This solar panel does come with two connectors and alligator clips, but it does not appear to come with the 3-piece SAE cable that some other charging kits do come with. This offers a little less flexibility when it comes to connections. Best Features The first thing to decide is if the solar panel will be mounted in the car itself or externally somewhere (on the roof of your garage for example). OptiMate Solar Panel Charger - best option for most classic cars - fully weatherproof and large enough for year round battery maintenance, can be placed inside or outside car, comes with charge controller to prevent harm to battery and gives charging and battery status info via LED lights, large range of accessories

Some manufacturers use cheap quality material that becomes “warped” from being in the sun for long. ECO-WORTHY uses the best material & unique design to provide 10W charging always. Also, the special design of clips prevents a short circuit from happening. All you have to do is connect the positive and negative electrodes to the corresponding terminals on the battery. The wires are small enough to be fed through tight spaces, such as closed car hoods. The panel can then be laid flat on a surface that receives direct sunlight. This is a connector, found somewhere around the cars steering wheel, out of sight, that you can plug in to, to charge your cars vehicle and do other electronic tasks with. The POWISER is also versatile since it comes with a 3-piece SAE cable kit. This means that you can plug this charger into a cigarette lighter plug if you wish to do so. This charger also comes with suction cups and carabiner clips to keep the panel attached to the surface of choice. ParameterThis comes with a polycrystalline solar panel rather than the monocrystalline cells seen in many other solar chargers. This helps keep costs down, as MPPT controllers are pricier than other types of solar controllers. The main difference with polycrystalline is that these types of solar cells tend to be less efficient than monocrystalline. Best Features The most notable feature of this charger is the 3-piece SAE cable that allows you to have multiple choices in terms of charging methods. The 3-piece kit includes alligator clips, cigarette lighter plugs, and an o-ring terminal. Solar panels can be made from two different types of glass: either tempered or flat plate. The tempered option is six times greater in terms of strength than normal plate glass. As such, it is a much more durable option and will reward you with a product that is much less easy to break. Charging Visualization] The indicator lights of the solar charger help you better distinguish the usage status of the solar charger. Portable mount or stand: you can make or buy a stand for your charger so that it stays where it’s supposed to but also so that you can move it around easily.

For normal 12V car battery maintenance I would suggest you buy as large a solar charger as you can justify (I would wouldn't I?!) particularly if there are battery drain problems. If you exceedthe ratio of 10W of solar power to 100Ah of battery capacity a charge controller is required but you don't need to worry as our 5W Solar Charger and OptiMate Solar Panels all come with a charge controller as standard. Two Charging Way - External battery charger with solar panel can recharge by solar or outlet. Compatible with your iPhone, Samsung, HTC, Nexus, Go-pro Camera, Tablets and other USB devices. More than 1000+ recharge lifecycle. Solar cells based on photovoltaic provide high-efficiency when accompanied by a strong aluminum frame, making it the go-to solar charger for all buyers.

This product is designed to charge or maintain 12V batteries in motorcycles, cars, caravans and boats, as the unit is also weather proof it can be used outside as well so is perfect fro Camping and also charging utility batteries for example for 12 volt electric fencesThe green LED indicator is the best feature of this product, it blinks whenever the battery is charging. The solar charger comes with an 18-month warranty and the best customer service. Pros & Benefits: Higher Efficiency] ETFE has regular bumps on the surface. It forms secondary light transmission, absorb a lot of solar energy, and the photoelectric conversion efficiency is as high as 95%.

The solar charger is made of both – heat and water resistant material, which provides you, all year long protection. Even though it only weighs 345g/12.49oz, making it easy to carry, the lifespan is more than other solar battery chargers.
