Keychron B1 Pro: Specs, Price, Pros & Cons
This review measures the Keychron B1 Pro against the full 34-spec sheet we track for keyboards, comparing it like for like with the 74 other models in our database. It earns a VS Score of 23 out of 100 — the weighted result of every verified specification measured against the class average.
On the spec sheet it is strongest in layout & size and weakest in switches & typing. Its clearest single advantage over the class average: 0.99 more connection — 3 vs 2.01 (avg). Street prices currently start at $ 39.99 for the Keychron B1 Pro. A transparency note: this spec sheet is 76% complete. Anything unverified shows as Unknown and is left out of the score — we never estimate a missing value.

Editor’s note
The B1 Pro is Keychron working at the opposite end of its range from the aluminium Q boards, and it is worth judging on its own terms rather than against them. This is a 5.2 mm scissor-switch keyboard weighing 425 grams, built to slide into a bag and pair with whatever device you are carrying.
Scissor switches are the same mechanism laptops use. Travel is short, the sound is soft, and there is none of the depth a mechanical board gives you. If you have only ever typed on mechanical keyboards you will find it shallow. If you type on a laptop all day and want that feel with a better layout and a proper wrist position, it is exactly right.
Battery is the standout. An 800 mAh cell with no backlight to feed is rated at up to eight months of use, and it recharges over USB-C in about two and a half hours. Tri-mode connectivity covers 2.4 GHz, Bluetooth 5.2 and wired, and it works across macOS, iOS, Windows, Android and Linux — useful if you rotate between a work laptop, a tablet and a phone.
The compromises are real and you should know them going in. There is no backlight at all, so this is a daylight or well-lit-desk keyboard. There is no N-key rollover, which rules it out for gaming that needs several simultaneous inputs. Bluetooth polling drops to 90 Hz, noticeably slower than the 1,000 Hz you get wired or on 2.4 GHz. And the keycaps and case are both ABS, which will develop a shine with heavy use.
At roughly forty dollars, none of that is unreasonable. Buy it as a travel or secondary board, or as a cheap upgrade over a bundled office keyboard. Do not buy it as your main gaming keyboard, or if you type in the dark.
Specifications
Quality bars are generated automatically against 74 other keyboards.
Switches & typing
The key switch technology; later types are generally more responsive.
The specific switch used (e.g. Cherry MX Red).
The force needed to register a key; lower is lighter to type on.
Swap switches without soldering.
Registers every simultaneous keypress.
Set the actuation point per key (analog / Hall-effect boards).
Keys report their travel depth for variable gamepad-style input and multi-stage actions.
Performance
How often the keyboard reports input; higher can reduce latency.
End-to-end keypress latency over a wired connection; lower is better.
End-to-end keypress latency over the fastest wireless mode; lower is better.
Resets a key dynamically as it moves, enabling faster repeated inputs.
Layout & size
The keyboard size and layout.
The number of keys.
The overall width.
The overall depth.
The front case height without keycaps; lower boards can reduce wrist extension.
The keyboard's weight.
Connectivity
The supported connection types.
How many paired devices it can switch between.
Battery life for wireless models.
The rated capacity of the internal battery.
A built-in USB port for other devices.
Build & sound
Keycap plastic; PBT resists shine and wear better than ABS.
The case material (e.g. aluminium, ABS plastic).
The switch plate material, which influences stiffness and typing sound.
How larger keys are stabilised (e.g. screw-in PCB or plate-mounted).
The plate / PCB mounting style (e.g. gasket mount).
Internal foam or dampening for a quieter, fuller sound.
The per-key lighting.
Features
Remap keys and record macros.
Dedicated volume and playback controls.
A control knob for volume or custom actions.
Stores layouts on the board itself.
Companion configuration software (e.g. VIA / QMK).
How the VS Score works — and what it can’t tell you
Every measurable spec is scored against the average of all the keyboards we track: matching the class average scores 50, clearly beating it climbs towards 100, and each spec counts according to an editorial weight that reflects real-world impact — a battery-capacity gap moves the score far more than a colour-options list. The quality bars on the spec cards above show where this model sits inside the full range for its class, and the overall VS Score rolls every weighted result into one number.
Unknown values are never estimated. A spec this product doesn’t report simply drops out of its scoring — it isn’t penalised with a guess — but a thinner spec sheet does mean a score built on fewer data points, which is why completeness is disclosed under About this data.
Most importantly: a spec-sheet lead is not the same as a better product. Megapixels, gigahertz and benchmark points describe capacity, not experience — image processing, software optimisation, thermals, haptics and ergonomics decide how a device actually feels, and no table captures reliability or long-term support quality. Treat the VS Score as a structured summary of what can be measured, not a substitute for your own priorities.
About this data
- Specifications are compiled from each manufacturer’s official spec sheet, cross-checked against trusted specification databases, and normalised into one schema so identical things are compared identically.
- Specifications last verified July 30, 2026.
- Data completeness: 26 of the 34 specs in this category are verified (76%). Anything we could not verify is shown as Unknown — never estimated — and is excluded from the score.
- Prices and availability come from live retailer feeds via our shopping partners and refresh throughout the day; a missing price means no partner currently lists the product, not that it is discontinued.
- Want the full picture? Our editorial guidelines explain how we research products, weight the scores and stay independent.
- Spotted an error in a spec? Tell us and we will correct the sheet.

The bottom line
The Keychron B1 Pro earns a VS Score of 23, trailing most of the 75 keyboards we compare here, at least on the spec sheet. It stands out for 0.99 more connection, 16.81 mm less front height and has configuration software. Just be aware of 2,683.33 Hz less polling rate and no n-key rollover before you buy. Weigh those trade-offs against what matters most to you.
The VS Score is generated automatically from the weighted specifications above, measured against all other keyboards in our database. Treat it as a shortlisting guide — not a substitute for your own priorities.
