Basic Rules of electricity when selecting a power supply.

1. Check the label of the device you wish to power for the spec and Note -
The Voltage -
(Voltage Volts (V) is sometimes specified in fractions i.e 19.5V or 19.5 Volts).
The Current consumption -
(Current is specified in Amps (A) OR milliamps mA, 1000mA = 1 Amp or 1A).
The connection POLARITY -
(usually POSITIVE (+Ve) Centre Pin BUT NOT ALWAYS).
2. Check the size (and Type) of the connector -
There are many 'common' connectors from thousands available, Don't 'assume it will fit'.

Selecting a power supply -

• The OUTPUT Voltage must ALWAYS Match^{1, 2}
• The OUTPUT Current must ALWAYS be Equal OR Greater to the device³
• The Polarity must ALWAYS be the same⁴ When using voltage selectable supplies ALWAYS Select the voltage and polarity BEFORE connecting to the device.
¹ If you connect a supply with (OR Set) to a higher voltage one of the following may happen -
a) The excess VOLTAGE will probably damage your device. d) The excess VOLTAGE may cause excessive CURRENT demand, Overloading the power supply and the device or both. c) Some devices may operate perfectly until they FAIL due the excess voltage overstressing components.
² Too LOW VOLTAGE can also problems -
Too Low Voltage power supply may not operate the device correctly. Too Low Voltage on some devices with secondary internal switch mode power supplies (common in many modern devices), the the device may well operate perfectly BUT the low voltage causes More current demand, if the power supply cannot supply this current then ³ apples.
³ If you connect a supply with too low a current rating for your device several things may happen. The excess current demand will overload the rating of the power supply which could cause several different scenarios -
a) The power supply may have overload protection and cut the output, Appear as DEAD, But it's NOT. b) The power supply may still output but at lower voltage casing incorrect operation of your device. c) The power supply may Work but be over stressed and fail. c) The power supply may Work but be cut out and restart when cooler. e) The power supply may overheat and - Fail, Blow a thermal fuse, worst case Cause a FIRE!
⁴ If you connect a supply with the wrong polarity then -
There is a high probability of damaging  your device ! Best case is the device has diode input protection and the device will just appear to be dead. Rare but some devices could short circuit the supply output causing overload as in³.
5 Connector dimensions (for concentric 'Barrel' connectors with centre hole)
           e.g 5.5mm x 2.5mm  x 11mm - ( if 1 and 2 are not correct it could fit but not connect )
5.5mm - the outside diameter of the tip
common sizes are - 6.3mm, 5.5mm, 5mm, 4mm, 3.5mm, 2mm.......
2.5mm - the inside diameter of the HOLE
common sizes are - 3mm, 2.5mm, 2.1mm, 1.9mm, 1.7mm, 1.3mm.......
11mm - the length of the tip, this can vary and often not important and not specified,
