 In general, vehicles with higher-rated alternators (150A, for example) will handle a given load better than vehicles with lower-rated alternators (60A, for example).  The rating in Amps will be listed on the window sticker, often on the alternator housing itself, or can be looked up using a VIN decoder for your automaker.   In general, vehicles with higher-rated alternators (150A, for example) will handle a given load better than vehicles with lower-rated alternators (60A, for example).  The rating in Amps will be listed on the window sticker, often on the alternator housing itself, or can be looked up using a VIN decoder for your automaker.

-There are no firm rules on how much power you can extract, but these are commonly-observed limits: 
- 
-  * draw no more than 1/2 of rated amps while driving at normal road speeds - this includes the vehicle's own demands (lights, wipers, fans, etc). 1/3 may be a safer rate for continuous charging.    
-  * draw no more than 1/4 of rated amps while driving at slower speeds.   
-  * [[rv:idling#charging|do not idle]] to charge house batteries 
- 
- 
-Note that alternators put out their rated current at higher RPM.((typically highway speeds))  See chart on the right for a Ford Transit 250A alternator.

-See [[https://youtu.be/gDIsOaEI9Wo?t=344|this excellent video]] discussing the output of an example alternator.
