About this deal

The Renogy 100W Foldable is an impressively sturdy panel with a beefy aluminum frame and legs. It's just as rigid and sturdy as a panel you'd install on your house — but has a single hinge for transport. Compared to the many thin, slightly bendable solar chargers we've tested, this one feels just about bombproof. Though it's tempting to mount this waterproof beast to the roof of our van, it also has seriously sturdy, fully adjustable angling legs that help it angle precisely into the sun no matter where it is in the sky (or behind the clouds). If that's not enough, this panel put up some of the best energy efficiency results across all the models we tested, rain or shine. You’ll be surprised how many solar chargers don’t do this – imagine going to use your smartphone only to find its flat because your solar panel didn’t have an auto-restart function. With its built-in ammeter and high wattage, the Big Blue solar charger has the potential to draw the most power though it needs full sun to achieve maximum charging output.

The types of solar cells in a solar panel also matter. Though we only recommended portable solar panels that used monocrystalline silicon solar cells, some solar chargers use polycrystalline silicon solar cells or even thin-film solar cells. A monocrystalline panel consists of monocrystalline solar cells, which are currently the most efficient commercially available solar cells. A polycrystalline solar panel is made of polycrystalline cells. In fact, solar panels have been more efficient than other forms of electricity since at least 2013. They last up to 20 or more years in the field, and most, if not all, components of solar panels are recyclable. On the Big Blue Solar panel. I wasn’t very satisfied with it. After sitting in the sun for Four hours,I made a small charge on my iPhone. The Mac book next to nothing. This particular solar panel was not so good either on doing multiple charges at once.I had a friend use it with a cheap flip phone in which had a better bit of charge. I phone, Mac books not so good. Before my experience to use I should have researched the product to what it really could do. All companies claim they have great products until the user sets out into a venture and we expect that company experience to be really accurate. Put it to the test yourself a bit

Whether you’re looking for a solar portable charger or generator, our pick of the best models will ensure you’re never running on empty

The Goal Zero Nomad 50 is a larger solar charger that also wins our award for Best Solar Charger for Car Camping and Best Solar Charger for Basecamping and our Best Upgrade Solar Charger award. At 50 watts, it’s the biggest and heaviest solar charger we tried. But if we were doing a couple of weeks in a high mountain cirque with fellow adventurers and we wanted to cut battery weight while keeping our electronics charged, this is the charger we’d choose.

watts to 30 watts: Many of the portable solar chargers we tested here fall into this wattage range. 20 to 30-watt chargers are great for faster charger speeds while still being relatively portable.When it comes to accessories, there are two main accessories you can use with the solar panels, cords and batteries. What we liked: includes integrated battery that works as power bank, can pre-charge included powerbank, easy to align with sun to get the most efficient charge, designed to reduce overheating (that impacts efficiency) Efficiency and power output are two separate, but related, things. Efficiency refers to the efficiency of the solar cells in a panel and also the panel itself. The solar cells in the panel have a higher efficiency than the overall panel as some of the energy they capture is lost in transmitting energy through the wires and electronics of the solar panel. The most efficient commercial solar cells are around 24 percent efficient. A solar panel or charger, however will likely be in the range of 18 to 21 percent efficient. The solar cells are encased in impact-resistant plastic and the units usually have an IPX4 water-resistant rating, meaning they can handle water splashes but not much more than that. That shouldn’t be a surprise since the majority of portable solar panels have standard USB-A ports with no waterproof cover. Battery capacity

Power output is measured in terms of wattage or how many watts of energy a solar panel can output. The more efficient a solar panel is means it can output more watts and amps from a smaller area. For charging devices you’ll want a solar panel that’s capable of producing at least 5 watts, however many highly portable solar panels produce up to 28 watts of charging power in ideal conditions. Higher wattages do equal more charging power—however, since most of these solar panels still use USB-A style plugs, they can only produce 2.4 amps of current through those plugs. Portability and size Some solar power banks, chargers or generators will have a control to pause charging while the sun is covered by heavy cloud, or at those times the solar panels are covered by shade. With some devices or power banks, this can cause the power bank or charger to “steal” charge from the device it’s meant to be charging, which obviously isn’t a good thing. Many will also have some form of overheat protection, to ensure that huge amounts of hot sun don’t cause the circuitry or battery to overheat, damaging the charger or power bank – or you. It’s lightweight, foldable AND waterproof so it even does a great job in the harshest outdoor conditions. In ideal, full-sun conditions a 20 or more watt solar charger with two (or more) USB ports should be able to charge multiple devices at up to 2.4 amps like most 12-Volt USB adapters used in cars. A more powerful panel should be able to charge more, but the device has to be able to handle higher charging amperages like those that use USB-C connections. Additional features and accessories According to the product listing, the BigBlue Solar Charger is waterproof, however, no specific waterproof rating is given, which made testing this detail a little challenging. Determined to figure out just how far I could push it to the limits though, I started with small spritzes of water from a spray bottle and worked my way up to completely submerging the solar panel section into a bathtub full of water.While most adventurers are looking primarily for a portable phone charger, solar chargers can power:

For a solar charger to produce optimal power while hiking, you’d have to be hiking primarily northbound in the northern hemisphere and primarily southbound in the southern hemisphere — all day, in direct sunlight, and without any shadows from trees or clouds. You’ll meet these conditions in desert or snowfield hiking.

Most people want a solar panel or charger that can deliver at least 2.4 amps, which is the power needed to charge a USB device. What is the difference between a solar charger and a solar power bank? Capacity is impressive, too, running our electric heater on its low power setting for 48 minutes, and making it through the entire Hobbit trilogy on our 43-inch TV, with enough juice left for a 62 minute encore of An Unexpected Journey. That’s nearly nine hours in total. Throw in the extremely competitive price tag, and the Ugreen is fantastic value.
