Once you have selected your Brand and Model from the Search Wizard it will display the compatible PA3290U 1ACA AC Adapters under the product column. Once you have clicked on the battery you will be redirected to the page displaying all the information about the PA3290U 1ACA AC(http://www.udtek.com/toshiba-pa3290u1aca-ac-adapter-120w-19v-63a-p-25272.html) Adapter. Here are several tips on Selecting the correct PA3290U 1ACA AC Adapter.


The Voltage must be within 10% of your original PA3290U 1ACA AC Adapters Voltage. The Amps may be higher but they cannot by lower. If you are purchasing a universal PA3290U 1ACA  Adapter  or Car Charger you will need to work out the Watts of your original PA3290U 1ACA AC Adapter and select the universal PA3290U 1ACA AC Adapter or Car Charger with the same Watts or next highest Wattage.

Before purchasing an PA3290U 1ACA(http://www.udtek.com/toshiba-pa3290u1aca-ac-adapter-120w-...) AC Adapter you need to make sure make the PA3290U 1ACA AC Adapter will give you the correct voltage and suitable current output. Toshiba PA3290U 1ACA AC Adapter Use and Maintenance Correct methods of operation are: first AC adapter DC output plug into the notebook’s power jack, and then put into the AC input plug on 220V AC power outlet; and should be unloaded first when the AC input plug unplug, And then pull out the DC output plug. If the plug (unloaded) when reversing the sequence of the adapter will communicate Department unlade state, are not allowed to communicate Department adapter no-load state, for his work on the pulse, and no-load when the switch transformer windings to generate highly anti-peak voltage breakdown, such as IC, capacitor, such as ac adapter voltage-sensitive components. Although the current AC adapter has been set up its no-load protection circuit, but because of the design is required to look up to other problems, such protection circuit protective effect is very limited.

To find out the voltage & current, turn your laptop over and look for a label, sticker or writing which shows the voltage and current, it should look something like the examples below. The voltage figure will have a “V” after the number i.e 19V and the current will have a “A” or “mA”. i.e 3.15A. You can also find these shown on your original PA3290U 1ACA AC Adapter if you have it. You can work out the Wattage by multiplying the Voltage by the Amps i.e 20V X 3A = 60 Watts. There is no 60 Watt PA3290U 1ACA AC Adapter so you will need to select the next step up which is the 70 Watt PA3290U 1ACA AC Adapter. PLEASE NOTE: If the wattage requirement for your laptop is lower than the 60W or 90W output of the adapter, it will not damage your laptop, your laptop will only take the amount of power it requires. I.E. If your laptop needs 45W, then either the 60W or 90W will work OK. If your laptop needs 80W then you will need the 90W one as the 75W one will not be powerful enough.
