Keychron B11 Pro vs V4 MaxUltra-Portable vs Customizable

The Keychron V4 Max has a significantly larger 4000mAh battery compared to the B11 Pro's 250mAh. According to Keychron's lab tests, the V4 Max can last up to 190 hours with RGB off, while the B11 Pro is rated for 138 hours. Actual use will vary, but the V4 Max has a clear advantage in battery capacity.

No. The Keychron B11 Pro is a pre-built keyboard with a low-profile scissor mechanism. It does not have hot-swappable sockets, and its switches are not user-replaceable. The V4 Max is designed for switch swapping with its hot-swappable PCB.

Yes, both the Keychron B11 Pro and V4 Max explicitly support macOS and Windows. The V4 Max includes an extra set of keycaps for both operating systems and a physical toggle switch. The B11 Pro uses its Launcher web app to configure keymaps for each system.

Both keyboards offer a 1000 Hz polling rate when using their 2.4 GHz wireless dongle or a wired USB-C connection. In Bluetooth mode, the polling rate is lower: 125 Hz for the B11 Pro and 90 Hz for the V4 Max, as stated in their respective specifications.

This depends on preference. The B11 Pro offers a low-profile, split Alice layout which can be more ergonomic for some. The V4 Max uses a gasket mount design with a polycarbonate plate and sound-absorbing foam, which aims to provide a softer, more cushioned typing feel with standard mechanical switches.

The vendor description for the Keychron V4 Max does not mention a carrying case being included in the box. It lists the keyboard, a Type-C cable, a Type-A to Type-C adapter, and keycaps/switches for the assembled version. The B11 Pro's foldable design is its own carrying solution.

Yes, the Keychron B11 Pro can be reprogrammed using the Keychron Launcher web app. This allows for remapping keys and creating macros. However, it does not support the open-source QMK or VIA firmware like the V4 Max does, which offers deeper, offline programmability.

The Keychron B11 Pro uses ABS plastic keycaps. The Keychron V4 Max, in its fully assembled version, includes double-shot PBT keycaps. PBT is generally considered more durable and resistant to oil and shine compared to ABS.

The Keychron V4 Max has features beneficial for gaming, including a 1000 Hz polling rate, N-key rollover to prevent ghosting, and a stable gasket-mounted construction. Its programmability also allows for game-specific macros. The B11 Pro also has a 1000 Hz rate but lacks N-key rollover as a stated feature.

The Keychron V4 Max supports connecting to up to three devices via Bluetooth 5.1. It also includes a 2.4 GHz wireless dongle for a primary connection. The keyboard comes with both a Type-C and a Type-A receiver, and it has a magnetic storage slot on the case to hold the unused dongle.

The Keychron B11 Pro uses a split, ergonomic Alice layout, which angles the two halves of the keyboard to align more naturally with the user's hands. The Keychron V4 Max uses a standard, non-split 60% layout where all keys are in a traditional rectangular arrangement.
