If you are wondering how many watts does a jigsaw use, the short answer is that a typical corded model is rated between 350 and 850 watts, which works out to roughly 3 to 7 amps on a 120 V outlet. That rating is the ceiling the jigsaw motor is built to handle, not what it pulls every second, so the figure you actually see on a power bill or a generator display is usually lower.
A jigsaw power rating is printed on the nameplate in watts, and it tells you how hard the motor can work before it overheats. A hand-held jig saw is a lightweight power tool, so most of the weight and cost of a bigger rating goes into a stronger motor and a sturdier housing. The ranges below show where most jigsaws land for each kind of buyer.
| Type of user | Typical wattage | Approx. amps at 120 V | Best suited to |
|---|---|---|---|
| Occasional users | 400 W | 3.3 A | Thin plywood, trim and a few weekend cuts |
| Regular users | 550 W | 4.6 A | Laminate, shelving and kitchen worktop cutouts |
| Serious DIY | 700 W | 5.8 A | Thick hardwood and long cuts in aluminium |
| Professional | 850 W | 7.1 A | All-day work on wood and steel |
Treat the table as a guide, not a promise. Two jigsaws with the same rating can feel different once you add a different blade, a different stroke length or a heavier base plate.
Any motor draws more electricity for the first fraction of a second than it does once it is spinning. Running wattage is the steady draw while you cut, and starting wattage is the short burst needed to overcome inertia and get the blade moving.
Think of the running figure as the cruising speed and the start figure as the push you give a stalled car. A small electric jigsaw may need about twice its running draw for a moment, which is why a surge can trip a weak breaker or stall a small generator even though the saw is fairly modest on paper.
If you only add up running figures, you will under-size your supply. You need the highest start demand in your lineup plus the running load of everything else that stays on at the same moment.
Many sellers list jigsaw amperage instead of watts. A shopper might see a range from 3.6 to 7 amperes on a store shelf and wonder what changed. The link is simple: watts equal volts multiplied by amps, so you can convert in either direction.
$$P = V \times I$$
For a saw rated at 5.5 A on a 120 V circuit, \(P = 120 \times 5.5 = 660\) watts. Higher amps usually mean the motor can run longer without getting hot, which is why the nameplate matters more than the box slogan. The phrase power factor and a few other losses can nudge the true figure slightly, but for a brushed motor this simple product is close enough for planning.
The power rating can also be written in kilowatts. A 660 W saw is 0.66 kW. Heavy industrial equipment or an old appliance sometimes quotes horsepower instead, and one horsepower equals about 746 watts, so a hand tool that is rated around one horsepower would sit near the top of the range.
To find your power consumption in kilowatt-hours, multiply the wattage by the hours of use and divide by 1,000. Multiply that by your local rate to get the cost.
$$E_{\text{kWh}} = \frac{P \times t}{1000} \qquad \text{Cost} = E_{\text{kWh}} \times \text{rate}$$
Say your saw draws 660 watts, you cut for 40 minutes in a single session, and your electricity costs $0.16 per kWh.
Spread over a year at two hours a week, that is about 104 hours, 68.6 kWh and roughly $11. In other words, running a corded saw barely registers on a bill.
A corded jigsaw plugs into a standard wall outlet and quotes its strength in watts. A cordless jigsaw quotes voltage instead, because its power comes from a lithium-ion battery pack. Most cordless models use a 12 or 18-Volt pack, and an 18V platform is the most common for general work.
To compare a battery with a watt rating, multiply volts by amp-hours to get watt-hours. A 5.0 Ah pack at 18 V stores 90 Wh. If the saw averages 150 W while cutting, the pack runs for about 36 minutes of real cutting. Those numbers are an illustration, so check the manual for your own tool. A second battery on the charger keeps you working.
The corded type is the better pick for dense stock because the supply is continuous, while the cordless version wins in hard-to-reach areas and on roofs where a cable gets in the way.
The rating is only one input. The actual draw changes with how you use the tool:
Pushing too hard is the most common cause of overheating. Let the blade do the cutting and the draw stays closer to the low end of the rating.
Wattage describes motor power, but how that power becomes motion depends on speed and stroke. Cutting speed is measured in strokes per minute, also written as strokes/minute or SPM. Slow speeds around 500 to 1,000 suit tiles and glass, medium speeds suit plastic and non-ferrous metal, and fast settings above 2,000 are for wood.
A longer stroke length moves the blade farther on each pass, so the cut is faster and the teeth stay cooler. Orbital action, sometimes called pendulum action, tilts the blade forward on the up stroke and back on the down stroke. That clears chips, but it also asks a little more of the motor, so turn it down for fragile laminate. In short, stroke rate and orbital setting change how much of the rated wattage the saw actually draws.
A handy power consumption chart helps you see where this saw sits among your other tools. The figures below are rounded planning values, and your own models may differ.
| Tool | Typical running watts | Typical starting watts |
|---|---|---|
| Jigsaw | 650 | 1,300 |
| Corded drill | 600 | 1,200 |
| Circular saw | 1,400 | 2,800 |
| Miter saw | 1,300 | 2,600 |
| Router | 1,100 | 2,200 |
| Random orbit sander | 350 | 700 |
A circular saw is the usual comparison, and it asks for roughly double what a jigsaw does. A drill and a small sander sit nearer to the jigsaw, while a router and a miter saw belong in the heavier group. This is why the jigsaw is the gentlest option on a shared circuit.
On a job without mains, sizing a generator means adding the running watts of everything on, then substituting the biggest start demand. A site that uses a 650 W saw, two work lights at 150 W and a 1,050 W shop vacuum would work like this:
A 3,500 W unit would therefore be a safe choice. A jigsaw is a single-phase 120 V load, even on a larger construction site or a commercial workshop where three-phase supply is common. When the setup is complicated, ask an electrician to measure the real load, and check the owner's manual or the tool's nameplate for exact numbers rather than leaning on estimates.
Use this short buying guide to match the saw to your work instead of buying the biggest number on the shelf. Compare with how much energy does a leaf blower use.
For occasional users cutting plywood and trim, around 400 to 500 watts is enough, and a basic DIY model keeps cost down. Regular users fitting a kitchen or laying parquet should look near 700 watts. A professional who cuts all day will want 700 watts or more, plus an extraction system for dust extraction and a rugged sole plate.
A tool-less blade change speeds up swaps, a T-shank blade fits most modern models, and a bevel setting lets you tilt the base to cut mitres. Look for a hand-held body that stays lightweight, and a warranty of at least a year or two. None of these raise the electric draw, and variable speed actually lets you lower it on delicate work.
Material is the biggest reason two identical jigsaws pull different current. Cutting wood is the job most jigsaws are built for, and soft pine slides past the blade so easily that the motor loafs. Dense hardwood, thick laminated panels and wet timber all raise resistance, and the saw answers by drawing more current. When you move to steel or any other metal, the draw climbs again, because the teeth bite slowly and the motor has to keep turning against a firm, constant resistance.
Metal is where the current draw peaks. A mid-range saw can manage about 10 mm of steel, but the motor sits near the top of its rated watts the whole time and will run hot if you rush. For long metal cuts, pause often so the motor and blade can shed heat. Cutting wood needs the opposite approach: a fast stroke, light pressure and a sharp blade.
Before a job, sort your materials by thickness and density, because that order decides how much power you pull. Mixed materials in one session, such as a thin panel followed by a thick slab, are where people forget to change the speed dial, and a motor left on a fast setting in dense stock draws close to its full rated wattage for the least reward. A short cut list on the bench, with the toughest pieces first while the blade is sharp, keeps the draw down and saves time.
Jigsaws also handle plastic, ceramic and wall tiles when fitted with the right blade. These materials are brittle, so the best results come at low speed. A slower stroke generally means a lower draw, so cutting tiles is often gentler on a supply than cutting hardwood, even though the job feels slower.
Tools turn electrical energy into motion, and any resistance that the blade meets must be paid for by the motor. That is the reason a nameplate rating describes a limit and not an average. Two jigsaws with different ratings might draw nearly the same current on a sheet of thin plywood, and then differ widely once both are cutting thick wood or steel.
A household circuit has a limited capacity, and a jigsaw is only one of the appliances that may share it. A typical 15 A branch circuit on a 120 V supply can carry about 1,800 W, so one 660 W saw leaves a lot of room. Trouble starts when the saw shares the circuit with a space heater, a vacuum or a freezer compressor, because their loads add up, and the saw's brief surge lands on top. Next, look at roti maker power consumption.
Most home workshops have no issue at all, since jigsaws are among the lighter tools in the garage. Shops with several machines are different, and a sensible habit is to run one heavy tool at a time.
Sharp blades, light pressure and a clean motor vent keep the draw low. Blow sawdust out of the housing after a long job, because a clogged vent forces the motor to run hotter and draw more amps. Store spare blades in the case, so you replace worn ones promptly. Over a year, small habits like these lengthen the life of jigsaws and cut the repair bill.
Good safety habits are also efficiency habits: a clamped workpiece lets the saw cut without fighting vibration, and removing the battery before a blade change prevents accidental starts. For better efficiency and steady performance, choose the right blade for each of the materials you cut: plastic, ceramic, tiles and laminate each want a specific tooth pattern. A wrong blade adds heat and pulls more current, so it is a wasteful way to work. Keep the cord clear, avoid extension leads that are too thin, and let the base plate rest flat on the workpiece.
Once you know these terms, every label on a saw, charger or generator becomes easy to read, and the question of how much power your next project needs becomes a short sum.
