Solar powered battery tenders

No, not for the tesla.

Do these work? They have a long tail of 1's in amazon reviews saying they are total shit.

Another concern is whether they can overcharge the battery. I'm thinking of this one because

a) It has a micro controller to avoid overcharging
b) Battery Tender should know WTF they're doing?

No idea whether 5W vs 10W...
