i have an old charger - which charges 3-6 A; and was never able to charge a battery.
the smalles t batteries are 60 WH and even these i could not charge
so i assume this device won't do it either
also note that for charging a car battery, you should supply more than 12 V: 14 i believe is a minimum

A lot of mains battery chargers have intelligent circuitry to provide the optimal charging current, and to test the current status of the battery. I don't think you'd get this flexibility or charging rate from a solar panel.
They'd be good as a preventative measure to stop a battery going flat in the first place, but I don't think you'd recover a dead battery in a singel day with one.
You can buy spare booster battery units if you need an instant fix though.

Long answer: It is a 9 watt device which means it charges at about 12 volts (roughly) and 0.75 amps. Good for trickle charging or keeping a battery charge level. To recharge a battery in a day you'd need 12 volts (roughly) and at least 5-6 amps.
