One note on cheap 12V air pumps:
I have one.  The nozzle broke to pieces in my hand when I recently
tried to pump air into one of the tires in 20degree (Fahrenheit)
weather. (being somewhat stubborn, i did not go buy a decent pump; I
found another pump hose and replaced the whole hose :-)

The moral is:  If you need a -reliable_ 12V pump, don't do what I did,
buy a _good_ 12V pump...
Have a nice weekend everyone....
