What does output 12V 1A mean?

What does output 12V 1A 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.

Are 12V AC adapters interchangeable?

– Yes, they are likely interchangeable even though voltage is not the same. This is because the voltage difference is within specs, and I am GUESSING you could go even higher or lower in voltage.

Can I use a 10v adapter for 12V?

No it’s not safe for the most of cases. There are two reasons. 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 12V 0.5 A adapter with a 12V 1A power rated modem?

4 Answers. You cannot use that adapter because it is outputting more voltage than the original (12v vs. The new adapter must have the same tip polarity.

Can I use 5V adapter for 12V?

In one word — no–. The battery won’t charge on 5V and it may even try to feed back into the 5V charger if for example one of the rectifier diodes is blown.
