What happens if you get the wrong power supply?
If you’re lucky, nothing will happen, and no damage will occur. If you are unlucky, your device will be damaged. There’s a middle ground, too. Some laptops and other devices include polarity protection, which is essentially a fuse that burns out if you use the wrong polarity.
Can using the wrong power adapter?
You can damage a laptop using the wrong power supply, but that is unlikely. However, many laptops from the last decade standardized on 19.4V. USB-C laptops also tend to be powered at 20V. In short, your power adapters tend to output the same voltage despite using different tips.
Can I use a 24V power supply on a 12V?
The 24V supply can be used but you need to add a series resister to drop the voltage by 12v.
Can I use a power supply with higher voltage?
Higher current (A) is okay because the device won’t use as much, but higher voltage (V) is going to “fry” it. Conversely, lower voltage is unlikely to cause damage since the device simply won’t have enough power, but lower current can cause trouble because the power supply cannot provide enough.
Can I use a 19V power supply on a 12V?
19V in general is too high for a 12V device. I wouldn’t recommend going any higher than 14–15V. Even if your device works for some time, it will likely get damaged after some time (it could be seconds, minutes, hours, days…).
What happens if you use a higher voltage power supply?
If the current is the same but the voltage is too high, the device will shut itself off. It can run hotter than normal if it doesn’t, which can shorten the life of the device or cause immediate damage.
What happens if you use 24V instead of 12V?
No. Or almost certainly not. Any electronic device won’t work very far outside its design limits, and might be damaged – at least if the voltage is too large. A 24V device might work between 19V and 33V; a professionally-made device will have a published working voltage range.
Can I use a 16V power supply on a 12V?
You can use it in emergency but it is not for regular use because when we say 12V 0.5 A and 12V 1A, it’s not just the same … the 12V 1A is basically and actually a higher voltage level over 12V .
What happens when you plug in the wrong power adapter?
I later found the correct cable and when i put it in the inner light was still blinking and the mybook was not coming on at all, it was completely silent and the fan was not even spinning. The green power light on the cable is also blinking when it is plugged into the mybook but it is steady when it is taken out.
What kind of power supply do I need for external drive?
You can use a power supply capable of 50000 amps if you like. It’s only used if needed. It is the voltage that is of importance. You can generally get away with a miniscule amount of volts higher than what the device requires but too high of volts is what will burn something out. Thx for the replies guys.
Is the Green Power Light on my MyBook blinking?
The green power light on the cable is also blinking when it is plugged into the mybook but it is steady when it is taken out. Is there anything i can do to salvage this or is all my data completely gone. Can anyone please help.
