In the past six months alone, Logitech has introduced new mechanical keyboards, new headphones, new mouse products and HD web cameras for webcasts. However, these products are mainly for gamers. In the broader consumer market, Logitech has been developing products that are not only for PCs, but for multiple devices.

Meet Logitech K780

Like many other similar products on the market, the Logitech K780 multi-device (hereafter referred to as “K780”) can connect to any number of Bluetooth devices, but its goal is to make the process of working on multiple devices as seamless and smooth as possible.

This $80 keyboard fits Windows, Mac, Android, iOS and Chrome OS devices. Logitech launched the Logitech K780 in the EMEA (Europe, Middle East and Africa) market in June.

The K780 is an upgraded product of Logitech's K380 keyboard launched last year, but there are many differences between the two products. First of all, the K780 has a bracket for placing tablets and mobile phones. Logitech's philosophy is that when working on a PC, if you need to quickly enter a message on a mobile device, users do not have to “finger” to complete this task with their fingers on the phone or tablet.

VentureBeat said that in addition to the brackets, the K780 is a full-featured desktop keyboard compared to the K380, which is a lightweight, portable keyboard that is easy to carry around. The numeric keypad on the right side of the K780 implies that it is primarily a desktop keyboard and supporting multiple devices is just an added benefit.

The mobile device bay is certainly good, but in-depth understanding of the inner workings of the K780 is really interesting. Of course, any Bluetooth keyboard can support multiple devices, but switching between multiple devices is undoubtedly a painful process. This is the advantage of the K780. The user can press one of the 3 buttons to switch the device.

In the upper left corner of the keyboard, behind the ESC key, the user sees three large white buttons labeled 1, 2 and 3 (they can also be used as F1, F2, and F3 buttons). To connect a device to one of the buttons, the user needs to hold down the button for 3 seconds until the button starts flashing and the device is connected to the keyboard via Bluetooth.

In the configuration of VentureBeat writer Paul Sawers, button 1 is connected to the notebook, button 2 is connected to the iPad, and button 3 is connected to the iPhone. To Sols's regret, his Android phone does not support Bluetooth LE. It cannot be linked to the K780. However, most flagship Android phones (and iPhones) support Bluetooth LE, so this will not be a problem for most potential buyers.

Assuming that the configuration is similar to the following figure, the user can press button 1 to enter text on the computer; press button 2 to reply to the email on the iPad; then press button 3 to reply to the WhatsApp message.

After two days of using the K780, Sowers discovered two minor problems with it - although they were not enough to influence the user's buying decision. First, there is no indicator on the keyboard that the Caps Lock or Num Lock button is active. He thinks such an indicator is still necessary, especially when entering the password. VentureBeat consulted Art O Gnimh, Logitech's keyboard business head, on this issue. The answer was that this was purely a design decision. There were indicators on the three switch buttons on the keyboard, and a power supply. / Battery life indicator. In short, Logitech does not want to add too many lights on the keyboard.

It is worth pointing out that Logitech provides user-downloadable Options software that can display reminders on the screen, including information for activating Caps Lock and Num Lock. The software also allows users to customize keyboard keys, including shortcut keys.

In addition, users cannot easily know which shortcuts the keyboard can provide. For example, the K780 does not have a dedicated screen print button and the user cannot know how to take screenshots on the PC. It turns out that the user can complete this task by pressing "FN + Del", but how can the user know?

Users can view a PDF document on the Internet. The document shows that the K780 provides enhanced features such as shortcut keys, hotkeys, and media keys.

If you can tolerate these two minor issues, the K780 is a near-perfect multipurpose keyboard.

VentureBeat stated that the K780 has some interesting features worth pointing out. Many of the K780 key combinations available on PCs are also suitable for mobile devices. For example, "Alt + Tab" for switching applications on Windows is also suitable for switching applications on the iPad; likewise, "FN + Del" is available on all devices. Screen captures can be performed on the screen. "FN + ESC" can perform lock screen on all devices. All this is seamless, and the user does not need to change the settings to adapt the equipment used.

Ognim said, "We can quickly and comfortably create documents on the computer, but replying to text messages on mobile phones also requires two fingers. With the K780, users can be as comfortable as desktops on all devices. Enter text and switch seamlessly between devices with just one button press.”

All in all, entering text on the K780 is comfortable and Sols is happy to recommend it to users. However, users who wish to buy a lighter weight portable keyboard should consider other products - the weight of 875 grams is not really light. Given its relatively slim figure, the weight of the K780 made Sors a little bit surprised. On the positive side, this gives it a feeling of solidity and makes Sowers believe it will not be damaged in the short term.

There are battery problems. The K780 requires two AAA batteries, and Logitech expects its battery life to reach about two years. If its life time can really reach 2 years, this will surprise the user, even if the battery life is only 1 year, the user will be quite satisfied.
