Are all DC 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.

What is the difference between an AC adapter and a DC adapter?

A DC adaptor differs from an AC adaptor in that the DC adaptor converts AC electricity into DC electricity. For example, a 12 V DC adaptor sold in the United States will convert 120 V AC at 60 Hz into 12 V DC. Like its AC counterpart, a DC adaptor is also rated for maximum power output in watts.

Can I use 1000ma instead of 500ma?

If the device requests 500ma and the power supply can handle up to 1000ma, it’s fine. The device will only draw what it needs and no more. If the device demands more ma than the power supply can deliver, it will force the power supply to deliver it anyway thus frying the power supply.

What does a DC adapter do?

An AC-DC power supply or adapter is an electrical device that obtains electricity from a grid-based power supply and converts it into a different current, frequency, and voltage. AC-DC power supplies are necessary to provide the right power that an electrical component needs.

Can you use an AC adapter on a DC device?

In many instances, yes. The central function of AC adapters is the conversion of mains current from AC to DC for electronic devices with a rechargeable battery.

Can I use 12V adapter for 19v?

A 12V adapter is unlikely to damage the components, but it is possible depending on the design and that’s why I mentioned it. The likelihood is probably vey tiny though so you can probably ignore that bit.

What happens if the amps are 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.

How big is a 12V 500mA AC adapter?

. . UpBright 12 Volt Power Supply 1 Amp Standard (12V 1A DC) 12W Replacement AC Adapter 12VDC 0.5A 1.0A 500mA 1000mA Power Cord Cable Battery Charger w/ 5.5mm (OD) x 2.1mm / 2.5mm (ID) Center Positive Tip . . .

What’s the difference between DC and DC power adapters?

Likewise, each electronic device is specifically designed to accept a certain DC input. The key is to match the DC output of the adapter to the DC input of your device. Determining the outputs and inputs of your adapters and devices is the hard part. Power adapters are a bit like canned food.

Is it better to use a higher power adapter?

Usually, a higher power adapter will be more expensive, so if you have the option just match the device’s power. Your device is unlikely to operate if you have an adapter with a lower A or mAh output then the device, and if it does operate the adapter is likely to get very hot and could be dangerous.

What kind of AC adapter do I need for battery charger?

Basically, it converts your mains power AC 110-240V AC into a smaller usually DC voltage that your small device needs to operate. Often these are required for charging or powering battery operated devices.
