Can I charge with different amperage?
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.
What happens if you charge something with the wrong voltage?
Using a charger with the wrong voltage rating can potentially damage your laptop. This is typically caused by too high voltage. But using a charger with too high current won’t damage your laptop. Using a charger with too low current rating might fry the power supply, but not the laptop.
Is it okay to use a power supply that provides slightly more voltage and amperage than what’s rated?
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.
What happens if the amperage is too high?
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 a charger have the same voltage as the device?
Amperage The amperage provided by your charger must match or exceed what the device being charged requires. The amperage rating is the maximum amount of power it can supply. A device being charged will only take as much amperage as it requires.
Is it okay to use a lower amperage Charger?
Use a genuine spare part for preference, if you can’t get the genuine part one with the right voltage, current, barrel jack and polarity. It is possible to use a lower amperage charger to run and operate your laptop, but may not able to simultaneously charge the battery..
What is the difference between amperage and voltage?
Amperage is the strength of an electric current often used to measure charging. In fact, amperage is the difference between a lightning quick full charge and an all-day trickle. Amperage is the defining factor of how quickly your device will charge. Voltage, on the other hand, is the unit of current.
Which is more dangerous an electrical shock or amperage?
An electrical current at 1,000 volts is no more deadly than a current at 100 volts, but tiny changes in amperage can mean the difference between life and death when a person receives an electrical shock. Although the physics are complicated, some experts use an analogy of a flowing river to explain the principles of electricity.
