How much electricity do you need to power a sewing machine effectively? That’s excellent to understand if you have actually lost the converter, or possibly you intend to make use of the machine during journeys.

Right here’s just how much electricity sewing equipments use:

A sewing machine usually utilizes 100 Watts. Some older versions only 85 as well as some big sector versions may make use of up to 180 Watts. You will certainly have around 120 or 220 Volts as well as after that the number of Amps will vary. Below’s what you need to know.

However there are some cautions obviously. A few facets you require to take into consideration when we are seeking adapters for sewing makers. Or if you wish to power your machine with electricity from a generator or battery

Let’s take a more detailed look.

Exactly how much power does a sewing machine take in?

To know how much power your machine consumes, you need to discover the number of Watts

Many sewing, overlock, quilters, needlework, and those types of machines use 90-110 Watts. Some industry models will certainly utilize more power and get closer to 160 or 180 Watts. Yet that would certainly not hold true for your normal house sewing machine

Some older machines will utilize much less Watts.

We found an old Bernina sewing machine from around 1970 that would just draw 80 Watts. However, let’s stick with the 100 Watts number, and also take a look at some math, to calculate the number of kWh and also the price of sewing on the machine

If you sew 3 or each day 5 days each week, that will certainly be 15 hours of sewing per week. That will certainly be around 65 hrs monthly. As, well as let’s assume your machine usages 100 Watts. After that you will certainly make use of 65 x 100 Watts each month = 6,500 Watts. That’s the very same as 6.5 kWh.

1 kWh expense 12 cents on average in the United States (discover your state here , so the cost is 6.5 x 12 cents = 78 cents. A typical U.S. house uses concerning 908 kWh a month of electricity, so the sewing machine is not a trouble when it pertains to power intake.

Watts = Volts * Ampere Kilowatt (kW) = 1,000 watt, so 100 Watt amounts to 0.1 kW.

What if I can not find the Watt number?

You can normally discover the number of Watts provided on the little sticker on the back of the machine (scroll down for an example). It will tell you things like Watts, Volts, and Ampere. These are the number we want in order to recognize (or compute) the power intake.

If you can not discover the number of Watts on the back, possibly you can locate the Ampere number. When you increase the number of Ampere by the variety of Volts (usually 120 for the U.S as well as 220-240 for Europe), you will have the variety of Watts.

The electric motor makes use of most of the power

The motor in the sewing machine uses most of the power. So the numbers (Watts, Volts, as well as Ampere) you see on the back of the machine is in fact simply the specs for the motor. The

The little lamp on the machine is one more story. It will just make use of around 10-15 Watts. The machine will have an integrated system to take treatment of that, so you do not need to take that into factor to consider. That’s a very percentage of Watts as well as not something that will ever be a trouble.

Using a sewing machine on watercrafts, in RVs etc.

If you want to utilize your sewing machine on a boat or in an RV, or anywhere else you are off the power grid, that should be a simple thing. It does not call for much powers, as well as it’s a wonderful product to be able to bring whether you need to hem a curtain or similar to loosen up with a little sewing project.

You can attach the machine to your batteries, inverter, generator or what you make use of. You can use your sewing machine on the go if you have the ability to power various other electric equipments as well as devices.

As we looked at, the sewing equipments only use 100 Watts. That’s a lot less than many other makers we frequently bring in the recreational vehicle or on the boat:

  • Sewing machine: 100 Watts
  • Television or flatscreen: 50-1000 Watts (This depends solely on the dimension of the display.)
  • Microwave: 800-1200 Watts
  • Light bulbs: 40- 100 Watts
  • Food blender: 300 Watts)

So the mini stove will take in 8-12 times the quantity of power than your sewing machine will certainly use. However understand that the sewing machine will certainly use up even more power than the microwave at some point since you will certainly utilize it for a longer period of time.

You need to take the quantity of time it will be running into account as well. So if you are sewing for hrs you might end up draining your batteries anyhow.

So make certain you take that into account before you start preparing a lengthy journey in front of the sewing machine (in your RV or on your watercraft).

How to select the proper adaptor for your machine

If you are utilizing the sewing machine interior, and have accessibility to connect it in , you simply require the appropriate adaptor. You don’t have to make use of the initial adopter, as long as the numbers match. So if you have shed your adaptor you can make use of an additional. But be mindful that the guarantee may not cover any damage from use unimaginative adaptors.

So if you can find a brand-new original adaptor that will constantly be the best option.

It that’s not possible, let’s look at what you can do rather, to get that machine going as promptly as possible.

When you check out the back of the machine it will certainly say something such as this: These stickers are from the rear of our Pfaff sewing machine as well as Bernina overlocker. It states 90 Watts and 105 watts. It also states that if you have 220-240 Volts you will certainly need 0,5 Ampere. (You may keep in mind that when you multiply the variety of Volts and also Ampere you have the number of Watts.)

Discover the sticker on the back of the machine, and locate these numbers.

So as lengthy as you select an adapter that supplies at least 100 Watts you must be excellent to go. The adaptor is usually constructed right into the pedal, as well as our adaptor actually gives 150 Watts as well as not 100.

It can be a little difficult to power the machine with a different type of adaptor, as it will probably not fit into the outlet on the machine

Take care concerning altering the plug of the electric cable, because you require to know exactly what you are doing. If you are not connecting everything correctly, it may be a fire-trap. You don’t want cables laying around which are not sealed properly, due to the fact that they might stimulate a fire.

Constantly consult a professional or take your sewing machine to a certified service center, if you are not experienced with these kinds of points.

What regarding Volts as well as Ampere?

Your sewing machine is connected right into 110-240 Volts, and also now we understand that it requires 100 Watts, we can calculate the appropriate amount of Ampere.

Let’s consider an example.

Example We understand that your sewing machine needs around 100 Watts. If you have 120 Volts you will certainly require 0.86 Ampere. If you have 220- 240 Volts, you will just need 0.43 Ampere.


As a result of the number of Volts * Ampere = Watt. (120 Volts x 0.83 Ampere = 100 Watts)

That’s how you compute the power intake of any kind of digital gadget. The sewing machine is light-weight when it involves power consumption yet it does require to be connected in. You can not run it with standard batteries.
