FAQ

Redragon UCAL K673 vs UCAL MAX K673: your questions

The primary difference is switch customization. The UCAL MAX K673 features hot-swappable sockets and comes with PBT keycaps, while the standard UCAL K673 has a soldered PCB and is offered in a German QWERTZ layout. Both share a 75% form factor, gasket mount, and tri-mode wireless.

The vendor description for the Redragon UCAL K673 does not specify the keycap material. In contrast, the UCAL MAX K673 explicitly lists 'OEM Profile PBT Keycaps' as a feature, suggesting the standard model likely uses a different, unspecified material.

Yes. According to Redragon, the UCAL MAX K673 has an 'UPGRADED HOT-SWAP' socket that is compatible with nearly all 3-pin and 5-pin mechanical switches. This allows you to change switches without soldering.

Both keyboards are designed for quiet typing. The UCAL K673 uses 3.5mm PO foam and a silicone pad, while the MAX lists '5 Sound Absorbing Pads'. With similar gasket mounts, their acoustic performance is likely comparable. The choice may come down to your preferred layout.

Yes, both the UCAL K673 and UCAL MAX K673 feature a dedicated 'ONE-Knob' control. According to the manufacturer, this knob provides easy access for adjusting backlight brightness, volume, and media playback.

The Redragon UCAL MAX K673 comes pre-installed with Linear Mint Mambo switches. The vendor description notes these are custom linear switches designed for an enhanced typing experience.

Both the Redragon UCAL K673 and UCAL MAX K673 are equipped with a 4000mAh battery. The manufacturer states this provides long-lasting use for intensive gaming and work applications, though actual battery life will depend on usage patterns and RGB settings.

The UCAL MAX K673 package includes the keyboard, a detachable USB Type-C cable, a keycap and switch puller, a 2.4 GHz nano receiver, four spare switches, a user manual, and a Redragon sticker.

They are equally portable. Both keyboards share a 75% compact layout, tri-mode wireless connectivity, and very similar weights (1240g for the K673 vs 1200g for the MAX). The choice for travel would depend on whether you need the German layout or prefer the MAX's included accessories.
