the wattage is on the plate attached to the drill and will still be the same as before you attach a step down transformer to get to the correct voltage

get a step down transformer that has a large wattage rating for 120 volts ( say 1200 watts ) as most 1/2 drills are 750 -1000 watts )

the wattage is for the rated current through the transformer and if the drill is of low wattage , it just gives the transformer a greater degree of serviceability in the duty cycle

Yes you can.

Make sure the transformer is rated for more power than the drill label states so that you don't burn up the transformer if you stick the drill bit.

For instance, if the drill is rated for 5 amps at 230 volts you should get a 1500 watt transformer. 230 x 5= 1150 watts; the next common size up is 1500 watts. You don't want an 1200 watt if it is available.

Transformers are also rated in KVA [Killovolt-amps] so the same transformer would be 1.5 KVA.

Do the math for your drill and save future problems. If a transformer doesn't have a rating with real numbers, avoid it. There are lots of really cheap ones on the market that you will regret buying.

VT 2300F Step Up Down Transformer with American Grounded Plug 2300 Watts

The wattage rating for the router is just under 2000 watts. You'll want a converter with a wattage rating more than the rating of the router.

VT3000 Step Up Down Voltage Transformer 3000 Watts

I would personally go for the 3000 watt converter.

I hope you're talking about a step down transformer. Your drill needs 550 watts to run but probably 700 to start. If you try using your drill connected directly to 220 it will fry in your hand. Even if you do use a step down transformer the motor will heat up faster because it's running on 50 Hz.

All the information you need is in your text :>)

Volts, Amp Watts To determine the wattage, use a simple multiplication formula. The ampere (or**amps**) is the amount of electricity used. Voltage measures the force or pressure of the electricity. The number of **watts** is equal to **amps** multiplied by **volts**.

If your microwave is wired for 220 volts AC and your country standard house current is 220, and the plug is of the proper configuration, plug it in.

Standard microwave size is around 1100 watts at 110 volts Normally, two times the voltage is 1/2 the wattage. Ohms law, Voltares Law and Watts Law apply.

If your microwave is 1100 watts at 110 volts --- yes you will need a step- down transformer of some type.

Hi there!

I am afraid you can't do that by the changing plug. However, you can do that by using a Step-down Transformer which will bring 220V to 110v that is what your machine is designed to run on. Check the wattage of your drill before getting a Xformer. Usually the stepdown x-former should have a proper socket at the output side. Good luck.

I'm disappointed that Dewalt does not have the full specs on their website so . . .

Check the specifications on the charger's label; they should read something like 120 VAC or Volts AC and 2.0 (or similar) amperes or just 'A' after a numerical value.

If the label does not give you an amperage value you can use the output value instead and substitute the output voltage at the high end if a range is listed.

To get the adaptor (step-down transformer) wattage, multiply the AC values such as:

120 X 2=240 watts input power.

If these AC values are not available;

Take the high end charge voltage if it is a multirange charger, and multiply those values;

One we own DW9108 (- yours is 7.2 - 18) is spec'd at 9.6 to 18 volts and 2.8 amperes:

2.8 X 18=50.4 watts.

You can see that the values do not correspond but it is a multirange device so the maximum current taken from the AC line can be ~ 2.0 amperes but this is charging a specific pack and the peak input current is only momentary so the maximum output current and voltage are the values one should use as a guide. In other words, the output wattage is closer to the value needed.

Since there are losses in any transformation (mostly heat), the required stepdown transformer must be capable of more than the indicated 50 watts.

A safe factor would be 1.5 X 50 (W) or ~ 75 watts minimum to ensure the charger receives the 120 volts it wants.

Anything that will step down your (?) 220 volts and is rated at 75 watts or more will do the job even if the Dewalt draws a little more current at your line frequency of 50Hz which it may.

If your unit is from the USA, 120 volt/ 300 watts.

EU is 220-240V / 300 Watts. Best choice is to go to Bose service center in EU and have your transformer inside your box replaced with 220-240V for EU operation. That way you don't have to worry about a converter. If not, 2nd choice is buy a step-down transformer 220-240V input and 120 Volt output that can handle 300Watts.

Good Luck.

I brought a Black and Decker cordless drill to Thailand where the voltage is 220. in Canada, U.s we have 110V. The drill redudes thye 110 to 18V. I bought a QAC/AC conerter here. Output 110V. It is 50 Watt. Is this transformer o.K?
