## Description

The solar panel aims to keep the 12V battery at an appropriate storage voltage by converting solar energy into electrical energy. The portable solar charger is light in weight and small in size, and comes with pre-drilled holes for easy installation. The included alligator clip and cigarette lighter, o-ring terminal, meet different needs. Reminder: 1.If you use an alligator clip, please separate the clips before connecting the wires to avoid short circuit. 2. This product is a trickle charger & battery maintainer for batteries and cannot be used as a fast charger! 3. The better the sunshine, the higher the charging efficiency. 4. If conditions permit, place solar panels directly into the sunlight to maximize efficiency. 5.Don't use the solar charger when the car is starting and running so as not to cause damage to the solar charger.

Review: Works great for long term parking/storage of trucks - Been using this for about a year now to keep my battery topped up in a RAM 1500. Truck mostly sits and doesn't get driven much so this is a great solution where you're parked too far away from a plug in trickle charger or don't want to run unsightly cables.
Review: 30 Watt 12 Volt Solar Trickle Charger for RV or Car Battery - This solar panel is slow charging my truck battery and is able to keep it maintained. I am running 2 Garmin dash cams (front and rear) while the truck is parked. I leave these cameras running 24/7 for the security of my truck when parked outdoors. The cameras will save the video if there is any disturbance. The two cameras when standby and simply monitoring pull about 1/2 Amp from the battery. Over a number of days when the truck is parked the battery can start to run down because of the dash cams. This panel in full sun light is putting out about 2.4 Amps. On a bright cloudy day it is putting out anywhere from about 0.8 Amps to about 1.8 Amps depending on the density of the clouds. In most cases during the day this panel is maintaining the cameras to prevent the battery from being run down. When it is putting out more than about 1.5 Amps it is trickle charging the battery. The vehicle phantom current from its own electronics is about 0.06 Amps average. The user manual indicates after about 2 weeks of vehicle non use the battery may be run down. When parked for more than a few days the battery should have a charger connected to it. -- In most of the Japanese vehicles the 12 Volt cigar lighter socket turns off with the key. With most of the US vehicles the 12 Volt cigar lighter socket remains live. In some of the Japanese SUVs and trucks they offer both a switched 12 Volt cigar lighter socket, and one that is always on. In my truck I have an always on 12 Volt cigar lighter socket. Also, you can have your dealer wire in a fuse protected auxiliary 12 Volt socket for you. They can also wire in a pair of 12 Volt wires and you can custom connect them to the panel or operate any other type of 12 Volt devices. -- I would recommend this solar panel for battery maintenance. I found with the proper adapters it would be possible to put a number of these panels in parallel to have higher current. I have a friend with a large mobile trailer home and he wired up 20 panels in parallel to charge a bank of 12 Volt Lithium ION batteries. He is able to run his lighting, a computer, an RV fridge, and an HD TV with a sound system. All is using 12 Volts. His cooking and grilling is using propane.

Plus grand que je pensais, mais il entre bien dans un toit ouvrant standard (placé entre le verre et l'entre-toit interieur de mon VUS), vendeur très honnête ❤️ les accessoires et le panneau sont bien construit, facile a assembler et connecter 🙂 pas eu le temps de verifier l'efficacité, a suivre 😉
