Customer Questions & Answers
-

Can I use the Keychron K4 with my smartphone, laptop, or iPad?
Answer: Yes, the Keychron K4 version 2 can connect with up to 3 devices via Bluetooth and switch among them easily. -
Question:
How long can the battery last?
Answer: The K4 can last up to 240 hours with backlit disabled and has a big 4000 mAh battery that is one of the biggest in mechanical keyboards. -
Question:
What type of switch does the Keychron K4 have?
Answer: The Keychron K4 has the pre-installed Gateron G Pro mechanical Blue switch providing unrivaled clicky responsiveness with up to 50 million keystroke lifespan. -
Question:
What kind of keycaps do I need to get to replace the ones that came with mine? What do I search for?
Answer: 96% keycap set. The modifiers you need that aren’t regular is a 1.75u shift, 1u Alt, 1u FN, 1u ctrl and 1u number 0 -
Question:
This is rechargeable?
Answer: Yes it is. 4000mAh battery. USB C port for charging. Press fn-B to see a color-indicated battery status. Been using mine for 2 weeks, rgb for hours a day - still green! Green = battery level over 70 %. Blue = battery level over 40 %. Red = battery level under 39% or lower. -
Question:
Does it use standard key caps? I’ve got a universal set to convert gaming keyboards to Spanish layout, would it fit?
Answer: Most of them are standard. Keep in mind the space-row has some unusual widths, r-shift is definitely a weirdo too (unusually short). -
Question:
Can the RGB backlight be set to white only?
Answer: Yes it can. Scroll through the selections then stop when all of the keys illuminate white. Then stop, they will stay white.
Keychron Keyboards Keychron K4J3 Editorial Review
The Keychron K4 is a mechanical keyboard with a 96% keycap set that uses 5-pin switches, except for the tilde key which is a little different. It has a 4000mAh battery and USB C port for charging, supporting up to 40 hours of battery life. The RGB backlight colour can be set to white or picked from several options. Keycaps used are mostly standard with some exceptions like a short right shift key. Customers are generally happy with the product, praising its form factor, Bluetooth and compatibility with both Windows and Mac. The only complaints are the uncustomizable RGB lights and poor sleep mode implementation.
