Can I use a power adapter with higher amps?

Can I use a power adapter with higher amps?

Can I use an AC adapter with higher amps? As long as the voltage matches that expected by the connected device, then yes, you can use an AC adapter capable of providing higher amps.

Can I use an AC adapter for DC?

Each AC/DC power adapter is specifically designed to accept a certain AC input (usually the standard output from a 120 V AC outlet in your home) and convert it to a particular DC output. The key is to match the DC output of the adapter to the DC input of your device.

How do I know what size AC adapter I need?

If you are measuring you need the diameter of the center pin for the (ID) and the inner diameter of the port (OD). ID an OD measurements for both the female and male connector must match to connect properly.

Is a switching adapter AC or DC?

A switching power supply takes an AC input, but rectifies and filters into DC first, is converted back into AC at some high switching frequency, steps down the voltage with a transformer, then is rectified and filtered into a DC output.

What is the input voltage of a DC adapter?

V = An input Voltage of 19.5V. AC or DC – DC as indicated by the symbol. mAh/A – consumes 3.34A to 4.62A of current. Once you have this key data you are ready to start looking for an adapter.

How to calculate AC to DC input amperage?

AC Amperage – Input Amperage is how much current the application draws from the AC power. This number is usually rated in Amps. If the current is rated in milliamps (mAh) you can convert it to Amps by dividing the number by 1000. For instance, our example application draws 300 milliamps, which is the same as 0.3 Amps.

What is the current rating of an AC adapter?

Also to consider is the inrush current – the manufacturer’s rating of 0.45A may include some measure of inrush current into this figure but we don’t really know. Remember also that the rating will be most valid when the input AC voltage is at 100 VAC and not when the voltage is much higher (as per your calculation).

What to look for in an AC power adapter?

The two primary ratings to match up are: voltage (V) and amperage (A). Look at the voltage and amperage ratings on your old adapter and compare them to your new adapter. Note: it’s possible to have a slight difference in voltage and amperage ratings for your device to work properly.
