This power supply takes any input from 100V up to 220V AC, which is what comes out of your wall socket, and output 9V DC.

FAQ – How to choose
In order to find the correct power supply for your device, you will need two pieces of information. These are Voltage (measured in Volts or V) and Amperage (measured in Amps or A). You can find this information off the back of the old power supply, or off the back of the device itself. If you do not find it on the device, you can check the manufacturer's website, or in the device's manual under "specifications".
All of the power supplies we sell are various from 5V to 24V DC. They take any input from 100V up to 220V AC, which is what comes out of your wall socket, and output 9V DC. So if your unit is not 9 Volt, you will need to find the correct adapter in our website.
Once you have confirmed that you need a 5 Volt power supply, you will need to find out how much power your device draws. This is called amperage. Next to the 5V in the specifications there will be another number followed by a capital "A" for Amps. You will need a power supply that can supply enough power for your device. If your device says it draws 3 Amp (3A), you need to use a power supply that can put out at least that many Amps. If your device states it needs 3A, then you can use a 3A, or 4A, or 5A unit. All will work.
If the Amperage of your device is uneven, such as 3.13A or 4.16A, always round up. 3.13A rounds up to a 3.5A adapter, a 4.16A device will round up to a 4.5A or a 5A.
This power supplies have a connector that is standard for a 5V DC device. Most 5V DC devices use the standard tip. This tip is 5.5mm (outer barrel) by 2.5mm (inner barrel) and is center positive. It is a simple round barrel connector. To repeat, if you match the voltage and amperage, then you should not have to worry about the connector type accept in the rare occasion when your device has an unusual connector such as a double barrel, or a 4-pin, but these are easy to spot as the jack where the adapter plugs in will not be a simple circular barrel with a pin inside.
