[DML] Ohm's Law (Cigar lighter output)



I am so embarrased to even be asking this question as a guy who is 
deeply into telecom and EE but:

How many amps is the cigar lighter -supposed- to put out?? Mine puts 
out around 4 amps. It runs my little air-pump just fine, but of 
course it blows the fuses in my cigar-lighter adapter devices such as 
cell-phone chargers, and mini-disc player power supply. They are only 
rated for 1000 mA.

Do I have a short somewhere, or does it just need attenuated?
If I do need to attenuate the circuit, how many ohm resistor should I 
install? Based on 13.5 volts and 4.5 amps DC measured at the outlet, 
I figured I should put in a 50 ohm resistor.

Now that I've publicly admitted I'm dumb feel free to advise me.
