An ode to the Keychron K3 (V2)
Settle in
Normally we use this piece of text to write something fun and light-hearted about a product. But now I want to use it to make sure you settle in with a cup of coffee or tea before you start reading, because there is quite a lot to tell about the K3. Are you seated? Perhaps a biscuit to go with it? Let's go!
Why the Keychron K3 keyboard?
Highly featured
The Keychron K3 gives you all the keys and functions you need in a compact size. This means that a numeric keypad is absent, for ergonomic reasons, but it does have hotkeys that can be used by pressing combination keys. Besides the compact size, the keys are flat, which is unique for a mechanical keyboard.
The K3's connectivity is fantastic. Via Bluetooth, you can wirelessly connect up to three devices to the keyboard at the same time. Using the toggle switch, you can switch between your connected devices in a flash. For example, one moment you might be working on your laptop, and the next you're quickly typing a WhatsApp message about dinner. A fourth device can be connected with a cable (USB). Of course, connecting a single device and using the USB cable for that is also an option.
Matching K3 walnut wood wrist rest
The wrist rest, made from American walnut wood, perfectly complements your K3 keyboard. The high-quality wood is smooth and features 4 anti-slip points on the underside to ensure the wrist rest stays in place. Thanks to the support, your wrists and hands are at the correct height for using the keyboard. This optimises relaxation and helps prevent injuries. You can add the wrist rest to your order at the top right of the page.
PLEASE NOTE: Keychron wrist rests are natural products and therefore never identical. The product you receive may differ from the photo.
Travel pouch
The Keychron travel pouch is the optimal way to carry your Keychron K3 keyboard. The pouch is made of Saffiano leather, which provides a combination of style, durability and flexibility. The pouch is available in three colours. You can find more information about the travel pouch here. You can add it to your order in the desired colour at the top right of the page.
What makes an ergonomic keyboard so good?
Anyone who does a lot of computer work knows that this can be strenuous for your wrists, shoulders, back and neck. A good keyboard can help you with this. The Keychron K3, for example, has a compact design. The keys are also extra easy to press. You can also place your mouse close to the keyboard. All of this is to minimise muscle strain, which can help prevent or reduce injuries.
Get the most out of this product
Choose your switches
Here you choose not only the keyboard but also the type of switches it is equipped with. You can choose between Red and Brown Keychron Optical low profile mechanical switches. Here you will find an overview of the Keychron switches so you can choose the right ones for you.
Hot-Swappable
Do you prefer to customise the board completely? You can! Because the Keychron Optical switches are "Hot-Swappable". This means you can remove and replace the switches very easily. Only Keychron low-profile optical switches fit this keyboard.
The K3 can be updated, so any production and/or design flaws can be fixed. The firmware will be available soon. So check this Keychron page regularly to see whether updates are available.
Don't miss this either
The Keychron K3 features a 1550mAh battery that lasts up to 34 hours with normal use. The keyboard also has backlighting, making the keys clearly visible in dimly lit spaces.
Here you have the choice between standard white and RGB. The latter gives you access to 18 different colour effects with four brightness levels. The Keychron K3 is suitable for both Windows & Mac. With a slider switch at the top, you can easily switch between operating systems. System-related keycaps are included and you can easily swap them yourself.
The difference with the K3 V1
Keychron has not implemented major changes in the V2. For example, they have added feet that allow you to raise the back of the keyboard.
