Solar Panel and Charger

The USB solar charger is a small battery that provides electricity for your smartphone and other small electronic devices. It is also a great way to charge a power bank , or conserve energy.

We spent more than 60 hours evaluating 12 models before coming at the same conclusion: a Match USB Solar Charger is the most dependable portable solar charger. It is able to charge your devices and also keep them charged in the event of an emergency or there’s no power.

We discovered that the BigBlue USB Solar Charger to be the strongest and the best solar charger for portable use we’ve test. It also comes with three output ports (as opposed to the two that are on other chargers) and the weatherproof port rescuer as well as a vast, soft array of images to record every ray of sunlight.

This model’s energy output may be comparable to other models, however, it’s lighter and smaller than other models. This makes it simpler to fit in a backpack, daypack, or an emergency kit.

We also like the X-Dragon SunPower Solar Charger 20W if the BigBlue isn’t available. It was second to our top pick in terms of power output during the daytime. And it did a little better as the sun began to peek out at midday.

Although this model will be charging multiple devices in the same manner as our top choice the X-Dragon isn’t equipped with the convenient extras, like the additional charging port or the port protector that makes the BigBlue stand apart.

Solar Charger

If you’re planning on making a long-distance camping trip or traveling to an area without reliable power, utilize a USB solar-powered charger. These chargers are great for keeping in your emergency kit. In these circumstances, the best solar chargers are able to charge a phone as large as the iPhone X. A few hours of sunlight is all it takes to charge the battery. The USB charging station might not be the most suitable option in every situation. You could instead think about a USB Power Bank, USB-C Laptops or AC-powered laptops. These power banks are small enough to fit in books that are paperbacks and don’t depend on weather conditions.

However, a battery pack or solar charger can only be used only with USB or USBC devices. This makes it less appealing for these options for those who require power to go off-grid for long time. It’s likely to be using bigger equipment or stationary charging devices such as laptops and televisions. We also have a guide to the top portable power stations.

How to choose your Solar Panel Charger?

We began by selecting only the best-selling and most highly reviewed listings on Amazon and also reviews from review websites and sites that focus on outdoor and technology. We didn’t take negative overall ratings or low scores as a reason to reject a product However, we removed those with a pattern or high number of negative reviews. These included those that mentioned issues such as slow or inconsistent performance, warping, bowing, power-related problems, and other defects. These essential features were analyzed prior to sending any model to test:

Charging and power output

Because you might not be able to charge a single phone at a time using a USB solar charger with lower than 10 watts, we only examined models with at or above 10 Watts. We preferred models with greater power, but we did not want the charger to weigh too much.

We eschew chargers with only just one USB charging port. The two output ports are favored by us, which allows the charging of another device or share the power with other devices. Extra ports are a plus. Each port must draw at least one amp in order to charge the iPhone X in just three to four hours.

The ideal portable charger should be small enough that it can fold out solar panels and then store them in a daypack. It shouldn’t weigh more than an iPad. Also, we found that a larger surface area was better at capturing sun’s mysterious rays during cloudy days, so we excluded models that had more than two screens. We have previously seen disappointing results using smaller brick-style models with batteries built-in. We wanted a solar charger to weigh too much for hikers and backpackers. We didn’t weigh anything greater than a pound on the models we tested.

Reliability and warranty

We looked over the website of the company and then contacted customer service to confirm that each model was produced and sold by a reputable brand. They were also offered for sale, which is likely to sell quickly, and covered under warranty for up to one year.


We also looked at any additional characteristics that a charger may include. A solar charger can be made easier by using a magnetic closure, as well as the built-in kickstand, if it’s capable of generating electricity and charging up to three devices.

The majority of chargers we tested had the USB-to-Micro USB cable. However some chargers (like Anker’s 3-foot cable) were more durable as well as more sturdy than others. Some chargers had carabiners. Although the carabiners were not heavy and bulky, they loved the possibility of hanging them from backpacks or tents.


The solar chargers that cost more than $100 do not have significant advantages over those priced below $100 or they’re too heavy and bulky for casual campers or emergency kits. On the other hand solar chargers that are priced low generally do not provide enough power or recharge quickly enough to be worthwhile.

We’ve had to contend with chargers that were too fragile or don’t charge at a sufficient speed. We ended up with four chargers that meet our criteria for maximum output, weight, size, availability, nice-to-have and price. The first top choice, the Anker fast charging support PowerPort solar light, was compared with three chargers.

  • Electric solar charger Eceen ECC-626 13W
  • SunPower 20WXDragon Solar Charger

What Solar Panels and Charger we test?

The most promising models were evaluated in the California during a humid July week. It is possible to obtain more power if you go closer to the equator, or under clearer skies. We’ve tested chargers under ideal conditions before, in sunshine regions. This time, we wanted to see how they perform for urban dwellers further north. To ensure that each charger performed under the same conditions, we ran head-to-head tests. We measured the maximum power output and power output of every charger throughout the day. Additionally, we determined how consistent power production was when the charger was confronted with passing clouds.

Fastest charging and maximum output The panels were installed shortly before noon. This is the time of day when the sun is at its highest point on the earth. A weatherproof port rescuer and a vast, soft variety of photos to capture every ray of sunshine.

Then, we linked each one to a PortaPow 3-20V Double Standard Usb Sensor and load testers to determine how much power they could produce during the hottest time of the day.

Total power: All candidates were also placed in a four-hour period in the middle of the day to recharge the Anker PowerCore 20100 batteries. The cumulative power produced was measured with a PortaPow power monitoring device attached the power banks as well as a solar charger.

To ensure to ensure that the results were accurate, we used the four Drok load testers and drained each battery with our PortaPow energy monitor. The numbers we obtained allowed us to know how much a tablet or phone could be charged when left in a dark room for the same period of time.

Consistent power: we tested the ability of each solar charger to restore full power after being shaded, emulating the effects of the passing of a cloud over. We used the same setup and waiting until the meters reach at least a few Watts before closing the chargers. The chargers were opened again when they had reached zero.

Then we waited for their full power to come on. The test was passed by all models. However, in the past tests, some solar chargers, particularly the most expensive ones could not bounce back. This is a huge issue for us. It would be a shame in the event that your phone or solar charger was left outside for a whole afternoon in order to soak up some juice while you go hiking.

We evaluated each model’s size the fit, quality, and size in person. To accurately weigh each model We measured its dimensions after they were folded and folded. Solar chargers usually consist comprised of two or four panels joined to a nylon-woven backing.

Wires are hidden within layers of nylon, and the charger is stored in a pocket at the end. The majority of solar chargers come with an Velcro closing or magnetic closure. They typically have riveted loops or holes along the edges, allowing the user to attach the charging device your camping tent or backpack.

The nylon’s quality and stitching was the same across all models we examined. These panels can withstand weather, so they are able to be stitched in the edges without any additional cover. Although the sizes and weights of the models differed when we got all the models in hand, it was clear that the basic designs were the same enough for us to avoid any variances or select our preferred.

How do you get the most from your solar charger

The simplicity of solar power is one of its most valuable assets. Solar panels require only little maintenance. Most solar power can be cleaned using a damp cloth.

To maximize the power output to maximize your power output, angle the panels correctly. Your angle for the panels in relation to the ground must be approximately equal to the latitude you are in. There could be seasonal variations.

The angle will be more steep if you are farther in the direction of the poles (and the summer) than you are. Average angles in Winnipeg is approximately 41.1 degrees. In Key West, it’s around 22.1 degrees. Even if the angle isn’t perfect it could boost your power production significantly. The LA Solar Group Calculator will assist you in finding the optimal angle. Before leaving the building, snap a photo of your setup using your smartphoneand try at replicating it wild. For support the panels, utilize an hiking boot.

BigBlue solar charger BigBlue solar charger features an opening on the top flap which can be used to store your smartphone while it charges. The black pocket on the top flap could be utilized to place your phone away from direct sunlight, if it’s too hot. It’s best to put your phone on the bottom of the panels, in the triangular space that is between the ground and the prop or shading it with something else to keep it from overheating.
