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.
Can I use a 5V 2A charger with a 5V 1A device?
What happens when use a 5v 2a rated power adapter for a device rated 5v 1a? The adapter works perfectly if the rated value is stated on it. If you use 5V 2A for the use of 5V 1A, it will work. There will be a dip in the output voltage if you operate a load of 2.5 A rated value.
Does the AMP matter on a power supply?
It doesn’t matter if the power supply / charger can provide more current then the device requires. Providing less current will prevent charging or slow it down the same as a poorly designed charger can also prevent charging or slow it down.
Can I use 12V 2A for 12V 1.5 A?
You can use a 12V supply with a higher current rating, but not a lower one. The device will only draw the current it wants, but the supply has to able to put out the maximum current the device wants. Since that may be in the 1-1.5 Amp range, the 1A supply is not good enough.
Can I use a 12V power supply on a 19v?
A 12V adapter is unlikely to damage the components, but it is possible depending on the design and that’s why I mentioned it. The likelihood is probably vey tiny though so you can probably ignore that bit.
Will too much amperage hurt a device?
Can too many amps damage a device? … If an incorrect voltage is used — say a higher voltage than the device is rated to accept — then yes, too many amps may be drawn and the device can be damaged. This is why it’s critical to use the correct voltage.
What’s the difference between 5V 1A and 5V 2A?
While we know that 5V 2A chargers can charge a smartphone faster than a 5V 1A charger. By simple maths, 5V 2A means 10W – that means double the speed of a 5V 1A charger, right?
Is it OK to use a lower amp power supply?
We recommend higher amperage to ensure cooler power supply and optimal charge time. If you get a charger with amperage less than your original power supply, you risk overheating your charger, burning it and in many case your device will stop functioning and/or charging.
How do I reduce the amps on my power supply?
In order to lower the amperage of an electrical circuit, you must either lower the circuit’s voltage or increase its resistance. Lowering amperage is done by applying Ohm’s law, given by the formula I = V/R, where I is the circuit’s total current in amperes, V is the voltage and R is the resistance.
Can I use a 15V power supply on a 12V?
Onus : Assuming the polarity is correct, plugging in a 12V input to a device requiring 15V won’t do any damage, however if you undervolt an amplifier, you may get clipping or other distortion.
What does 12V 1.5A mean?
The device 12 V 1.5 A, means that it wants a fixed 12 V and at most, will use 1.5 Amps current flow when running with 12 V. Since 1.5 is less than 3 and 12 = 12 then you should be OK.
Is higher or lower amps better?
A higher voltage system is more efficient than a lower voltage since it experiences less energy loss from resistance given the same amount of power draw. … You get the same exact voltage—but with 80 amps of current. That’s 80% more energy!
Can I use A 24v power supply on A 12V?
Yes, plugging a 12 volt device into a 24 volt supply could very well destroy the 12 volt device. I had a 12 volt VoIP adapter that I connected to a 12 volt battery and smoked it. I then ran voltage tests on the battery and discovered it had a voltage of about 13.8 volts because of the constantly connected charger.
Can I use a 19V charger on a 19.5 V laptop?
The 19.5V vs 19V will not matter (it is a small enough difference); as long as the current rating on the charger is at least as much as the current rating printed on the laptop it will be fine. The chargers are “generic”; the same model is used for various laptops even with the OEM chargers.
Can you charge laptop with 12V?
However, to answer your Question: yes you can. There’s any number of 12v laptop chargers on eBay for a few quid. They are in effect a mini inverter converting the 12v input to an output of typically between 15v and 24v.
Can I use a 19V charger for a 20v laptop?
20v can be used for 19v provided that the current score of 20v is equal or higher, but only temporarily. The best to charge the battery and then disconnect and run the laptop, notebook etc on your own batteries to ensure a correct entry into the circuit. Runng 20v for 19v directly is not recommended.
