These super low watt (5 or less) solar devices are more commonly referred to as battery maintainers because although they produce enough juice to keep a battery charged they are not designed to bring a dead battery back to full charge.

Having said that, these solar chargers can be trusted to keep your 12 volt batteries juiced up and ready for use even after extended down time. ATV, vehicle, garden tractor, boat; if it has a 12 volt battery this solar maintainer can keep it healthy.

Sunsei 2.25-Watt Solar Battery Maintainer

Prevent battery drain with solar power.

Place the solar panel on the dash, back window or suction cup it to any window (suction cups are included). Using either the included cigarette lighter adaptor or the battery clamps, connect the panel to the battery and walk away.

Because these panels are designed to work through glass, you can keep the panel inside the vehicle, discouraging light fingered admirers from acquiring their very own solar charger at your expense.

The 2.25 watt output is enough to keep your car battery topped up without overcharging.

"I purchased this for trickle charging the battery on my tractor. It has worked well... maintaining the charge on the battery, making up for the poor output of the old generator on the tractor, and boosting the starting and lighting power."

Coleman 5-Watt Solar Powered Trickle Charger

Want a little more power? The 5 watts that the Coleman produces is sufficient to keep a deep cycle or 12 volt lead acid battery topped up over long periods of non use.

The solar panel is weatherproof and measures a little over one foot square. Reverse current protection prevents the discharge of batteries through the panel at night.

If you'll be leaving the charger unattended for long periods, add a Sunforce 7 Amp Charge Controller to prevent overcharging of batteries.

"My 5th wheel RV has 2 deep cycle batteries and while the RV sits idle and not connected to shore power, the batteries gradually lose their charge. The Coleman 5 watt solar trickle charger maintains them at full charge during these times."
