Product Description

Product Specifications:

Maximum Power: 10W
Optimum Operating Voltage (Vmp): 18.2V
Open-Circuit Voltage (Voc): 22.4V
Optimum Operating Current (Imp): 0.55A
Short-Circuit Current (Isc): 0.59A
Operating Temperature:-40°F to 185°F

Note:

To get the best charging effect, the solar charger panel needs to be placed in a location that is exposed to direct sunlight.

Package Contents:

1 x 10W Solar car battery maintainer
1 x 23.62 in Cigarette lighter plug
1 x 19.69 in Alligator Clips line
1 x 23.62 in extension cable with O-Ring Terminal
4 x Suction cups


Waterproof IP 65 Great waterproof performance. Low Iron-tempered Glass brings excellent waterproof protection for the panel. Note: Can't be immersed in water.	Cigarette Lighter Plug the cigarette lighter into the socket when use it to charge or maintain the vehicle's battery, really plug and play. Note: The cigarette lighter may not work when the automobile is turned off. When starting the engine or driving, you need to disconnect the charger. Avoid power surges to damage the charger.	Alligator Clips Use the red and black battery clamps to charge and maintain the 12 V battery, make sure they connect correctly. Note: The red alligator clip is connected to the positive terminal (+) of the battery, and the black one is connected to the negative terminal (-). Don’t leave the solar charger for a long time or leave it unattended.

Why does the label say 18V?

The voltage range of a 12V battery is 10.8v-14.4v. To charge the battery, the output voltage of the component must be greater than 14.4V. Consider the temperature effect of photovoltaic modules. That is, when the temperature rises by 1 degree at 25 degrees, the cell voltage drops by 2mv. When photovoltaic modules are exposed to the sun, the temperature of the modules can reach below 50 degrees. In this way, the voltage output of the photovoltaic module will drop by 2-3V at this temperature. Therefore, it is suitable to make solar panels with a working voltage of 18V.

Is the solar car battery maintainer trickle chargers waterproof?

This 12V 10W solar car battery maintainer charger is weatherproof, But it should not be submerged in water.

Why is the power tested by ourselves different from the power on the product label?

The parameters we label on our products are the results of testing in an ideal laboratory. Solar panels are affected by many factors. such as the intensity of the light and the angle of the panel put on the ground. However, the intensity of the light constantly changes. In addition, the angle of the light illuminating the solar panel also changes with the rotation of the sun. Please try to test your solar panel under the full sunlight to see, and make sure there is no shadow cast on the panel.

Will panels still charge on cloudy days?

This will also depend on the conditions. If it is cloudy and overcast, likely not. If it is cloudy and bright still, then it probably will charge but it won’t be very much. You can choose our 2.5W 5W 7.5W Amorphous Solar Battery Charger, which can be charged under any weather, and it's not affected by weather and environment.

Really works well

Reviewed in the United States on November 24, 2023

Size: 3WVerified Purchase

I had a problem with the car battery discharging over several weeks when not used. Jump start was a temporary fix but a nuisance. This trickle charger ensures the battery is kept healthy. The car is not parked in strong sun light.

Great solar charger

Use this to keep the battery on my Harlots charged without electricity. Easy to install just clamp on the battery and set it in the sun. It doesn't have to be in the direct sunlight it will work in the shade as well. I haver used the suction cups yet but they look like they'd hold it in place no problem. And fir the money these solar charges work best and fast as well.

Cables shorter than expected

Reviewed in the United States on June 13, 2022

Verified Purchase

When I bought this item over similar solar trickle chargers it was in large part because the description (at the time) indicated a longer than average cable length. To my dismay, when it arrived I learned they simply added the lengths of all 3 connection types together, as if you could use all 3 in series (you can't). The description has since been changed, and I see an image now that lists each length individually (not sure if that was there before or not) ... but someone should not be expected to inspect all the images just to get the full/accurate product specifications.
As a trickle charger, this works just fine.

plug in to the cig power port, made my Prius malfunction

Reviewed in the United States on December 11, 2023

Size: 10WVerified Purchase

I used this solar panel by plugging it into the cig power port. Big mistake. It will make your car lock you out and drain you battery with the radio on full blast. LIke a virus into the car. Now I plug it directly to the battery. I think it is ok now.
