AULA F75 vs GravaStar Mercury K1: your questions
The GravaStar Mercury K1 has a significantly larger 8000mAh battery, which should provide much longer usage between charges compared to the AULA F75's 4000mAh battery. The vendor description for the K1 emphasizes its streamlined design for extended use.
Yes, according to the Epomaker vendor page, the AULA F75 has downloadable software. The listing specifies that the software supports Windows systems. It is used for customizing the RGB lighting and key functions.
Yes, both keyboards feature hot-swappable sockets. This allows you to easily change the mechanical switches without soldering. The GravaStar vendor page notes its sockets support both 3-pin and 5-pin switches.
The AULA F75 offers a silent switch type, which is specifically designed to reduce noise. Furthermore, its five-layer sound dampening system with foam and silicone pads is engineered to minimize typing noise. The GravaStar K1 uses linear switches which are also relatively quiet, but lacks the described multi-foam construction.
Rapid trigger is listed as an extra feature for the AULA F75. It is a gaming-oriented function that allows for faster keystroke resetting, which can be beneficial in fast-paced games. This feature is not mentioned in the specifications for the GravaStar Mercury K1.
The AULA F75 uses Cherry-profile double-shot PBT keycaps, as per its vendor description. PBT is known for its durability and resistance to shine. The keycap material for the GravaStar Mercury K1 is not specified in the provided information.
Based on the provided data, neither keyboard listing includes a wrist rest in the package contents. The AULA F75 comes with the keyboard, a 2.4G dongle, a Type-C cable, a keycap/switch puller, and a manual.
The GravaStar Mercury K1 uses a POM plate. The plate material sits between the switches and the PCB and influences the typing sound and feel. The AULA F75's plate material is not specified in the provided metadata.
Yes, both keyboards list 'Mac/Win Support' as an extra feature. This indicates they should be compatible with macOS and Windows operating systems. The specific key legends or function key mappings for Mac are not detailed.
The keyboards have very similar weights. The AULA F75 weighs 1023 grams, while the GravaStar Mercury K1 weighs 1080 grams. The difference of 57 grams is minor, and both are substantial, sturdy keyboards.
According to the GravaStar vendor description, the K1 features an 'unprecedented three-sided streamer effect' created by 'Aethereal catalysts.' This is a unique RGB lighting effect that transforms the look of the keyboard's aluminum exoskeleton, offering a distinct visual style.
The vendor description for the AULA F75 states it has 'finely-calibrated stabilizers' for a stable and hushed typing experience. It also mentions that the mechanical switches are factory-lubricated. However, it does not explicitly state that the stabilizers themselves are pre-lubricated.
