Can you use a 12VCD 500mA instead of a7.5V 800mA AC power adapter?
Yes you can. But it may damage your computers power supply.
Regulated power supply?

What is power supply?
If it is a computer power supply it is the box that gives the computer its power from the outlet.
What is the value of ripple in the ideal dc power supply?
In an ideal DC power supply, there is no ripple.
What the conclusion that can take in multiple dc power supply?
conclusion of dc power supply 9V
What voltage is power supply for an AKAI S20?
Output is: DC10V - 800mA - Center Positive
Can you use a 12VCD 500mA instead of a7.5V 800mA AC power adapter?
Yes you can. But it may damage your computers power supply.
Say the power consumption of my 12v devise is 80 mA or less and the instructions say use a 12v 300 mA power supply and I use a 12v 800mA OK or not?
Using a 12V 800mA power supply for a device that requires 80mA or less is okay. The device will only draw the current it needs, so having a power supply with higher current capability will not cause any harm. It's important that the voltage matches, but the current rating of the power supply can be higher than what the device requires.
Can a12v 800ma adapt be used in place of a 12v 500ma adapt?
For power supplies, if the voltage is the same, the rated amperage is equal to or greater than the requirements of the device, and the plug fits, the supply is safe to use.
Can you use a 9V 850MA power supply on a unit requiring 9V 2100MA?
No. A device that requires 2100 ma or 2.1 amps can not receive enough amperage from a power supply that will only deliver 850 ma or .85 amps.
What type of power supply does a sportcraft unicorn 78057 dartboard use?
Sportcraft / Unicorn Part# 79534 "AC Adapter - 9V/800MA" 9 Volt, 800MA +/- AC adapter See attached image of official parts re-order form and manual.
Can dc 5V 800mA works with 5v 2.5A?
When sizing power sources, you must match voltage (which you have done) and make sure the supply can supply enough current to the electronics. If your supply is the 800mA, and the equipment using this needs 2500mA, then the power supply is undersized. If the supply is the 2500mA and the user is 800mA, then your power supply is oversized, and will work just fine.
What does 9 volt 800mA means?
A 9 volt 800mA rating indicates the power output of the device, with 9 volts being the voltage supplied and 800mA (milliampere) being the current capacity. This means the device can provide a continuous current of 800mA at a voltage of 9 volts.
Is ATX power supply can be used in place of AT power supply?
No because they have different connectors.
Can a 9v 800ma adapter be used on a 9v 200ma device?
Yes. There's a subtle difference in the meaning of the "--- ma" labels on the two units:-- On the "device" ... the unit that uses power ... the "200ma" is the current it useswhile it's operating.-- On the "adapter" ... the unit that supplies power ... the "800ma" is the maximumcurrent that it's able to supply. Anything less than that is easy.So your adapter is OK to operate your device. In fact, with suitable wiring and a bit ofcooling, it could nominally operate 4 of them at the same time.
Is there any way to control the voltage output on usb?
The output voltage available at a USB port is controlled by the regulator in the computers power supply. It is fixed, you can not change or control it. The maximum current which should be drawn from a USB2 port is 500mA, from a USB3 port it can (I believe) be up to 850mA.
Can you use a 800ma on a router that calls for 1000ma?
It is usually safe to use lower amperage on appliances, however, unlikely that it will have enough power to operate let alone power on.
