(product page)链接的纸。我们发现专用于移动设备的键盘不使用可充电电池很奇怪。
包装真的很简单，没有那么吸引人，但这不是很重要的事情，不是吗？
硬件规格
乍一看，您会发现罗技 K480 蓝牙多设备键盘(The Logitech K480 Bluetooth Multi-Device keyboard)与超薄 Apple 键盘(Ultrathin Apple keyboard)或其他纤薄产品不同。重量为 820 克（1.807 磅）和 20 毫米（0.78 英寸）厚的罗技 K480(Logitech K480)显然不是最便携的键盘，可以轻松放入您的行李中，但它在效率上有所弥补。
它的全尺寸为 195 x 299 x 20 毫米或 7.67 x 11.77 x 0.78 英寸（高 x 宽 x 深(Height x Width x Depth)），如您所见，它比任何其他类似产品都大。这使其成为在办公室工作并使用多种(office and use multiple)移动设备的人的完美小工具。无线键盘(devices.The wireless keyboard)有两种颜色：白色和黑色。我们为这次审查展示了白色模型，但我个人更喜欢黑色模型。如您所见，键盘完全由塑料制成，除了由硅胶制成的键盘腿，以便在光滑的表面上更好地稳定。
在板的上边缘，功能键(function keys)上方，是一个橡胶槽。旨在(Meant)充当展示架(display stand)，它运行键盘的宽度。它旨在容纳与 10 英寸 (258 毫米) 平板电脑一样大的移动设备。支架以舒适的 50 度角放置手机和平板电脑，如果两者都以纵向模式(portrait mode)放置，它的宽度足以将平板电脑与智能手机放在一起。
这个弯曲的键盘显示了间隔良好的圆形键、深度行程和体面但略带糊状的响应。K480(The K480)打字舒适，一旦您将手放在上面，就会提供令人愉悦的触觉反馈。(tactile feedback)按键排列专为多种操作系统设计，带有适用于Windows 和 MacOS的“ (Windows and MacOS)Alt ”和“ Cmd ”键。对于移动设备，顶行键提供了Android和 iOS 设备上的Home和Back键的快捷方式。
在这方面，罗技(Logitech)还有一些工作要做，因为命令键对于某些受支持的发行版并不完全有效。K480 键盘(The K480 keyboard)使用蓝牙(Bluetooth)建立设备之间的连接，它最多可以配对三个使用以下操作系统(operating system)的设备：Windows、Chrome-OS、Android、Mac OS 和 iOS(Mac OS and iOS)。您可以在此处找到键盘的全套规格：蓝牙多设备键盘 K480(Bluetooth Multi-Device Keyboard K480)。

在键盘的左上方，您可以看到一个带有三个切换位置的拨盘。转盘的每个位置表示键盘和移动设备之间的配对连接(pair connection)。如果您在第一个频道上有配对设备，但要添加另一个，只需更改频道并重复我们描述的步骤前。当您从一台设备切换到另一台设备时，您可以立即在当前设备上继续打字，这就是为什么我认为罗技(Logitech)团队在此功能上值得祝贺的原因。
假设您乘火车旅行，并且设置了Logitech K480 键盘(Logitech K480 keyboard)和平板电脑来处理项目以打发时间。您会听到智能手机的蜂鸣声，您会看到最好的朋友发来的短信，然后你们两个开始对话。接下来你知道的是，你正在从在平板电脑上工作，转向在智能手机的小键盘上写文本，这是一个令人讨厌的循环。好吧(Well)，我们有一个解决方案。您只需切换频道，连接手机（除非它是Windows Phone），然后：瞧！您现在可以通过在几秒钟内在两个设备之间切换来节省时间和精力。(time and nerves)我知道！酷(Cool)吧？

Reviewing The Logitech K480 Bluetooth Multi-Device Keyboard
Logitech is a brand that's known for its innovative gaming products, mainly PC peripherals, along with mobile and PC accessories. One of their newest products is the Bluetooth Multi-Device K480 keyboard, which promises to work with any smartphone, tablet or device that's equipped with Bluetooth. We've tested the keyboard for more than a week and we would like to share our findings in this review:
Unboxing The Logitech K480 Multi-Device Keyboard
The Logitech Bluetooth Multi-Device K480 keyboard comes in a nice light colored box, with the product displayed on the front.
On the back of the box we found technical specifications, in multiple languages.
Inside the box, we found the keyboard, two AAA batteries pre-installed, the user documentation and a piece of paper with the link to the product page. We found it odd that a keyboard dedicated for mobile devices doesn't use a rechargeable battery.
The packaging is really simple and not that attractive but that's not something that matters a lot, is it?
Hardware Specifications
On first sight you can see that The Logitech K480 Bluetooth Multi-Device keyboard is not like the Ultrathin Apple keyboard or other slim products. Weighing 820 grams (1.807lbs) and 20 millimeters (0.78inches) thick, the Logitech K480 is obviously not the most portable keyboard that can easily fit in your luggage, but it compensates in efficiency.
Its full dimensions are 195 x 299 x 20mm or 7.67 x 11.77 x 0.78 inches (Height x Width x Depth) and, as you can see, it's bigger than any other similar products. This makes it the perfect gadget for people who work in an office and use multiple mobile devices.The wireless keyboard comes in two colors: white and black. We are presenting the white model for this review, but I personally prefer the black one. As you can see, the keyboard is made entirely out of plastic, except for the keyboard legs that are made from silicone for better stabilization on slippery surfaces.
Across the upper edge of the board, above the function keys, is a rubberized slot. Meant to act as a display stand, it runs the width of the keyboard. It's designed to hold mobile devices as large as a 10-inch ( 258mm ) tablet. The stand cradles phones and tablets at a comfortable 50-degree angle, and it's wide enough to hold a tablet alongside a smartphone, if both are oriented in portrait mode.
This curvy keyboard displays well-spaced round keys, deep travel, and decent, but slightly mushy, response. The K480 is comfortable to type on, offering a pleasurable tactile feedback once you place your hands on it. The key arrangement is specifically designed for multiple operating systems, with "Alt" and "Cmd" keys for Windows and MacOS. For mobile devices, the top row of keys offers shortcuts for the Home and Back keys found on Android and iOS devices.
In this area, Logitech has some more work to do because the command keys don't fully work for some of the supported distributions. The K480 keyboard uses Bluetooth for establishing the connection between devices and it can pair up to three devices using the following operating system: Windows, Chrome-OS, Android, Mac OS and iOS. You can find the full set of specifications of the keyboard here: Bluetooth Multi-Device Keyboard K480.
Using The Logitech K480 Multi-Device Keyboard
Setting up the keyboard is pretty easy since we have all the instructions necessary displayed above the keys. Let's get started:
Step 1: Turning the board upside down, on the right from the batteries slot, you can find the turn On/Off switch. When you enable the keyboard a green light will appear near the switch.
Step 2: Enable the Bluetooth adapter on your device and find the keyboard on the list.
Step 3: Now we need to find the two buttons located on the right upper corner of the keyboard.
The next thing we need to know is that the left button is for Android, Windows, and ChromeOS users, and the right button is for iOS and MacOS. Select the button appropriate for your device and hold it for three seconds, time in which the blue light should start flickering.That indicates you should select to connect to the keyboard on your mobile device.
Step 4: Next a window will pop up that tells you to enter a combination on the keyboard and then press enter. After that the blinking light will turn solid blue, indicating that you are connected and ready to go.
Now let's talk about the feature that made The Logitech K480 keyboard famous: efficiently using multiple mobile devices in parallel.
On the upper left side of the keyboard, you can see a dial with three switching positions available. Each one of the dial's positions indicates a pair connection between the keyboard and a mobile device.If you have a paired device on the first channel, but you want to add another one, you just need to change the channel and repeat the steps we described before. When you switch from a device to another, you can instantly continue typing on the current device, which is why I think the Logitech team deserves congratulations on this feature.
Let's say you are traveling by train and you have the Logitech K480 keyboard and tablet set up to work on a project to pass the time. You hear a buzzer coming from your smartphone, where you see a text message from your best friend and you two start a conversation. Next thing you know, you are shifting from working on the tablet, to writing texts on the smartphone in its little keyboard, which is such an annoying loop to be trapped in. Well, we have a solution to that. You just switch the channel, connect the phone (unless it's a Windows Phone) and: Voila! You now can save time and nerves by switching between the two devices in seconds. I know! Cool right?
Verdict
The Logitech K480 Bluetooth Multi-Device Keyboard succeeds in its all-in-one approach. Using Bluetooth to establish a wireless connection, the keyboard is compatible with almost all operating systems and its innovative dial mechanism allows you to seamlessly switch between up to three devices. That is why the Logitech K480 is the perfect weapon for people who work in an office all day and/or have to travel for business and want the most efficient keyboard, that can shift in an instant between devices and offer a comfortable typing experience at a fair price.
