Keychron K5 V2 vs K5: your questions
The K5 V2 adds QMK firmware support for custom keymaps and macros and includes enhanced acoustic foams (IXPE, EPDM, latex) for a quieter typing sound. The original K5 lacks QMK and acoustic foams but is available at a lower price and offers a Keychron optical switch option that the V2 does not support.
No, the K5 V2 is only compatible with Gateron/Keychron low-profile 2.0 mechanical switches. The manufacturer states that QMK firmware does not support low-profile optical switches, so they are not an option on this version.
The Keychron K5 V2 has a 1000 Hz polling rate in wired mode, which is better for low-latency gaming. The original K5's polling rate is not specified in the provided data, so the V2 offers a clear advantage based on available information.
The original K5 does not support QMK firmware, so it does not offer deep key remapping or macro customization. The K5 V2, on the other hand, includes QMK and the Keychron Launcher web app for full customization of each key.
Both keyboards have a 2000mAh rechargeable battery. For the K5 V2, the vendor lists Bluetooth working time as up to 160 hours with backlighting off and up to 105 hours with RGB at lowest brightness. Battery life for the original K5 is not specified in the provided data.
Yes, a hot-swappable version of the K5 V2 is available, allowing you to change Keychron low-profile 2.0 mechanical switches without soldering. The original K5 also has a hot-swappable version, but it is compatible with Keychron low-profile optical switches, not mechanical.
Yes, both the K5 and K5 V2 support macOS and Windows, and they include keycaps for both operating systems. The K5 V2's Keychron Launcher is also compatible with Linux.
Both keyboards have identical dimensions (424mm x 119mm) and weight (732g), making them equally portable. They both feature a low-profile design and a 2000mAh battery for wireless use.
Some user reviews for the original K5 mention Bluetooth disconnection issues. The K5 V2 addresses this by upgrading to Bluetooth 5.2, which is marketed as more stable, but long-term performance data is not yet available.
The K5 V2 is available with Keychron low-profile 2.0 mechanical switches in Red (linear), Brown (tactile), and Banana (tactile). The original K5 offers a wider selection, including Gateron low-profile mechanical switches (Red, Blue, Brown) and Keychron low-profile optical switches (Red, Blue, Brown, Banana, Mint).
