RonR,

Are you referring to this 12v, 1.5 WATT (not 1.5 AMP) solar charger?

Watts = Volts X Amps
1.5 Watts = 12v x 0.125 Amps

That would be 1.125 Amps

(I'll apologize in advance if my physics and/or math is incorrect.)

I like this 6v/12 AUTOMATIC trickle charger - no over-charging at a slightly higher price.
