Best Solar Chargers

The Hiluckey solar charger is another strong performer on our shortlist. Completed with four large solar panels, it provides the transformation of solar energy with 18% - 20% efficiency rate under direct sunlight. And with 1A input current, it's 4 - 6 times faster compared to mini solar chargers.

The charger is featured with a built-in 25000mAh Li-polymer battery that can use solar energy or be charged by any micro USB cable. Once full, the large-capacity battery can re-charge your phones 8-10 times or tablets 3-4 times on average. That equals about 9 days of use per charge.

The panel has two USB ports and charges your gadgets from the said built-in battery or directly from the panels. Dual USB ports can charge both devices simultaneously with 2.1A speed.

To make the process safe for your gadgets, the solar charger employs overheated, overcurrent, overvoltage, and short circuit protection. It intelligently detects the current of the ports to provide optimal charging output.

If you're using a lot of electronics out on the trail and looking for a powerful battery pack that can be quickly recharged on-the-go via solar energy, you'll be hard-pressed to find a better offering than the ADDTOP Solar Charger. Unlike many other similar models with one solar panel, this one has four of them. And since the unit has an increased number of panels, it absorbs 4x more energy when unfolded.

The solar power of this charger makes 5 Watts and the input current is 1 A. With that, the conversion rate via solar charging reaches as much as 88%. On average, it takes somewhere from 30 to 40 hours to recharge it completely from empty (or 6-8 hours via a 5V/2A adapter). The solar charging speed will be largely affected by the weather and the environment. Since the intensity of sunlight changes at all times, the charging power won't always reach the maximum value. Theoretically, the most optimal solar charging time is considered to be between 11:00 am and 4:00 pm.

BLAVOR offers a good wireless power bank that can be charged either by the mains or the direct sun. Primarily, it should be charged via power outlet (has both micro USB and type-C input port). This way of charging is much quicker and reliable. Just in a few hours, the 10000mAh battery gets full and ready to charge your smartphone for several times.

The blue light is flashing when it's plugged in and green light is on when solar power is absorbed. Additionally, the unit has two powerful LEDs at the front that work in the flashlight mode.

Another extra you'll probably like is a complimentary compass kit. The charger comes with the cute little compass that works correctly and can be neatly attached to the casing of the solar charger. This shows that the manufacturer has really put thought into it and included something that would add comfort and safety to your outdoor adventurers.

The unit itself is manufactured from the premium ABS fireproof materials that are sturdy and durable. They also make the charger IPX4 splashproof, dustproof, and shockproof. The company is really confident in the highest quality of the product, so it kindly offers a 100% money-back guarantee.

If you're in the market for an ultra-rugged, powerful portable battery that can stand up to all your adventures, you may like the Riapow Wireless Solar Charger. At 16.5 oz, it's a very solid unit that looks sturdy and well-built. It offers IPX6 waterproof performance, meaning that wet weather and light rains won't affect its functionality. The inner layer here is made of durable ABS material, while the outer one is of waterproof silicone that covers USB ports and prevents the water or dust from entering.

In addition, the product is high-temperature resistant and drop resistant. The manufacturer has conducted many professional height drop tests (from 3 to 5 feet) and states that even if the product falls out of your pocket or backpack, it won't get damaged. What also makes it an ideal power bank for your backpacking experience is the addition of a strong LED flashlight with 3 modes (flashlight, Strobe, SOS).

In case you're planning an overseas trip, you may like the fact that the Riapow battery bank is 99Wh which is lower than the restricted 100Wh for carry-on luggage. That's why you can safely take this portable solar charger in the cabin and enjoy watching movies on your tablet when on the plane. With it, you'll never run out of charge.

If you're an avid traveler who often goes on long hikes and needs to carry a couple of different devices, you should definitely take a closer look at the Nekteck 21W Portable charger. It's a revolutionary solar panel that boasts a very lightweight construction and, accordingly, is much more portable than most other ones with similar specs. The unit weighs just 18 oz and makes 6.3x 11.1x 1.06 inches when folded which allows you to easily fit it into your backpack without adding heft to it. At the same time, despite being that compact and small, it is able to keep two different gadgets at the top battery level.

Owing to the SunPower Maxeon charging technology, the Nekteck panel far outperforms the majority of conventional solar chargers. The unique Monocrystalline cells of the panels increase the efficiency of charging by up to 21% - 24% compared to the standard 16% - 18%. As a result, the Nekteck 21W charger can juice up your mobile devices just as quickly as a normal power outlet.

Yet, you should bear in mind that because the Nekteck solar charger does not have a built-in battery, it won't store power for a long time. That's why you should not leave it in the shadow if you do not want it to lose charge. However, if you wish to store some power bulk, it is a wise idea to invest in a good backup battery (power bank) that can be charged during the day and then transfer the power to your phones at night.
