Does mA matter power supply?
The milliamp rating of a power supply is a measure of how much it can supply. The milliamp rating of a pedal is how much it uses. All that matters is supply exceeds demand. The 230 vs 220V rating probably means nothing.
Does mA matter for pedals?
A milliamp meter is useful to view the exact amperage draw of a pedal. This can prove important when configuring and assembling your pedalboard. If you are daisy-chaining pedals, the amperage ratings of each pedal are added together for one total amperage requirement.
Is it okay to use a power supply that provides slightly more voltage?
This doesn’t mean your device will consume 3.42 A when its powered with this adapter; it is only an indication of the maximum current that can be drawn through the adapter by any device that it is connected to, above which the adapter gets damaged. Any device will only draw as much current as it needs, so long as its power source can supply it.
Which is better, 500mA or 1amp power supply?
It’s the same when powering Camera’s, althought the Camera only draws 300ma from the 1000ma (1amp) supply leaveing 700ma spare it is always better to over engineer your power supplies. The 1 amp won’t damage the camera !
Can a camera draw 300mA from a 500mA power supply?
I didn’t think it would. If a camera draws 300ma on a 500ma supply, it will draw exactly the same 300ma from a 1a supply, or a 2a supply… A power supply that can provide more amperage will just have extra unused spare capacity compared to a equal one with a lower amperage..
What happens when there is too much power in a charger?
Too much power generates excess heat, which is the bane of sensitive electronics. The other important term to know is polarity. For direct currents, there is a positive pole (+) and a negative pole (-). For an adapter to work, the positive plug must mate with a negative receptacle or vice versa.
