What will you mostly use it for?
The AL80 takes five of six categories on the strength of QMK/VIA, the LCD screen and a larger battery. The C75 only leads for travel, where its lower 1008g weight matters more than firmware features. Gaming is close because both list a 1000 Hz polling rate, but the AL80's battery and remapping tip it. Office, programming, modding and content creation all favor the AL80's customization and on-board display.
Pick the Yunzii AL80
- 1000 Hz polling rate is listed for both, so latency is comparable on paper.
- The AL80's 6000mAh battery supports longer wireless sessions than the C75's 5500mAh.
- QMK/VIA support on the AL80 allows per-key remapping and macro programming for game-specific layouts.

Yunzii AL80 vs C75: your questions
Yes, the AL80 is listed with QMK and VIA support, enabling full key remapping, macro programming and RGB control. The C75 does not list QMK or VIA, so its customization depends on vendor software and online website tools.
The AL80 weighs 1438.5g, while the C75 weighs 1008g. The C75's lower weight makes it easier to move or pack, while the AL80's heavier aluminum body stays put on a desk.
Yes, both the AL80 and C75 are full hot-swappable and support 3-pin and 5-pin mechanical switches. That means you can change switches without soldering on either board.
The AL80 has a 6000mAh battery, compared with the C75's 5500mAh. Both support Bluetooth, 2.4 GHz and wired USB-C connectivity for flexible use.
No, the C75 does not list an LCD screen, while the AL80 features a customizable LCD that can show time, GIFs, photos, battery status and connection mode. If on-board information or animated displays matter, the AL80 is the relevant choice.
The AL80 uses double-shot PBT Cherry profile keycaps, while the C75 uses dye-sublimation PBT MOA profile keycaps. Both are PBT, but the profile and manufacturing method differ.
The C75 is the better travel candidate because it weighs 1008g versus the AL80's 1438.5g. Both offer tri-mode connectivity, so you can use Bluetooth or 2.4 GHz without a cable.
The AL80 lists knob support and a metal mechanical knob as part of its 75% layout with LCD screen and back weight. The C75 does not list a knob.
Yes, both the AL80 and C75 list Mac and Windows support. The AL80 adds QMK/VIA, which can be useful for remapping across systems.
The AL80 is offered with YUNZII Cocoa Cream V2 Linear or Gateron Zero Linear switches, both pre-lubed linear options. The C75 is offered with YUNZII Milk V2 Linear or YUNZII Candy Linear switches, and its hot-swap socket also supports tactile or clicky switches.
The AL80 is the stronger programming pick because QMK/VIA support enables full key remapping and macro programming. The C75 relies on vendor software, which limits firmware-level customization.
The C75 comes in Pink, Beige, Blue, Purple and Choco color choices. Its cake-themed design and dye-sublimation PBT MOA keycaps distinguish it visually from the AL80's Silver, Black and Beige options.
