Product Description

POWOXI Solar Trickle Battery Charger and Maintainer for 12 volts battery daily

When traveling away, the Car needs POWOXI solar battery charger for maintaining 12 volts battery daily. You'd never have to worry about the battery drain out anymore!

Why Use POWOXI Solar Trickle Charger?

1. When the car is not in use, the car battery power drops down.

When the car is turned off, the battery is connected to the car. More than 30 body control modules on the car still consume power even when the engine is turned off, such as anti-theft alarms, warning lights, and anti-theft locks.

2. If the car battery always runs low, it will make the battery die faster.

When the car battery is short of power for a long time, it weakens the storage function of the batteries and even kills the battery. Because the car installed consumable devices like a monitor and alarm system, they will drain out battery even don't drive a car. That's why after a long time sitting your car can't start up.

Benefits of using POWOXI Solar Cell Trickle Charger:

1、POWOXI solar charger maintainer and battery charger are for maintaining a 12-volt battery daily. You'd never have to worry about battery drain out anymore!

2、Efficient solar panels absorb sunlight and convert it into electricity for charging 12V batteries. No electricity bill is required!

3、Solar chargers don't consume battery power as they are equipped with anti-reverse diodes that prevent the battery from reverse-charging. The solar charger won't overcharge or damage the battery.

4、Solar charger is perfect for cars, trucks, motorcycles, campers, RV, boats, tractors, lawnmowers, farm equipment, and most 12-volt cycle batteries.

The unit is maintenance-free and will protect the battery against the discharge process that occurs naturally within a lead-acid battery.

Do I need to disconnect while driving?

You don't need to disconnect. Our solar panel has overcharge protection circuitry built into the panel, prevent reverse charging.

Can solar panel charge car battery through a cigarette lighter when the car is off?

Most cars can be charged with a cigarette lighter when the engine is turned off. When it is found that the cigarette lighter can not be used to recharge the battery. You can use alligator clips and cables to connect directly to the battery.

How to know if the solar panel charger is working?

In full sunlight, the solar panel shows a red light. Connect the battery, and turn green. If there are no lights, check the polarity.

Can I charge a battery that is almost dead?

It is a trickle charger that keeps the voltage from dropping or recharging the battery, but it is not a fast charger and cannot charge a dead battery. Please use the AC charger to fully charge the battery before using the solar panel.

Choose a solar panel that works for you!
