They can also come in handy if you experience a prolonged blackout and don’t have traditional power to fuel your devices.Unlike batteries and portable power banks, portable solar panel rely on access to the sun. The 7 portable solar panel chargers rounded up here are some of the highest-rated ones you’ll find on Amazon. AmazonA popular option from JackeryThis portable solar panel charger from Jackery literally only takes seconds to set up: Just push out the two kickstands and you’re good to go. What sets this charger apart from the others is that it’s up to 23% more efficient at generating energy from sunlight than conventional panels. It also has rubber handles that make it easy to carry.Promising review: “We purchased this initially for use when we go camping with the Boy Scouts to keep the Jackery charged for cell phone charging for the leaders and this did not disappoint. It charges our 300W Jackery box up quickly and works well. We also love that it is adjustable to the angle of the sun so you can get peak sunlight on the panels throughout the day.” — Ex-Chief JimAmazonA solar charger that’s powerful yet quiet Yes, this portable solar panel charger is pricier than many others you’ll find, but if you plan on spending a lot of time off the grid, it might be worth the investment. The 100-watt panel can charge not just small devices but also portable fridges, camp stoves and lanterns. It also comes with a canvas bag for easy carrying.Promising review: “Bought this mainly for emergency use, but also occasional off-grid needs. The first test was to hook it up to the power station and run a RecTeq Bullseye wood pellet smoker/grill. Using the two together, I was able to get a net positive charge while running the smoker. (In other words, it was charging faster than the smoker was drawing power.) This was on a mostly sunny/partly cloudy day, with a little bit of shade on the panel. Granted, the power station and solar panel are brand new, but they seem pretty solid and well-built. So far it seems like a good investment. My only constructive criticism so far is I wish the cord from the solar panel to the power station was a couple of feet longer. I'm guessing it's about 4 to 5 feet, an 8-foot cord would be really handy, but it's not a deal breaker.” — Douglas D.AmazonA weather-proof portable solar charger that hardly takes up any spaceWeighing less than three pounds, this is one of the lighter portable solar panels you’ll find. It’s perfect for charging small tech devices, like phones and tablets. It’s also waterproof, so if it rains or you spill something on it, you won’t be completely screwed. Promising review: “I'm really impressed with just how fast the solar panel alone charges. I tested my tablet and it was working pretty quick. I love that it came with two chargers too. Also if you want it to charge faster get a fast charging cable cord, it makes it go even faster.” — StaceyAmazonA flexible, lightweight portable solar panelThis portable solar panel charger is only 5 pounds and ultra thin, which for its size, is super lightweight. It’s pretty flexible, so you can fit it to a curved roof if you need to. There are pre-drilled holes and connectors, making installation easy. It promises to work well on boats, RVs and trailers.Promising review: “I purchased a 100-watt flexible just to see what I'd be getting for $100. This panel total blew away my expectations! Durable as a rock, and I'm getting an honest 90 to 95 watts, which is, in my experience, about as good as it gets. I'd really like to do the TV test and blast it a couple of times with a sledgehammer. No doubt it could probably withstand it, but I love it too much to try...Definitely Recommend this 4 lb powerhouse of a panel!” — DennisAmazonA 120-watt portable solar panel that works even in bad weatherNot only is this baby water-proof, it can convert up to 23% of sunlight into usable energy, which will charge your devices even in bad weather. It folds right up and is easy to carry, so you can bring it anywhere you have to go.Promising review: “I needed some solar panels when I go camping. It's extremely wild there. I left it out and it gathered energy pretty quickly. I used it all day long and it worked fine. Took me a little bit to figure it out because I am not good with technology but I got the hang of it after a little bit.” — Steve GuerraAmazonA 200-watt 12-volt solar panel charger for off-grid RV campingIf you’re serious about off-grid RV life or camping, it’s worth it to consider a portable solar panel that’s powerful enough to provide enough energy for all your needs. While this one is an investment, it’s built to last 25 years and comes with a 5-year warranty. Promising review: “Picked this up to support RV life when we don't have power. It's a little heavy, but it is easy to set up and connect to the RV. I like that it has a protective case and that the controller is directly attached to the backside of the panel. It easily keeps the AGM battery system charged up so we have the power we need for 12VDC applications. And since it is not attached to the roof, we had the ability to put it in direct sunlight and run a cord to the battery if the RV happens to be parked inthe shade. Works great for us!” — DavidAmazonA solar charger power bank with a flashlight The four panels outfitted in this solar panel charging power bank are seven times more efficient at converting sunlight into energy than single-panel solar battery packs. It’s waterproof and also comes with a super bright flashlight.Promising review: “The product is very reliable. Even when there is cloud cover it keeps charging and the capacity being high means I can have at least three charges from the start. Took this for a hike and it was very helpful for me and my group. Also, the light is a bonus, very powerful. Highly rate this product.” — SarveshThe original version of this story was published on HuffPost at an earlier date.Trending In ShoppingMore In Shopping
