This is a linear adapter meaning that there is no voltage regulation, so with no load it outputs 15.6 volts and by the time it is loaded with 300 mA, the voltage is very close to 9 volts.
What is 300mA mean?
mA stands for milliamps and mAH stands for milli amp hours. So 300mA means 300 milliamperes of current is passing through the circuit whereas 600mAh means 600 milliamps of current passes in one hour. Normally electronics will be rated in mAh rather than just milliamperes.
Can I use 9V 1a for 9V 500mA?
It will work just fine. Make sure the plug fits with correct polarity.
What does 9V DC mean?
it changes the Alternating Current from your wall into 9 Volts of Direct Current.
What is adapter 9V?

What does 100ma mean?
Meeting a Device’s Power Needs
For example, an alarm clock might require 100 milliamps to function, so it would need a 100 milliamps, or 100 mA, power cord or adapter. A cell phone might require 1,000 milliamps, so it would need cord capable of producing 1,000 milliamps, or 1,000 mA.
How many mA is 0.3 a?
amps to milliamps metric conversion table
| amps to milliamps metric conversion table | ||
|---|---|---|
| 0.01 A = 10 mA | 0.1 A = 100 mA | 851 A = 851000 mA |
| 0.02 A = 20 mA | 0.2 A = 200 mA | 852 A = 852000 mA |
| 0.03 A = 30 mA | 0.3 A = 300 mA | 853 A = 853000 mA |
| 0.04 A = 40 mA | 0.4 A = 400 mA | 854 A = 854000 mA |
Can I use 200mA instead of 300mA?
In principle yes of course. The 300mA rating is the maximum the device can safely deliver, not what it automatically outputs. As long as voltage is the same and ampere is higher, you can substitute. So in this case you can replace 200mA adapter by 300mA.
What’s the difference between 100mA and 500mA?
The pedals will draw as much amperage as they need, up to the stated limit. if your pedal needs only 100ma, then that is what it will pull, even if plugged into a 500ma outlet. Higher AMPS = OK, higher volts = BAD.
Can I use a 12V power supply on a 9V guitar pedal?
If you have a 12V adapter, you might wonder whether you can use it to power your 9V guitar pedals. In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it.
What is 9V center negative?
A center-negative plug will have the negative voltage on the center conductor and the positive voltage on the sleeve (outside) conductor. A 9V DC center-negative power supply is the de facto standard for pedals.
Can I use a 20V charger on a 19.5 V laptop?
Technically yes, but the prudent thing to do is find an OEM charger. Sure, 19.5 is very close to 20V and the 19.5V power supply can easily handle the 4.5A max of the lap top. Normally any device has a voltage range, not a tight fixed voltage requirement.
What does Center positive mean?
Centre Positive.
Indicates that the centre (tip) of the output plug is Positive (+) and the barrel of the output plug is Negative (-).
Can I use a 9V adapter for 9.5 V?
Sure. You actually need a little more than the rated battery voltage to charge a battery. Half a volt out of 9 is only about 5% which should be about right. Just check the charge current to make sure it is not more than recommended by the manufacturer, or absent a recommendation, it should not make the battery hot.
How many watts is 9V 2A?
9 Volt 2A Power Adapter Supply 9V Power Supply 2A Transformer 9V Power Supply 18 Watt (2 Amp) LED Power Supply 2.5mm X 5.5mm Plug Wall Adapter. Learn more about free returns.
What is 1000mA?
One milliampere is equal to 1/1,000 of an ampere, which is the electrical current equal to the flow of one coulomb per second. The milliampere is a multiple of the ampere, which is the SI base unit for electric current.
Are milliAmps important?
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.
How do you read 50 milliAmps on A multimeter?
The current flows through the multimeter, which displays the current. Ensure that the current is in the range of mA expected and then lower the setting of your multimeter to the next-highest option – for a 0.05 A or 50 mA current, choose 200 mA – to get a precise reading in milliamps.
How do you convert MH to Henry?
To convert a millihenry measurement to a henry measurement, divide the electrical inductance by the conversion ratio. The electrical inductance in henries is equal to the millihenries divided by 1,000.
How many milliamps does .0012 amps represent?
0012 amps or 1.2 milliamps.
How do you convert Microfarad to Farad?
To convert a microfarad measurement to a farad measurement, divide the capacitance by the conversion ratio. The capacitance in farads is equal to the microfarads divided by 1,000,000.
