Winner: Logitech MX Mechanical ($159.99, logitech.com, 2026-09-06, in stock) — it's the only true full-size board with an integrated numpad verified in this catalog, and it's built for all-day office use: up to 15 days of battery with the backlight on, or roughly 10 months with it off. Runner-up: Keychron V5 Max ($109.99, keychron.com, unchanged across the 2026-08-26 and 2026-09-06 checks, in stock on both; 96% with a rotary knob) — $50.00 cheaper, adds a 2.4GHz radio and USB-C wired mode the MX Mechanical lacks, plus QMK/VIA and hot-swap sockets, at the cost of a slightly narrower layout and an ABS rather than metal-toned body. Caveats: neither board has been typed on by us, every figure is a manufacturer specification read on the date given, the MX Mechanical's price rose between the 2026-08-26 and 2026-09-06 checks, and prices change without notice.
The limits first: neither board has been typed on by us, every figure below is a manufacturer specification read on the date given, and prices and stock are the 2026-09-06 re-check unless a line names 2026-08-26. The MX Mechanical (full-size, integrated numpad) connects over Bluetooth Low Energy or a Logi Bolt 2.4GHz receiver, but its USB-C port is for charging only — there is no wired data mode, so it can never be used tethered. Each SKU ships with one fixed switch type (Tactile Quiet, Clicky, or Linear) and is not hot-swappable, so the switch feel you buy is the switch feel you keep. Its 1500mAh battery is rated up to 15 days with the white backlight on, or about 10 months with it off, helped by a hand-proximity sensor and ambient-light auto-adjust; it weighs 828g and carries a 1-year limited hardware warranty.
The V5 Max is a 96% layout with a rotary knob — a numpad without quite the full width of a true full-size board. It runs full tri-mode connectivity (2.4GHz, Bluetooth 5.1, and USB-C wired) at 1000Hz on 2.4GHz and wired, dropping to 90Hz over Bluetooth. QMK/VIA firmware and MX-standard hot-swap sockets are both present, running Gateron Jupiter Red switches on this variant, in a gasket-mounted ABS body with a PC plate. Its 4000mAh battery is rated up to 190 hours with the backlight off or 100 hours at the lowest RGB setting — shorter on paper than the MX Mechanical's, though it's driving RGB rather than a single white backlight.
The trade is straightforward once you name it: pay $50.00 more for the MX Mechanical and get an unambiguous full-size layout, months instead of days of battery, and a proximity-sensing backlight — but you give up hot-swap, QMK, and any wired connection. Pay less for the V5 Max and get open firmware, swappable switches, and a wired fallback for when the battery does run out — but you give up true full-size width and the MX Mechanical's multi-month battery ceiling.
Both were in stock at the 2026-09-06 re-check (logitech.com for the MX Mechanical, keychron.com for the V5 Max), as they were on 2026-08-26, so this is a straight feature-and-price call, not an availability one. Who this is NOT for: anyone who wants to change switches later on a genuinely full-size board. The MX Mechanical has no hot-swap sockets and ships one fixed switch type per SKU, and the only hot-swap option here is the V5 Max, which is 96% rather than true full-size. It is also not for anyone who needs a wired data connection — the MX Mechanical's USB-C port charges only.
