    This charger puts out between 4 and 5 watts at about 18 volts, and drops to battery voltage once connected. That should be enough to keep the battery from going dead during long periods of non-use, without overcharging the battery. At the end of the first day of use, my battery was up from a low of 12.2 volts to 12.8 volts -about where I want it. Time will tell how well it works in prolonging battery life. Delivery was happily two days early.

    The wires are too short. Suction cups don't stick to textured dashboard. No regulation. Worried about over charging. Red led on cigarette lighter connector lights from car battery power so does not indicate that solar cell is working. Solar cell works. Delivery was reasonably fast. Came from Ontario to US. No Tariff detected.

    Solar panel outputs 22 VOLT in direct sunlight. Way better than advertised. However BEWARE! The USB output is not regulated, it will explode your devices if you plug them into USB. Please buy a cheap 10A solar charge regulator for about $6. Then USB will work fine. Shipping took 2 days longer than expected, but not seller’s fault. This is a STEAL for the price! Absolutely buy this! Best purchase you’ll make for $13!
