Can I use 12V 3A for 12V 2.5 A?
Yes. The 3A is the maximum current it can supply but it works fine delivering less current. For example, when this adapter is plugged but not connected to your device the current is zero but the voltage is 12V.
Can I use A 12V 1 5A adapter with 12V 3A device?
Could I use a 12v 1,5A adapter with a 12v 3A device? – Quora. no. You can’t possibly supply enough current to power the device. It will draw 3 amps, not 1.5 amps.
What does 12vdc 2A mean?
This 12V 2A Power Adapter is a high quality power supply manufactured specifically for electronics. These are switch mode power supplies which means the output is regulated to 12V and the capable output current is much higher (2000mA). Specification: … Electric Current: Max. 2A.
Can I use 12V 5A for 12V 1A?
Yes You can 12 V 2A for 12 V 1A.
Is it OK to use a power supply with higher amps?
Can I use an AC adapter with higher amps? As long as the voltage matches that expected by the connected device, then yes, you can use an AC adapter capable of providing higher amps.
Can you use a 12V adapter for a 13v device?
’12v’ is often ‘automotive’ devices- in which case they are very tolerant of fairly wide voltage swings (basically from 10.8v to 14.4v is commonly seen in an automobile) so they will happily take a 13v supply without issue, as long as it can supply the amps- in this case device pulls 3a, supply can give 7a, so that’s …
Is it OK to use a power supply with more Amps?
4 Answers. The amperage rating on your power supply simply means that the supply can put out up to 2 amps, so as long as the voltage matches (12 volts) you could safely use a higher amp power supply for your device.Apr 20, 2019
What happens if Amps are too high?
When output current needs to be higher, it will stop acting as an ideal voltage source and will start showing imperfections such as voltage drop, overheating, current limit and so on. Voltage and resistance is all that matters.Feb 24, 2011
Can I use 3 amp instead of 1 amp?
No, amps do not have to match, but the power supply or charger must be able to supply enough amps as required by the device being powered or charged.
Will too much amperage hurt a device?
A higher voltage than a device is designed for will most likely blow up some components, but amperage is derived from how much current is actually drawn, based on the device’s resistance, so having “too much” is not a problem and will do no harm.
Can I use 12V adapter for 9V router?
You can safely use an adapter with the same output voltage, and a current (A/mA) rating equal or higher than the original. If you use one with significantly more voltage (and 12v is a full third more than 9v) then you might burn out your device.Jan 28, 2013
Can I use 12V instead of 9V?
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. … Those pedals will work perfectly fine with a 12V adapter.Mar 14, 2019
Can I use 12V instead of 5V?
The device will very likely burn out. In addition, depending on what the device is and the capacity of the 12V supply, connecting a 12V supply to a device rated 5V max could lead to a hazard – fire, explosion, etc. Mostly it will get damaged.
