AULA S75 Pro vs GravaStar Mercury K1: your questions
The AULA S75 Pro has a specified 4000 Hz polling rate. The GravaStar Mercury K1's product listing does not specify a polling rate, so a direct comparison cannot be made from the provided information.
No. The AULA S75 Pro features a 1.14-inch LCD screen, according to its vendor description. The GravaStar Mercury K1 does not have a screen.
Based on battery capacity, the GravaStar Mercury K1 has a larger 8000mAh battery compared to the AULA S75 Pro's 4000mAh battery. This suggests the GravaStar will likely last longer between charges, though actual runtime depends on usage patterns like RGB lighting and wireless mode.
Yes. Both the AULA S75 Pro and the GravaStar Mercury K1 are listed as hot-swappable. The AULA's vendor page specifies compatibility with both 3-pin and 5-pin switches.
The GravaStar Mercury K1 features an aluminum alloy exoskeleton case, which the manufacturer describes as combining strength and lightness. The AULA S75 Pro's case material is not specified as aluminum in the provided data.
The AULA S75 Pro is likely better suited for noise reduction. Its vendor description details an extended silicone pad, single-key PCB slotting, and five layers of sound-dampening foam specifically designed to reduce hollow sounds. The GravaStar listing mentions a flexible plate to reduce noise but does not detail internal dampening materials.
Only the AULA S75 Pro includes a multifunction knob, which can be used for volume control and other adjustments. The GravaStar Mercury K1 does not have a knob.
According to the vendor page, the AULA S75 Pro offers a choice between AULA Caramel Latte linear switches and AULA Star Arrow linear switches, with their specific actuation and travel distances listed.
The AULA S75 Pro vendor description explicitly states support for Windows, Mac, iOS, Android, PlayStation, and Xbox. The GravaStar Mercury K1 listing confirms Mac/Win support but does not mention console compatibility.
The GravaStar Mercury K1 is slightly heavier, weighing 1080g compared to the AULA S75 Pro's 1000g. This is likely due to its aluminum construction.
The AULA S75 Pro package includes the keyboard, a Type-C cable, a 2.4G receiver, a keycap puller, and a user manual, as listed on the vendor page.
