We noticed that solar chargers generally increase in price based on their wattage and the number of solar panels they feature - for example, prices in Goal Zero’s Nomad line increase with each step up in wattage: 5W, 10W, 20W, 50W and 100W. You need to think about what’s best for your needs and the devices you own, as well as your price range.

You can fold up the solar panel and store it in a bag when it’s not in use, and it features a kickstand to angle the solar cells towards the sunlight while you’re charging. If you’re in a shady area, this solar charger pauses charging and automatically resumes when sunlight returns. Below, we highlight highly rated solar chargers in a range of sizes with varying capacities that align with expert guidance - keep in mind that output is often measured under ideal conditions, which in this case often translates to lots of sunlight. Experts recommended looking at device compatibility, power capacity and size to determine the right model for you. Since we don’t test solar chargers ourselves, we rely on expert guidance and our previous reporting about how to shop for them in order to highlight the best ones. Shopping How to pick the right space heater Best solar chargers Solar power banks, on the other hand, store generated energy in built-in batteries, so they can charge devices even when there’s no sun.That means that if it’s shady, solar chargers cannot charge anything.

While many people refer to all charging devices built with solar cells as “solar chargers,” there is a distinction between solar chargers and solar power banks. The solar cells harness energy from the sun, which is converted into electrical energy, the type of energy needed to power devices like phones, tablets and other electronics, said Mazumder. Solar chargers feature built-in solar cells that resemble the solar panels you’d see on the roof of buildings or houses. To help you find the right solar charger for your needs, we consulted experts about the benefits and drawbacks, as well as how to shop for them - we also rounded up highly rated models in a variety of sizes and power capacities.

Mazumder, a professor at the University of Illinois Chicago’s Department of Electrical and Computer Engineering. Solar chargers are beneficial because they can help repower devices wherever you (and they) are, harnessing energy from the sun and converting it into electrical energy to power phones, tablets and other electronics, explained Sudip K.
