ECO-WORTHY 12 Volt 5 Watt Solar Battery Charger/Maintainer Features and Specifications

The unit is rather compact and lightweight, featuring physical dimensions of 8.07 x 9.25 inches (~20.5 x 23.5 cm) and it weighs 0.76 pounds (~345 g).

Electrical characteristics depend on the weather, season, clouds, etc. but generally, the unit features Maximum Power (Pmax) of 5W, Open-circuit Voltage (Voc) of 22.41V, Short-circuit Current (Isc) of 0.3A, Maximum Working Voltage (Vpm) of 17.9V and Maximum Working Current (Ipm) of 0.28A when tested under standard testing conditions.

ECO-WORTHY 12 Volt 5 Watt Solar Battery Charger/Maintainer features a small solar trickle charger with 57 inches (~145 cm) cord, one alligator clip adapter with 22.8 inches (~58 cm) cord, and one cigarette lighter adapter with 22.8 inches (~58 cm) cord, allowing the user to connect the unit to car's cigarette lighter adapter, or directly to the car's battery.

Since the unit features the built-in protective diode, the unit will not drain the battery when there is no enough light to maintain/recharge the battery.

When the unit is mounted in the car, it can be mounted on the windows using four suction cups (included) or by using solar panel's rear straps to mount it onto the car's sun protective visors.

Note: when the cars are turned off and the key (or key card) is out of the ignition (or the key card port), some cars disconnect the car cigarette lighter port - in such cases, connect the unit directly to the battery using alligator clamps. Also, although ECO-WORTHY 12 Volt 5 Watt Solar Battery Charger/Maintainer is a simple to use unit, when it arrives, be sure to read the manual thoroughly and, if required, to keep it near the unit for future references.

Since modern cars, trucks and other vehicles feature more and more parasite loads that drain the battery while the engine is turned off, ECO-WORTHY 12 Volt 5 Watt Solar Battery Charger/Maintainer can be used to keep the vehicle's battery in fully (or almost fully) charged condition, prolonging its operating lifetime.

Personally, as a battery charger, ECO-WORTHY 12 Volt 5 Watt Solar Trickle Charger should be used for charging only the very smallest lead-acid batteries (up to 12V 4-5 Ah) with the voltage control, just in case.

Long Story Short: If You are looking for a compact and lightweight car, RV, ATV, snowmobile, boat, pontoon, truck, etc. battery maintainer, consider ECO-WORTHY 12 Volt 5 Watt Solar Battery Charger/Maintainer.

However, if You are looking for a dedicated solar car battery charger (or charger kit), consider a product with much stronger and larger solar panels.
