What does 12V 1amp mean?
What does 12V 1amp mean?
12V 1A, means it can provide the current of 0A to 1A. while maintaining it’s 12V. After 1A, the voltage is not guarantee. For the current rating on the product, it indicate the maximum current the product will draws from it’s power supply.
How do you make a 12V 1amp power supply?
Things that you will need to make this power supply is…
- Piece of veroboard.
- Four 1N4001 diodes.
- LM7812 regulator.
- Transformer that has an output of 14v – 35v AC with an output current between 100mA to 1A, depending how much power you will need.
- 1000uF – 4700uF capacitor.
- 1uF capacitor.
- Two 100nF capacitors.
What is a 1A power adapter?
A 1A device means that, for a power supply at a certain voltage (5V for USB), the device will “ask” for 1A from the power supply. For a 1A charger, it means the electronic devices in the charger can handle 1A before they break.
How many watts is 1amp?
120 watts
That means that 1 amp = 120 watts.
What happens if you use 2A charger for 1A device?
A power supply (what you’re calling the “charger”) rated for 1A can only provide up to 1A and still operate within spec. If your phone tries to pull much more than that it will excessively load the power supply. At moderate levels of overload the result is likely only the voltage “sagging”.
