What does a walking pad cost to run?

We read the manufacturer specification pages for the machines on this site on 2026-08-18, looking specifically for running power. Here is everything we found:

• WalkingPad Z1— “0.75HP Brushless motor”, 110 V. No wattage.
• WalkingPad C2— “3 HP Brushless motor”, 110 V. No wattage.
• WalkingPad A1 Pro— “3.75HP Brushless motor”, 110 V. No wattage.
• WalkingPad P1 — 746 W, 110 V. The only figure in watts anywhere in the range.
• UREVO Strol 2E— 2.25 HP. No voltage or wattage published on the page.
• Lifepro PacerMini— 0.5 HP, via the retail listing our other figures for that machine come from.

Not one of those is a statement of what the machine draws from the wall while a person walks on it at 1.5 mph. That figure — the only one relevant to your bill — is published by nobody in this category that we could find. What each brand publishes, and does not.

This is worth working through, because it is the clearest example on this site of a specification that looks comparable and is not.

One horsepower is 746 watts. That is a definition, not an approximation — and it means KingSmith’s published 746 W for the P1 is exactly 1 HP, stated in the other unit.

Now take the A1 Pro’s published 3.75 HP. As power that is about 2,798 W. On a 110 V supply, that would be roughly 25 amps— more than a standard household branch circuit provides. The machine plugs into a normal outlet, so it cannot be drawing that continuously.

And the C2, a smaller and cheaper machine than the P1, is published at 3 HP while the P1 is published at 1 HP equivalent. Whatever those two numbers are measuring, it is not the same quantity.

The conclusion is not that any maker is lying. It is that horsepower in this category is a peak or marketing figure with no stated test condition, and it should not be used to compare machines — the same conclusion we reached about the decibel claims, for the same reason. The two machines where this is most visible, side by side.

Three facts, each checkable, that together put a ceiling on the answer:

1. The circuit caps it. A standard US 15 amp, 120 volt branch circuit supplies at most 1,800 W, and everything else plugged into that circuit shares it.
2. The one published rating is 746 W. That is the P1, and it is a rating rather than a measured draw.
3. Actual draw at desk pace is lower than the rating. A motor rated for a load draws less when it is doing less work, and walking slowly on a flat deck is much less work than the rating implies.

So: 746 W is a defensible upper bound for a pad of this size while running, and the real figure is somewhere below it. We are not going to invent the real figure.

The rate: 18.44 cents per kilowatthour, the US total residential average for May 2026, from the EIA Electric Power Monthly, Table 5.6.A. Your own rate is on your bill and it varies enormously by state, so substitute it — the arithmetic below is deliberately simple enough to redo.

At the upper bound of 746 W:

• One hour: 0.746 kWh × 18.44 cents = 13.76 cents.
• One hour a day, 30 days: about $4.13.
• Two hours a day, 30 days: about $8.25.
• Four hours a day, 30 days: about $16.51.

Every one of those is a ceiling. The true numbers are lower, and for a smaller machine like the 0.5 HP Lifepro PacerMini they are lower again. Set against the purchase price of the machine, running cost is not a factor in this decision for most households. What the machines themselves cost, live.

The practical electrical question in an apartment is not the bill. It is whether the machine shares a circuit with something else that draws heavily.

A 15 amp, 120 volt circuit provides at most 1,800 W total. A space heater, a kettle, a microwave or a hair dryer can each take a large share of that on their own. Add a motor — which draws a surge at startup that is higher than its running draw — and a breaker can trip.

Three habits that cost nothing: plug the pad into a wall outlet rather than a thin extension lead, avoid sharing an outlet with a heater, and start the machine before you start the kettle rather than during. If your pad is already cutting out or taking the circuit with it, that is a specific fault pattern with a short list of causes. Walking pad keeps stopping or tripping the breaker.

If the actual figure matters to you — a very high electricity rate, a metered sub-let, curiosity — it is measurable in about five minutes and does not require any expertise.

A plug-in energy monitor sits between the outlet and the machine and reports watts in real time and kilowatthours over a period. Walk on the pad at the speed you actually use, read the watts, and you have the one number this entire category declines to publish. It is the same approach we take to noise: where the manufacturers will not measure it, the reading you take yourself is the only one that answers your question.

We do not sell energy monitors and we are not going to pretend a general-purpose electrical tool belongs in a walking-pad accessory list. Any hardware shop has them.

We have not metered a walking pad. Every figure above is either a published specification with its source and read date, a definition (1 HP = 746 W), a standard circuit rating, or arithmetic on those inputs. Where the honest answer is a bound rather than a value, we have said bound.

We have not estimated a typical draw at walking speed, because that would be a number with nothing behind it. Our full method.
