WalkingPad A1 Pro vs P1

Most comparisons of these two machines spend four hundred words on specifications that are byte-for-byte identical on KingSmith’s own pages. Here they are once, so you can ignore them:

• Footprint in use: 56.5 x 21.5 x 5 in on both.
• Folded: 32.5 x 21.5 x 5 in on both. Neither gets shorter or taller than the other when stowed.
• Belt:47 x 16.5 in on both — the widest in the KingSmith range.
• Top speed: 3.75 mph on both.
• Incline: neither has one, and neither publishes a figure.
• Handrail: neither has one.

If storage, desk clearance or stride length is your constraint, these two machines are interchangeable and you should choose on price alone. Where a 32.5 inch folded length actually fits.

KingSmith publishes “under 65 dB” for the A1 Pro and publishes nothing at all for the P1, the Z1 or the C2. Of the eight walking pads on this site, exactly two have a decibel figure of any kind, and this is one of them.

Be precise about what that buys you. There is no stated test distance, no belt speed, no user weight and no floor surface behind the figure, so it is not comparable with the Lifepro PacerMini’s “less than 60 dB” and it is not a measurement in the sense a meter would give you. What it is, is a commitment in writing from the manufacturer — which is more than six of the eight makers here were willing to give.

It also answers the wrong question for one of the two rooms people buy these for. In a home office, airborne motor noise is the whole problem and a published figure is genuinely useful. In an apartment, the complaint comes from downstairs, and what reaches them is footfall energy through the floor structure rather than motor noise through the air. The full argument, with what each figure does and does not describe.

Reading KingSmith’s own spec tables on 2026-08-18, the P1 is published as 0.3 – 3.75 mph and the A1 Pro as 0.5 – 3.75 mph. Both listings lead with the top speed, and the top speed is the number that will not matter to you.

Typing accuracy degrades with pace well before walking becomes hard work, so the useful range at a desk sits at the bottom of the dial. 0.3 mph is a shuffle — it is the slowest published start on this site, by a clear margin over most of the field, and it is the setting that lets you keep moving through detailed keyboard work instead of stepping off.

0.2 mph sounds like nothing. As a proportion of the useful desk range it is not nothing at all: it is the difference between a machine whose slowest setting is already a walk and one whose slowest setting is barely movement. Why minimum speed is the specification to check.

230 lb against 220 lb. On its own that is a marginal difference and it only decides anything if you are within about 20 lb of either figure — in which case it decides everything, because a published capacity is the one figure on a spec sheet you should never treat as approximate.

The more useful point is that KingSmith sells the A1 Pro in a 300 lb capacity variant alongside the standard model, and offers no equivalent for the P1. If capacity is your constraint, the A1 Pro is not 10 lb better than the P1, it is a line with somewhere to go. Every published capacity on this site, ranked.

Read on 2026-08-18, KingSmith publishes the A1 Pro’s motor as 3.75 HP brushless and the P1’s as 746 W. Both machines are 110 V.

746 W is exactly one horsepower. So the same manufacturer, on the same website, describes two machines with the same belt and the same top speed as 3.75 HP and 1 HP. Those figures are not measuring the same thing — one is a peak or marketing number and the other looks like a rated input — and neither page says which.

Our conclusion is not that one motor is better. It is that the motor specification in this category is not comparable, even inside a single brand, and should not be a factor in choosing between these two. What those numbers imply about running cost, where a genuine 3.75 HP draw at 110 V would need roughly 25 amps.

Buy the A1 Pro ifthe pad lives in a room where you are the listener — a home office, a shared room, anywhere you take calls — or if you are near the top of the capacity range. The published decibel figure is the only piece of noise evidence available in the KingSmith range, and the 300 lb variant exists.

Buy the P1 if the machine is primarily a typing machine. The 0.3 mph floor is a real, daily difference in what work you can do while it runs, and it is the specification most likely to decide whether the pad is still out in six months.

Buy neither if your constraint is storage or carry weight. At 62 and 63 lb these are the two heaviest KingSmith pads, and the Z1 folds 0.7 inches shorter and weighs 11 lb less — at the cost of 0.8 inches of belt width.

We have not walked on either machine. Everything above is read from KingSmith’s published specification tables on the dates in the sources below, and the arithmetic is arithmetic you can redo. Our full method.
