Varmilo VPT108 Chang'e

The Varmilo VPT108 Chang'e is a full-size mechanical keyboard designed for users who want flexible connectivity and easy switch customization. It suits typists and general users who value a traditional layout with modern wireless options and the ability to swap switches without soldering. Its features support both wired and wireless use, making it adaptable for different environments.

Key Features

• Hotswap PCB allows changing switches without soldering, enabling easy customization or repair.
• Three connection modes: wired USB-C, Bluetooth 5.1, and 2.4 GHz wireless, offering versatility for desktop and mobile use.
• RGB backlighting provides adjustable lighting effects, useful for low-light conditions or visual preference.
• 3-way cord channel lets users route the cable from left, right, or center, improving desk organization.
• Preset multimedia key combinations add quick access to common functions without dedicated keys.

Build Quality

• Aluminum top plate adds rigidity and a solid feel during typing.
• Double-layer silicone sound absorption reduces typing noise, enhancing acoustic comfort.
• Thick dye-sublimated PBT keycaps resist wear and provide a textured, durable surface.
• ABS materials on top and bottom balance weight and cost without compromising stability.
• Two-step adjustable kickstand allows users to change typing angle for ergonomics.

Typing Experience

• South-facing MX-compatible switch stems support a wide range of Cherry MX-style switches.
• Available with several Cherry MX switch options, including tactile, linear, and silent variants, catering to different typing preferences.
• Sound absorption and PBT keycaps contribute to a quieter, more controlled typing sound.

Connectivity

• Wired mode offers a 1000 Hz polling rate for minimal input delay, suitable for responsive typing or gaming.
• Bluetooth connection has a lower polling rate (133 Hz), better for casual use or mobile devices.
• 2.4 GHz wireless mode balances latency and convenience with a 250 Hz polling rate.

Trade-offs

• Polling rates vary significantly by connection type, which may affect responsiveness depending on use case.
• Bluetooth latency and polling rate are lower, making it less ideal for fast-paced gaming.
• Preset multimedia keys require key combinations rather than dedicated buttons, which may slow access.
