You can use it, just make sure that the polarities are the same as the original.

I have this same wheel. The information off of the power supply: Model: AD-48130850, Input: 120V AC 60Hz 0.3mA., Output: 13V DC 850mA. Hope this helps.

I believe it is 12V 1.25A (you can use 12V 1.5A or 2A) Probably centre +ve, but look carefully at the scanner where the power lead plugs in, it may show the polarity and voltage on the plastic near the hole. Please report back? regards

All you need to know is:
- The output voltage (usually 12V)
- The rated output current (usually above 5A)
- The plug polarity (usually plus on the inside)
Then just purchase any replacement AC adapter that has the same voltage, same plug polarity and rated current preferrably more (at least 120%) of the original.
That's it.
You can buy them online, for example at http://www.12vadapters.com/

You need about 14 volts to charge a 12 volt battery. The original charger MAY have some form of current limiting in it.

ALSO pay attention to the polarity of the charger.

Output voltage on PS is -(negative)19 Vdc at center pin. 12 volts will work if you have the right size plug.

Yes the adapter must have an output of 12vdc AND rated for a least 4.0A output!
