yes this will work fine
Using a 12v 600ma source is allowing 12 volts and 600 amps of power. If the device requires a 12v 500ma source, the larger source is acceptable. Please note that it will only be drawing on 500ma of the available 600ma.
No, the supplies output is too small. To run a 550mA device a supply source of 600mA and larger would be needed.
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.
no
No, 3200 ma = 3.2 amps
No, because the provided rating of 12volt, 2.7Amp equivalent to 2700 mA (milli amphere) is a much higher as to the adapter said 12volt, 1000 mA (Milli Amphere).
input voltage is strictly according to applications. If use 12V dc adapter power 5V dc device, the 5v dc device would be damaged.
It will work fine as long as the supply voltage matches the device. They both must be 12V, and both usually must be the same type-- either AC or DC. The supply current must be at least as much as the device requires.
No, twice the voltage applied to a device that only requires 6 volts will probably destroy the device. When a manufacturer of equipment states a required voltage for a device that is the voltage that must be used.
Yes, 1 amp is equal to 1000ma and it will be able to operate a 850 ma device.
YES
No B/c ur unit Circuitry design for 1A u can put in 2A MAX 15A may cause burn ur unit
