Hello all. I have a question that I hope you can help me with. Is there a difference between the bmw trickle chargers and the aftermarket ones? They sell at bmw for $69 so its not bad. My buddy says they are $30 at auto parts store4s and just as good. Your thoughts?

 

their the same product, because i went to harbor freights and its $30.00 and bmw sells the same product for that price.

 

I have both of these units and they work exactly the same:

I bought this one from Ebay: (This is the same unit that BMW sells with their name on it.)

This one is available from Autozone or Ebay:

Both units work exactly the same and do an excellent job of maintaining the battery in a fully-charged conditon.

 

I have the second one, I purchased it at Autozone. Works Great!
