What else can I help you with?
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 Charge 9v with 12v dc power?
No, not possible. The charger has to go to higher volts than the battery being charged.
Will a 15DC 1000mA power supply work on a device needing 15DC 1500mA power supply?
Your question is confusing, but if you are asking whether you can use a 9V/250 mA adapter to supply a load device rated at 5 V/1000 mA, then the rule is quite straightforward. The adapter's rated output voltage must match that of the intended load, but its rated current must exceed that of the load. So in your example, you cannot use the adapter with the intended load.
Can you add batteries of different voltages to a series for instance you have 5 AA batteries in a series can you solder a 9V to increase the output voltage without destroying the circuit?
Yes, but the 9V can't deliver as much current as the AA can. Internally a standard 9V contains 6 AAAA batteries. It would be best to use all AAAA cells or all AA cells, depending on current requirement of the load.
What is the current of a 9 volt battery with a resistance of A ohms?
Current I = V/R V = 9V R = 100ohm I = 9V/100ohm = 90mA
Can 9V 1A adapter be used for 12V 1A speakers?
No. If it works at all, it will be underpowered, and possibly damage the speakers. To power 12V speakers, you have to have an adapter with EXACTLY 12V (no more, no less), and at least 1A. You could hook up a 12V 4A adapter if you wanted to, your speakers would just only draw 1A of power. Make sure you use a 12V adapter though!!
Can you use 9V 500mA adapter for 9v 700mA 6.3VA device?
yes, if the other adapter is a va
Can you use a 9v 300mA adapter on a 9v 200mA device?
No. The adaptor will overheat.
Can you use a 9V 600mA adapter on a 9V 400ma scanner?
You can use any 9v adapter as long as the output amperage is rated higher than the amperage rating of your appliance so yes a 600ma adapter can be used to power a 500ma or 400ma appliance
Can I use a dc 9V 350mA ac adapter in place of 9V 210mA adapter?
Yes, a 350mA capacity output will work well on a 210 mA load. This presumes that the old adapter worked well on the load that was connected to it. The load for the old adapter had to be below 210 mA.
Can you use 12v 1000ma instead 12v 150ma?
12v 1000mA means that the maximum output of that unit is 1000 milliamps at 12 volts. 12v 150 mA means that the maximum output of that unit is 150 milliamps at 12 volts. So if you need 150 milliamps at 12v either will do. BUT if you need over 150 milliamps at 12v then you must go for the 1000 mA unit. By the way there are 1000 milliamps in 1 amp.
Can a 12v dc 500mA adapter be substituted for a 12v dc 200mA ac adapter?
No.If it is AC output, it will blow out the power circuits of the DC device.If it is DC output, it doesn't have enough current capacity for the load of the DC device.If you want to power a DC device with a wall wart, make sure the wart is:DC outputCorrect polarity (some have reversible polarity)Exact same voltage as the deviceGreater than or equal to current rating of the device
Can a 9 volt adaptor be used on a appliance that calls for 9volt battery or 12volt adaptor?
No. The person who designed your appliance had a 12v adapter, so when he designed the adapter connector he put a resistor in it to drop the voltage to 9v.
Will 9v 1100mA power adapter work with your 9v 500mA device?
Yes, a 9v 1100mA power adapter work with your 9v 500mA device. The mA number is the maximum amount of amperage that the adapter will produce without overloading itself. At 500 mA the adapter will only be working at half load.
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.
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 i use 9v dc with 12v dc?
No. 9 v is only 75% of 12 v.
