Redragon K745 PRO: problems, parts and running costs
Checked: 2026-10-19
Summary
No widespread failure modes are reported for the K745 PRO; the issues that come up are a flexing all-plastic case, typing comfort without a wrist rest that is not included, and F-keys that need the function lock toggled [4]. There are no consumables, so the yearly running cost is just the electricity for charging the 4000 mAh battery, which the sources do not quantify. It is a strong buy below $60, competitive up to $70, and weak above $85, where keyboards with independent testing and proven reliability become available [1][2][5].
Common problems and fixes
- Proprietary software, no QMK or VIA — Redragon’s software is proprietary and no QMK or VIA compatibility is mentioned, so deep remapping depends on Redragon’s own tool [2].
Parts and consumables
Yearly running cost
There are no consumables — no filters, pads or subscriptions — so consumables cost $0 per year. The only running cost is the electricity to charge the 4000 mAh battery, which the sources do not quantify. One-off costs: spare Mint Mambo switches if the four included spares run out (no price reported). Battery and PCB work is not documented as user-serviceable, so a dead battery is a warranty matter — 18 months in South Africa, US terms unconfirmed [3].
When it is a good buy
Redragon’s US store lists the board at $69.99 (October 2026) [1]; Redragon’s own review and a Reddit buyer cite $64.99, apparently an earlier or sale price [2][5].
- At $60 or below: strong value — a gasket mount, tri-mode connectivity, hot-swap sockets and PBT keycaps are rare at that price.
- $61-70: competitive value at the current direct pricing.
- $71-85: fair value; compare against boards with more established review coverage.
- Above $85: weak value; keyboards with independent testing, proven reliability and stronger warranty support become available.
No alternative keyboard models are named in the research inputs, so no model-by-model comparison is possible.
