Keychron K2 Review : A must for mechanical keyboard lovers.

Are you considering swapping your standard keyboard for something more exciting? If the answer yes, then the Keychron K2 Wireless Keyboard has to be up there as one of the top replacements.

The expectations surrounding the Kerchron keyboard series were high, but boy did they knock it out the park with this one. If you’re a fan of the mechanical click sound, reminding you of those old-school windows 97 keyboards, then read on below to understand this keyboard more.

The Build

As soon as you unbox the K2, the first thing you notice is the sleek, matte colour scheme, with a smooth finish to touch. Included within the box is a keycap puller, additional orange keycaps to pair with the ESC key & a cheat sheet for what each key means (mac & Windows).

This mechanical keyboard build is compact yet powerful, with Keychron retaining all the essential function keys without compromising on quality. The K2 keyboard itself features curved keycaps and Gateron key switches giving you super tactile feel compared to other mechanical keyboards out there.

The main feature, the one thing that enhances this good looking keyboard further, is of course, the RGB backlighting options. In total, the Keychron K2 includes 15+ types of different RGB colours backlights, each one more mesmerising than the other.

The chassis provides a solid feeling throughout this minimal, compact keyboard. It also offers more personalisation for a more comfortable typing experience with rubber feet, allowing you to adjust with a 6-degree angle.

With the options to use the keyboard wire/wireless, you’ll find the swatches for these options on the side. The first (after the USB port) is to switch the keyboard into Mac or Windows, whilst the second swatch is to switch between wired – off – wireless.

The base of the keyboard has two kick stand options which allows you to type at a 9 degrees incline if you needed to power through that long list of client emails.

Typing & Swatches

From the get go, you feel where you’re $89 have gone too. The feel of typing on the K2 is unbelievable (if you’re used to the traditional Mac/Windows keyboards). Keychron boast that the K2 allows you to type a lot faster than ordinary keyboards, and it definitely lives up to that statement. Your fingers seem to glide over the keys like they weren’t even there. The tactile response is to be admired, and with the customisation of switches beneath the caps, you can really start to tailor you typing experience.

One thing I could pick out is that If you’re coming from the traditional Mac/Windows keys (like me) then you may take longer to adapt to the compact layout of the keys, but you’ll find your rhythm soon enough.

The K2 switch travel distance measures in at 4+0.4mm, a big increase compared to earlier releases. This keyboard comes with a variety of swatches, notable the Gateron Red, Blue or brown switches. The keychron community recommends users who have never used a mechanical keyboard before to opt for the Brown switches, as they give you a smoother, tactile feel. If you’re into gaming and consider yourself mechanical keyboard master, then the blue switches offer a more fast, clicky tactile response.

Of course, it’s all down to your own opinion, whether you’re a regular mechanical keyboard user or not. The great thing about the Keychron K2 is that you can experiment with the different switches available and find the best one for you.

The Battery Life on the Keychron k2

Hands down the biggest fear when buying wireless products is the battery life. Is the device going to cut out after a mere couple hours of use, or is it going to last longer than the old Nokia 3310’s. Well, after using this kerchron K2 for a month now, I can say that the battery life lives up to the hype.

The K2 features a 4000mAh Rechargeable li-polymer battery, which packs a punch! Like me, the first thing you’ll do is connect the keyboard up to your computer and instantly start playing around with the backlight colours. I mean, if you don’t then whats wrong with you…?

If you are one of the people who have the backlight on 9 times out of 10, then Keychron has broken down the estimate battery life between charges:

  • BT Working Time (Backlit off): Up to 240 hours (Lab test result may vary by actual use)
  • BT Working Time (Single LED): Up to 68 hours (Lab test result may vary by actual use)
  • BT Working Time (RGB): Up to 72 hours (Lab test result may vary by actual use)

Another key element to the K2 is that if you find yourself away from the desk for a period of time, then the keyboard itself will enter sleep mode after 10mins, saving you even more battery time.

This can present issues though, as I’ve found myself on a client call for slightly over 10 minutes and the keyboard has gone to sleep. On top of that it does take a few seconds for it to turn back on and can become quite frustrating.

But, like always, theres a solution! A simple key combo (found in your K2 box) will disable sleep mode, allowing you to use and charge whenever needed.

To check the battery life on your keyboard, you can quickly press and hold both the fn + B keys. Green light means it is over 70%, Blue light means it is between 30-70% and when the battery life is under 30%, the lights will be flashing, indicating that it’s probably time to plug the charge lead in.

To reach fully charged level, the Keychron k2 will need a total of 3 hours, and you can still use this whilst it’s plugged into to your computer, added bonus!


The connectivity on the K2 is powerful. It allows you to connect via bluetooth to Mac/Ipad Pro or even Windows/Andriod devices (by toggling the switch on the left hand side of the keyboard).

I’ve tested this on my Macbook Pro 2019, My iMac 2019 & the Ipad pro 2020 and found it flawless throughout. Connectivity is quick, response time is even quicker and the price tag is looking like an absolute steel right now.

The Conclusion

The Keychron K2 Wireless Keyboard may not be the best ever out there, but it has definitely won my vote and I don’t think I’ll be switching to another mechanical keyboard anytime soon…🤙

The Keychron K2 is available direct from their website, with UK shipping time approx 2-3weeks.
