GravaStar Mercury K1 vs WOBKEY Rainy HE Pro: your questions
The WOBKEY Rainy HE Pro is designed for competitive gaming. It has a specified 8000Hz polling rate, Hall Effect magnetic switches with adjustable actuation points, and rapid trigger technology, which are features aimed at minimizing input latency and providing precise control.
Yes. The GravaStar Mercury K1 supports Bluetooth and 2.4 GHz wireless connectivity, allowing you to pair it with multiple devices like computers, tablets, or phones. It also has a wired USB-C mode.
The GravaStar Mercury K1 has an 8000mAh battery. While the exact runtime depends on usage and lighting, a battery of this capacity typically supports extended wireless use, potentially lasting for weeks with moderate use before needing a recharge.
The WOBKEY Rainy HE Pro comes with Gateron Jade Pro Magnetic switches. These are Hall Effect switches that use magnets instead of physical contacts, and they feature adjustable actuation points from 0.1mm to 3.3mm and configurable rapid trigger.
Yes, both the GravaStar Mercury K1 and the WOBKEY Rainy HE Pro have hot-swappable sockets. This allows you to change switches without soldering. The GravaStar listing mentions support for 3-pin and 5-pin switches.
No, not with any switch. The WOBKEY Rainy HE Pro uses Hall Effect technology and its product description states it is currently only compatible with specific magnetic switches, namely TTC KOM, TTC KOM RGB, and Gateron Jade Pro models.
The GravaStar Mercury K1 is listed at 1080 grams (1.08 kg). The weight for the WOBKEY Rainy HE Pro is not provided in the specifications, though it does include a patterned stainless steel external weight which adds to its mass.
The GravaStar Mercury K1 listing explicitly includes Mac support in its features. The WOBKEY Rainy HE Pro listing only confirms Windows compatibility, so its functionality with Mac may be limited or require further verification.
Both keyboards use aluminum for their cases. The GravaStar Mercury K1 has an aluminum alloy exoskeleton, and the WOBKEY Rainy HE Pro features a CNC anodized aluminum case.
The WOBKEY Rainy HE Pro comes with double-shot keycaps made from a combination of PBT and PC (polycarbonate) materials. Double-shot construction means the legends are durable and won't wear off.
Rapid trigger is a feature of the WOBKEY's Hall Effect switches that allows for faster repeated keystrokes. It lets you reset and re-actuate a key without releasing it fully, and it is adjustable from 0.01mm to 1mm on this keyboard.
