Keychron K5 V2 vs Yunzii AL98Low-Profile vs Full-Size Aluminum

The Yunzii AL98 has a significantly larger 8000mAh battery compared to the Keychron K5's 2000mAh battery. Based on the specifications alone, the AL98 will last much longer between charges, making it better for extended wireless use.

No, according to Keychron's product description, the K5 QMK V2 is only compatible with specific low-profile mechanical switches. The vendor page states it works with Keychron Milk POM switches or Gateron/Keychron low-profile switches, and not with standard profile or low-profile optical switches.

The Yunzii AL98 uses a gasket mount, where the plate holding the switches is suspended on rubber gaskets to absorb vibration and create a softer typing feel. The Keychron K5 uses a PCB mount style, which typically involves the switches being mounted directly to the printed circuit board, often resulting in a firmer typing experience.

The Keychron K5 is more travel-friendly. The manufacturer describes it as an 'ultra-slim' low-profile keyboard, and it has a smaller battery likely contributing to lower weight. The Yunzii AL98 is very heavy at 2175g and has a larger footprint, making it less ideal for frequent transport.

Yes, both the Keychron K5 QMK V2 and the Yunzii AL98 list Mac and Windows support in their specifications. The Keychron vendor description also notes it includes keycaps for both operating systems and can be configured with different keymaps for each.

The Keychron K5 uses low-profile keycaps to match its switch design. The Yunzii AL98 uses Cherry-profile PBT double-shot keycaps, which is a common profile for standard-height mechanical keyboards.

This is subjective, but the Yunzii AL98 has structural advantages for a premium feel. Its gasket mount, screw-in stabilizers, and sound-dampening design aim for a smoother, more muted typing experience. The Keychron K5 uses various acoustic foams and redesigned stabilizers to refine its low-profile sound and feel.

Yes, both keyboards support QMK and VIA, which are open-source firmware and configurators that allow for extensive key remapping, macro creation, and lighting control without proprietary software. The Keychron K5 also offers the Keychron Launcher web app for configuration.

Yes, the connectivity specifications for the Yunzii AL98 include 2.4 GHz wireless alongside Bluetooth and wired USB-C. The Keychron K5 QMK V2 offers Bluetooth and wired connectivity, but 2.4 GHz is not listed in its specs.

The Yunzii AL98 vendor description states its linear switches are factory-lubed. The Keychron K5 vendor description states its Milk POM switches are pre-lubed. Therefore, both keyboards are advertised to have pre-lubed switches from the factory.

The Keychron K5 vendor page specifies its RGB version offers 22+ dynamic backlight settings. The Yunzii AL98 description mentions 16.8 million color options and dynamic lighting effects but does not specify a number of preset modes. Both allow for deep customization via QMK/VIA.
