What voltage is your mains supply?
The laptop's adapter should be a multi-voltage type 110 to 240 volts input.
If your mains is 110 volts AC then the 220 volt AC LCD projector won't work unless you connect it to a step up transformer (110 to 220 volt transformer).
If your mains supply is 220 or 240 volts then both the laptop and the LCD projector will work without any problems.

How to convert 220 volts to 110 volts for the iPod Touch


<p> <p>The battery of an iPod Touch prepared for use in the United States is designed to be reloaded from the current supplied by a 110-volt electrical system. Power is transmitted to the battery charger with an iPod battery, which are connected via a USB cable and then connected to a 110 volt outlet. To use the power of a 220 volt outlet with an iPod Touch, set the current 220 volts to 110 volts. A conversion adapter voltage, also known as "Step Down Transformer," it is necessary and can be obtained from an electronics store, a hardware store and even some drug stores. <br /> <p><br /> <p>1. Place the 220-110 voltage converter card (aka, "Step Down Transformer") next to a 220 volt outlet. Plug the adapter into the outlet. <br /> <p><br /> <p>2. Connect the end of a USB cable to the USB connector USB iPod charger iPod. Connect the other end of USB cable into your iPod's own socket on the bottom of the iPod Touch. <br /> <p><br /> <p>3. Plug the iPod into the 110 volt outlet in the battery adapter for the iPod Touch. <br /> <p><br /> <p>4. Unplug the charger from the iPod adapter and the adapter from the outlet when the battery is charged. Unplug the USB cable from the iPod charger and iPod Touch. <br />

Will American power tool batteries work after being plugged into a 220 charger


Yep. they will as long as the 220 volt charger was connected to 220. If a 220 volt charger is plugged into 110 volts it may not charge the battery but no damage to the battery will happen.

Sabre 37in multisystem TV has blinking yellow light and won't turn on. Now in Europe, 220V. Should work fine.


TV's operate on 110 volts, not 220 volts. You need more than just an adaptor to plug in your TV. You need to use a voltage converter to bring the voltage down to 110 volts. But since you already connected your TV up to 220 volts, damage has already occurred to the sensitive electronic components and you need to get it repaired.

A 220 volt Amstrad monitor that i want to convert to use 110 volt


engagetek, This would be a very easy thing to do if and only if the label on the rear of the unit has printing similar to my GATEWAY LCD. It states as follows: "100 - 240VAC input 50/60hz." If your Amstrad unit's label reads "220-240VAC 50/60hz only, then you will need to reverse engineer the "ac to dc" power supply, be it an old "linear" or a modern "switch-mode-power-supply" type. You did not state what type of monitor technology your Amstrad is. CRT, LCD, Plasma,???? I would guess that it is a CRT type. Well anyway, I hope the info was of some use. Bye for now, I'm louie12fix on fixya

If you are attempting to connect your laptop between 110 and 220 volt power outlets, you may be able to do so already, take a look at your power cord's transformer (brick) and read the input voltage. If you only can use 110 volt AC Input Voltage should read 115VAC. If you can do both, then it should read 110-225VAC. 

If your power brick supports 220, then all you will likely need is a plug adaptor, found at many electronics store. If not, you wil need to stop in at a computer store or an import store and get an international transformer, which are set up to convert many different country plugs and many common voltages.

Good Luck!

Well, as a rule for electronics:
The United States and Canada use 110-volt electricity.
Most countries outside North America use 220-volt electricity.
Unless your appliance is dual voltage, you need to use a "converter" or a "transformer" to change the 220-volt electricity into 110-volt electricity in order to use a 110-volt appliance.
If your appliance is dual voltage, you can switch it to work on 220-volts, without a transformer or converter.

HOWEVER

Desktop units have a selector switch for 110 / 220 volts., which is done away with in the case of laptop one's which sense the input voltage and regulate accordingly.

I think your main concern is just that you have an adapter for the plug to go into the wall outlet.

Hope that helps :)
