Is it ok to use a 4.5v 800mA AC adapter for a device when the original adapter is supposed to be 4.5V 500mA - will it damage the device?

Yes. As long as the voltage is the same which it is. The 800mA is the capacity that the transformer can produce safely without going into an overload state. Your original adapter was rated at 500mA which means that what ever device was plugged into it draws less that 500mA. You might notice that the new adapter is slightly physically larger. So you are safe to use the new adapter with the higher rating.


Can a 12V 800MA adapter be used in place of a 12V 500 Ma adapter?

Yes


Can you use a 9V 500mA for a 9V 800mA?

Using an undersized power supply is not a good idea. The device drawing 850 mA being connected to a 800 mA source will work but the adapter will get warm to hot over a period of time. This overloading of the power supply will eventually destroy the adapter.


What adapter has more power the 9v 600ma or the 9v 800ma?

The capacity of the 800 mA adapter is 200 mA larger than the 600 mA adapter.


Can you use a universal ac adaptor set at 9v 400mA for a portable radio set at 9v 800mA?

No. Your portable radio needs 800mA to operate. Your adapter can only produce 400mA. If you make the connection the adapter will rapidly heat up and probably burn out.


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 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 5cV DC 800mA adapter in place of 6 V DC 300 mA adapter?

Worry about the voltage type and sign more than the mA. If the specs are right on target, you probably could. If not, not.


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.


Can you use an AC adaptor - 6v dc 1300 ma to replace AC adaptor - 6 v DC 800 ma?

Yes you can. All the 1300 mA rating means is that adaptor can supply devices up to 1300 mA. The old adaptor's limit was 800 mA. The new adapter has 500 mA more in reserve if it is ever needed.


Can you use 250 volt 1A for 230 volt 800mA?

no


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.
