No, the mA rating of adapters is the maximum amount of load that can be drawn from the adapter. 1 amp is equal to 1000 mA. By replacing a 800 mA adapter instead of using a 1000 mA adapter is limiting the connected devices load by 200 mA. If the connected device draws 800 mA's or less then the adapter will work.

∙ 11y agoIt depends on the requirements of the device being powered. If the device only requires 1200mA then yes it can be used. If it truly requires 2 amps than it will not function properly and could damage the power adapter. 1200mA is 1.2 amps, this power adapter actually has less power available than the 2 amp version.

∙ 15y agoNo. You can always increase the mila-amps (mA) but not lower them. Also if the polarity of the plug isn't correct, you can cause permanent damage to your equipment.

∙ 11y agoIt will be fine the device will only draw what it needs
Wiki User
∙ 14y agoYes, if the connector is the same then the higher current adaptor should be fine.
Wiki User
∙ 13y agoYes, but be sure the connector polarity is the same (or cut and resolder to correct that). Also, not all adapters are AC/DC, some are AC/AC (9vac vs 9vdc).
Wiki User
∙ 11y agoYes, as long as the capacity of the adapter is larger than what the device needs to operate it will work nicely.
Wiki User
∙ 13y agoNo, the power adapter has to match the power requirement.
Wiki User
∙ 11y agoYes, the supply of 500 mA will supply a 300 mA device very nicely.

What does polarity mean on a universal ac dc power adapter?
According to google if you have an automatic universal adapter, that adapter will automaticly find and adapt itself , the polarity ,voltage,amper , so that means an adapter can adapt polarities as well as voltage and current. A manual universal adapter on the other hand you have to adapt the polarity manually on the adapter itself , by checking what the device you wanna power has positive or negative, most electronic devices presently use positive . Check and see what voltage , amper and polarity a device needs. Positive : +--o)--Minus , Negative : Minus--o)--+ Or Positive: Minus--(o---+ , Negative : +---(o---Minus And adjust manually to what is required.
Will a 6V adapter work on a 9V device?
Depending on what we're talking about here, most devices will tolerate +/-15%, or in your case, 7.65v to 10.35v. A 6V power supply will only give the device 66% of the power it's rated for (not enough). Even if you could find an adapter that would fall within the 15% tolerance, it's not a good idea to try it. A multi-voltage adapter can usually be purchased for cheap at your local RadioShack or if you're feeling lucky, you might be able to find one at any place that recycles electronics (Goodwill or any local recyclers).
Can the Alesis Micron run on battery power?
Not normally. It takes a 9 volt AC adapter. If you were to get something to replace that that ran on batteries, it could.
How do you hook up a digitech whammy to voodoo lab pedal power 2?
You can't. You have to use the pedal's AC adapter or a Voodoo Lab Pedal Power AC. Pedal Power 2 is a DC unit; the Whammy is an AC unit.
Can you run a device that requires 700mA with a power supply that generates 1.8A?
A power supply that produces 1.8 amps is the same as saying 1800 mA. What has to be taken into account here is if the voltages are the same. If the device that uses 700 mA has a specific voltage to operate on can the power supply provide the same voltage. Another factor to look at is , both the device and the power supply have to match their AC or DC requirements. One can not be AC and the other DC or vice versa.
Will 9v 300mA power adapter work with a 9v 700mA device?
No, the adapter's power output has to be equal to or greater that the current draw of the device.
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 power a 9v 700ma device with a 9v 300ma adaptor?
No. The device will try to draw 700 milliamps which will overload the 300 milliamp adapter most likely causing it to burn out and possibly catch fire.
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 12VCD 500mA instead of a7.5V 800mA AC power adapter?
Yes you can. But it may damage your computers power supply.
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 you safely use a universal AC adaptor set for 9V 300mA for a game that requires a 9V 700mA?
No, a power adapter must supply the same voltage, same polarity, and at least as much current as the load requires. Your adapter can only supply 300mA, which is less than the 700mA required by the load.Your game probably will not turn on and the power adapter may be damaged.
Will 6v 300mA power adaptor work with a 6v 500mA device?
Most probably you are using a AC (117V or 220V) to DC 6V converter adapter. If yes, then the answer is no, you cannot use a lower current rating for a device that draws more current. If you plug in a device that needs DC 6V 500 mA to an adapter that can only supply DC 6V 300mA, then the adapter could start sending higher than 6 volts current which may damage your equipment or overheat the adapter. If you are using a higher mA rating adapter, then it's okay. For more technical details, see: http://www.jaycar.com.au/images_uploaded/plugpack.pdf
Can you use a 9v 600Ma adaptor to power a 9v 300Ma appliance?
I think you mean to ask if one can use a 9v 600mA adapter to power a 9v 300mA appliance. Yes, you can do that. A 9v 600mA adapter will deliver 9v at up to 600mA. A mA is one milli amp, or one thousandth of an amp. 300mA is 300 thousandth of an amp, 300/1000 or 0.3 amps. 600mA is 600 thousandth of an amp, 600/1000 or 0.6 amps, and is twice the current of 300mA.
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.
Can you run a 4.3v device with a 5v power adapter?
Yes, you can run a 4.3v device with a 5v power adapter as long as the amperage of the 4.3 volt device is under the amperage capacity of the 5 volt adapter.
What would happen if you used a 19V 3.16Amp power adapter on something that called for a 12V 3Amp power adapter power supply?
You would overload and damage the device and/or the adapter.
