Redragon K673 PRO: problems, parts and running costs
Checked: 2026-10-08
Summary
The most common issues are switch noise and build-quality compromises rather than outright failures: Tom’s Guide called the board noisy and flagged quality-control issues while praising its value. The one spec to check before buying is the battery, because Redragon’s own pages disagree between 4000 mAh and 3000 mAh.
Common problems and fixes
- Noisy switches — Tom’s Guide lists the board as noisy despite the five-layer dampening, which likely refers to switch sound rather than case reverberation; one Reddit owner of seven days said it sounds better than a K599 Demios and has better sound dampening. The practical fix is swapping switches: the hot-swap sockets take standard 3-pin and 5-pin switches without soldering. Warranty terms for this model are not confirmed from primary sources. [3][6]
- Programming needs a cable — software customization requires a USB cable connection; wireless mode only runs the stored configuration. Wire the board up for any remapping or lighting changes. [5]
- Warranty terms unconfirmed — only the related UCAL MAX K673 lists a 2-year limited warranty; the K673 PRO pages retrieved do not state terms. Confirm coverage on the order page before relying on it. [1][4][5]
Parts and consumables
- Internal battery, 4000 or 3000 mAh — the capacity conflict between sources is unresolved; no replacement-battery channel or battery-swap procedure appears in the research, so treat end of battery life as a replacement event for the keyboard. [4][5][9]
Yearly running cost
There are no consumables and no scheduled replacement parts, and the box already includes a set of five replacement switches. The only running cost is electricity for charging, but the research contains no charge current or electricity rate, so there is no dollar total to publish; estimate it as the 4000 mAh (or 3000 mAh) pack charged as often as your wireless use demands, times your local rate per kWh. [4][5]
When it is a good buy
- $50 or below: strong value. Tom’s Guide reported the blue colorway at $49.99 at Newegg and at Walmart (October 2024), and the review noted the price frequently drops to about $50 in sales. Tri-mode wireless, gasket mount, hot-swap, PBT keycaps and a control knob all land at this price. [3][5]
- $51-65: still good value for the feature set. Best Buy listed the blue and red colorways at $64.99 (October 2024), and Redragon’s K673 collection lists the UCAL K673 PRO at $64.99 (October 2026). [3][8]
- Above $65: fair. Compare other budget mechanical keyboards that may offer better build quality or clearer warranty terms. [3]
Alternatives:
- Redragon K673 HE Rapid Trigger — the better choice when you want magnetic rapid-trigger switches, but it is wired only, so you give up the tri-mode wireless that is this board’s main feature. [8]
- Redragon UCAL MAX K673 — the better choice when you want MOA keycaps, a different switch and a confirmed 2-year limited warranty; it is a different board, not a K673 PRO. [1][8]
- Side-printed PBT K673 PRO variant — $69.99 in Redragon’s K673 collection (October 2026); the better choice when you want side-printed legends. [8]
