Are AC chargers interchangeable?
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.Apr 30, 2010
Does it matter what AC adapter I use?
The short version: Voltage (V) should always be the same for both adapter and device. Polarity (plus on the left side or plus on the right side) should always be the same for both adapter and device. Current (A or mA) of the adapter should not be lower than the current of the device but may be higher.Jun 17, 2021
How do you know if a charger is compatible?
- The voltage of the adapter has to be identical. ...
- The amperage (amps) of the adapter has to be equal or greater than the device. ...
- The polarity of the adapter has to be identical.
Does it matter which AC adapter I use?
The adapter you choose must be able to supply at least the current rating of the device. Do not worry if the adapter has a higher rating as the device will only consume what it needs. Usually, a higher power adapter will be more expensive, so if you have the option just match the device's power.Nov 30, 2020
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.

How do I know what size power adapter I need?
Choosing the right adapter specs. The general rule is to match the V and equal or beat the mAh, so if you are choosing an AC adapter to make sure you check the following, The adapter output V matches the rated input V of the device. The adapter output is greater or equal to the devices rated mAh or A.Nov 30, 2020
