Best Solar Battery Charger On The Market

Solar car battery chargers keep your vehicle’s battery charged from the sun so you can go just about anywhere you want. The unit attaches to your car’s battery and either plugs directly into the outlet to create a direct current or is connected to an inverter that converts the solar energy into a current that can be read by the battery. There are a few models of solar car battery charger kits available on the market today. They vary in quality, so it’s important to choose one that’s made with quality materials and has a good reputation in the market.

ECO-WORTHY 12 Volt 10 Watt Solar Car Battery Charger

The 12 Volts 10 Watts Solar Car Battery Charger will keep the battery in your vehicle, boat, snowmobile, tractor, etc. charged and maintained while you’re out for the day. This is a solar panel charger, not an inverter. It must be connected to a battery that is fully charged at all times.

Power on the go with the alternator-powered accessory outlet for your car. A small solar panel on top of the outlet powers a built-in 3,600 mAh rechargeable backup battery, and gives you a cigarette plug-powered USB port for charging mobile devices on the road. The panel also serves as an emergency light when vehicle power is dead and has a pair of LED indicators that show the battery’s status. Please note that the protective plastic film on the panel surface is supposed to peel off.

Emergency start-up power to start your car. When the battery is discharged and a jump start is not available, or you are in need of additional power beyond the standard battery life, this ultra-compact, 12V Adapter can be used to recharge the batteries in your vehicle up to 32 times. Simply plug one end into the cigarette lighter socket in your car and the other into the USB port on this portable charger. The 6000mAh capacity provides enough charging power to run a laptop 8 hours without being plugged into a wall outlet. The kit comes with a jumper adapter cable to connect to dead terminal batteries for jump-starting.

With a cigarette lighter adapter, it gives you a choice for either DC 12V auto power or USB plug power. There are 4pcs PVC suckers attached to both ends of the temperature probe, perfect for different kinds of weather and surfaces; On the other hand, 1 pair of battery clips makes the temp meter more portable.

When it comes to making sure the battery power of your electronics is safe, prolonging battery life is just as important as increasing its capacity. A perfect example of this is a battery’s blocking diode. This diode protects your electronics from reverse discharge and maintains the battery life, increasing its usability.

SUNAPEX 10W 12V Portable Solar Battery Charger

This solar charger adopts 22% crystalline silicon material which is more efficient than the commonly used activated carbon to reduce the charging time. The charging area is folding, which makes it easy to carry out and position in the sun, and absorb sunlight more efficiently. ETFE material transparency reaches up to 95%, which can enhance the output of solar power by 10%. Besides, its honeycomb structure is good at using heat radiation to effectively prevent the appearance of a temperature difference when working under sunlight.

With advanced firmware, charging efficiency is increased by 10%-20%. A built-in sun power module enables the device to charge 24/7. It also provides multiple protections such as overcharge protection, over-discharge protection, short circuit protection, overload protection, reverse polarity protection, etc.

The solar panel junction box has a three-color LED indicator to help you monitor its working status. Solid blue-Receiving sunlight, output normal; Solid red-Connected to the battery, charging; Solid green-Battery is full; No lights on – Short circuit occurred.

In order to reduce the internal chipping of solar panels and reduce the conversion rate, the state-of-the-art coating technology adds a layer of PCB. This helps to make the panel more robust and heat-resistant. We use waterproof and heat-resistant ETFE instead of PET, which extends the service life by 5 times. The cables are thicker and more durable than competing brands.

The Slim Panel meter super thin, PCBA thickness is only ~1/3 of the rigid panel. With integral short circuit protection.

Solar Battery Charger FAQs

Can I leave a solar trickle charger on all the time?

Connecting a solar charger to your car’s battery is simple and can be done continuously, all the while recharging the battery cells. As long as there is electricity in your vehicle’s battery and cigarette lighter, it can be charged without being plugged in.

How do you use a solar battery charger?

There’s no installation required. All you have to do is simply attach it to your car’s dashboard or place it underneath the windshield. Some solar chargers are wired directly to the battery, while others feed power to the battery through the cigarette lighter/power socket.

Battery trickle chargers, which are sometimes called smart chargers, do not fully recharge a dead battery, but they do keep them on a partial charge. This prevents a battery from losing power that would otherwise be used up if the battery were left unconnected.

Wrapping Up 

A solar panel car charger is the quickest and easiest way of charging a vehicle off-grid. What’s more, these devices are globally available these days for a modest amount, so you can spend more on something else (like an electric sports car or a boat). Overall, this is an investment into solar you will not regret!
