Is it OK to use a power supply with more amps?

As the article states, you do want to match voltages between the power supply and device, but you can us a power supply with more amps than needed. The device will only draw as much current (Amps) as it needs at the time.

Can I use a charger with higher amperage than the original?

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.

Is high amperage dangerous?

6 to 30 mA: Painful shock, loss of muscle control. 50 to 150 mA: Extreme pain, possible severe muscle reactions, possible respiratory arrest, and even possible death. 1,000 mA to 4,300 mA: Heart ceases pumping; nerve damage and death likely. 10,000 mA (10 amps): Cardiac arrest, severe burns, and death.

Does voltage or current damage electronics?

5 Answers. A general answer is that electronic/electrical components are damaged when their electrical ratings are exceeded. Excessive current results in excessive heat which will destroy both passive and active components.

Can low amperage damage electronics?

It might not damage it directly but if the power supply fails it might damage anything that’s plug into it. So lets say you power supply is 2 amps and device on it is 4, you’ll overload the PSU. Usually it everything should just shut down but then if you power every thing on, many times, there could be damage.

Why is higher voltage more dangerous?

Higher voltage allows for the production of higher, more dangerous currents. Resistance opposes current, making high resistance a good protective measure against shock. Any voltage above 30 is generally considered to be capable of delivering dangerous shock currents.

Why are amps more dangerous than volts?

In plain English: volts (V) equals current (I) times resistance (R). So, assuming resistance is constant, voltage and current are in lockstep. Higher voltage means higher amperage, and thus higher voltage has more potential to kill. It takes only 100mA to stop your heart.

Why does high voltage damage electronics?

High voltage can cause the components to get damaged, because they were just not built to handle all that electricity. They can overheat and melt, or sometimes even spark and short circuit if wires are placed too close. , tinkered with electronics for more than 25 years.

Can low current damage electronics?

yes, Low voltage damage the home appliance. it causes motor failure in the appliance . Your home is connected to the low-voltage grid, which delivers power at a voltage of 230 volts. Voltage above or below the normal level causes damage to electronic devices.

What happens if you have too much voltage in a circuit?

A higher voltage than a device is designed for will most likely blow up some components, but amperage is derived from how much current is actually drawn, based on the device’s resistance, so having “too much” is not a problem and will do no harm. Consider a pipe bursting under too much water pressure.

What is the effect of too much voltage fluctuation on electronic devices?

Voltage- Electronic devices are designed with a little ‘headroom’ to accommodate fluctuations in voltage and manufacturer component spec variations but how high this ‘headroom’ is will vary between devices. At worst it will burn the lowest V (or heat) rated component on the board…or at least shorten it’s life, so it is best avoided completely.

What is the amperage rating of a power supply?

The amperage rating of a charger or power supply is the maximum it can supply. A device being charged will only take as much amperage as it requires. If your device needs 0.5 amps to charge, and your charger is rated at 1.0 amps, only 0.5 amps will be used.

What happens if you don’t charge your device properly?

Device works. Device may fail, may run or charge slowly, power supply may overheat, may damage the device being charged — all depending on the magnitude of the difference. The amperage provided by your charger must match or exceed what the device being charged requires. The amperage rating of a charger or power supply is the maximum it can supply.
