sure, no problem! The power supplying device is rated as to its MAXIMUM current delivering capacity, so 100ma being less than 650ma, you could run up to 6 of those devices in parallel with that adapter.
You should not try to run a 650ma device with a 100ma supply though.
No, if the device needs 700mA of current, your power adapter cannot supply adequate current.
Yes, you can substitute a 6V 600mA adapter for a 6V 100mA adapter. The important thing is to match the voltage (6V) while ensuring the new adapter can supply at least the same current (milliamps) as the original, to avoid damaging the device or causing underperformance. In this case, the 600mA adapter has a higher current capacity, which is safe to use with a device that previously used a 100mA adapter.
No. Both the voltage and the current are too low.
No. The adaptor will overheat.
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.
Using a 600mA adaptor instead of a 500mA one could potentially supply more current to the device than it is designed for. Depending on the device's circuitry, this can lead to overheating and damage, especially if the device is not designed to handle the extra current. It's generally safer to use an adaptor with the recommended current rating for the device.
To transfer data from an SD card to a CompactFlash card using an adaptor, insert the SD card into the adaptor and then insert the adaptor into the CompactFlash card slot on your device. Use a computer or device with both SD and CompactFlash card slots to copy and paste the files from the SD card to the CompactFlash card.
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.
Yes, there will be no problem with this adapter. The 1 amp device will only be drawing half of what the adapter can produce.
No the voltage gap is too wide. If the higher voltage is used there is the possibility that the connected device might be destroyed.
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!
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.
