The sun powers our world. Plants and animals need light for different functions and some, like lizards and snakes, even export the task of heating their bodies to the sun. It should come as no surprise, then, that as humanity's technology advance, it would eventually come to take advantage of this same power source. If you have a solar battery, you need a reliable solar trickle charger.

We are entering the new age of solar power. Not all devices can harness the awesome energy of the perpetual explosion in the sky, but with the simple addition of a solar trickle charger, nearly any device can become a solar-powered, eco-friendly version of its former self.

The solar trickle charger has truly changed the game when it comes to adapting existing technology to the off-the-grid alternative. The introduction of these chargers to the market deserves no less attention than the opening retort of a revolution. But today, there are many solar trickle chargers out there on the market. Which one to buy?

We hope to answer this very question with this article. We will present for your browsing pleasure: the top ten solar trickle chargers on the market today. We will consider the pros and cons of each entry on this list, but first, let's answer some frequently asked questions about solar trickle chargers.

HOW WE REVIEWED

The real test of a solar trickle charger is its longevity. Every item on this list will be able to convert sunlight into stored battery energy (some faster than others), but ultimately what justifies the price is how long the item will last. We considered the range of life of each of these solar trickle chargers as a significant point of comparison.

Also, helped to curate this list based on each solar trickle charger's affordability, efficiency, brand reputation, customer reviews, and of course the unique and key features of each item. Some of the items on this list are better suited to emergency phone charging situations than car battery charges, and so the use of each item is essential to keep in mind.

OVERALL PRICE RANGE OF SOLAR TRICKLE CHARGERS

You can expect to pay between $12 and $70 for a solar trickle charger. The low-end models tend not to last as long, but they also tend to be more compact and designed for emergency use instead of everyday charging. Those on the upper end of the price range might seem too much for some of our readers, but trust us when we say that the more expensive models tend to pay for themselves over time.
