What happens if power supply voltage is too low?

If the voltage is too low, the amperage increases, which may result in the components melting down or causing the appliance to malfunction. If the voltage is too high, this will cause appliances to run ‘too fast and too high’ which will shorten their service life.

Can I use 12V adapter for 6V device?

It depends on what the device is. If the device has its own internal switching regulator, the voltage probably won’t be a problem, but since the 12V power supply has a lower maximum power (12V * 0.35A = 4.2W, and 6V * 1A = 6W), it may draw too much power and the power supply will be damaged.

Can low voltage damage my computer?

Low voltage can definitely ruin the computer (usually only ruin the PSU though), if the voltage drops below the voltage ratings of the PSU (depending on model either within ~20\% of it’s intended voltage or between 85 and 250V for a very good one).

Can I charge a 5V battery with a 6V charger?

To charge a 6 V lead acid battery requires 6.9 to 7.1 V. 5 V will just not work.

Why is my power supply rated for the same voltage?

Devices operate on voltage. Your replacement power supply MUST be rated for the same voltage. Going too low can cause the device to not work (or worse, not work some of the time!) whereas going too high on the voltage could cause overheating or damage to electrical components.

What will happen if I connect a 5V to a 12V?

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. In your opinion, what would be the average initial startup cost for product development?

What will happen if I use a 12V power supply?

With 12V your device will draw double the current and gets heated up because all current limiting values of your device are calculated for 5V source. Can a human carry 200 Kg on his shoulders, no, average human is designed to carry around 25 Kg only. The device will very likely burn out.

Is it safe to change power adapter to 9V DC 1A?

Is it safe to change this to 9V DC 1A? Or perhaps to 9V DC 2A? No, it’s not safe to assume that either of those will work. In fact, even if you did find a “8V 2.6A” power adapter it might still not be safe unless you also know whether the old power adapter was regulated or not.
