Is it okay to use a power supply with higher amps?

Thus, as long as you replace your power supply with one capable of providing as much or more amps than the previous, you’ll be fine.

Can I use a charger with more output amperage than the device needs?

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 supply too much amperage?

If the power supply can supply more than 2.1Amps this doesn’t matter as the product will only take 2.1Amps. If the power supply can only supply 1 Amp in this case then either the product will fail to work/charge or charge slowly as it can’t get enough current (or power) to charge the battery.

Can I use a 12V 0.5 A adapter with a 12V 1a power rated modem?

Yes. An adapter will need to be providing the same voltage as the television.

Can I use a power supply with lower amps?

We recommend higher amperage to ensure cooler power supply and optimal charge time. If you get a charger with amperage less than your original power supply, you risk overheating your charger, burning it and in many case your device will stop functioning and/or charging.

Is it safe to use a higher amp power supply?

If the power source has more than the required current, it should work quite nicely, It won’t stress either the power source or the device being powered. Yes, it is safe to use a greater amperage. The device will only draw what it needs.

Can a power supply supply more current than the rated voltage?

The power supply will normally supply the rated voltage up to the rated current. Just because a 12v power supply can supply 10 amps, doesn’t mean that the power supply will force 10 amps through the circuit. It is, generally, not okay to supply a component with more current than its rated for.

What does amp rating mean on a power supply?

The amperage rating on your power supply simply means that the supply can put out up to 2 amps, so as long as the voltage matches (12 volts) you could safely use a higher amp power supply for your device.

How many amps can a 12V power supply supply?

A power supply has a voltage and current rating (amongst other ratings). The power supply will normally supply the rated voltage up to the rated current. Just because a 12v power supply can supply 10 amps, doesn’t mean that the power supply will force 10 amps through the circuit.
