The BigBlue SolarPowa 28 stands out as our top pick in terms of efficiency and portability. It unfolds into four panels with ease and boasts significant solar charging capabilities both in direct sunlight and cloudy conditions. It's exceptionally light, making it easy to hang or prop on various surfaces for an optimal charging angle. Additionally, it includes three USB-A outputs, allowing you to charge multiple devices simultaneously. When not in use, the charger folds compactly, fitting in most backpacks, with a secure velcro closure and a convenient pocket for cables and accessories.
However, the BigBlue SolarPowa 28 does make some compromises for its lightweight design. The lack of kickstand legs makes it challenging to angle towards the sun effectively. While its 20.9 ounces make it lighter than most in its class, a few more ounces for improved usability would be appreciated. Despite this, it remains an excellent choice for those needing consistent and reliable solar charging in a compact and affordable package.

The X-Dragon 20W is the most budget-friendly high-wattage panel we tested, offering reliable and fast charging speeds. On sunny days, its high conversion rate outperforms pricier models, and it fares well in cloudy conditions too. With two USB-A outputs capable of 3 amps each, it can handle charging any USB device efficiently. The panel folds out from the size of a notebook into three segments, with a zippered case to store cables and accessories.
The X-Dragon’s design, however, includes a pouch that causes the panel to sit unevenly when laid flat. While it’s a minor inconvenience that can be remedied by propping it against an object, it adds unnecessary bulk. Despite this, its affordability and performance make it a fantastic option for portable solar charging.

The FlexSolar 40W provides a robust output while being straightforward to set up and pack away. Unfolding instantly into six panels, this model offers an ease of use that doesn't compromise on wattage. It includes a DC output for quickly charging power stations, as well as USB-C and USB-A ports for smaller devices. During our tests, it outperformed other panels with DC outputs.
While heavier than other portable options at nearly 3 pounds, it remains more lightweight than most 50+ watt panels. The lack of protection for outputs does raise durability concerns, but it hasn’t posed significant issues over extensive testing. The FlexSolar 40W is a cost-effective and portable choice for various solar charging needs.

The Goal Zero Nomad 5 excels in portability, making it an excellent choice for backpacking. It’s extremely lightweight, durable, and thin, easily fitting in a backpack. The kickstand leg aids in angling the panel towards the sun, improving efficiency despite its small size.
As expected for a 5-watt panel, it doesn't charge as swiftly, and it’s designed for single-device charging. There's no dedicated space for cables, but for those prioritizing portability, this minimalist design is advantageous. It’s well-suited for backcountry trips or everyday use without adding bulk.

When it comes to larger panels, the Jackery SolarSaga 100 is unparalleled in both performance and value. This 100-watt panel is more affordable than competitors, lightweight, and easy to use, excelling in both full and partial sunlight. Its rapid charging capability makes it ideal for quickly powering electronic devices, irrespective of weather conditions.
The SolarSaga quickly folds to a compact size and boasts a light 10.3-pound weight, making it easy to transport. The fold-out legs allow for easy positioning to maximize sunlight exposure. Equipped with USB-A, USB-C, and a DC output, it offers versatile connectivity options. The rear zippered pouch provides convenient storage for cables and accessories, adding to its user-friendliness.
Despite its light weight and foldable design, the SolarSaga 100’s single-fold construction results in a larger folded footprint. However, if you seek a high-capacity solar panel with excellent value, the SolarSaga 100 is an outstanding choice.
