Are all 9V AC adapters the same?
As long as the voltage is the same on the adapter and on the device (also, I have 9V DC and 9V AC adapters, do not mix these up) and be sure the current required is less than the amount that the adapter can source otherwise you risk overloading the power supply.
Does 1000mA equal 1A?
There is no difference. Mili is a subunit which totals 1/1000 of the main unit, thus 1000 mA = 1A.
What does 9V 300mA mean?
9V Power Adapter, 300mA Nameplate Rating: Input: 120V AC 60Hz, 6W Output: 9V DC, 300mA. 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 1000mA mean?
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. A milliampere is sometimes also referred to as a milliamp. Milliamperes can be abbreviated as mA; for example, 1 milliampere can be written as 1 mA.
Will any 9V adapter work?
any 9v with the correct polarity (- inside +on the outside i think) that supplies enough amperes (250 milliamperes minimumi think) will work fine. As long as the voltage matches up, 9v DC pedal with a 9v DC power supply, you will be fine.
Can I use 2000mA instead of 1000mA?
Using a 2000 mA charger for an appliance using a 1000 mA is perfectly fine. CAUTION: make sure the charger emits the correct voltage, using a 2000mA/24V charger on a 1000mA/12V appliance will most likely damage the circuit.
Is it safe to mix 9V and 9V power adapters?
As long as the voltage is the same on the adapter and on the device (also, I have 9V DC and 9V AC adapters, do not mix these up) and be sure the current required is less than the amount that the adapter can source otherwise you risk overloading the power supply.
What voltage should I choose for my power adapter?
It is important to use the correct volts when choosing the adapter as a device can only run on the rated voltage. The most common are 18V, 12V, 9V, 6V, 5V and 3V.
Is it safe to charge a device with a 12V adapter?
There’s no risk in selecting an adapter that is able to deliver a current of 1 Amps (1000 mA) at 12 volts. The device is not harmed by this. If the current is not enough, voltage might collapse causing slow charging of battery devices or inoperatibility of the device.
How many amps can a 12 volt adapter handle?
The power formula P (watts) = I (ampere) x V (volts) shows you that if for example the needed power is 5 watts and the adapter delivers 12 volts, the adapter must be able to supply a current of at least 0,41 Amps (or 410 mA). There’s no risk in selecting an adapter that is able to deliver a current of 1 Amps (1000 mA) at 12 volts.
