Are all AC power adapters the same?

– Yes, they are likely interchangeable even though voltage is not the same. This is because the voltage difference is within specs, and I am GUESSING you could go even higher or lower in voltage.

How do I choose an AC adapter replacement?

When considering how to choose an AC adapter, avoid picking one that delivers a lower current than required by the device. Even when both the adapter and the device have the same voltage rating, the device will attempt to draw more current than the AC adapter can manage. This can cause the adapter to overheat.

Are power supply plugs universal?

If so, yes. Any cable will work. A 1,000W power supply (80\% efficient) will pull about 10 amps at full load. That’s well within the specs of any of those cables.

Can I use any power adapter?

You can safely use an adapter with the same output voltage, and a current (A/mA) rating equal or higher than the original.

Are AC adapters universal?

As long as the voltage is the same on the adapter and on the device (also, I have 9V DC and 9V AC adapters, do not mix these up) and be sure the current required is less than the amount that the adapter can source otherwise you risk overloading the power supply.

How do I tell what size my power adapter is?

Typical low voltage adapter sizes. A 5 mm OD x 2 mm ID says the outer diameter is 5mm and the inner is 2mm. If you go into a shop you can compare and test the connector size, or if you are technically minded you can measure the size of the port and pin yourself.

How do I know what size power adapter I need?

If you go into a shop you can compare and test the connector size, or if you are technically minded you can measure the size of the port and pin yourself. If you are measuring you need the diameter of the center pin for the (ID) and the inner diameter of the port (OD).

Can I use 45w charger instead of 65w?

You may use 45w charger instead of 65w because they have same tip but might take longer time for device to be full charge . Yes. Wattage is a measurement of how much power a supply CAN generate, or how much your device DOES consume.

Can you mix and match AC adapters?
