Yunzii C75 vs YZ19: your questions
No, the YZ19 is not a full keyboard. It is a numeric keypad, or numpad, with 19 keys and one knob. It is designed as an accessory to complement a separate primary keyboard that lacks a number pad.
The Yunzii C75 has a significantly larger 5500mAh battery compared to the YZ19's 1500mAh battery. Based on the listed capacities, the C75 should offer longer use between charges for wireless operation.
Yes, both keyboards feature hot-swappable PCBs. The C75 vendor description states it supports both 3-pin and 5-pin mechanical switches. The YZ19 vendor description also confirms it is a full-key hot-swappable keyboard that allows for freely changing switches with 3-pin/5-pin.
Yes, according to the metadata, both the Yunzii C75 and YZ19 list Mac support as an extra feature. Their vendor descriptions also mention compatibility with macOS, among other systems.
The Yunzii YZ19 is far smaller, measuring 136 x 92 mm. However, it is only a numpad. For a complete keyboard in a small footprint, the C75's 75% layout (336 x 162 mm) saves space compared to a full-size board while providing all essential keys.
The provided specifications and vendor description for the Yunzii C75 do not mention a knob. The Yunzii YZ19, however, includes knob support and features a programmable knob according to its product page.
Both use a gasket mount structure, which the manufacturer states provides a softer typing feel. The primary structural difference is the case material; the C75 uses an aluminum case, while the case material for the YZ19 is not specified in the provided metadata.
Yes. Both use PBT keycaps, but with different profiles. The C75 uses dye-sublimation PBT MOA profile keycaps. The YZ19 uses dye-sublimation PBT keycaps with an XDA profile, which typically have a lower, uniform shape.
The YZ19 can be used for gaming as a macro pad for assigning complex shortcuts or commands. However, it cannot function as a primary gaming keyboard because it lacks alphanumeric and movement keys. For primary gaming input, the C75 is the necessary choice.
Both offer programmability. The C75 vendor description mentions programmable software for remapping keys and creating macros for Windows and Mac. The YZ19 vendor description states it has a driver to program the pad for custom shortcut functions and supports NKRO for all 19 keys.
Yes, according to the metadata, both the Yunzii C75 and YZ19 feature south-facing RGB LEDs. South-facing LEDs are often preferred for compatibility with Cherry-profile keycaps to avoid interference.
