It’s also super lightweight at only 0.76 lbs and measures relatively compact at 16.5 x 11 x 0.08 inches.  It’s super easy to transport and fits even the tightest spaces of your vehicle.

Like most products on this list, the Suaoki comes backed with a built-in blocking diode. This feature ensures your batteries are protected from discharge, especially during the night when the charger’s voltage tends to be lower.

One issue we had with the Suaoki is it does have a high direct voltage output.   It comes up to as much as 19V, which means that you risk overcharging your car battery. However, it’s not a big deal as you can always get a charge controller to regulate this for you. A charge controller is also relatively inexpensive, so again, it shouldn’t be much of an issue.

Another issue is minor and is more about the mounting. Although the solar panels come with pre-installed holes for mounting, the kit doesn’t come with anything else. It means you do have to purchase suction cups separately, but then again, these are relatively inexpensive.

In short, if efficiency is your top priority, the Suaoki solar car battery charger is a good option

to consider.

What to Consider When Buying a Solar Car Battery Charger

best Solar Trickle Charger for Car Battery

Solar car battery chargers have certain features to watch out for, and here are three of the most important ones.

Efficiency

  • Efficiency is a key consideration in any solar-powered product, so much more with solar car battery chargers.
  • The best solar car battery chargers are those that can still harness the sun’s energy despite not being exposed to direct sunlight all the time.
  • Efficient solar car battery chargers can also power up during less sunny days, such as the winter months or on stormy, cloudy days.
  • We recommend looking to choose a solar car battery charger with at least a 20% efficiency rating.

Power

  • Power is another key consideration, especially that car batteries’ power requirements are different from other devices. In most solar devices, the highest power is usually the most recommended. With solar car battery chargers, you want to find the perfect balance of power.
  • Most solar battery chargers have powers that range between 2 to 18 volts, and anywhere between this range is fine. The lower ranges tend to charge slower but are safer for your battery as it doesn’t run the risk of overcharging. The higher ranges naturally tend to charge quicker, but the risk of overpowering is higher.
  • In short, if you’re wanting fast charging, go for higher voltages but ensure that these have integrated overcharge protection. If you prefer the lower voltages, be prepared to be patient in waiting for a complete charge.

Reverse Blocking Diode

  • A reverse blocking diode is a solar charger feature that basically enhances its safety and efficiency. It does this by ensuring that solar energy collected is retained even when the charger isn’t in use. It also protects energy from leaking even if the battery hasn’t been used for quite a while. Because you normally wouldn’t need to frequently charge your car battery, this feature is important.  The last thing you want is a drained solar car battery charger when you need it the most.
  • Don’t be confused when you see product descriptions stating “reverse charge blocking diode.” This is just another term for a reverse blocking diode, but it’s definitely the same feature.

Solar Car Battery Charger Frequently Asked Questions

best solar car battery charger Frequently Asked Questions

Are there different solar car battery charger types?

  • Solar car battery chargers come in two forms.
  • The first is a solar car battery maintainer. Car batteries need to maintain an optimum level of electricity in them. As the name implies, the solar car battery maintainers function to maintain the battery’s power level. This is especially useful in instances where your vehicle is parked for a long time. The solar battery maintainer‘s role in this instance is to keep your vehicle from completely losing charge.
  • The second type is the solar car battery charger. These are generally meant to be stronger as they can fully charge car batteries instead of maintaining their existing level. They also generally tend to charge your car batteries quicker. These types of batteries are ideal for use when you’re on the road in remote areas where a power source is difficult to come across.

Why should I buy a solar car battery charger?

  • Solar car battery chargers have many benefits. The most important of them are described below.
  • Solar chargers are eco-friendly and sustainable energy sources as they have no harmful emissions, and they harvest their energy solely from the sun.
  • Solar car battery chargers prolong your car’s battery life by maintaining it at its optimum charge levels and preventing it from completely discharging.
  • Solar car batteries are convenient. You can store them in your car for use when needed, anytime, and anywhere.
  • Because they get their power from the sun, solar chargers do not have ongoing costs.

Do solar car battery chargers work even when it’s cloudy?

  • The answer is both yes and no. There is no clear black and white answer to this as it all really depends on the charger’s make.
  • Most solar car battery chargers are equipped with intelligent technology that allows the solar panels to charge despite low sunlight. However, some do not work in low sun conditions. Some solar panels do not charge during winter, fall, or even when shadows block direct exposure to sunlight.

Conclusion

A solar car battery charger is a great back up gear to have in your car at all times. It’s useful in maintaining your car’s optimum battery levels, which effectively ensures that your car always performs in top condition.

Our favorite for the best solar car battery charger is the ECO-WORTHY 12V 10W Solar Car Battery Charger. It’s easy and safe to use, portable and has an ample power level and efficiency. It also comes with accessories for a hassle-free setup. To top it all off, it comes at a price point that won’t break the bank.
