K1 SE, from Keychron's store
The K1 SE is the budget-tier low-profile TKL: ABS keycaps, a 190-hour battery rating, optical or mechanical switch options and about 550 g. The maker lists no QMK support on this version.
Our take, based on research
The no-frills K1. The long battery rating is the main draw.
Overview
The K1 SE is a simpler K1. Keychron's page lists an 80% TKL, Bluetooth plus wired at 1000 Hz, hot-swappable low-profile Gateron mechanical or Keychron optical switches, an ABS-and-aluminum tray-mount case, LSA ABS keycaps that are not shine-through, a four-level backlight, a 2000 mAh battery rated up to 190 hours, about 550 g and 355 x 120 mm. The spec table lists macOS, Windows and Linux support but does not mention QMK or the Launcher.
No review of the SE was found. AppleInsider's K1 Pro review is the nearest evidence on the line: it praised the slim TKL, stabilizers with no spacebar wobble and three-step feet, although the Pro has QMK/VIA and PBT keycaps that the SE does not list.
The SE is for people who want the lightest, longest-lasting K1 and do not need programmability.
