Can you use a 9V 300ma adapter to power a 6V 800ma device?

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.


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.


How do you fix a car lighter when the actual car lighter adapter works but when plugging in a GPS or Satellite radio plug it doesnt work?

If the car lighter adapter works but devices like a GPS or satellite radio do not, first check the device's plug for any debris or damage. Ensure the device is compatible with your car's power outlet specifications. If the device still doesn't work, try using a different car lighter outlet or test the device in another vehicle to rule out issues with the device itself. If necessary, inspect the vehicle's fuse related to the power outlet and replace it if it's blown.


Is a satellite radio antenna active or passive?

A satellite radio antenna is typically considered a passive device. It receives signals transmitted from satellites but does not amplify or generate its own signals. The antenna captures the radio waves and sends them to a receiver, which processes the signals for audio output.


For a device requiring DC 12v 1000mA will a DC adapter with output 12v 2.7A also work?

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).
