The GoalZero Nomad 7 Plus is a portable solar panel designed to go anywhere you want to go. With a rugged design that's made for attaching to a backpack or hanging outside a tent, the Nomad 7 Plus is as popular for on-the-go charging of phones and tablets as it is for backpackers needing power for headlamps and GPS units.
The rugged design is made of sturdy plastic, and features an optional kickstand that lets you prop it up for optimal sunlight exposure, whether you're using it in the park, on a mountain, or just in your office window sill.
The Nomad 7 Plus features several convenient features, such as automatic shut-off that stops charging when the device is fully charged, an LED indicator that displays solar strength to get the best placement for capturing rays, and power output up to 7 watts through USB.
One of the best-selling solar chargers on Amazon is also the smartest, with the BigBlue 5V 28W Solar Charger boasting a built-in digital ammeter to provide information about amperage for charging speed, and a voltage regulator that offers stable power output for safer charging. In a field full of simple devices, these smarter touches make the BigBlue a great choice for those who want something a bit more sophisticated.
The folding four-panel design offers plenty of surface area to harvest the sun's power, and a zippered pocket keeps your devices secure while they charge. The functional design features industrial-strength PET polymer fabric with grommet-reinforced holes for attaching the charger panels to a backpack. You can also hang it from a tree using four included hooks. Thanks to IPX4 water resistance, it will also survive the unexpected rain shower or errant sprinkler.
Though there are several portable solar panels on the market, the BioLite SolarPanel 5+ is one of the few to come with its own built-in battery, letting you soak up the sun during the day, and save some of that power for charging at night.
The clever design incorporates a 2200mAh integrated rechargeable battery and 360-degree kickstand. The kickstand does double duty as a hook, for hanging the panel on a tree branch or tent, and a pair of anchor points also let you attach it to the outside of a pack with carabiners for solar collection on the go. The BioLite solar panel also has a handy sundial on the front to help you find the best position for the free-standing panel. The charging panel is also weather resistant, with a tough protective layer on the panel and covers to keep moisture out of the unit's USB output and micro USB charging port.
The best-selling solar charger on Amazon is the BearTwo Portable Solar Charger 10,000mAh. Thanks to a solid feature set and an affordable price, the Beartwo comes in black, but is also offered with blue, green or orange accents.
Aside from that, the overall design is basic, but functional, with a chunky, easy-to-grip body and a single 2.5 x 4.5-inch solar panel. Built-in functions include a charge-level indicator, a triangular cutout for attaching a carabiner or lanyard loop, and a flashlight.
The power bank's 10,000 mAh should provide up to five full charges for a smartphone, and it can charge two devices at once, thanks to a pair of USB power outputs. Weighing just 7.4 ounces, it's also the lightest solar charger we've listed, making it the better option for ultralight backpackers and anyone else who wants to keep the weight down in their everyday carry.
For a uniquely useful charging solution, it's hard to beat the BLAVOR PN-W05 Solar Power Bank. In addition to being a ruggedized solar-capable power bank, it also has Qi wireless charging, giving you the built-in capability to charge many smartphones without plugging anything in. Just put your wireless-charging phone onto the power bank charging pad and watch your battery fill up.
The 10,000mAh external battery pack is also rich in features, from the built-in solar panel to the integrated flashlight. The hard plastic shell is made even more rugged with rubber-reinforced corners and water-resistant port covers. Underneath that cover, you'll find both micro USB and USB-C ports for charging the power bank, and a standard USB port for power output. And if you use the wireless charging pad and the USB together, you can charge two devices at once.
How to choose the best solar charger
Solar chargers tend to fall into three styles: Power banks that have a solar panel attached, stand-alone solar panels for charging outdoors, and a few options that combine these two, pairing larger fold-out panels with a power bank.
For on-the-go use, smaller power banks may be more convenient, but any solar capability offered by putting a single panel on the face of a portable battery is going to be limited. Solar-capable power banks can recharge entirely by sunlight, but it may take up to a week of sunny days to do so. Instead, these pocketable power backups are meant to be charged like any other power bank, but exposing the charged bank to regular sunlight will help keep the battery topped off.
These external batteries do boast some added functionality thanks to built in flashlights and other features, but the solar aspect isn't the main selling point.
For serious charging when in nature, you'll be better served by one of several solar charging panels, which offer more surface area and more-efficient power generation. These portable panels can charge a phone or tablet in a matter of hours, and most are designed to attach to the outside of a backpack, so you can charge phones or cameras while hiking.
