Thanks for the help! I ordered a 4.5 watt charger, I don't know how well it will work, however I can always add more if needed.

This is the 12v blower that mounts above the engine in a bay window bus. I'm wanting to order a solar panel to power the blower and use it to cool my greenhouse, but the blower I have doesn't have any info on it. Thanks! Greg
