It is usually safe to use lower amperage on appliances, however, unlikely that it will have enough power to operate let alone power on.
Yes - it will just take a little longer to charge the device.
A: Disregarding the fact of different voltages there is the power to be concerned 9v x 1A = 9W, 15V X .8 = 12W. THE DEVICE WILL BE UNDER POWER.
no
Yes, 1 amp is equal to 1000ma and it will be able to operate a 850 ma device.
yes this will work fine
I haven't seen a router with infrared port, even if you have one you will not able to use internet because the protocol which is being used by infrared does not support internet calls.
yes-ish... You use it to manage Verizon TV, Internet, Router, and phone calls which ain't free. The download is free but the use is half free.
No. Your portable radio needs 800mA to operate. Your adapter can only produce 400mA. If you make the connection the adapter will rapidly heat up and probably burn out.
Sportcraft / Unicorn Part# 79534 "AC Adapter - 9V/800MA" 9 Volt, 800MA +/- AC adapter See attached image of official parts re-order form and manual.
Yes. The voltage is the same on each. The ma rating of the power supply is the current the supply can handle before burning up. So if your appliance is designed to work on an 800ma supply, an 850ma supply will do fine.
Yes you can. But it may damage your computers power supply.
