The amperage rating (800 mA) of a wall power transformer/converter is simply the maximum current that the unit can supply, so the 300 mA device will only pull 300. It's okay to use the 800 mA rating. On the other hand, the device requires 6 V, and the transformer is rated for 5 V. Most of these Transformers will give slightly more voltage than they are rated, but don't count on it. It might work and it might not, but it isn't dangerous.
On the other hand, you shouldn't use a transformer with higher voltage unless you are willing to risk damaging the device.
Of highest importance is to make sure the + and - polarity of the transformer and the device are the same as each other.

How do you compute for the cost of energy consumption per applliance?
Appliances usually have the consumption (Watts) noted on the device. If not: You can buy a device for indicating the power consumption, it fits in the wall socket, then plug in the device and note the reading. Electricity is normally charged by the Kw - hour Say the reading is 800 watts (microwave) = 800 / 1000 = 0.8 Kw Multiply by time in use (hours) Say 10 minutes = 10 / 60 = 0.167 hours Then: 0.8 Kw * 0.167 hours = 0.133 Kw - hours Multiply this by your suppliers rate per Kw - Hour, thats the cost.
What device use magnet and electricity?
Electromagnet
What is friction board?
its a device or an instrument that use in laboratory.
How many watts does a hair curler use?
300 w
What device do scientists use to study quarks?
Electron Accelerator
Can you use an AC adaptor - 3v dc 800 ma to replace AC adaptor - 9 v DC 250 ma?
no, must be 3v
Can you use a 9v 300mA adapter on a 9v 200mA device?
No. The adaptor will overheat.
Can you use a 12v 1a adaptor for a 800ma?
Yes, 1 amp is equal to 1000ma and it will be able to operate a 850 ma device.
How can you access Android device by a Macbook Air?
Yes. You can either access that Android device via a micro USB to USB adaptor, or use an app such as AirDroid (doesn't require an adaptor) to connect/sync.
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 a AC-adapter with the input of 230V 50Hz on an electronic device that originally came with an AC-adapter that had an input of 120V 60Hz or would that fry it?
Pretty certainly no; it depends slightly on the type of adaptor - if it's regulated then you'll probably destroy the adaptor and maybe the device it's plugged unto, if it's unregulated then you'll probably destroy the device and maybe the adaptor.
Can you use a 12 VDC 2A adaptor on a 12 VDC 1A device?
Yes, there will be no problem with this adapter. The 1 amp device will only be drawing half of what the adapter can produce.
Can you use an AC adaptor with 9v output and plug it into a device that has 5v input?
No the voltage gap is too wide. If the higher voltage is used there is the possibility that the connected device might be destroyed.
Is it ok to use a 5v 1A AC adapter for a device when the original adapter is supposed to be 5V 500mA - will it damage the device?
Yes - what matters is the voltage - it has to be the same. The device will only draws 1A as needed - the adaptor with higher amp,i.e, 2A is fine. As long as the adaptor has amps equal to or greater than those of the device, it will be ok!
Can you use a 12 v 1000 ma AC adaptor instead of 12 v 700 ma AC adaptor?
Yes, the 1000 mA has more that enough capacity to operate a 700 mA device. If the 700 ma adapter was original equipment with the device it was to charge, then the device is more than likely drawing about 500 to 600 mA. Look on the device's nameplate and you should see the mA draw.
Can a 6volt 600 milliamps adopter be substituted for a 6 volts 100 milliamps adopter?
Yes...(if I'm understanding your question correctly). You want to use the 600mA adaptor on a device that once used the 100mA adaptor? Yes....you can go higher with mA, but not lower.
Without wireless adaptor how to use mystery gift?
You can use a wired adaptor if you're using a game boy advance.
