What happens if I use a 12V adapter on a 10v device?
Since newer adapter has more terminal voltage therefore device is liable to draw more current and bad thing is that newer adapter is ready to provide more current. …
Can I use a lower amperage power supply?
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. In practical terms, that means the amperage rating of a power supply or charger must match or exceed that required by the device it is connected to.
Can I use 12v adapter for 19V?
19V is generally going to fry any device that was designed to run at 12V (especially consumer products). And while it’s not very likely it might also catch fire. For a AC adapter to work you will need one with the exact voltage (12V) and an equal or higher current rating (1.5A or more).
Can I use 12v adapter for 16v?
Your 12v adapter would only be able to raise the battery voltage to 12v, but to charge a car battery fully you would need to raise the voltage to 13.8v. The 16v adapter would raise the voltage too high and could cause damage.
Can a 12V power adapter be used on a 1.5A device?
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. Adapter because your load device has a resistance rating that draws 1.5 amps.
Can a 12V supply be used with a 1A supply?
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 a 1.5A power supply be replaced with a 1A supply?
No, a 1A power supply isn’t a replacement for a 1.5A power supply. It might work if the disk actually takes less than 1A and the power supply was sized with some margin. However, these high volume items are are usually trimmed to the bone, so probably not. You can use a 12V supply with a higher current rating, but not a lower one.
What do you need to know about 12V DC power supply?
The only information you need to have in order to find the correct power supply for your device is the Voltage / Volts (V) and Amperage / Amps (A). Voltage has to be an exact match. A 12V DC device needs a 12V DC adapter.
