What should a power supply voltage be?
With that in mind, voltage is the essential factor and again should be the same or within a tolerance of 1 volt. A full guide on the key details of any power supply, charger or adapter including voltage, amperage and wattage.
What does amps mean on a power supply?
In a nutshell, the Amps rating on a power supply, charger or adapter explains the maximum amount of current that it can safely provide in an hour. Any amperage of charger rated above what's required for your device is safe to use with your device, providing the PSU voltage is the same as the input voltage or within a tolerance of 1 volt.
How do I choose a power supply?
Power supplies go by a lot of different names, you can call them Wall Warts, AC Adapters, Plugpacks, or AC/DC Converters, whatever takes your fancy. Below are my three generalised golden rules for selecting a power supply for any maker electrical project. Your Power Supply Voltage Output must be the same as your Hardware Demands.
What is the current rating of a power supply?
The current rating of a supply is what it can deliver, not what it will always force thru the load somehow. In that sense, unlike with voltage, the current rating of a power supply must be at least what the device wants but there is no harm in it being higher. A 9 volt 5 amp supply is a superset of a 9 volt 2 amp supply, for example.
What is the minimum load requirement for a power supply?
Some power supplies, generally older switchers, have a minimum load requirement. This is usually 10% of full rated output current. For example, a 12 volt 2 amp supply with a minimum load requirement of 10% isn't guaranteed to work right unless you load it with at least 200 mA.
What is the Max Watt output of a power supply?
From our provided information above and Ohms Law, you will be able to figure out that the Max Watt Output of this Powersupply is 24 Watts. There is another way to gain this information too. Looking at your power supply it will have a specification sticker that looks a lot like the image below.

amperage
Please pass this on. Dear cousin, The power supply is converting power from one voltage to another. The relationship between power, voltage and current is given by the formula $ P = VI $, where P is power in watts (W), V is voltage (V) and I is current (amperes, amps or A).. If we step down the voltage from 230 V to 9 V, a factor of about 25, then we would expect the …
