Different kinds of tools need different amounts of power. Knowing the right amount of power your power tool needs is essential. Ampere is the amount of electrical current that a motor can hold and carry indefinitely without damaging the electrical compounds of the tool. If you are unaware of how many amps your power tools use, you might end up tripping the circuit breakers, and you will not be able to calculate how long the battery will last. The tools’ functionality depends on their amps. But how can you find or calculate how many amps do power tools use? Continue reading to find out.

Generally, the small tools need 2-8 amps. Larger tools require 6-16 amps. In the cases of very powerful tools, the requirement can be more than 16 amps.

However, these numbers don’t give you the proper value. To check the precise value check the nameplate on the tool’s body. Mostly you will find the amps written there but if it is not written, you need to know the Volts and Watts to calculate amps.

Now you might be wondering what is Volts and Watts. Amperes measure current speed, whereas volts measure force, and watts are simply the measure of electric power. Now you know the meaning of these three terms, and you can easily calculate how many amps power tools use. To calculate the required amperage, divide the number of watts by the number of volts.

For example, A 120-watt device that requires 1,200 volts needs 10 amps. Let’s talk about some of the power tools and how many amps they use.

**How Many Amps Does a Drill Use?**

Most of the corded drills have amperage between 5 to 10 amps. If the Voltage input is 120V, it means 600 to 1200 watts. The latest cordless drills have enough power to perform a wide variety of tasks. The performance of cordless tools depends upon voltage, torque, and capacity. The battery provides the capacity and voltage. Higher voltage means that the tool can handle difficult tasks. To measure the capacity of a battery we use ampere per hour or Ah. A 3 Ah battery means that it can supply a current of 3 amps per hour.

**How Many Amps Does a** Saw Use?

**How Many Amps Does a**Saw Use?

There are different models of saws in the market for different jobs. You might need a saw for your hobby or maybe you need to fix something. We will discuss some of the varieties of saws and how many amps these power tools use.

- Circular saw: Nowadays, a standard corded circular saw uses 10 to 12 amps. Such saws are not appropriate for heavy use. If you need more cutting power, you can buy a circular saw of 15 amps or more. Cordless circular saws are rated by the voltage of their battery. 18 and 20-volt circular saws are available in the market. The Ah rating of these saws ranges from 5 to 9.

- Table saw: A professional table saw requires 15 amps for woodworking. A 15 amps table saw is powerful and you can enjoy the robust power of the saw. The smaller bench table saw requires only 13 amps of current to function.

- Miter saw: It is important to know how many amps do power tools use. When we talk about a typical 12 inches Single-Bevel Compound Milter saw, it usually uses 15 amps.

- Jigsaw: Corded Jigsaws use 3 to 8 amps. Jigsaw with more than 5 amps is optimal for heavy use. 12 to 20 volts cordless jigsaws are also available in the market.

**How Many Watts Does an Air Compressor Use?**

To determine the watts of an air compressor, the first step is to find the Voltage and amperage, check the handbook to get these details. Once you know the Voltage and amperage, simply multiply them to get the wattage. Usually, air compressors are 110-120V. So, a 110V air compressor generating 15 amps consumes 1,650 Watts.

**How Many Watts Does a Power Tool Battery Charger Use?**

An average power tool battery charger uses fewer watts than a corded tool. The exact watts used differ from charger to charger. Ryobi, Dewalt, and Kobalt battery chargers use different numbers of watts. In general, a 20V power tool battery charger uses 10 to 20 watts of power.

**How Many Amps Does ** an Impact Driver Use?

Most of the corded impact drivers use 5 to 8 amps but this value can change depending on the brand of power tool you are using. When we talk about cordless impact drivers, we can calculate the amps with the help of ampere-hour ratings. For example, a battery with a 2 Ah rating means an electric charge of 2 amps for 1 hour, 4 amps for 30 minutes, or 8 amps for 15 minutes.

**How Many Amps Does a** a Trimmer Use?

An electric hedge trimmer uses 2.5 to 4.8 amps. Battery-powered trimmers have a voltage rating which helps to determine the power a battery can produce. A typical 20V cordless hedge trimmer uses 1.5 to 2 amps.

**How Many Amps Does a** Lawn Mower Use?

Corded electric mowers usually draw 6 to 12 amps. On the other hand, the latest battery-powered lawnmowers are equipped with 12 amp engines. It means that 12 amps of current is constantly delivered to drive the engine.

**How Many Amps Does a** Leaf Blower Use?

One can find corded leaf blowers in the range of 7 to 12 amps. The amperage of a cordless leaf blower depends on the battery. The battery of a cordless leaf blower could range from 2Ah to 8Ah.

**How Many Amps Does ** an Angle Grinder Use?

The amperage of an angle grinder can range from 5 to 15 amps. A 5 amps angle grinder cannot be used for heave uses. If you want to use the tool for common use, an angle grinder that draws 10 amps is a good choice while 15 amps are suitable for heavy tasks.

**How Many Amps Does a** Sander Use?

Amps usage of a sander depends on the brand and model of the tool. Sander motors typically range from about 2 amps to more than 10 amps. On the other hand, the power output of a cordless sander is normally given in voltage, having a range of 16 to 20 volts.

Now you know how many amps do power tools use and how can you calculate the amperage and wattage your power tool requires. You should remember that the values given in this article are for power tools in general and amps rating can be different for different tools. So, it is advised to confirm the details written on the tool’s body or confirm from the manufacturer.
