Corsair K63 and K63 Wireless Gaming Lapboard review: PC-gaming on your lap

Wireless gaming with mechanical switches


Battery life, wireless connection and typing

We often discuss wireless keyboards, but mechanical models are usually connected with a cable. Apart from Logitech, from which we recently discussed the wireless G613, mostly smaller manufacturers have released a wireless mechanical keyboard. Corsair is, for the time being, one of the few well-known brands that dares to sell a wireless model.

The K63 Wireless is a completely different keyboard from the G613, not in the least because of the smaller size due to the lack of a numpad. The Corsair keyboard differs from the G613 In other respects as well. Logitech has equipped its model, in terms of features, fairly frugally, and it almost seems like you could type away on two batteries for a year and a half. The K63 Wireless is equipped much more abundantly. For example, it has background lighting.

Whereas the Logitech G613 is powered by separate batteries, Corsair has chosen a built-in battery for the K63 Wireless. There is no official way to replace it; we find this less satisfactory. Although the battery should last 'hundreds of charging cycles' according to Corsair, the expected service life of a battery is simply shorter than that of the rest of a device.

We have tried to open the keyboard, so that we could see if there was still a possibility of getting to the battery. With a bank card and a little patience, we managed to pry off the top part of the casing from the bottom part, after which the battery, among other things, became visible. This battery is a a 18650 battery with a capacity of 2950 mAh. After a little bit of searching, you can order a battery like that for a few euros online, although you need to make sure that the battery that Corsair assembles includes a specific cable to connect it to the circuit board. Most of the batteries we found online don't have that, and soldering a cable to a battery yourself can be dangerous if you don't know what you are doing. All in all, it would have been more convenient if Corsair had installed an easily replaceable battery.

This is all the more true because the battery life of the K63 Wireless is quite short. If you leave the LEDs on the keyboard fully lit, the battery pack will be flat after 15 hours, according to the manufacturer's specifications. With the LEDs on medium settings, the operating time increases to 25 hours, if the lights are switched off you can type up to 75 hours without a cable.

Wireless with a wide reach

The K63 Wireless can connect to your PC in three ways. In addition to the wired connection via usb, you can use the included dongle, which with its length of 2 cm is a bit larger than the well-known Logitech Nano Receiver, but it makes a similar wireless connection via the 2.4 GHz band. Incidentally, that's the same band on which Bluetooth works, but according to Corsair the dongle is supposed to be optimized for an extra low input of '1 ms'. In principle, the connection between the keyboard and the dongle is automatic. If not, a pairing button is hidden somewhere in the CUE application.

The reach of the connection is excellent, according to our measurements. The signal first starts to lose strength after 20 metres.

The K63 Wireless can also connect via Bluetooth, allowing you to use it with Android devices. The keys 'F1' up to and including 'F4' can be used in combination with the 'FN' button to control the Android system buttons. Provided your computer is equipped with Bluetooth, the K63 Wireless also works with a PC in that way, but then the device does not appear in the CUE software.

To prevent eavesdropping, the wireless connection is equipped with 128-bit AES encryption. You can deactivate the protection by pressing the switch to turn off the Windows key, which should result in less delay.

Something to take into account: if you also want to use a wireless mice, you need a second receiver when you go for the new Corsair DarkCore SE wireless mouse. Corsair does not have, like Logitech, a 'unifying' receiver for multiple devices. So you will have to use two USB ports (just like in the case of wired connections, by the way).

Typing mechanically on red switches

Corsair uses the well-known Cherry MX switches in its mechanical gaming keyboards. On many other models of the manufacturer you can choose which type of mechanical switches you want, but on the K63 Wireless, only the red switches are available. This type of switch is generally considered suitable for gaming due to the light and linear scale. The tapping feel of the K63 Wireless is similar to that of other Corsair keyboards equipped with Cherry MX Red switches.
