# Can I use A higher voltage power adapter?

## Can I use A higher voltage power adapter?

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 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 happens if I use A higher voltage adapter?

Voltage too high – If the adapter has a higher voltage, but the current is the same, then the device will likely shut itself off when it detects an overvoltage. The device could power on and draw more current from the adapter than it’s designed for. This could cause the adapter to overheat or fail.

Can I use A higher amp charger on A lower amp device?

Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.

Can I use a 5.2 V charger instead of 5V?

The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance. Solder in the USB connector and you can plug in any iPad, iPhone or iPod for 1000mA charge rate.

## Can I use a 5V adapter for 12v?

So now you know you can get 12V DC from 5V DC but as you increased the voltage, the output current must reduce to respect conservation principle. So in reality you can extract very limited amount of power from your converter.

### 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 I use a 5V adapter for 12V?

Can too many amps damage 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.

Can I use 12v adapter for 5V?

5 Answers. Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.

## How do you convert 5V to 12V?

Step up DC-DC converter is based on LM2577-ADJ IC, this project provides 12V output using 5V input, maximum output load 800mA.
