## Description

desertcart.com: Keychron K4 Wireless Bluetooth/USB Wired Gaming Mechanical Keyboard, Compact 100 Keys RGB LED Backlit Gateron Brown Switch N-Key Rollover, Aluminum Frame for Mac Windows, Version 2 : Video Games

Review: Solid keyboard with great illumination and key response and feel - Amazing keyboard. I'm like my keys tactile and clicky and this device checks both boxes! The size is very compact and does sacrifice a couple of keys. It's impressive that I still have a number pad. I've not used the wireless feature and only connect via the included USB-C cable. The illumination options are impressive as are the onboard media control keys initiated by holding down the FN key, then pressing the corresponding function key. It has a good weight meaning it doesn't slide a round when I'm typing or moving the keyboard tray.
Review: Best mechanical keyboard I own - I’m a mechanical keyboard enthusiast, and have several, but was often recommended to grab a Keychron to add to my collection. I am currently using this model, the K4 Bluetooth with blue Gateron switches and RGB backlighting, to write this review on my phone. Of all the keyboards I own, this is my new favorite and the one I now use the most. I have owned a Dierya 60% Bluetooth (my least favorite, ? key in a weird placement), got a Royal Kludge full-size 104-key Bluetooth with white backlight (good, just bulky), and have a Royal Kludge 60% that has been my go-to for a simple portable writing keyboard. Once I got this Keychron, it pretty much replaced my RK 60% for both personal use and for work. As I typed this, the battery died, but that’s only because I use it constantly, and like to turn on the RGB backlighting for a little razzle dazzle when I’m sitting to write enjoyable. Only takes a few minutes to recharge, not long for a full recharge. It could last a week or more of constant use, without the backlighting, and several days with RGB backlighting. You can also charge it with the cable on a laptop while using it via Bluetooth on another device, which is nice. The aluminum frame is awesome, I’ve accidentally dropped it a couple of times, got the slightest scratch, and still works like a champ. It’s the keyboard equivalent of one of those old Nextel yellow brick phones, ha. Lightweight enough to throw into a backpack, quick Bluetooth connection, easy to set up and use, and definitely worth the money. I got it used, like new here on desertcart, was probably a return, and I’ve had zero problems with it. Even at full price, a worthwhile investment. The full number pad is what I wanted for my desktop trading and for inputting grades at my teaching gig. By far the best recommendation I got, and I definitely recommend it to other mechanical keyboard enthusiasts. Comes with a very professional-looking layout, but easy to customize if you dig fun color keycaps. If you spend a little extra to get the fully hot-swappable one, the switches are also easy to replace so the keyboard lasts for a long time. I’m super happy with my investment, and now use this keyboard on the daily for work and personal use.

## Questions & Answers

**Q: Why usb c to usb a? the cable provided has usb c connector at the keyboard end and usb a at the computer end. why not usb c at both ends?**
A: Probably because the rest of the computer industry hasn’t moved completely to usb c. USB A is a highly robust connector going on 24 or so years. The USB C connector though fast has been known to lose how well it holds into the receptacle after awhile. USB A is also still the most common connector thus making it the most compatible.

**Q: How can i program the backlights to display my own rgb sequence?**
A: Unfortunately with the Keychron K4 you are unable to program your own colors or pattern.  You can select from some preset patterns or a specific color using a key on the keyboard.

**Q: "usb accessories disabled" when connecting through an external display. any idea as to how to fix this ?**
A: What's giving you that message?  Windows or the display itself?  Doesn't sound like windows... If so, Google the message with the model of your display.  Probably many other people have had this problem.

**Q: Are the switches hot swappable?**
A: No, on this keyboard you can’t hot swap.  It’s a good keyboard but it’s not what your looking for if you want to change out keys.

### ⭐⭐⭐⭐⭐ Great, but I prefer 100% sizing.
*by G***Y on November 5, 2025*

Five stars for quality but not for me. This keyboard is fantastic. I like the build, the buttons are extremely clicky, and Everything seems super responsive and awesome. I did have to disable sleep mode and had some initial issues with setup, but after I got those resolved, I can't say enough good things about this keyboard. The only thing is this keyboard is not for me. I didn't realize that this was like a 75% keyboard, so I'm returning it and purchasing the 100% keyboard immediately. This brand seems awesome and I saved a ton of money getting the open box version of this item which came in perfect condition. It just didn't have the USBC cable, which I really didn't need. My recommendation is to get it, but also if you're used to a normal size keyboard then don't get this. Get the 100% keyboard version. This is my first mechanical keyboard ever, and I usually don't leave reviews so just let that sink in lol.
