That would be better in terms of wattage
The thing is you probably want one with a regulator and a way to hook it up.
Looking at some of the ones in the amazon link and ebay it looks like some can be hooked
in via the OBD 2 port . That's a connector that normally is used for smogging and car
diagnostics its on the drivers side next to the kick panel right below the dash.
That is a standard diagnostic port for all cars so any one of those panels that's for cars and has that type of connector
would probably work. I would get one that is just for a car though if your not into
physics or somebody doesn't come up with another solution.
The BMW one is pretty expensive but its probably certified.
This one plugs into the OBD2 port but I would prefer more power from a bigger panel
Its pretty cheap though.
That ebay link has a bunch of them.
I assume you take your car to work and it spends a few hours in the sun during the week.
